Rep: (563)
The second life of LCD displays and monitors


ATTENTION !!!
Due to the fact that this forum is not a professional, but a completely voluntary, and this topic is relatively difficult, a convincing request for beginners: first read the header to not specify the topic of questions, the answers to which there are here. If something is not clear - show the pristentness and reread again, just more closely. I assure that 95% of the emerging issues here have all the answers. The hat is constantly updated and complemented. Therefore, I recommend and not newcomers sometimes look into it ...
Main point
This topic is dictated by the presence of many "excess" in the form of matrices (TFT displays) remaining from laptop and netbooks, tablets, monitors, and even from televisions. Therefore, developments on options for their use are discussed here. The topic is very difficult and requires a big attention and careful approach to the implementation of its projects. Those. "Nakhpom" at best, you can not achieve anything, and at worst - also to block firewood. Better I will do as a teacher - I will try "on the fingers" and professionally deselect various technical details arising in the process of incarnation of one or another idea.
Before we immediately proceed to specific schemes and examples, it is necessary to have an idea about everything that accompanies this, and only then draw conclusions about the possibility of implementing this or that project, so let’s consider the technical aspects.
So, the key concept is the display controller. It is called the "controller", and not the "scoleler", as is customary in common. Scaler (from the word scale - scale, scale) is one of the components of the controller functional scheme that is responsible for scaling the image. The controller is exactly the "piece of iron", which is engaged in the conversion of certain interfaces (HDMI, VGA, CVBS, RGBS) into signals, "understandable" matrix. In the overwhelming majority (almost 90% of the total market), controllers are focused on connecting matrices with the LVDS interface. In order to connect the matrix to the controller, you need to make sure whether the controller supports this matrix, as well as comply with the entire list of conditions that this controller must also satisfy and what else should be on it. The controller itself is actually a "blank", which is managing the firmware. And on how much it approaches a specific matrix, the entire success of the enterprise depends.
How everything should look as an assembly is easier to portray in the picture:

This is the most common scheme for the assembly of such a "venture." There is nothing scarce and super-expensive. According to this scheme, matrixes are connected from all monitors and matrixes with lamp illumination from laptops. If we are talking about the launch of matrices with LED backlighting, the scheme will be slightly modified:
Attached Image
The differences are not global, but otherwise both of the above designs, with the condition of serviceable parts, have a guaranteed 100% repeatability.
Of course, I am talking about the available gland, which is produced in China precisely for homemade structures. On the one hand, this is good - mostly all Chinese controllers are designed for the maximum coverage of available matrices. But it is necessary to note the fact that not all 100% of existing matrices can thus be translated into the project. It is meant that there is a series of matrices that cannot be called universal, interchangeable, etc. There are also very non-standard loners, but pleases that they are not so much. We are talking about matrices with rarely encountered interfaces, "raise" which is pretty difficult, and sometimes impossible. It can be safely attributed to the matrix with purely individual temporal characteristics that were laid in tablets or netbooks (where these matrices stood in the first life). Not every controller is able to give these characteristics because in the overwhelming majority of firmware, all the same on some "averaged" and unified parameters are calculated. Controllers who hypothetically could correctly earn with such matrices are those that with a "TV" on board (will be below the spoiler). Those. Those in the settings of which there is a MAP LVDS item in which there is at least some possibility of choosing from 16 presets settings.

BEFORE BEGINING THE PROJECT
1. It is necessary to stock documentation for your matrix - without it the success of the event is nearing zero. What I mean. The documentation on the matrix is ​​the file in the .pdf format, which is accompanied by the release of the matrix itself. Correctly called Datasheet. It is written in it: from the electrical and optical parameters of the panel itself and the illumination parameters to geometric and installation sizes. There is also necessarily there is data on its interface and its connection scheme. A person without experience without it to connect the matrix will be very problematic. Datasheets in the overwhelming majority in English, very rare, but come across Chinese or Korean. Therefore, do not hope that it will be in Russian - no one translates these things. Datasheets are searched on the Internet through a search engine by tag "[Matrix Name] .pdf. Cancel and look. I want to note that the site panelook.com (he is first found in the search for any matrix) - just the World Handbook and Datasheets just does not distribute so much, only for money. So do not hope for him in the search. You can try to look intolibraryBeyondinfinite site. There is certainly not a panel, but quite a lot of things and is heard free. However, it often happens that the documentation on the matrix is ​​not located - this is not the fault of the forum and not mine, but the manufacturer of the matrix. If faced with a similar situation, try to search for a matrix with the same name (or with a very similar name), but another revision or other suffixes - in 95% of cases it helps. Also in this case, the search for compatible models of matrices is helped - for example, see the sales sites and may be listed there will be compatible part-numbers. Show logic and smelting.
2. Which controller is the best - you decide for yourself, because this is primarily a matter of taste and technical requirements that you set.
3. Before buying something, you need to decide according to paragraph 2 which controller is best for you, and then it is MANDATORY to view the firmware archive available for it to determine if there is a firmware that matches your matrix. If there is no suitable one, no one will write it to you, I guarantee it to you. Whether the firmware is suitable or not, it will become clear to you after reading the entire material.
What matrices fall under the possible implementation:
- The vast majority of matrices from monitors, laptops, tablets and TVs. If we expand a little on what has been said - matrices with LVDS, TTL and RSDS interfaces.
- matrices with eDP interface (from laptops of the middle and upper price segment). However, such a project will be released 1.5-2 times more expensive than with "ordinary" matrices.
- matrices with MIPI interface (these are rather high-quality matrices from some tablets). It is quite possible to raise such a matrix, controllers with a MIPI interface exist, only their cost in China is around $ 180-200. Who wants to - buy and do ...
What matrices conditionally fall under the possible implementation:
- matrices from oldportable Chinese DVD players, televisions, as well as a large number of photo frames. These are the so-called "analog" (more correctly RGB) matrices of very low resolution, often with lamp lighting. More I stayed on them here . In this topic, it makes no sense to consider them because of the almost complete absence of universal controllers for them, the lack of firmware (if there is something else) and, as a rule, it is impossible to recognize the matrices themselves to find out their parameters, because the overwhelming majority of them are noname.
What matrices do not fall under the possible implementation:
- Matrixes with LVDS interface with "portrait" resolution (this is when in specifications it is indicated that the number of pixels horizontally less than vertical, for example, 600 * 1024, 800 * 1280 - Check on the page PANELOOK.COM by the name of the matrix - everything is all write "correctly"). Why I focused on the type of interface - because the matrixes with the MIPI interface, in contrast to the matrices with the LVDS interface, on the contrary, in the overwhelming majority portrait, and the controller is responsible for the "rotation" of 90 degrees, which, of course, has much more intelligence, than the LVDS controller. And in those tablets where LVDs portrait matrices stood, the processor is responsible for the correct orientation of the picture.
- All matrices from phones (smartphones).
- matrices from cameras
- Matrix of plasma TVs. This is so clear from the title of the topic, but since questions arise from time to time, I mark it with a separate item. No iron for homemade for them does not even exist in nature.

As for large television matrices, since the abundance of combinations of technical solutions in them is an order of magnitude higher than that of monitor or notebook computers, the project with them must be approached very carefully. Why - it will become clear after a careful reading of this material to the end.
General concepts about matrices used in tablets, laptops and monitors
1. What do tablets have?
- Matrices come in three interfaces: LVDS, TTL and MIPI.
- The LVDS interface in tablet matrices is 1-channel and can be 6- and 8-bit (depending on the matrix).
- Illumination in tablet matrices only LED. Depending on the type of the resulting matrix, it can be removed by a separate connection of the LED line, and it can work from the built-in frame of the matrix backlight. It is clear that in the first case, a separate driver will need, providing LED current according to data from the documentation on the matrix. Built-in driver eliminates the need to search for external. It usually eats from some fixed voltage (3.5V, 5V, 12V, often the supply voltage has extensive limits, for example from 5-7 to 15-20V). Such illumination in budget plates is not found.
- The current consumption of the matrix panel itself for the 7 "matrix in white light is about 100mA. That is, at 3.3V supply voltages (in tablet matrices always), the panel consumes 0.33W of power.
- Matrices come with a widescreen resolution of 800 * 480, 1024 * 600, 1280 * 800, 1280 * 720, 1366 * 768 and "square" resolution of 800 * 600, 1024 * 768.
- Matrices are with "portrait" and "landscape" resolution. Ie, for example, there are 1280 * 800, and there are 800 * 1280. Technically, they are completely different and not interchangeable matrices.

2. What is in monitors.
- Matrices in monitors are in the vast majority of two interfaces: LVDS and RSDS. It is extremely rare, but still there are matrices with a TTL interface and even matrices with a VGA and DVI interface are noticed.
- The LVDS interface in monitor matrices is 1- and 2-channel. Single-channel LVDS is usually found in square matrices with a diagonal of 15 ", rarely in 17". However, starting from 17 "and the 2-channels are usually applied above. In premium monitors 23" ... 27 "- there is a 4-channel. LVDs interface in monitors is always 8-bit. Exception is some very old monitors small diagonal (11 - 15 inches) - There are 6-bit matrices and modern premium monitors in which even a 10-bit interface is seen.
- Illumination in monitor matrices is CCFL (luminescent, 2- and 4-lamp - edge, less often, in large diagonals there can be 6-8 lamps - Direct) and LED (from 1 to 4 ... 8 LED groups). What CCFL is that LED backlight in monitors involves the application of the standard backlight driver. It is usually combined with a monitor power supply and is controlled from the Mineland. From the lane, Enable (or BLON) signals (allow) and PWM (or DIM_B) (brightness adjustment) arrive at it. Sometimes in old models there is a DIM_A - analog adjustment when the brightness depends on the voltage level.
- Power consumption by the matrix panel from 1.5W (15 "square) to 4.5 ... 5W (22-23" widescreen). Matrix panels are powered by 3.3 or 5V, depending on the matrix model.
- Matrices come with a widescreen resolution of 1366 * 768, 1440 * 900, 1600 * 900, 1680 * 1050, 1920 * 1080, 1920 * 1200 and "square" resolution of 1024 * 768, 1280 * 1024, 1600 * 1200.
- Matrices are ONLY with "landscape" resolution.

3. What is in laptops.
- Matrices are "square", i.e. with a 4: 3 ratio (800 * 600 and 1024 * 768) and widescreen with a 16: 9 ratio (1024 * 600, 1280 * 720, 1366 * 768, 1600 * 900 and 1920 * 1080) and 16:10 (1280 * 800 , 1440 * 900 and 1920 * 1200)
- The backlight may be luminescent (one linear or g-shaped lamp) and LED (one LED band, consisting of several groups of LEDs). For CCFL illumination, the driver is used, which stood in this laptop. For matrices with CCFL illumination, laptop drivers almost all interchangeable (electrically not structurally!). For LED backlighting in buoy matrices, a driver is already built into the matrix, and its control and power contacts are displayed on the matrix interface connector. LED matrix without an embedded backlight driver in laptops are extremely rare.
- The interface in notebook matrices can be either LVDS or eDP (for high resolution matrices, retina, yablochniki, etc.). The LVDS interface in low-resolution matrices is single-channel, it can be both 6-bit and 8-bit. In the high-resolution matrices can occur and dual. It is necessary to look at the documentation on the matrix.
Interface LVDS, concepts of bitness and channel
What is meant by "bit depth" and "channel". Let's try a little bit to find out what it is for.
Bit rate
First of all, it should be noted that the LVDS interface is “intermediate” and not “final”. The final data supplied directly to the matrix panel are presented as so-called signals. TTL levels.
The depth (level) of each of the color components (RGB) in the TTL structure is presented either 6 or 8 lines for each color. And since the signal on each line can take a high or low level value, each of these lines is a kind of carrier of 1 bit of information. Those. For the 8-bit presentation of the "green" color in the TTL structure of the signal, the G0 ... G7 lines are used, for "red" - R0 ... R7 and for "blue" B0 ... B7. Accordingly, for the 6-bit presentation of the RGB line will be with indexes 0 ... 5. In addition to the color TTL levels, of course, there are also service lines with various sync signals. So all these TTL signals are encrypted in LVDS signals and on the side of the matrix with the help of special microcircuits are "mined" of them. It should be noted that there are two standards for the location of RGB signals in LVDS - VESA and Jeida. In small tablet, laptop and monitor matrices, in the overwhelming majority, there are no choice of system and these matrices are designed to work in the VESA system by default. It is even possible to argue with some confidence that this system is used mainly in the technique of European and Korean brands (regardless of the place of assembly of devices). The Jeida system is more oriented to Japanese equipment. For example, it employs matrices in Sony TVs, Sharp and oddly enough, also "Korean" Samsung. Moreover, if in television matrices produced by LG-Philips, Auo, Boe, Chimei-Innolux, at least there is the ability to select a color coding system in LVDS, then in some instances of Samsung, Sharp matrices and even AUO (produced by Sony) this choice Simply no - the matrix besides Jeida nothing else "understands."
Without going into deep physical processes, it is possible to consider the differences between the VESA and JEIDA even in the datasheet in the matrix. I'm just giving an example in which these differences are clearly visible. On the left in the picture order of alternation of the color components, and the right - their location in the timing diagram LVDS:
Attached Image

The controller, in turn, "prepares" LVDS signals in its depths. At the very beginning of the development of LCD technology, TTL signals were present in any controller explicitly and then encoded in LVDS using specialized microcircuits. At the current level of chip integration, LVDS signals come out of the controller chip directly without additional processing.
This begs the question: why was all this done? It's simple: to reduce the number of connecting lines. After all, the 8-bit TTL interface contains about 30 lines, and the 8-bit LVDS is only 10. Well, there is a possibility, at the very least, to call the LVDS interface universal.
As probably many have already noticed that, for example, the controller is still, which color of the color to transfer to the matrix - it is set to firmware, and its capabilities are enough to give the highest. Therefore, the concept of visibility relates rather to the possibilities of the matrix itself. It so much that small matrices work with a color depth, described by 6 or 8 bits on color, and the matrix 17 ... 22 inches in the overwhelming majority of 8 bits on color. Therefore, in firmware and mentioned, what it is, 6- or 8-bit. Sometimes the values ​​themselves are multiplied by the number of colors (3 - R, G, and B) and you can meet the concept of 18 or 24 bits - such a classification is used in motherboards equipped with the release of LVDS .. Well, most importantly, what exactly does it affect This is the maximum number of shades that the matrix can convey. 6-bit matrix - 262 thousand, 8-bit - 16,7 million. I have a hurry to calm down, and possibly someone to surprise: if you put two matrices 6 and 8 bit and apply the same picture on them, but prepared with the maximum content of shades for each personally, then you can hardly see the differences in the unarmed eye. How many shades will be able to recognize the human eye, there is no accurate data, and there can be no - people are all different. According to data from various sources, the human eye is able to recognize from 3 thousand to a million shades, and maximum indicators relate to people with relevant professional activities. The remaining on average is capable of no more than tens of thousands. But the main thing - all studies of ophthalmic organizations are not at all relate to LCD matrices, because the matrix is ​​a source of light. And as is known as the range of colors and shades, the human eye is distinguished by the human eye significantly, than the range of perception of "passive" colors. So let everyone accept this information, as far as he allows his "religion".
To find out what kind of bits the matrix, just look at its Datasheet - everything is written there. But besides this can be determined by the LVDS interface. The LVDS interface itself is represented by a certain set of informational and clocking differential pairs. Informational differential pairs are denoted as RXn + and RXn-, where n is a digit (pair number) from 0 to 2 or 3. Thus, the 6-bit matrix interface has such a set of differential pairs:
RX0 (+/-), RX1 (+/-), RX2 (+/-), RXCLK (+/-)
and the 8-bit interface has another pair:
RX0 (+/-), RX1 (+/-), RX2 (+/-), RXCLK (+/-), RX3 (+/-)
This begs the question: "is it possible ...?"
I answer:
- If there is a 6-bit signal on a 6-bit matrix (i.e., leave a pair of RX3 from the controller), then the matrix will show a brutal kaleidoscope of colors, but there will be no correct image. Externally, the picture looks like a color with highly low-lowered athletes (for example, if you put the color depth of 32, but for example, 4 bits). This is explained by the fact that according to the picture above, the part of the full picture does not reach the matrix (after all, the steam Rx3 is not connected) - respectively, part of the video information is lost.
- if you send a 6-bit signal to an 8-bit matrix, the picture will be correct, but too dark and no adjustments will be able to stretch the brightness and contrast to the desired level.
Some fine matrices can work with both 6- and 8-bit signals, and the bitness is selected by applying the appropriate level to a separate special output in the interface, which is designated as SELB or 6 / 8bit. However, as is well known eminent matrices have many clones. So often, even though the pin for selecting the bit rate is, but the matrix does not change its mode - the Chinese can save money on this ...
Often in the parameters of the color depth of the matrices can be found the concept of 6bit + Hi FRC. What is it - you can read on the wiki, but one thing is for sure - this is the optical parameter of the matrix panel, and not the possibility of its electronics. Such matrices are connected via an 8-bit interface.

Canal LVDS.
As mentioned above, the LVDS interface contains a certain set of information and one clocking differential pair. In the matrix of monitors and televisions to increase their bandwidth interface matrix make a two-channel. Those. the number of dif pairs is doubled and one more letter is added to their names RX:
O (Odd) - primary channel
E (Even) - the secondary channel
Then the pairs are called RXO0 +, RXOC +, RXO2-, etc. for primary and respectively RXE0 +, RXEC +, RXE2- (and so on) for the secondary. Those. it turns out that dual-channel 8-bit LVDS works in 10 pairs. Naturally, this is not about renaming pairs, but about a complete change of electronics and an algorithm for its operation. Therefore, one-channel and two-channel LVDS are not the same thing at all, and iron should produce exactly that signal on the matrix that it is designed hardwired for.
You can connect a single-channel matrix to a two-channel signal (and vice versa), nothing will burn. But nothing good will happen.

ATTENTION!!! Different matrix manufacturers often use their own internal labeling of LVDS channels, so do not panic, if you find in the matrix datasheet that LVDS pairs call differently. I give examples of such variations:
RXO = RXIN = RIN
RXOCLK = CLKIN = RCLK
sometimes "positive" (+) and "negative" (-) wires are labeled p (positive) and n (negative). Those. for example, RXIN0P means RXO_0 +.
it can be the replacement of numbers of pairs instead of numbers by letters, i.e. instead of "0", "1", "2" is found "A", "B", "C"
The most fanciful designations come across on the television matrices of large diagonals. For example, in the matrices LG-Philips there are notation of the type R1AN ... R1CN and R2AN ... R2CN, which means RXO_0- ... RXO_2- and RXE_0- ... RXE_2-. Synchro pairs are denoted R1CLKN / R1CLKP (RXCLK- / RXCLK +), etc.
I will separately dwell on television matrices with a diagonal of 32 inches and above.
All universal controllers are designed to use matrices with a refresh rate of 60Hz. This is usually 6 or 8-bit single or two-channel matrices. Many modern television Full HD matrices often go with a 10-bit LVDS interface, and the LVDS interface can be 2- and 4-channel. It is clear that it will not work directly to connect such a matrix to universal controllers. Separate instances of 2-channel matrices have an electrical ability to switch the LVDS interface between 8 and 10 bits - in this case, there will be no special problems with the connection - a sufficient matrix to switch to 8 bits mode. But the matrices having a 120Hz update frequency and a 4-channel 10-bit LVDS interface, without "special vehicles" with a universal controller, simply do not work because it is not designed for any 10 bits, nor on the 4th LVDS channel. What exactly I mean by "special needs" - this will be in the second part of the "caps".
If anyone is interested in digging deeper into this theory - you can start exploringhere. And then you will figure out what to look for (who cares, of course ...).
The most common types of controllers
I repeat once again - we are talking about UNIVERSAL controllers for homemade products.
In China, a huge amount of them are produced and I cannot cover all the models. But among all the diversity there are several types with which success is more likely than with some rare and exotic (but still universal) controllers. First of all, I mean the availability of arrays of firmware and the presence of more or less intelligible manuals.
In any case, divide them into two groups:

CONTROLLERS FOR CONSTRUCTION OF MONITORS
This means that the controllers behave exactly like any computer monitor - "go to sleep" when no signal is input. sleep time - from 2 to 5 seconds.

- controller on chip RTD2660H (or RTD2662) (software designated as PCB800099):
Attached Image

- a simplified version of the above controller, in which there is only an HDMI input (software designated as PCB800661):
Attached Image
An interesting variant of this controller only with sound mentionedhere.

There is another version of such a controller, only it differs in that instead of the LVDS pin connector it contains an FFC 50pin 0.5mm connector and is oriented mainly under the matrix with a TTL interface (the software is designated as PCB800168):
Attached Image

It should be noted that in these controllers, the sound from the stream of HDMI is not extracted.
Not so long ago, a modified first version appeared on the market - it has audio extraction from HDMI on board, audio input "from the side" (automatically connected in VGA and AV modes) and a class D amplifier (most likely with a power of about 2 * 3W) (software The software is labeled PCB800196):
Attached Image
True, the introduction of sound did not pass without a “loss” - the FFC 50 pin connector disappeared from the board and the amplifier settled in its place. Thus, the controller "lost" some clients with a TTL interface and now it can only be lifted through a special adapter, which stands almost like a controller itself.
However, since the park of TTL matrices has not gone anywhere, the variant for these matrices was released as in the previous case (the software, if I am not mistaken, is designated PCB800809):
Attached Image

All of these controllers require firmware using the I2C bus and without the presence of a programmer will not work in any way. The first of these controllers has firmware practically under all imaginable and unthinkable solutions of matrices, the other two in the abundance of firmware are already very trimmed. The latter (the one that with sound) has simply the Spartan set of firmware around the area 20. Another point. Controllers at the RTD2660H chip (RTD2662) for some reason do not complain about the permission of FullHD. According to the description, the chip itself can, but by virtue of some reasons for such a purpose it is used quite rarely. And the Chinese are not recommended for this.

- The controller is only with one VGA entrance and a "jumper" selection of permission to the desired matrix. The cheapest of all options. In addition, he does not need firmware. When choosing (and there are several options, there are several). It is necessary to look at the list of the list on the reverse side of the board and the list of possible feed voltages of the matrix - there are options 3.3 / 5V and 3.3 / 5 / 12V. Another point - often on the charges of such controllers in the list of listed permissions, errors are made in the trimming of some modes, as well as in the signature of the LVDS cutting, the comb is confused "+" and "-" LVDS lines.

When you turn to the work of VGA and DVI inputs audio from external input is also switched to the built-in amplifier. Automatic input selection. Programmable also on I2C bus. The first firmware release (in 2012) there were about 35, but in the second output (in 2015) they were released under 170 pieces. and they were virtually all existing permissions.

- new Chinese invention - controller with eDP output on RTD2556H chip:
Attached fileVS-RTD2556H-V1.pdf(207.08 KB)
There is still little information on it, so I brought the documentation for a version with one HDMI entrance. There are also versions with one VGA input and with three (HDMI, VGA, AV) inputs. But one thing can be approved by reliably - the prices of them are so far very democratic and, I hope that the same remains. For example, a version with one HDMI entrance is in China about 75 yuan. And this means that with all the postal costs, this controller will increase in the amount of 1200 rubles (at the rate of 1 half of 2017). By the way, here is already on Aliexpress the ready version of the monitor controller (no sound):

Controller with digital and analog inputs, and TV tuners on board
How do they differ from the above:
- of course, the tuner. Those. Controllers data represent a complete replacement for any TV offal
- Firmware poured through a USB port, not using tricks with various programmers
- in the mode of operation of any of the external inputs data controllers behave not as MONITOR - if there is time to fall asleep when there is no input signal, it is estimated minutes. From 1 to 5 minutes.
They can be easily divided into two groups:

for reception only analog terrestrial television
Attached Image

for receiving analogue and digital terrestrial television

All of them have quite good multimedia content using USB input with the exception of controllers on TSUM V29 chips.

Since the creation of this topic in the assortment of the Chinese industry, something fresh is constantly appearing, sometimes even replacing the old one. I basically listed them all. But the first detailed report on the successful launch of the universal controller on Android with digital television (it is not quite clear which one) on board providedFDS UA here . Information deserves attention, since many have long been concerned about the availability of such a controller. Meanwhile, the parallel topic about it is gaining momentum. here .

ATTENTION!!! I want to warn you that in all "television" controllers the HDMI input is purely multimedia and is designed to work with sources either HD Ready (720p) or FullHD (1080i). Those. if you expect to use it with a matrix other than 1366 * 768, 1280 * 720 and 1920 * 1080 and connect a computer via HDMI, then you may have problems. What is meant:
If (for example) a 1280 * 1024 matrix is ​​connected to the controller, then when applied to the HDMI inputFullHD and HD Ready signals Everything must work and the horizontal signal should turn around to the matrix horizontal. Those. We apply 1920 pixels on the input horizontal, and the controller displays 1280 pixes to the matrix (from Example). What will remain on the vertical - everything is proportional, i.e. There will be top and bottom to black stripes. The scaler is responsible for this process (in the correct sense of the word) controller. But all this is true for video content. If you are talking about connecting to an HDMI computer, then everything will be not so simple. After all, we (from the example) matrix 1280 * 1024 and to get the most clear image, the signal from the computer should also be the same. In fact, the computer's graphics adapter such a resolution when this controller is connected will not be issued. That's what I meant, calling the HDMI input "Multimedia". To use the HDMI input of the controller in conjunction with the computer, then without the "Bubn" earn except the matrix 1920 * 1080 and 1366 * 768. For a constructor collected on matrices with another resolution, at best you will have to pack the desired resolution using the capabilities of the video card, at worst (if the video card does not know how - for example, the GMA graphics from Intel) - refuse to use as a computer. For more information on this issue, you can find in the second part of the hat under the EDID spoiler.

If you look closely at the photographs of the devices, it is easy to see that all of them are united by the presence of a 2-row 2x15 pin connector with a 2mm pitch for the LVDS interface.In all the above-mentioned controllers, they are completely identical in size and pinout (well, except that some controllers may not have one pin from the power supply (1-3 pins) or masses (4-6 pins), which by the way does not matter. This is how its description looks in manuals for any universal controller:

However, many have not been able to understand this table, so I give a picture of how it looks in kind:

If the situation does not clear up after this either - take good advice: drop this case, it is not up to you.
ATTENTION!!!
For those who are not quite familiar with the concepts of LVDS interface, foster attention: higher under the spoiler it was said that in the interface of the matrix there are pairs of RX signals, and in the controller interface we see the TX pair. Literally this means: Rx (Receive) - "Take", TX (TRANSMIT) - "Transmit". The matrices are "receivers" LVDS signals from controllers, which are essentially their "transmitters". Therefore, the TX outputs of the controller are connected directly to the corresponding inputs of the RX matrix. Those. TXO 0- with RXO 0-, TXO 0+ with RXO 0+, etc. It should be in mind.
One more thing. As it became clear from the previous spoiler, the matrices are of different channels and different bit depths. The controller connector is one and "stuffed" for maximum 8 bits 2 channels. But where and how to connect the matrix, in which the other bitness and one channel, will have to be shown "on the fingers", because ... There is no better to keep silent:

What bit size and which pins to display is the “work” of the firmware and this does not need to be clogged.
The same table will be mentioned in one more place - about the replacement of connectors. I recommend reading even to those who do not want to read ...
The backlight control connectors of all universal controllers are also completely similar, but on some (for example, Realtek RTD2662), there is no leg for adjusting the backlight brightness. Those. The algorithm for controlling the backlight brightness is simply not implemented. By the way, there are generally strange things - the NT68676-2A controller has a backlight brightness adjustment knob and all its circuits are unsoldered, but the adjustment itself is not implemented either in the interface or in the service menu.
Manuals on different TV controllers and firmware files are below the spoiler "Files for download." Therefore, do not ask each time in the topic about pinout connectors, firmware, etc. Take the trouble to find it yourself. You will succeed.
Another and quite serious point. I ask never to write off.
Matrices have orientation. Those. It matters its horizontal side, which is a "riding" of the image. Some tablet matrices (you can even say almost half of their number of models) have the ability to turn the image of the internal electronics by the matrix itself. To do this, there are pins in their interface responsible for reflection of the image horizontally and vertical. Absolutely all matrices from monitors and laptops (netbooks) have such an opportunity. Accordingly, if such matrices were put into some small TVs, they do not cease to be monitor. Large television matrices have such an opportunity, but not all. You can even say that a very small percentage. Why I said all this now. Often (and this is usually happening when the TV is rewritten) the matrix is ​​impossible to expand due to the fact that the body is so arranged or the fasteners are only in certain positions. Therefore, in any author's projects it is impossible to do without a coup of the image. And if this possibility is not provided in the matrix, it can save only a coup of the image by the controller itself. But this opportunity is only at universal controllers with television on board. All the above-mentioned monitor controllers are not a coup. No image. So, when planning your project, please pay attention to this factor.
Yes, I would also like to focus on such a moment - all, buying the above controller, for some reason they forget that it needs something else. And if for a person who is confidently holding a soldering iron, this is not a problem, then for a newcomer - what else. These are buttons and a remote eye. The Chinese sell about such kits costing order.2$

For those who will independently produce a board with buttons, you will find "useful tips" under the spoiler.

Well, perhaps, even finally, a small remark. For all matrices that apply (or applied) in tablets and laptops, there are no controllers that would have only one low-frequency analog video input. So if someone has a desire to make a monitor for an analog video camera (well, for example for the intercom), it will be necessary to consider controllers that have such a video input as "incursions" to VGA or to some other digital. For example, in the first picture, or such a plan:

Variants of the backlight in matrices
Now about one of the most difficult moments - about the backlight. Without going into the types of matrices, I will tell you about what kind of lighting happens in general and what it imposes its imprint on. To begin with, it should be clarified that the LCD matrix is ​​a kind of "sandwich", which includes several components:
- matrix frame at the bottom of which the reflector is located
- backlight system
- light diffusers (diffusers)
- LCD panel
The LCD panel itself is the most "valuable" in the matrix - an image is formed on it. However, the LCD panel is not a source of light - the image is formed ONLY by passing light through. And to see this image - and there is a backlight, which is placed exactly behind the LCD panel (glass matrix). By design, the backlight is:
- Edge - this is when there is a light guide from plexiglas (7-10mm thick) and light sources shine in the end of this light guide. The light guide has embossing in the form of matte points. These points are involved in the reflection of light from perpendicularly running light rays. Their intensity and diameter are carefully calculated and the density of their location depends precisely from which the faces there is light to cover the entire area of ​​the matrix as uniform. At the same time, the light guide is a substrate under the glass of the matrix.
Light diffusers (or diffusers) are located between the LCD panel and the light guide. Their purpose is to provide the most uniform illumination and its intensity over the entire area behind the LCD panel. They are a set of plastic sheets with a specially treated surface - there are both optically distorting and matte sheets.
- Direct - in this case there is no fiber, but the light source itself is located exactly behind the LCD panel. The light source in this case cannot be one - there are several of them, but they are not so much so that they are evenly shone throughout the matrix area. For example, lamps are located at some distance from each other and if not to take measures, the dark and light stripes will be visible in the image. If these are LEDs, stains will be visible. In this regard, the diffusers in such illumination differ fundamentally from the one that is used in EDGE. The first is the sheet of plexiglass (depending on the diagonal of its thickness 2.5-4mm). It performs two functions - support for the glass of the matrix (after all, in fact, the matrix of the matrix is ​​deep and the glass matrix is ​​based on it) and in connection with a specially treated surface - the optical "folding" spots from light sources. Then also lies a layer of diffusers and then all this is covered with the glass of the matrix.
Diffusers usually have the number of plastic sheets 3-4, but it should be noted that only all together, COMPLEX IN CERTAIN ORDER (!!!), they provide a uniform illumination of the entire area of ​​the matrix. Therefore, in the case of opening the matrix (for any manipulations, for example, for repairing or replacing the backlight), measures should be taken to ensure that these sheets lie in the same sequence and the same side (each !!!).
By the type of light source used, the backlight is CCFL (fluorescent) and LED (LED).
CCFL .
In the matrices of monitors, laptops and old tablets, only Edge backlighting is used.
In matrices less than 9 inches, L-shaped lamps were used, which were located along one long and one short side of the matrix. In the matrix of more than 9 - 10 inches used straight lamps. The lamp is located along one long side from the bottom. Very rarely, in the notebook matrices of exclusive models, a two-lamp design was used, while in order to preserve the small matrix thickness, the lamps were positioned side by side, but one after the other (towards the fiber end).
Two or four-particle design was used in monitors matrices. The lamps one or pairs were located along two long sides of the matrix (from above and below). As usual, there are rare exceptions: for example, in some monitors, the diagonal 20 "encounters the CLAA201WA03 matrix with a 6-lamp Edge CCFL backlight - along each of the long sides there are already 3 lamps in it. In the diagonal monitors (above 24") and TVs used multilapampous Direct backlight from direct or U-shaped lamps. These matrices (understandable business) differed great thick.
LED
In the matrices of tablets, netbooks, laptops, monitors and televisions up to 55-58 inches, an edge backlight is used in the form of one band of the LEDs along the lower edge (there are large diagonally from television matrices). LEDs are located in one line tightly to each other, but their inclusion circuit can have the most diverse configuration. It all depends on how many LEDs are combined into a group (called string, the LEDs are included in series) and how many such groups (number of studges) in this strip. The total number of LEDs in such a strip happens from 20-25 in small diagonals to hundreds in large.
A number of television matrices of diagonals from 28 "and are more executed with the Direct backlight. Thongs (they are true are fully fulfilled, rather than in EDGE backlight - for several LEDs on separate bands) are located behind the matrix and several of them. The LEDs used there are fundamentally different from those which are used in EDGE backlight - they are much more powerful, with wide-angle diffusion of light and are not even installed, but at a considerable distance (relative to their linear dimensions) from each other. The total amount compared to EDGE backlit is completely small - in the area of ​​20-50 pieces (also depends on the diagonal).

For what I wrote all this.
The fact is that the output of the backlight control on the controller is represented by 4 contacts:
+ 12V
Enable (enable the backlight level + 3.3V in many controllers, but in television - + 5V)
Adjustment (backlight brightness control, analog output - controlled by some voltage level. In most controllers from 0 to + 3.3V, in television V29-V59 - from 0 to + 5V, in television controller z.vst3463 - made according to the scheme "open collector")
GND
Looking at this list, it is difficult to imagine how to turn on the lamps or LED strips into this connector. In matrices with LED backlit from tablets (not budget) or laptops, the backlight driver is already built into the Matrix electronics and there are contacts in the interface to control the backlight - they are connected without any imaging to this connector (above mentioned about the backlight design in these matrices - It was about the design of the lighting elements of the backlight, and not about the built-in driver). And what about lamps? Or with thongs that need 4-6 lines with a voltage of 30, 50 or 85 volts, and even with current stabilization, and even the necessary power? So in order for such a matrix to light up, you need to apply the backlight driver.
For matrices with CCFL backlighting, there are universal drivers for 1, 2 or 4 lamps.
Attached Image
Those. You can find out how many lamps are in the matrix (this can be seen even by the number of connectors leaving it), buy a suitable driver (they are quite inexpensive) and connect it directly to the backlight control connector of the controller. The cord that comes with it in the kit, just for this purpose and intended. Such a driver is worth about 4-5 dollars, look for ibei or aliexpress by tagCCFL backlight inverter.
However, sometimes the status of the lamp matrix leaves much to be desired. As a rule, in laptop matrices, the lamps have long been sitting. The output is - you can change the lamp lighting onto LED, universal kits for which the Chinese also sell. Just should determine what exactly to take. For laptop (thin) matrices, you need to take a set with a 2mm wide strip. For matrices from monitors, you need to take stripes with a width of 4mm. Depending on whether lamps have been located along how many faces, you should select a kit with one or two LED strips.
Attached Image
Attached Image
I want to note the fact that the design of the EDGE backlight involves the appropriate replacement. Those. If the lamp was only one hand, then the LED backlight must be selected with one strip and put it from the same side. If the backlight was with two faces (no matter how many lamps - one or two each line), then, accordingly, you need to put LED backlight on both these faces. It is extremely recommended to put on only one face (for example in order to save). Light guides used in single-vapor lights differ very different from those that are used in the backlight systems from two faces.
Another pretty important point: in "Luster" (let's call the P-shaped lamp holder) only one LED strip is put, regardless of how much lamps stood in it !!! Exactly. Do not attempt to replace each lamp of a separate strip - except for the structural hemorrhoids you do not get anything else. I explain why. First of all, the width of the "chandeliers" is about 7mm (equal to the thickness of the fiber), and by virtue of the structural and technological and optical features of the bottom of this "chandelier" has a smooth surface of the width of usually 5-6mm. The replacement band has a width of 3.5-4mm and the two bands are correct simply not installed (and light from the LEDs should fall on the end surface of the fiber at right angles). Two strips next to except at an angle will not be lying. For clarity, I give a drawing about what has been said:
Attached Image
Secondly, when the strip falls in the middle of the "chandeliers", the light drops exactly in the middle of the thickness of the fiber. If you shift the strip closer to the edge, which the glass of the matrix lies, then through the matrix you will clearly see bright stains from each LED. Third power consumption. I speak applied to matrices from monitors. On average, the fluorescent illumination of 4 lamps, depending on the diagonal consumes the order of 30-40W. By installing one lane, you will receive a 15-20 t consumption, and if you set two strips, then the gain in power will be zero. In addition, LEDs, unlike lamps, are still tangible. Two stripes in the chandelier will mercilessly warm the light guide and the matrix, because it will simply have nowhere to get warm. The same band confidently falls on a smooth bottom, which carries out heat removal. Fourth - an extra driver ... Why? Well, the last argument, which, I suppose, should forever close this question: the brightness of one LED strip is several times higher than the brightness of the pair of lamps, look at it is very difficult because of blinding. The lamps did not differ.
The length of the LED strips can be chosen for a specific size, and if not, you can take a little more. Due to the fact that these kits are universal and LEDsunitedin groups of 3pcs, then these groups can be cut off. The length of such a "piece" is about 16mm. Those. for a matrix such as 15.4 inches, you can safely take strips for 17 inches and cut off the excess multiple of 3 LEDs. Tag for search on ebay or aliexpress -LED backlight strip kit. The driver that comes with these kits is also designed to connect to the controller directly. A little more about the driver and this backlighthere.
I also want to stop at one moment. Many by ignorance (and maybe because of the economy) are trying to plan to put interior LED ribbons in the end illumination (on the adhesive basis 60 LEDs per meter). I want to warn that they are absolutely not suitable for this purpose !!! Do not try to deceive yourself - besides empty work, you will not get anything good from this venture. First, you will get clearly pronounced light spots and you cannot overcome any constructive triggers. The reason is simple - the distances between the LEDs on such a tape are equal to the size of two LEDs. And secondly, these tapes are not calculated to produce the desired shade (cold white with an admixture of pink / purple) to obtain the correct color scheme of the matrix.
Lamps in designs with Direct CCFL backlighting can not be so easily powered. Only one way is possible - to use the regular driver for the backlight, which came with this matrix in the apparatus where it stood. There is another cardinal way that is described.here. One of the ways of such an embodiment, I explained a littlehere, and an example of such an embodiment (from myself) -here.

For matrices with LED backlight (with the exception of matrices from laptops and expensive tablets) the situation is a little worse - without a regular driver "raise" the backlight will be pretty hard. Those. Or search for a backlight driver for this matrix, or also in China to buy universal. True, it is constructively made of course worse than the native - that's the "universal". The fact is that the "native" driver issues (for example, if in the backlight 4 thong matrix) - four stabilized channels for thongs, and Chinese usually provides them with parallel inclusion. It will work, but it's still not entirely right.
There is one more way - to replace the backlight with a universal LED, which I mentioned above, but this is still necessary only in extreme cases, for example, if the LED backlight in the matrix is ​​partially faulty (by the way, this is quite common).

A more detailed description of the control signals for the inverters and backlight drivers is located below the spoiler on the power of the controllers.
Power controllers in questions and answers
So, here we will talk about one of the most difficult moments - the power supply of universal controllers from the "native" power supplies of future designs. One clarification is about the power of universal television controllers, since things are much easier with monitor controllers. But even if it becomes necessary to resolve the issue of nutrition and those, then after reading this material, I think everything will be clear and all questions will disappear. Let's try to cover all occasions.
Before proceeding to specific examples, it is necessary to understand how the internal supply circuits of the controller are arranged and it will depend on whether this is a simple task or very heavy.
Here is a block diagram of the power supply circuits of any of the V29-V59 universal TV controllers:
Attached Image
As you can see, there are two voltage converters in the controller - the first on the DC-DC buck converter (+ 12 / + 5) and the second on the linear regulator (+ 5 / + 3.3). I have a DC-DC converter ZTP7193i on the V59 board. The linear stabilizer chip is some kind of noname, but initially - it’s still a brainchild of Linear Technology LT1084 (if you are interested, you can search for the datasheet just for it). Here is where these nodes are located on the board (example on V59, but also on V29, V56 is about the same):
Attached Image
The power supply circuits of the z.vst3463 controller are slightly different and look like this:
Attached Image
and here is where these nodes are on the board itself:
Attached Image
In this controller, the power supply of 3.3V is somewhat different: instead of one powerful linear LT1084 stabilizer, the low-power AMS1117 is used to power the controller chip, and the power supply of 3.3V to the matrix is ​​removed from the 5-volt source and reduced due to the voltage drop on the transitions of two diodes in direct power on. Also introduced node power off controller nodes + 5V. For example, now the USB connector, power amplifier and backlight control circuits in sleep mode are de-energized.
ATTENTION!!! Before you run your design on this controller, I STRONGLY recommend that you look under the spoiler of "good advice" and carefully read the power-up item highlighted in red. The same applies to the designs on the 3663 controller.

As can be seen from the diagrams, the controllers can be safely powered not only from + 12V, but also from + 5V. Of course, provided that we do not need + 12V (for example, to power the matrix and (or) the backlight inverter). But even if it is needed, both of these power supplies can be spread and below I will give an example of how.
There is an opinion that it is possible to apply + 5V to the + 12V connector and not to think much. Before doing this, I would advise to think, nevertheless, and here's why. I quote the DC-DC converter circuit (a piece of datasheet and do not pay attention to the indicated voltages):
Attached Image
Arrows, I showed the passage of current through the chip. It is the passage, not the conversion (which is generally the main task of this chip). But the internal circuit of this chip:
Attached Image
So this is how the internal key works when the microchip is not in the mode - this is the question. In a word, whoever decides on this is only at your own peril and risk. I am personally not sure about the long-term use of the chip in this state. But even when she takes off, it's okay too - you can drop it off and serve + 5V directly - you can decide that already.

Another, in my opinion, very important point: the power supply must be obviously serviceable. I think comments are unnecessary here, since it is not difficult to guess what the launch of a controller with a faulty power supply will result in. It can be checked offline (of course with the backlight connected). To do this, you need several automotive light bulbs that are not powerful, for example, from dimensions, and then you need to connect loads and simulate switching. How? Read below - and it will become clear. Well, for examplethistopic to help.

I think, before moving on to the realization of connection diagrams, one should rather chew one rather important point: the difference between the power supplies of monitors and TVs.
In the overwhelming majority of monitors, the power supply when the cord is turned on to the network is always in active mode. Those. "Sleep" monitor mode only applies to the controller and backlight, but not to the power supply - it is always in operation. The "Awakening" signal in the monitors only serves to turn on the backlight - i.e. Only one bus (BLON, BKLT, INV_ON, BKLT_EN, BL_EN and similar abbreviations), which runs the inverter (driver) of the backlight. Summarizing said: The monitor power supply is always in operating condition, and the on / off of the monitor is the result of manifesting the status of the backlight circuit (it works accordingly / does not work) and this scheme is only controlled by one bus. The exceptions make up large monitors with CCFL backlight - they are more like a television BP.
BP TVs differ significantly from the BP monitors. The fact is that in relation to monitors, the difference in power consumption between the duty regime and the working is small - for example, 3W and 40W, respectively. Those. The 40-watt BP in the duty state is calmly working at idle and it does not go beyond its normal functioning. In the TVs (for example with a lamp backlight), consumption in the standby mode is also 3-5W, and in the working - up to 180W (42 inches). It is clear that to make such a powerful idle source work is technically difficult - it simply will not give out normal stresses and currents for the duty regime. In such BP, a separate low-power power supply is installed for the duty mode (its output is called on boards as VSTB, VSB), and the main (powerful) power supply is switched on in a separate bus. On BP boards, this tire is denoted as on_off (sometimes n_f), S / B and something like that. I repeat - only a powerful power source is activated by this signal, from which the backlight inverter is powered, the power supply chain of the matrix, the power amplifier, etc. In this case, this signal is not responsible for turning on the backlight. It is completely another signal for its inclusion. It is indicated in the same way as I called the paragraph above. What is it done for what. If you look at the time diagram, the backlight turns on after all the transactions associated with the supply of power to all TV nodes will be held. Thus, contemplation is excluded on the screen of these most processes. So, we summarize according to the one: the television BP is "on duty" by one source, and the TV is provided to others. It turns on in contrast to the monitor's BP with two control signals - one includes a powerful power supply, the second - backlight. I hope explained it is intelligible.

We now turn directly to the discussion of wiring diagrams.

1. CONNECTION TO BP MONITORS

Excuse my friends, but without theory in any way. Otherwise, everything will turn into a stupid copying schemes and then unnecessary questions. So try to learn what I'm trying to convey.
To begin with, the familiar scheme from the first spoiler, but with minor amendments, what we should have in the end:
Attached Image
The question may arise: why do you need to do this? The fact is that if a monitor is subject to alteration, it is not difficult to guess that its native power supply is already designed for the operation of its matrix and for ensuring the work of its illumination. There is nothing to be wise with external adapters, there is no need to re-buy individual inverters, and you don’t even need to redo the monitor's design - everything is ready only to replace one controller with another, that's all.
The power supply components are usually built ("built", if it comes to monitors with CCFL illumination) according to the source scheme for two voltages - + 5V and also "some". Why "What"? Yes, because it can be from 13 to 22V - it all depends on what kind of supply voltage is designed on the same card inverter of the lighting of lamps or LEDs. In addition, it is not a fact that this is the second voltage enters the controller - most often there is nothing to do there. The controller is usually powered by + 5V, and the matrix - or from + 5V or from + 3.3V. In the latter case, the stabilizer + 3.3V may be either on the controller board or on the BP board, but it does not change the essence - the primary for it is all the same + 5V. But it's not the main thing. The source + 5V is pre-first, i.e. It can issue a current up to 2.5-3A, and secondly, it is the only power supply on which feedback is carried out to stabilize the voltage. And if it remains unloaded, the probability of issuing unstable voltage on the power supply of the inverter is large. Those. Without a load on a 5-volt source, the voltage at the output of the second source at the specified value of 13V (for example) can vary from 13 to 19V. In addition, the backlight power supply is calculated for maximum current 1-1,5A. And if so, then 1-1,2A "eats" the inverter and the power of the controller (if the controller is powered from it) will remain anything. As a result, we simply get a "squid" in the form of triggering protection of PBC from overload. To this not happen, you need to power the controller from the source + 5V. How can I do that? Very simple -apply + 5V from the power supply to the pin of the 5V matrix power selector jumper, which sits on the + 5V bus. What do I mean by this phrase: if the matrix is ​​powered by 3.3V, then it will be pumped straight to the pin or an electrolytic condenser in the output of the built-in DC-DC converter, and if the 5-volt matrix (and this pin will simply be Busy jumper) - then only to the condenser. Or see where the tire is in the controller + 5V and select a convenient place where you can fall to it. For V29-V59 controllers, this is a stabilizer 1084, an amplifier power resistor, etc. This tire is easy enough to bring up the location of the legs of the stabilizer 1084 (the picture for V59 !!! for others - you have to search):
Attached Image
For the Z.VST3463 board, the + 5V bus can be found according to the above mentioned section of the board - this is the throttle pad (where the + 5V bus arrow is stuck).

However, in this connection there is one caveat: we feed + 5V to pin 3 (via a throttle, see the diagram above) of a completely unpowered DC-DC converter chip. Judging by the above internal scheme, nothing terrible should happen. But I still strongly recommend the throttle at the output of the built-in converter to unsolder away from sin. And this is about the V29-V59. But in relation to 3463 or 3663, it is probably necessary to unsolder it. There are cases of "loss" of controllers among forumtsev ...
I think no one will have problems with this connection, because the + 12V source in the designers of the monitors is not needed in any part of the circuit.

Sometimes, it is very rare monitors with a single source. For example, Samsung Syncmaster 225 - he has only one source and he is + 13V. Then of course without options - connect directly to the + 12V connector of the controller. The converter withstands input voltage up to 20V.
And, of course, one cannot say that all of the above applies to absolutely all monitors - of course, there are also non-standard solutions in the circuitry of monitors. In this case, you will need to understand in more detail.
As for the control signals in the power supply unit of the monitors, there are usually only two of them - turning on the backlight and controlling the brightness. Below I will summarize this information in a separate paragraph.

ATTENTION!!! All of the above relates to the fact that I was holding. Those. to the boards, where the feeding portion is expressed as clearly shown in the above schemes. This V29-V59, zvst3463, D3663. As for more recent versions of controllers, it is necessary to carefully examine their scheme for such a possibility. For example, I can say with confidence that the controller Qt526 thus only powered from + 5V will not succeed because the supply chain made it quite differently. Here It is an example of how this has been energized by the controller monitor PSU, on which there are two supply voltage + 12V and + 5V. Moreover, high-current + 5V and + 12V - low current and the entire controller to run from one + 12V could not be articulated by me above reason. Other controllers, deserve attention, I did not - so I can not speak for all manufactured in China glands indiscriminately.
I must say that use native PSU of reworks display certainly much preferable to seek some kind of external adapter. But it is not always easy to do so. Who has the desire - it is the theme, go to the questions will be solved.

2. CONNECTION TO PSU TVS

Why PSU? Because, in addition to the power supply, there can be quite a lot of other nodes on the board, so the TV power units are called the Power Supply Unit. I must say that the second board (often called the Main Board) is correctly called SSB - the Small Signal Board, and this has a definite meaning. The lion's share of the electricity eaten comes from the backlight, and everything else is trifle, and relying on some significant energy consumption by the controller is not worth it ...
Again the theory - without it, alas, no way ...
It is rather difficult to cover all the constructions of television units, therefore I will give the most common ones. Structural Schemes Again. I’ll just make a reservation that I selected the most significant nodes and if anyone decides to let me know that I forgot to draw the circuits of rectifiers and the correctors of the power factor - believe me, I remember that very well. Just the vast majority will not need it.
Well, at the very beginning I will make a note about their difference from the power supply of the monitors: on TVs (diagonals over 24 ") the power supply has a real standby mode. That is," something "in them in sleep mode" sleeps "and only works active mode. What "sleeps" and how - read below.

but). PSU TV on CCFL lamps

As can be seen from the figure, these are the power units that are used in the TVs with a lamp light, the inverter of which is present as a separate board attached on the back of the matrix. A distinctive feature of them is a rather powerful transformer from which the inverter power supply voltages (+ 24V) are removed, in the overwhelming majority of 12V (to power almost all SSB nodes and in the presence of such a power of the logical part of the matrix). It is possible on it more sources for powering sound amplifiers. They are just not interesting to us and I intentionally did not even draw them, because they can not load them in work and it will not affect anything. The duty mode is implemented as a separate low-power source, which always works if the cord is inserted into the outlet. VSTB voltage I intentionally did not indicate because it can meet with a dimension of 3.3V, 3.5V, 4.7V, 5V and it seems even 6B (perhaps in the last I am mistaken, but it could be in very old models). The main power supply (+24, + 12V) works only in active mode, i.e. There are no these stresses in the television mode.
The aforementioned illumination inverter (so-called. Stadalone, the one that hangs on the back of the matrix) has another one, in my opinion a wonderful feature. Almost all 100% of such inverters feed on 24V voltage (in connection with which if the matrices are similar in size, they are interchangeable, I'm talking about the inverter with other characteristics), but this is not the main thing - almost all such inverters have two brightness adjustment entries - PWM (PDIM) and analog (ADIM), which switches between these Special Pin modes. As a rule, ADIM is not connected, but it can always be activated by rearning the wire in the inverter connector and taking measures to switch the inverter to the ADIM mode (in this case it turns on its built-in PWM, which is controlled by the adjustment voltage). So this inverter is easiest to be adapted to adjust the brightness from the universal controller.

b). PSU TV on EEFL lamps
Attached Image
In principle, the differences from the previous PSU there are significant, although this does not affect the project on the basis of a universal controller. The main difference is the matrix there is no separate inverter and it is on the PSU board. Why is that? Because EEFL lamps (External Electrode Fluorescent Lamp) have such a design that they can be connected in parallel and the entire node of the lamp lighting is removed from the matrix with two wires. Accordingly, there is no need in a multi-edged inverter (as in the case of CCFL lamps). All other nuances mentioned above for the previous PSU are fair and for this PSU.

c) .PSU TV with LED backlight
If in the two previous cases, the circuit solutions of the vast majority of TVs did not differ much, then in the case of LED backlighting, PSU circuitry often harbors unexpected surprises in the form of non-standard circuit solutions of developers of a particular brand. Therefore, I present a picture of a strongly averaged average PSU for LED backlighting. Further it will be clear (I hope) that the main thing is not the circuitry, but all the same backlight control signals and supply voltages.
Attached Image
I think that there is nothing special to comment on - almost everything that was said above.
For what I gave these three schemes. To make it clear how the backlight is controlled and how the power circuits are organized, which we will need later to connect our controller.

And there is nothing more to say ... Anyone who has carefully studied everything that was above under this spoiler can figure out how to connect what and where. But in one, I think, I have to help - to unite everything into one “universal” scheme and it looks like this:
Attached Image
Here I have implemented the most successful solution for powering the universal controller, which can also be called universal for almost all PSUs. On the left of the diagram, there is a plot of any television PSU, on the right - a controller (the diagram that was above). Now I explain what elements are installed and why, and how everything works.
So, the key point is washing the controller from the PSU duty voltage. This scheme is suitable for cases when the supply voltage of the duty regime is 5V and it was stated as mentioned above in the paragraph of power from the monitor BP (but only in contrast to the example through a diode). How it works. + 5V pass through the diode and it falls about 0.3-0.5V (it is better to apply with a smaller drop of 1N5817). Thus, on the 5-volt bus of the controller approximately 4.5-4.7V. This voltage is quite enough for the linear stabilizer to give out confident + 3. prov in its output to power the controller chip. The fact is that the voltage supplied to his input should be higher than 3.3V at least 1.1V (i.e. not less than 4.4V). In standby mode, the controller consumes no more than 100mA and this is the load of the PSU power supply unit. When we are "awakening" the controller, it gives the command to output ON / OFF the "Invertor" connector for switching on (...). I did not say to turn on what exactly. And all because if you carefully look at the PSU diagrams of the diagrams, you will notice that they have separate pins to start the main BP and to start the backlight. In our case, we simply connect them together and the controller will successfully launch both.
So, the controller submitted a signal to turn on the backlight and the main BP. At the same time, with the main BP, the + 12V voltage appears, which is connected to a complete power connector of the controller. Next, it is converted to + 5V and it in turn is applied to the diode cathode. In the "right" power blocks when submitting the POWER ON resolution voltage, the voltage at the outlet of the duty unit is slightly reduced (so conceived in the diagram), the voltage on the anode becomes below 5V and the diode is closed, the duty from duty BP is turned off and the controller continues to be powered by + 12V, Going with PSU. It must be said that not all duty duty blocks are absolutely "honest." It is likely that the scheme does not provide a decrease in the voltage of the duty unit in the active mode of the main one. There is no problem even if the diode is not closed, it will not arise. At least the controller will definitely be securely driven from the built-in DC / DC converter, and the BP on duty does not threaten this situation. When switching the controller in the waiting mode, everything occurs in the reverse order. This method is no longer the theory, but a proven and 100% workable (I applied it in my last project, you can find under the spoiler of finished designs).
For cases when the voltage of the on-demand power supply unit PSU is less than + 5V (meaning +3.3, + 3.5V), it will be necessary to apply a circuit withboosting DC-DC boost converter. Converter not at all scarce and completely capricious and stable. Then the connection scheme will look like this:
Attached Image
This scheme allows you to connect the controller to the "standby" voltage of any size from 3 to 6 volts. At the heart of the same theory with the diode, of which I spoke above - it will close when it appears from PSU + 12V and the boost converter remains unloaded - it is not scary for it. The magnitude of the voltage converter installed at the output (+ 10V) was chosen for reasons of a diode drop and a sure 12/5 V DC-DC converter on the controller board. It is not critical and can be from 8.5 to 11V.
Since the connection by the second scheme does not require interference with the diagram of the controller itself, then this option can be recommended to those who are afraid to climb the controller card with a soldering iron and in general to spoil the freight type of controller. Just the second scheme pulls the mandatory acquisition of the converter. By the way, it is not necessary to buy it in China at all - they are and we have the cost of it about 150 rubles (more expensive than in China, but not wait a month ...) ... ATTENTION !!! Configure the voltage of the boost converter to avoid troubles better in advance. This can be done even without load. And then connect to the circuit.
It should be noted that there are additional resistors on these two circuits. Their purpose will be described below in the paragraph about adjustments. However, this scheme applies only to controllers on the V29-V56. For the Z.VST3463 controller, both circuits need to be slightly changed, and the location for connecting additional resistors will look like this:
Attached Image
Those. There will be only one resistor and is connected between On / Off and Adjust. Why it is this way - you can also read about it in the same place in the paragraph about adjustments. For the DS3663 controller resistors are not needed at all.
And one moment. As it is not difficult to notice, all three different PSU variants mentioned above contain the duty pressure supply unit (for example, 5VSB). What it is: This is a low-power voltage source to maintain SSB nodes in sleep mode. Of course, the television circuitry varies greatly and the BP of the duty mode can be used for the washing of low-power nodes (for example, the controller Du and Supervisor), and can be powered by the entire logical part of the SSB and in sleep and in active mode - then it is designed to load up to 2-2, 5a. So in order not to guess and not guess which one you have in stock STANDBY, and the above-mentioned laying schemes of universal controllers have been developed. We are talking about diodes in the supply chains and parallel use of the source + 12V, which accurately has sufficient power.

However, it is worth noting another fact - not all 100% of television PSUs can be combed with the same brush - there are also “ambushes”.
1. It so happens that sometimes on TVs a small diagonal of the + 12V source may not be at all and the whole SSB is powered by voltage, for example + 5V. Powering the controller in this case will need to be done on the principle of powering the monitor PSU. How - I hope you figure it out, all the schemes are above.
2. Sometimes there are schemes in which the on-duty power supply unit has a very small capacity - i.e. sometimes it does not even pull the operating mode of the bare controller. There is a way out in this situation. for exampleheredetailed solution, which was successfully implemented by the questioning forum participant.
3. Another option: in the TV's power supply unit there is also a voltage of + 12V (which the controller does not pull) and a working + 12V (from the output of a powerful power supply unit, which comes to life only in the active mode). Then the power supply method is described.here.
The main thing - to decide on the principle. And in particular - do not hesitate to ask questions in the topic. We will understand and make the best decision.

And more ... I practically anywhere did not show wires of "weight" on schemes. This does not mean that they do not exist. They are and their full! They are everywhere. Do not save them.

3. ABOUT POWER SUPPLY OF CONSTRUCTIONS PRODUCED "FROM ZERO".

What is meant: you have a matrix, there is a controller and there is an inverter as separate blocks. In this case, the easiest way is to purchase a 12V power adapter with a power of 40-60W (current 3.5-5A) and launch it. However, 12-volt power supplies are not as widely distributed as, for example, laptop adapters. There is a solution in this case. It is enough to apply a buck-to-dc buck converter (such assuch a). It is put on the power of the controller itself and the voltage of 12V (i.e. it transforms 19 in 12V), and the backlight inverter is just better to put from 19V (of course if it allows it). In this case, it will heat up less than from 12V. Putting the controller itself from 19V I would not advise. Well, if the board uses a reduction converter chip with a permissible voltage of 20-24V. But it all depends on the manufacturer of the controller - it can set another microcircuit with a permissible supply voltage, for example, 18V and then from the ones attached 19V immediately "PCHIKNET" (and do not give God with consequences). In the area of ​​100 pages of the topic, there is a confirmation of this - in the controller, accidentally connected from 20-22V, the DC-DC chip 12-5V flew and dragged another and important DC-DC to 1.2V, which feeds the controller chip.
By the way, those who know how to hold a soldering iron in their hands can safely use an unnecessary power supply from a computer - it will easily be able to issue 12V 5A, and perhaps the fan will not be needed. It can even be launched on the principle of television PSU (after all, in many of them there is also a separate 5-watt power supply system).
You can also buy not necessarily an adapter (in the classical sense, such as in a black plastic case), but an open power supply. I gave a link to a very good BPby thispost
Everything said in the last paragraph, of course, is focused mainly on designs with monitor or notebook matrices. Because it is necessary to invent a “bicycle” on large television matrices with greater care and miscalculation of power.

And of course, the eternal question of almost everyone who decided on the project. Let's even highlight in bold:
POWER SUPPLY SELECTION
In fact, the question is quite simple. I bring him here only for the reason that not everyone here has gathered with radio engineering education or with amateur radio experience.
Sorry, guys, but again the truisms - without them in any way. For those who absolutely no boom boom with electronics, I will explain on fingers.
1. If the power supply unit is written 12V 5A, then it literally means the following: the power supply module outputs a voltage of 12V to the output and at the same time it CAN eject current up to 5A. Does not issue, namelycan give out !!! Those. the controller can be powered from a power supply designed for at least 1000 amperes, but if the controller eats only 1A, then this 1000 A power supply unit will give only 1A to the controller. Who does not understand - re-read again and again until you understand.
2. The values ​​of voltage and current indicated on the power supply determine itsmaximum power. The power (in watts) at the output of the power supply is equal to the voltage (in volts) to the current (in amperes). Since, as mentioned above, the value of the current current depends on the consumption of its load (and on the power blocks, the maximum current value is specified, which can "give" this power supply), then, accordingly, the power calculated by the above method is also the maximum possible value. Those. The 12V 5A power supply can be in the load 60W, but if you connect a controller that consumes only 1a, the power given to the power supply will be equal to 12W.
And now to the choice of power supply unit. To unequivocally answer this question, you need to be patient and find the strength to read the datasheet on your matrix. So, what serves as a calculation data:
a) Power consumption of the logical part of the matrix. In the datasheet, this (VDD Power) is in the Electrical characteristics section. There may be several values ​​(for different backgrounds of the image) - choose the maximum.
b) The power consumption of the backlight. The same section and sub item Backlight Unit. It is called Power consumtion. We look at the value and multiply by 1.1 for LED backlighting or 1.3 for CCFL. The fact is that this power characterizes the net consumption of the backlight, but we need to lay stock on the efficiency of the inverter.
c) Power consumption of the controller itself in the active mode. Accurate data is not available, but the orientation is approximately 5-6W for the V29-V59 and 8-9W for the Z.VST3463.
We summarize the obtained power values ​​and divide by .... If the planned power supply unit is 12V, it means by 12. If the power supply unit from the laptop is 18.5 (here I have laid the efficiency of the DC / DC down-converter, without which the controller cannot be connected). We get the amount of current in amperes.
It so happens that the data are obtained completely "in the grinding". Then you can either rely on the spare durability of the power supply unit, or after starting the whole structure, reduce the backlight brightness in the service menu (so that it does not work at full capacity). That's all science.
Connecting the control backlight and its adjustment
In many PSUs, as well as in separate inverters, the control voltage is regulated within 3.0 ... 3.5V. From the output of ON / OFF controller, the voltage control signal + 5V is released. In the controllers V29-V59 from the tire + 5V on the collectors of control transistors are 1kom resistors. So in order for the voltage of the inclusion signal and a maximum backlight brightness signal signal to the level of 3.3 ... 3.4V, the circuits above are additional resistors connected to a mass, resistance of 2.7k. Together with resistors from the controller, simple voltage divisors are obtained.
In the controller z.vst3463 and the inclusion and adjustment made severaldifferently. The inclusion signal of the inverter is implemented as a permanent voltage from the key collector on the P-N-P transistor. It is most likely done with the goal of "Causes" of this exit, since it is rare, but inverters are found, which are low input resistance to the backlight input. For example, PSU from Phillips PFL3606 - it has an input resistance of the control input approximately 1k. Therefore, to bring the inclusion signal to the level of 3.3V, you will need to hang on the output of the controller an external resistive divider (you can also construct it from 1 and 2.7k, 2nd and 5.6k, etc.). About the same looksschemeand the controller D3663LUA. The outputs of the brightness control in z.vst3463 and D3663LUA are made almost the same and this will be discussed below.
All the above is just recommendations and perhaps no dividers are needed at all. At least you can safely connect without them - nothing will burn. And only then draw conclusions - we need dividers or not.
The ON / OFF controller output (or BLON at z.vst3463) connects to the inclusion of the backlight of the monitor or television inverter. It can be called BL_ON, BKLT, ENA, B / L_ENA, ENABLE and similar abbreviations from English words backlight, enable. There will be this connection directly or via a divider (if necessary) - can be solved later. And you can simply connect directly directly. If everything works, then there is no divider. But I want to warn that sometimes the signal control is involved in the stabilization of other PSU stresses. Rarely, but it is found (an example - PSU LG 42LN540 - there is an inclusion voltage + 3.5V is part of the output voltage stabilizer + 24V). Then the divider will need.
The output of the ADJ controller is connected to the input of the inverter brightness regulator. It can be called Dim, P_Dim, Dimmer, B / L-ADJ, BL_DIM, BRI and similar abbreviations from the words dimmer, adjustment, BRIGHTNESS. If there are two A_DIM and P_DIM inputs (or b_dim) in the inverter, such a backlight is found in monitors, you can try to connect first to A_DIM and check whether the backlight brightness is adjusted. If not - then to p_dim. The fact is that A_Dim is a voltage adjustment (analog), and P_dim is an adjustment of PWM, and in some inverters analog adjustment (A_DIM) could not be aligned at all.
All the inscriptions that I called may have to search. If they are not on the power supply, follow the home wires of the monitor or television tripe - maybe they are on the mainboard.
Above (under the spoiler about the backlight), I talked about the ways to adjust the brightness of the backlight in TVs and monitors (!!!) there are several, and more precisely four. PWM Adjustment - When the backlight brightness is regulated by changing the width of the pulses, following with a certain frequency, for example, 200Hz, and analog - when the brightness depends on the values ​​of the applied voltage. These are two fundamentally different ways. And plus each of them can have "direct" and "inverse" adjustments. Direct is when the maximum brightness for analog adjustment at maximum voltage at the ADJ output, and for PWM - the maximum pulse width (actually permanent voltage level), for inverse (reverse) adjustment - the opposite. I would recommend before the first inclusion to experience the existing inverter on the autonomous mode (without connecting the controller) for the study of its adjustment and starting levels. In order not to write all possible options for a long time, I will give an inverter launch algorithm:
Attached Image
I hope that everything is clear here - you just need to carefully study it. In the "ovals" in the picture - the results that we need to understand how the inclusion and adjustment of the backlight.
And I repeat: this algorithm involves the launch of the backlightWITHOUT PARTICIPATION OF THE CONTROLLER !!! For fans of unnecessary initiative, I propose to remove the controller away at the stage of testing the backlight so that it is not tempting to connect the contacts on it.
And another very important point, which I did not say. At the time of testing the backlight, the power supply should of course be in good condition and MUST be in operation. Those. in other words, it should be loaded, for example, with bulbs and the voltage on them should be regular. Those. we in this case simulate the normal operating mode of the PSU.
Starting PSU from TVs (in which the power supply itself and the backlight turn on via separate wires) suggests that the power supply enable and light backlight contacts are simply interconnected - in 99% of cases this is enough.
In addition, in order to avoid difficulties at start-up, which can be adjusted to the backlight, I recommend on the first launch to submit to the Adjust regulator inverter the maximum brightness level (according to what you learned from the above algorithm, and if for your inverter ADJ has a maximum with a filed "+ "And ON / OFF also turns on with the" + "filed, it is enough to simply connect ON / OFF and ADJ on the test inverter together, on the controller, while leaving PIN ADJ in the air). The fact is that most universal controllers have direct analog adjustment at the output. If the inverter has adjustment on the PWM principle, the backlight may not be lit, and you do not determine the reason. That's the first inclusion to do as I said. When you start and set up and adjust - then you can separately address the alignment of the backlight - to connect the adjustment correctly and then already conduct experiments, already knowing that everything else works fine.
Most of the television and monitors inverters are adjustable on the PWM principle, and all universal controllers have an analog principle (because they are focused on working with universal inverters, which are equivalent to the brightness adjustment). Consequently, these are two incompatible factors. Cases are possible when at some short section of the adjusting characteristic, changing the brightness of the backlight on the PWM inverter from the applied voltage still occurs (I talked about it in one of my projects), but it is rather an exception than the rule. In this case, you can either even refuse to adjust the brightness of the backlight, connecting the terminals BLON and PWM of the inverter (setting the brightness of the backlight to the maximum), provided that the PWM adjustment from this inverter is straight (or put a PWM on the ground if the inverse adjustment), Either make a not very complex converter analogue in PWM. This will be said at the end of this spoiler.
We continue the "lesson". If, however, you are "lucky" and your inverter is designed for analog adjustment, then in this case you still need to be diligent in order to achieve a result. What is meant. It should be noted that the controller Z.VST3463 brightness control is not as predictable as that ofV29-v59. And even with a large number of drivers and inverters, it is not directly friendly - installed in the "maximum" it still does not ignite the backlight, which normally ignites if the ADJ inverter is connected to BLON. As shown to check, the brightness adjustment output is made in this way: with 90 Output of the chip via sequentially enabled resistors in 4.7k and 1kom leaves the INVERTOR ADJ PIN. In the entire range of brightness adjustment on it, there is no voltage. The reason is that there is an open collector and this chain is needed to "pull up" through the resistor, for example, 2.22 to the BLON output. You can try to connect according to the scheme that I showedhere. So try and experiment ...
ATTENTION!!!
LIGHT BRIGHTNESS ADJUSTMENT IS NOT OPERATIONAL AND HAPPENS IN ALL UNIVERSAL CONTROLLERS ONLY FROM THE SERVICE MENU.
Adjusting the "brightness" from the remote from the normal menu changes only the brightness of the IMAGE, and not the backlight. Who does not understand - re-read again, so you do not ask questions in the subject.

And, since this is a service adjustment, if the monitor inverter has an inverse dependence on the applied adjusting voltage from the controller, I think it should not be a "blow below the belt" - just in the service menu you will have the backlight level specified in the number 90 or 95 (%), and 5 or 10. It does not affect the speed. I do not know how on other controllers, but for example, on the V29, there is even a PWM Invert point in the service, which can change the adjustment characteristic to the inverse. In general, the soil for activity is ...

In conclusion, I would like to focus more on this "topic." Slightly higher, I said that if the matrix (this is about notebooks or tablets) or the inverter has only a pulsed backlight brightness control (PWM or foreign PWM), and the controller only has an analog adjustment, you can take steps to set the maximum backlight brightness. But if all the same adjustment is necessary, then there are two ways to implement it:
1. Production of a simple electronic unit - the duty ratio with a variable resistor (then its handle is simply located somewhere behind, since it is often not necessary to turn it). The method is quite convenient and easy to implement. For example, on the Internet you can easily find the pattern of adjustment of the duty ratio on the timer NE555. There is a minimum of elements there, their cost even in the most barges radio base will not exceed 100 rubles for everything.
2. Making a simple electronic unit, but a higher level - an ADC (analog-digital converter) on the microcontroller, which will convert the analog brightness control of the backlight from the controller to PWM adjustment for the matrix (or inverter) on-line.HereForumartrm.grinko laid out a great adc on attiny13, for which he thanks a lot.
By the way, as such a node works depending on the input voltage, the photo sensor of the environmental dependence on the ambient light can be used with the same success, a kind of "straight array" can be applied. My experience of making such a car monitor is describedhere. By the way, I did at a PIC controller, and not on AVR and the current owner of this monitor from an array in a wild delight.
Of course, it is possible to manufacture such an end to specialized chips (not on microcontrollers), for example, on the same universal TIMERS NE555 or TL494 (reference to the concept of building ADCs I can give), but it will still be more difficult than on the microcontroller. for instancehereversion of such a scheme fromGrishanenko On a dual comparator. Here embodiment of the same idea with a reworked board, there is even a video from areon . By the way, this scheme works "Inverse" - i.e. The greater the voltage at the analog input, the lower the brightness of the backlight. To make the adjustment "straight", it is enough to change the inputs (conclusions 5 and 6) of the second comparator. Here of life hacking vicdu Chinese module with ready to TL494.
If there are any other options for powering (perhaps at the request of members of the forum) - then I will add, if necessary.
3. There are situations where direct PWM controller output, and analog input from the driver, and even inverted. This is what happens, if the SSB which serves a branded card from the monitor or TV, and the backlight driver - the universal Chinese. In this case, everything is solved quite simply.HereI painted this in more detail.
4. And finally, the rarest case, which nevertheless occurred twice during the life of the subject. There is a need to achieve frequency multiplication PWM dimming.Herelink fromandreyvirus on the way to achieve this objective by using Arduino. More specifically: branded lanes outputs a fixed PWM frequency of 50 Hz (and this frequency change is not possible), and the matrix need 200Hz Sharp (and other frequency it simply ignores). That's the question and decided.

Firmware
ATTENTION!!! I wrote this not for myself, but for you. Who does not want to read - make an effort over yourself and still read.
- How to flash the controller (we are talking about universal controllers with a TV on board, since the rest of the controllers are sewn only by "special means"):
File Firmware (ATTENTION !!! Not a folder with a file, namely, the file itself with the .bin extension) copy to the root formatted in FAT32 flash drives, in the controller turned off from the network, insert a flash drive with a firmware file (in the appropriate USB connector) and serve me. If the previous firmware installs the controller when the power is applied to the "Enabled" state, the flash drive state appears (according to its light indicator it can be seen) and then the controller LEDs will begin to "distort". If, when powering the controller is installed in the "Off" state - just press the POWER button on the keyboard or on the remote control. The firmware process lasts approximately a minute, the screen does not shine. After the controller's LEDs "were embroiled", the controller can be installed in the "enabled" state (as it happens after the firmware V59) or to the "off" state (z.vst3463) - it all depends on how the firmware itself is made. You need to wait 10-20 seconds and turn off the controller (or rather the TV) from the network. Turn out the USB flash drive and turn on - the V29-V59 are ready for work, and Z.VST3463 also has to go through the initial installation and setting.
If you try to re-flash or the same firmware or different firmware under the same resolution, the controller firmware to the stage will not go. Thus, if in the case of an unsuccessful firmware (well, for example, do not work or crooked work which it functions, firmware under the Russian version should be changed to the English, or something like that) you need to alter again, you must first flash another firmware with another resolution, and then sew on the right.
And last. Different controllers in different ways are "referring to generations and to USB volumes of carriers. It is not worth the firmware of about 1 gigabyte to use a flash drive to 16-32-64, because the flash drives of this volume are usually fresh generations and may not be perceived by controllers. It happens like this: you turn on the controller, the flash drive blinks a couple of times and nothing happens - the firmware does not go. For firmware, slow flash drives are best suited for 2-4 GB. And then there are problems. Most likely the MCU controllers do not "see" USB's internal controllers of carriers of some brands. So for the accuracy of the firmware (as well as for confident launch of the process itself) it is better to have a small choice from different USB media.
- Firmware does not necessarily have to wear the name of your template. Matrices - a thousand, and it does not mean that they were written under each matrix. You need to look for the firmware that is appropriate to your matrix resolution, bit depth, and the number of LVDS channels. Bit depth, and channel encoded in the names of both firmware SI6L, SI8L, DO6L, DO8L. 6 and 8 - is the bit depth, and SI - one channel (single) and DO - two channels (double).
Look at this nonsense:
Attached Image
I could not even suggest that such a question could arise, but since it did appear, I answer Russian and white:FIRMWARE DOES NOT HAVE RELATIONS TO DIAGONAL MATRIX and are in no way connected with it. Once again: ONLY PERMISSION, KANALNOST and VITALITY. Everything!
- If your matrix comes up a lot of firmware, I recommend to use "smart" search. Those. of firmware with suitable parameters primarily try EEPROM array on the same manufacturer. If you have "exotic" and nothing close to resembling not, then why not try a firmware matrix at the same diagonal.
*** At first glance, these my words go against the twisted two lines above. However, here I put in my words a completely different subtext. For example, you have a Matrix with a diagonal of 18.5 inches with a resolution of 1366 * 768. And the firmware for this resolution is a dozen. There are those that are on the same 18.5 "matrices, and those that are on large television matrices with the same resolution. In this case, it is just better to navigate the diagonally, since many small matrices are interchangeable and have similar time characteristics. But television Just despite the resolution, there may be completely different temporary parameters. Hence the logical conclusion ...And before you immediately sew, "punch" on the Internet, is there a matrix, which is mentioned in the name of the firmware. Because in the archives a lot of firmware in general is unclear under that.
- If you do not have the appropriate firmware, choose the firmware to another bit depth, but with the same resolutionand with the same number of channels LVDS . Then in the service menu, the controller can change the setting Map LVDS, to your matrix properly earned. But with the firmware with the desired resolution and bit depth, but for another channel LVDS This trick will not work.
- Firmware has to do with the supply voltage MATRIX. From the word ALL. It has no hands to reach out and to rearrange a jumper - it should be doing yourself.
WHO DIDN'T UNDERSTAND THAT THIS IS WRITTEN IN RUSSIAN - READ IT BEFORE, UNTIL THE MEANLE WRITTEN REACHED !!!

If you see that in the name of the folder with the firmware specified yet and the power supply - it is nothing more than the fruit sorting themselves proshivkopisatelyami firmware.
- Be careful when choosing a firmware to your controller. In the names of folders with firmware indicated, under which chip controller, as far as the buttons are calculated and which chip tuner. Boards on TSUM V29 and V59 controllers can be equipped with Rafael Micro R840 and R842 tuners chips. You can read the name of the tuner on the shallow chip, which is installed near the antenna connector. Ask in the topic which chip tuner is installed on your board meaningless. It is equivalent to this if you ask forum users to guess which tuner on the board that you keep in your hands. For V56 firmware are not separated, as it goes only with R842.
- Firmware for boards for V56 and V59 DIFFERENT, do not try to cheat with yourself - get a "brick" !!! Verified by one of the forum users.
- IMPORTANT!!! On different boards, but based on the same MCU - different firmware !!! Those. For example, if you have a board based on the TSUMV29 microcontroller, but not La.mv9p, and for example t.vst29-03, then the firmware from La.mv9p is impossible to pour into it, despite the same chip. Any fee with the same chip, but even a slightly different topology (in fact, the scheme) must already have exactly its "native" firmware. The thing is that the microcontroller has many I / O ports through which its connection with the periphery is carried out. So on the same board, the specific leg of the chip can perform one task, and in another board - a completely different, not even related. The algorithm for the work of all ports is just described in the firmware and of course depends on the developed scheme and wiring of the entire board.

Now do the firmware:

I'm not sure that the difference in firmware under 5 or 7 buttons is fundamental, because the service menu contains the choice of the number of buttons. However, KEY7 firmware is much larger than KEY5. Therefore, it is more likely that the firmware will be found under the required matrix in KEY7. And select the required number of keyboard buttons through the service.

The archive firmware on z.vst3463 there is one very interesting text document. However, whether the archive it spoils, so spread apart.
Attached fileHow to make it work with 1366x768 and 1280x800 SI6.txt(1.21 KB)
This suggests that you can use the firmware with one bit rate on the matrix on the other (for example, if there is simply no suitable firmware). After the firmware, it will be used to fix the trouble in the service menu to the desired one. And this is not only for Z.VST3463, for other controllers it is just as fair. In all television universal controllers, LVDS MAP has 16 fixed "cards" presets. But this method acts and even in those controllers that have only 2 presets (I personally made sure that the example of the M.NT68676-2A controller).Here isanother confirmation of this.
By the way, if the text and everything that is written here is poorly absorbed, I recommend watching other videos from langeron.ua. I am not familiar with them and this is not an advertisement (I hope they will not be offended for the link to their video). Just in them you will find a lot of video tutorials throughout the material. BUTherethey can dig and search for firmware not only on the above-mentioned controllers, but also on some others.

Firmware for controllers on Realtek RTD2662 chip
Under the spoiler for the types of controllers there are several references to 6 types of such cards. It also says what is called software for each type. Therefore, I will post the firmware here. Check and take those that fit your fee.

There are few new firmware, but with them you can turn off the blue screen in the absence of a signal. With old firmware it does not always work. In the archive of old firmware there are two folders from the 2011 and 2012. For 2011 (Old Firmwares), even a bit differs in the interface and is a bit trimmed in functions, but those who use them claim that the picture is different from more modern for the better. As in fact - I do not know, but I heard and more than once. The MID Firmware folder has firmware for all imaginable and unthinkable permissions. So without them it would be sad.

The firmware on PCB800196 is two arrays and for some reason they differ in name. It is possible that this is for different versions of the boards, and it is possible that they were created for the same board, simply created at different times, or someone called it that way. In any case, you can safely try - nothing will burn and will not be covered. If you do not go - it means all the same for different boards. Just switch to the right software.

By the way, for the firmware of these controllers, it is not necessary to acquire or do some kind of specialized programmer. The dump of memory is the firmware itself. Those. You can "blow out" from the SPI Flash Memory Circuits (Type 25x40), flash the firmware file itself and install it back.

Link to the controller firmware M.RT2281 / M.RT2281.E5here. It will not be necessary at all often, but if I show this link, it means that someone here had an "experience".

Restore the controller in case of unsuccessful firmware.
If you are as a result of any incorrect actions with firmware (poured the firmware not from that controller, the light blinked during the firmware, the computer failed, etc.) Okirpichili your controller, you will have to remove the SPI Flash memory chip (8-legs chip With the exemplary name 25Q32 or 25Q64) and flash the recovery dump into it. Dump (eng. DUMP) (for those who do not know) - this is the firmware working body, which is prescribed in SPI Flash when you flash the controller with a regular way (via USB). Dump is not a firmware from the above archives, but what is written in SPI Flash as a result of the firmware process. However,hereThe method of firmware firmware ZVST3463 is described in detail without removing the chip (by the way there is no difference, which controller will be restored in this way). So there a man tried to pour not only a dump, and also the firmware binary as it is. As far as it is right and what will be the further results of the work of the controller - unknown. It is possible that if the controller is restored in this way, then you can make a "control" - after restoring to flash once again with a regular way. I would personally have stitched the dump - the benefit here they are available for all controllers. Choose someone who is more convenient - someone uses the programmer for SPI Flash, and someone is more convenient to program through Debug. You can also do this with ARDUINO (herestart and a few posts below). In any case, if the controller is oskarpichen, then incorrect experiments are no longer scary for him - nothing will burn. The main thing in our business is to restore the controller, and in what way it will turn out - the course of events will show.

All recovery dumps have been removed from work boards stitched under ANY matrix (!!!). After flashing and installing the microchip in place, your controller will simply “come to life” and will be stitched for some kind of extraneous resolution. Then, in a regular way, you can upload the firmware you need.

And further. There are several ways to solder a memory chip. I warn you: do not try to unsolder one foot at a time - you will damage both the chip and the tracks. If there are no special means, then at least useby thisorby thisby methods.

thankkenst2009 , he gave a link on a whole cloud of someone's "accumulated experience". There you can also find something. But we must act carefully!
IMPORTANT!!!
There are cases that after uploading the firmware and turning on the controller, the matrix works in the "Pattern" mode (palette) - i.e. alternately enumerates color fields and no shamanism gives a positive result. Not often, but still happens. Most often - this is the lot of matrices Samsung and (possibly) BOE. The reason is a mismatch of the clock frequency (probably !!!). An example of the "recovery" of the matrix LTM200KT10 with a DS controller. d3663lua. a8.2 described in detailhere. For this, a datasheet on the matrix is ​​required. But this is not the main thing - you need to understand what you are doing and what the consequences may be if you use this tool incorrectly. In the above example, the parameter was changed, which is possible and has no relation to the clock pulses and the fact that the matrix has earned is pure chance. But the precedent has been created and the attempt does not threaten with malfunctions. To burn does not burn, but if something goes wrong, you will have to reload the firmware again ...


SECOND PART OF CAPS
read more carefully than the first !!!!!


Post has been editedBoris-leo - Yesterday 22:18
Reason for editing: Note by Skyler 3663



Rep: (563)
Part two.
A forced measure, as in the first post I exceeded the limit. Who knew that the cap would grow so ...
Will be filled as the transfer from the first part.

USEFUL INFORMATION AND VARIOUS TECHNOLOGICAL SILMENTS
This section will accumulate a wide variety of information that will help many find answers to various questions and gain experience from others. Information will be generated in the form of any links, pictures and other things that may push on the best design solutions.
Refinement of the power node matrix in controllers for 3463, 3663 and QT526 is important !!!
This information is important for those who plan to establish with a voiced controller matrix with the supply voltage of the logical part of 3.3V (matrix from laptops, tablets and possibly some monitors). More precisely, even so: the matrix with a supply voltage of 3.3V and a small current consumption is matrices from tablets, netbooks and laptops.
Under the spoiler, the power supply scheme of the formation of the matrix supply voltage in these controllers is shown. So it is when choosing a nutrition of a 3.3V tire restriction + 5V implemented using two successively included diodes:
Attached Image

The scheme is drawn exactly and the errors can not be. As can not be competent such a way down. It can even be called a gross miscalculation scheme engineering, because ... we will not go into the debris of radio engineering, just never done. Chinese engineers can be understood that it was that they were advocated to this - unloading the linear stabilizer AMS1117-33, but it is not easier. Moreover, we have on the forum there are victims from this annoying flap of Chinese engineers with two albeit not very valuable, but trooped matrices in their arms.
I strongly recommend securing my design to everyone who has it is made on a similar matrix. What will take for this: a small DC-DC converter that will be able to "make" + 3.3V. Of course, you can portray this time on the AMS1117-33 linear stabilizer, but the use of the converter has the main advantage - it will not be warm. It must be said that both AMS1117-33 also will not warm much, since the power currents of the matrices usually do not exceed 0,5a, but I repeat, DC-DC is more reliable. This is how it will look like:
Attached Image

I hope the arrows are all clear: remove the diodes and connect the converter module. You only need to connect the earth (there are two of them on the converter and they are connected) and if you take it in the indicated place it is not quite convenient, you can take it where it is more spacious, for example, near the USB connector, there are already 4 large penny weights. The board itself can be glued onto a double-sided adhesive base somewhere close up. And I hope that is clear:IT IS NECESSARY TO EXIST A CONVERTER BATTERY VOLTAGE AT THE OUTPUT + 3.3V TO (!!!) HOW TO CONNECT THE MATRIX . You can directly "in the air" if you do not want to look for any kind of load, but it is better still on the load (a light bulb from a flashlight, a resistor of 100 Ohms and the like).
The photo shows the convertermini 360which is sold in China for about 20 rubles, however, this is the case when you buy 5-10 pieces, one of course will be more expensive. You can buy from us, but it will be even more expensive.
And this is how, for example, ready-made linear stabilizers look like on AMS1117-33:
Attached ImageAttached Image
They cost about the same as mini360. So, rather, this is an idea for those who have this chip in their possession.
I want to note that about this refinement a small discussion has flared up between supporters and opponents. Then everything settled down, butherenew victim ... AhereI showed the simulation process in kind.
As an option - placing AMS1117-33 on the "belly" of the board (3663) fromMarrakota here .

Cables and adapters for connecting matrices
Quite a difficult question: how to connect this or that matrix to the LVDS interface of the controller?
All universal controllers have only one type of interface connector - a double-row male connector (male) with 30 pins (2 * 15) and a distance between them of 2mm.Pinoutit is given in the first part of the cap. I repeat once again: regardless of the brand of the controller, all LVDS connectors are completely identical. If suddenly in any model of the controller there is no pin 4 or 6 - this DOES NOT MEAN ANYTHING, because all three neighboring pins (4,5,6) sit on the mass and the absence of one does not deprive the masses of the neighboring ones.
The range of types of interface connectors for matrices is very extensive - from 20 pins (for relatively old LCD matrices of laptops and monitors) to 60 pins (for some tablet matrices) with inter-spin distances from 0.4 to 1 mm.
ATTENTION!!! For "paranoids": the number of pins on the matrix, ANY SIDE, MUST NOT be CONNECTED with the number of pins on the controller and, all the more, it MUST NOT be EQUAL. These are COMPLETELY DIFFERENT CONNECTORS. Your main task is not to recount contacts, but CONNECT ONLY the NECESSARY interface signals as expected. What exactly - there were as many as two spoilers in the first part. And it will be in the next subsection.
Each accompanying document on the matrix (Datasheet) must indicate the type of mating connector to the interface connector of the matrix.
In any case, it is necessary to find an adapter from the 30-pin controller connector to the matrix connector (more correctly, a cable with the necessary terminal connectors, if we are talking about passive adapters).
Here is an example of how plumes look for most of the matrixes from monitors and TVs, as well as some of the matrixes of no- and laptops of the early years of production:
Attached Image
This is how tails of cables look like under more modern matrixes from laptops:
Attached Image

This is what a 51-pin plume connector looks like for a large number of 32-inch Full HD television matrices with a diagonal of 32 inches:
Attached Image

Matrices for tablets can also be connected to controllers.HereI stopped a little on their description. But due to their rather tangible structural and electrical differences from larger counterparts, slightly different adapters are used for them. Most often, these are transitional boards (therefore, they are more likely adapters, rather than loops), sometimes passive, and quite often they are active. And starting from the presence of the backlight driver circuit and ending with an interface converter.
Here are examples of similar adapters:
Attached Image

Attached Image
In each case, you should know exactly which adapter is needed for a particular matrix. For this and there are datasheets. If the friendship with datasheet is not very - then this topic ...
Recommendations for choosing adapters for purchase.
If we are talking about the cables shown in the first picture, it is easy to see that such an adapter can be sorted out from both sides - rearrange the contacts in the desired positions. Thus, if your matrix has the most common FI-X30 connector (4 in the lower row, 4 pieces to the left), then it is not necessary to search for a specific matrix. Enough to buy the most "filled with wires (in the bottom row, the fourth left,herefor example linkhereIn general, "opt" ...) cable and according to the pinout of the matrix, sort through the wires (there are pictureshere). They are packed there for 2-channel 8-bit LVDS. Therefore, to reduce their number is always possible. We drive in a search for example on Ibea a stringLVDS cableand choose what we need.
In the case of adapters shown in other pictures, everything is a little more complicated. In the search bar, you need to drive in either the connector type or the name of the matrix and look in the proposed list that appears. for examplesuchcable (suitable for many notebook matrices) can be driven into the search tagsI-PEX 20453, 40pin LVDSor in extreme cases, the name of the matrix (especially if it is a rare matrix - the probability of finding an adapter is quite high).
The only thing that is necessary to pay attention is to be paid - this is a matrix with one or another adapter. In the pictures from sellers (if it can be seen), look carefully on the number of blue-white twisted pairs. Under a 6-bit single-channel matrix, there must be four, under 8-bit (also single-channel) - five, and under two-channel matrices - multiply two. If there is extra - this is not a problem, they can be pulled out (or even leave - on the interface for example 6-bit matrices, if it is similar to an 8-bit interface, the excess steam is simply hanging in the air). Worse, when you buy, and the couple does not have enough - then it will be a problem.
Adapters for tablet matrices are a little more difficult to find, because they are usually searched only by tags.LVDS adapteror by the name of the matrix.

ATTENTION!!! A very important point.
The starting point of the contacts on the connector that is inserted into the controller is necessarily marked with paint (no matter what color). The main thing - it shows the angle where the FIRST contact is:

Attached Image

Do not look at the triangle melted on the connector case - it is usually opposite the SECOND pin. Even as a sign of starting point on the connector - red power wires (which, as you should already know, are inserted into 1-2-3 pins). There is information that came across someone connectors with black power wires. This is extremely rare, but if anyone ever catches such a thing, be sure to ring them on the LVDS matrix connector and verify the correctness on the datasheet.

As I said above (under the spoiler about the controllers), plugs for connecting notebook matrices often have a tap to the backlight control connector (if the cable is of this configuration and under the corresponding matrix). In it, the output of the backlight brightness control is usually connected to the backlight output. And if you plan to connect the matrix to the controller V29, V39, V56 or V59, you will have to separate this wire and make a separate contact in the correct pin connector.
And finally, about rare special adapters.
Above the first spoiler mentioned matrices from the RSDS interface. The interface is quite rare, but it happens that when displays some monitor, it is such a surprise. They come across 17, 19, 22 inches. This interface can be bolded to call "Loading", since in addition to the native Main of the monitor, it will not be possible to connect it. However, the Chinese have succeeded here. They make special adapters for these purposes. There are options for these adapters for RSDS interfaces of any "pinness" that exist in nature. They look like this:
Attached Image

I used it only once. I had on my hands a monitor and a TV of one Acer company 22 inches 1680 * 1050 (I won’t tell the models anymore) and the monitor was a matrix donor. Here it turned out to be just an unexpected in the form of a matrix A220Z1-H01. I had to buy such an adapter. To my surprise, the matrix with him, installed in the TV and connected to his LVDS, earned immediately and without any tambourines.
To connect to universal controllers 4-channel 10-bit 120Hz television matrix in China are also sold ready-made adapters. They are an active converter of a 2-channel 8-bit LVDS signal into a 4-channel 10-bit LVDS signal with an “understandable” such matrix structure. Here is one of the options for how a similar adapter looks like:
Attached Image

BUTherehis description (many thanksluckylamer ).
Personally, I have never tried such an adapter, but there are positive examples of the implementation of projects with it by the forum users (see the spoiler of finished projects).
To buy on Taobao, the first adapter can be searching either by tag LVDS 转 RSDS, or by the name of the matrix, and the second by tag 120Hz 转接板. In the picture, two connections towards T-CON are written as 45 and 55 PIN - this is a typo, in T-CON connectors 51 and 41. And immediately I want to warn that the prices for these two adapters are very sensitive "bite" - the first stand in the area $ 15, and the second - in the area of ​​$ 35. But how to look for these adapters to Aliexpress or E-Bay - I am not ready to say. For example, we give one of the options for the second adapter to Ali SPress. That's just a search tag ... Take a look
Attached Image

According to the forumVic2604 It was such an adapter that he wound up without any problems at all. The main thing in this case - he agreed with the seller on the selection of loops for a specific matrix.
There is another type of adapters that are designed to connect the eDP matrix to the usual LVDS interface. They look like this:
Attached Image

In the picture you can read an approximate list of matrices with eDP interface that can be engraved with the help of such an adapter. This is done a little difficult (the choice of a variety of jumpers on it), but nevertheless its existence is an irrefutable fact. Find this is only possible in China, a tag for searching LVDS 转 eDP 万能 驱动 板 or LVDS 转 EDP 转接 板. The cost of such an adapter in a circle with delivery of about 15 dollars.
Since this topic was written for quite a long time, during its existence there was a need for another pretty peculiar adapter - from a simple interface (input) Full HD LVDS 2CH 8 BIT in the output interface V-BY-one, because to raise such matrices of another way in There is no longer a foreseeable space (well, in addition to the search option, the desira from bats with such matrices). Thanks to our Chinese friends, this adapter also appeared on sale. I cite a screen, not a link. To search for a series, try to find the method of variations in the LVDS V-BY-One phrases.
Attached Image

I will separately dwell on one more kind of loops - a loop for connecting the matrixes with LVDS connectors on modern motherboards. Here the situation is quite deplorable - a complex connector is installed on the motherboards (namely, modern ones, starting with atoms 2800) and finding a suitable “tail” for it is quite difficult. I gathered all the informationhere.
In conclusion of this section, I would like to give a link to one busy store. I understand that this is not entirely correct and maybe even not quite acceptable. But since the adapter is a very specific thing and find the right thing is not a simple task. Even on such a large trading platform as Aliexpress find the right and very difficult (first of all, due to the lack of proper description from the sellers), but this store contains a very impressive collection of almost all occasions. Perhaps simple loops you can find somewhere and cheaper, but find many adapters almost no place. And most importantly, the seller is very well versed in any matter and can advise in the connection of any matrix and offer everything it is necessary for this.Here ishe. How long it will exist is unknown, but the makings of a long existence seems to be there.
BUTherea reference to a major Chinese manufacturer of the overwhelming amount of all the above iron. Perhaps it will be useful to clarify any technical characteristics. In the left column, select the subject of adapters and see what is in nature.

LED driver. Simplified theory about the work of a difficult node
Consider the LED as a light source. First of all, the LED is a semiconductor. And this means that it cannot be considered as an ideal active peer - its parameters "float" from temperature. If you attach some stable voltage to it, immediately after switching on (while it is cold) the light stream will be lower than the one that will be after the time (when the LED warms it). This is always happening, regardless of the type of LED and its manufacturer. To this not happened, the LED is powered by a current. I will not climb the debris, but (generalizable) current flowing through it and determines the brightness of the luminescence, regardless of the temperature of the LED crystal. Accordingly, if the current stabilizes - the light stream is stabilized.
A few words about the concept of current stabilization. The whole earth is spinning around the law of Ohm. The joke of course, but the formula i = u / r is the fundamental. There is some kind of stable load R. How to change the current i, which flows through it? Of course, the voltage change u! LED - the load is not quite stable, not quite perfect and completely non-linear. But no matter how he capricized and did not build faces, he still did not go away from the law of Oma - the current through the LED is also regulated by changing the voltage. The case is "small" - control this current. For this, there are LED drivers. If we do not say a "driver", but "inverter" - we will also not be mistaken, because it is possible for a circuitless difference and do not feel.
So from the previous paragraph, we found out the most important thing: LED driver is a current stabilizer via LEDs. ALL!!! It also gives the voltage, but its goal is to issue a stable current, and the voltage is already a secondary value and not even stable. It will be exactly as much as it falls on the LEDs with a stable flowing current at a particular point in time. When you turn on, the voltage drop may be, for example, 56V, and after two or three minutes - 52V. I hope it explained clearly.
Now "about sad". LED driver is a rather complicated device in technical terms. Its possibilities are not limited to all and completely dependent on the technical requirements for the backlight. What is meant here. The fact is that the driver itself is powered by some particular power supply voltage. In small structures (up to 24-27 inches), this is usually 12 or 19V, in large - from 24 and sometimes from 48V. But the design of the backlit matrices can have a variety of configurations and power consumption. Accordingly, most often (especially in the matrices of large diagonals) the driver is done unique - i.e. Only under the specific backlight. A small sample shake of the brain: 24V supply voltage. At one matrix, the drop voltage on the backlight is 12V, and the other is 50V. What does it suggest? And the fact that the drivers should already have different principles of work. And it really takes place: the first driver is called a "down" - step-down or buck, and the second "boost" is STEP-UP or BOOST. At the same time, do not forget that the priority task is to issue a stable current in the load. So the driver is already a kind of compromise between several tasks: to issue a stable current, do not forget how voltage will participate in the formation of this current and take into account, from which source the driver feeds on.
Lowing drivers are rare enough, since the drop on the backlight 9-11V is found only in matrices from tablets and the like. They are calculated on a weak (about 1-2WT) illumination power, circuitrynically they are very simple - usually they are made on one specialized chip in the SOT23-6 case with minimal strapping, and often even present in the finished form on controllers boards (for example, PCB800099 and the like ).
It is very different about the uprising drivers. To understand the principle of its construction, I will better give a simplified structural scheme
Attached Image

For a better understanding, I divided the driver into two functional parts: at the top of the voltage multiplier control unit, at the bottom of the current and control part. The voltage multiplier consists of a throttle, Schottky diode, switching key on the MOSFET transistor and a smoothing capacitor. The multiplier just determines which maximum voltage will be able to give the entire driver on the load (LEDs). Out - the release of the chip, which manages the multiplier. At this output there is a sequence of pulses with a frequency of several hundred kilohertz to units of megahertz (depending on the microcircuit applied). OVP and OLP circuits - voltage and current protection, respectively. OVP deciphered asO ver V OLTAGE P Rotection, OLP - O ver L oad P Rotection (sometimes, and perhaps even more often occurs the name OCP - O ver C Urrent P Rotection). The lower part of the chip is responsible for switching and stabilization of the current in the load. The circuit of the LEDs is a measuring resistor with which the value of the flowing current is removed, compared in the internal comparator with some kind of exemplary voltage UFB, and, depending on the deviation of the results of comparison, the diet of the immuls entering the navation of the key transistor multiplier. * Source - the ratio of the pulse repetition period to the duration of the pulses themselves. Thus (change in pulse duration), the output voltage of the multiplier is adjusted and therefore the current flowing through the LEDs. It should be noted that the voltage adjustment in such a way is ultimately far from linear and works efficiently only in a fairly narrow range. Once again, I repeat - the scheme is highly simplified, since there are many different schemes and principles on which the microcircuits of drivers of different manufacturers work, but the essence of the same. And now to the most important thing: to the abilities of such a scheme. It is clear that it is difficult to deceive physics, so any action on multiplying any physical quantity cannot be ideal, as it is inextricably linked with an efficiency, which is never known to one. This scheme is considered "double" - i.e. Multipates the input voltage by 2 times. The ability of the multiplier is not limitless and the maximum current is dictated by many factors: the voltage drops on the open vein, the inductance of the choke, the voltage drop in the throttle at the operating frequency, etc. At idle (without load), the output voltage can also be a fivefold input, but when current appears in the load, it drops sharply. Those. It is possible to hope for the greatest effect of such a multiplier when the load consumes such a power at which the voltage drop on it is within the double feeder (just on the "narrow" section of the conversion efficiency, which I said two sentences above). But since the production of drivers use elements that have a solid supply for the current (for example, MOSFET with the maximum allowable current to dozen amps, Schottky diodes with a current from 3a and above), and often such a driver works on highlighting with consumption 100-600m, then quite Really get on the load (LED line) a voltage drop is not only a 2-fold nutrient, but also 3- and even 3.5 times. I repeat - it all depends on the maximum load for this case. The less load - the higher the multiplication multiplication can be obtained. What I pay attention to this. Often on the Sale of Drivers on the Aliexpress website you can see the following

Note that it is written according to the characteristics. Many people think that by installing such a driver and drinking it from 12V (after all, it is in the agreed range of 10.8 ... 24V), you can light up the backlight with a drop in 60V (it is also in the agreed range of 15 ... 80V) . In fact, everything is completely wrong. And if the current on the LEDs should be within 0.4 ... 0.8a, then from 12V this driver will simply not light up - the current multiplier restricts (and if such a restriction is not laid or done "in Chinese" and takes the key to overheating). Cause - I said above. Exit from the position is to increase the driver's supply voltage at least until 19-20V.
Let's summarize the above: Two-time Boost Driver Depending on the load power, it is capable of issuing a voltage within 2-3 times from the input. At the same time, 3-fold multiplication is possible as a rule with a small load capacity. In case the load is significant, it is best to navigate at 2 ... 2.5x multiplication. For example, the driver, which is depicted in the picture, with diet from 12V easily copes with a highlight of 200mA with a drop of 32-40V. But it is worth connecting the backlight of 400-450m with the same drop, for 5 minutes the key transistor is heated so that it is impossible to touch it. Further,Nothing change , We connect the driver to the 19B adapter - for several hours of work, it continues to remain cold in the present sense of the word.
For multiplication of voltage 4 times, the driver is made with two multipliers (you can permanently for an aliexpress for example CA-288). Those. One cascade multiplies on two, the second is another two. By the way, this scheme is capable of multiplying up to 6 times, but again, with a correction for a given power. And if you need to light the backlight with a drop in the 70-80V area, then it is better to connect a 4-fold boost driver to 24V meter (as a last resort of 19B), but not 12.
By the way, there are boost drivers in the micro execution for some types of tablet matrices, which requires 100-160 mA with a drop of 18-21V. As already clearly from the given data, the power of such a backlight of the order of 2-3 W and with this completely copier with the chips performed by SOT23-6 with the built-in key. These are infrequently required, but nevertheless they exist.
Finally, once again I will return to the topic of lower drivers. I have already told about completely low, and the most powerful essentially is one single option on the DF6111 chip, and the most "powerful" load for it is a strip to replace the lamp light on LED. I told everything about himhereAnd there is nothing more to add.

Types of connectors that are used with controllers
I cite types of "mom" (on cable) - i.e. mating connector to controllers.
So, in our trading networks they are called MU-X F, where X is the number of contacts. Those. 6-pin mother is called MU-6F, 4-pin is called MU-4F.
The Chinese Internet stores data terminals are called Micro JST 2,0 PH-X p or PH2.0- X p, where X is also the number of contacts. But best of all they are searched for by the tag " 2.0 PH n "where n is the same
number of contacts. In the “Dip and Chip” electronic components stores, this outlet is called “Socket for 2.0mm PHR-x cable”, where x is the same number of contacts.
The LVDS mating connector is much less common (if only because all the same demand is more for cables than for bare connectors), but for example, in ours, they are seen in the "brown bear" asBLD2-30, but there is one more "but" - this is only the connector body, how about the contacts themselves - find out for yourself.
As one of the options for replacing the contact pitch (2mm), the connector from the IDE cable for notebook HDDs is suitable.
And yet, quite often in monitors or televisions, the LVDS cable terminates in a suitable connector too. It may look quite unlike BLD2-30 (it may be of a different color, with some plastic ledges, etc.), but if the pitch of the pins is the same (2mm), then why refuse to use it? After all, one end of the cord has already been cut under the matrix - all that remains is to sort out the second one and no need to order in China and wait a month. The main thing is to ring correctly and, if necessary, to sort out.
And it’s not at all necessary to look for exactly 30 pins. The matrices are different: for a single-channel 6-bit connector is enough for 16 pins (2 rows of 8), and for 8-bit - 18-20 pins.
Here is the table, how many pins are needed for interfaces of different frequencies and channels:
Attached Image

HereI clearly told how to reuse the LVDS connector - i.e. if you suddenly need to move to other wires, etc. And this does not necessarily apply to LVDS, but in the same way any crimp connectors can be reset.

mini-LVDS - what the ... and how to deal with it
I think it will not be superfluous to focus attention on one more “variation” of the LVDS interface - mini-LVDS. This "beast" is found in the vast majority of matrices and there is no standardization of it for pinout. And of course there is no guarantee in matching the pinouts not only between different manufacturers, but even from the same manufacturer in different model series of matrices. What is it, let's try to figure it out ...
So, all matrices necessarily have a timing controller (T-CON). Its purpose is to decrypt LVDS signals and transfer to the glass of the matrix of all necessary for its operation: signals for the formation of the image itself and service signals. In the television matrices of the early years, this node had a separate execution and was removable (as a single board on the connectors). There were not rarely TVs in which T-Con as a separate node was generally absent - it was part of the Main Board board. In more modern T-CON matrices, it is increasingly being made non-removable - it is Raskidan on fees, which tightly through flexible loops (called COF loops) are glued to the glass. A clear case - we can not talk about this and talk yet about the first.
If you carefully consider T-CON, it is clear that the LVDS signal is applied to its input, and the loops are connected to the output connectors (they are also removable) to the matrix glass slaves. According to these plumes and are transmitted from T-CON signals with the MINI-LVDS interface. It contains image forming signals, gamma correction, power and service signals. And at least mini-lvds and sounds like, but with the entrance LVDS interface he has almost nothing in common.
All of the above information is only for understanding, which is generally about. The technical details are important for those who have the task to replace the defective marine of the TV or simply profite the TV and connect to the matrix or the universal controller, or any modern Main with all the "beams". And the further algorithm of action will already be folded from some important factors, alleged opportunities and situations. If the matrix does not have the T-CON card in general - it is quite possible (most often this is how) that the glass of this matrix could stand in other matrices in which T-Con was present as a separate node. For example, the LG-Philips matrix of one line could be in several versions: with a 4-channel 10-bit LVDS interface, with a 2-channel 8/10-bit LVDS interface and mini-lvds interface. What is meant by the words "one line" - the fact that in all three types of simultaneously produced matrices used the same (or very close to the functional) glass, only one or another T-con (or was absent in cases where it Placed on the lane). And we need to find and if such exists in nature - to purchase a suitable T-CON board, connect it to mini-lvds the glass interface and thereby get instead of an "exotic" conventional matrix with LVDS input. There are other situations when after the death of the Mineland at the disposal of the owner remains a kind of "designer" - a TV with a very good matrix and PSU. It is only required to find a Mineband or its replacement. But quite often this is a 4-channel LVDS matrix. To connect the same universal controller (which at its output has only 2 channels), you can go two different ways to: Buy LVDS converter (about which was discussed under the spoiler "loops and adapters for connecting matrices"), or as in the previous one The case instead of the 4-channel T-Con to find a 2-channel (again, if there is in nature). At the same time, the second path would be preferable (and cheaper). Therefore, it is better to look for - look at the setting. The main thing is not to be mistaken in the choice.
A pair of nuances about timing controllers:
1. In the matrices of one manufacturer of different diagonals, one and the same T-Con can stand. Those. On the table, the TKON can be written for example 47 inches, and this board can stand in matrices from 32 to 55 inches. It should not strain anyone. I specifically did this statistician, but it's easy to make sure that LG, Sharp, Auo matrices.
2. In the names of the LG-P matrices, everything is quite transparent and understandable - first the digit is diagonally, and then three letters:
- first: W represents the execution with fluorescent illumination, D or E - LED where D - direct LED, E - edge LED
- second: U stands for full HD resolution, X is HD Ready
- Third: N, Y, E, G, D, S, F, H. L Just can define a ruler, a series, a type of interface, and further rendered suffixes (for example SB A1, PE F1, etc.) backlight. Moreover, the matrices with a luminescent illumination list of suffixes are small - usually nothing more than SA, SB, SC. This is connected with a small choice of design versions of lamps. LED - suffixes are much larger, because the LED backlight can be both self-use as part of the matrix and the finished driver and separately withded LEDs with various schemes of their association. Immediately I will say that this is just the result of observations, and not official information from the factory. Plus still has the value of the production period of certain matrices. But in the overwhelming majority, all the same can be shipped by datasheets on matrices WUN, WUY, WUF, EUH, EUF, etc. And make a conclusion for yourself, from what to try to look for T-CON fee.
How to search. Whether in the search engine the name of the matrix and the word "T-CON". There will be a lot of information about the sale of TKons from this matrix - there and will find the exact name of the board. Then on the Internet, it is enough to find the pictures of a large permission for certain TKON cards, check with the LVDS interface type (remind you that the universal controller needs 8 bit 2-channel Full HD (this is usually one connector 51 PIN). Then you need to look at the organization MINI-LVDS outputs, first of all the number of output connectors and the number of their pins. It is clear that the glass 2 * 60 PIN can not pick up the TKON with an output of 2 * 50 IDUs and vice versa. After the choice of potential applicants, you need to look at the table TKON. In Mini-LVDS connectors. At least start with the mass conclusions, gamma, the number of pairs of LVDS signals (as part of Mini LVDS!) - They can be seen by parallel with steaming conductor. Often on the board you can see the signed steps of control points from the tracks of the connectors. In general The process is nothing more than a quest and 100% guarantees, though there is no, but there is still a chance to find everything. By the way, there is another trick with LGP matrices: all T-CON boards have the name of the model of the type 6870C -0xxx. You can get as a basis in the search for the last number on T-CON (which I signed as "XXX") and try to add or take away a unit or a two - quite often in these T-CON glasses, which were developed simultaneously for different interfaces, had "neighboring" Factory numbering. The matrices of other manufacturers will not pass such a focus, since there is no clear numbering like LG - it is necessary to look for a similar name (maybe the difference in some letters or versions - everything is necessary to look more intently). Try.
As information about the miraculous “engraftment” of this kind is confirmed, I will post more accurate names of what I crossed with.
So far, absolutely accurate and confirmed information (from me personally):
- Philips 32PFL3606 MINI LVDS LC320WUY (SC) (SC) (A1) Matrix (SC) (A1) without T-CON boot. Side T-CON 6870C-0310C LC420WUN-SCA1. 6870c-0310 and 6870c-0318 are also suitable with any letters at the end.
- Philips 55PFL6008 TV LC550EUF (PF) matrix (F1), native T-CON 6870C-0450A (51 + 41 PIN, 4 channels 10 bits) Replaced with 6870s-0451A (51pin, 2 channel 8 bits) from LC420EUE matrix (FF) (F1). By the way, this is exactly the case of what I said above is - the latest boards are different per unit. Yes, and on the T-CON 6870S-0451A board is written more LC470EUN-PFF1 - as you see the size of the diagonal does not matter here.
- PHILIPS 42PFL6057 TV (6007, 6097,6877) Matrix LC420EUF_FEP1 native TCON 6870C-0402C (51 + 41 PIN, 4 channel 8/10 bits). Replaced with T-CON 6870C-0401B (51pin, 2 channels 8 bits) from the LC420EUE_SEF1 matrix (the same is also in LC370EUE_SEM1). Thank you_LennY_ .
- SAMSUNG LE37C650 TV Matrix AUO T370HW03-VH. Native T-CON T315HW04_V3 CTRL_BD 31T09-C0K (82 PIN 4 Channel 8 bits). Chinese adapters under such a bit rate do not exist - respectively, no other options for its use except with the native lane. Changes on T-con T315HW04_v0 Ctrl_BD 31T09-C0G (from the T315HW04-V4 matrix) but with a small refinement: instead of resistors R922 and R923 (by 31.5), 5.1C (R922) and 6,800 (R923) are set. After that, the matrix becomes 51 pins, 2 channels, 8 bits. Thank youNAILKA82 (Although it, on my initiative, he went to such an adventure).
If there are positive results from the forums - I will add ...
And of course we should not forget that after such happy cases of "healing", the matrix gets out one underwater stone - T-CON fees are not often able to turn the image by 180 degrees (especially LG-P). Here immediately focus on the controller (or Mainbord), which "knows" to turn the image.
Well, finally, I remind you: everything above, refers to LVDS matrices. I intentionally do not affect modern EPI or V-BY-one interfaces here, since this is a completely different and more complex topic ...

Cooling of the main controller chip Z.VST.3463A and D3663LUA

Such can still be obtained from old routers or AT motherboards.
Recommendation. As a rule, the fantasy of many "self-relocked" further than an enlarged radiator and a small carlsson planted on it, which blows into this radiator does not go. However, this is not a completely efficient method of anticipation. There is another way to cool the main chip (besides much more efficient): the fan is not put on the radiator of the chip, but on the rear cover of the case exactly opposite this radiator. What is achieved by this: the requirements for the diameter of the fan are blurred - after all, it is really not to be praised on the fee and plus (usually) the larger the diameter of the cooler - the smaller its turnover (respectively - it works quische). What the fan needs to be put so that it "pulled out" air from the radiator. Thus, cooling becomes much more efficient and (according to my personal test) a fairly regular controller radiator. But there is one condition - the fan must be as close as possible to the radiator. If the back cover does not structurally close the fan to the radiator, you can put the similarity of the "pipe" like this, as many could observe on the example of computer enclosures (where the pipe is standing on the side cover, which when the cover is installed close to the processor fan). Making such an air duct is quite easy to make an unnecessary blister pack from anything.
And finally, the "bike" from me.
I have a column hanging for hot water at home. "Fashionable", with electronics and temperature poise meter. When there is a temperature of 45 degrees, the feeling that you can scream hands. If you put 50 - just tin. What is me ... For a silicon crystal, a normal operating temperature reaches 60-70 degrees. So draw conclusions. No one guaranteed the room temperature of the chip - it's rather for your calm. It is very possible that natural convection (if it is present in your housing) is quite enough.

All about consoles
At first glance, it seems that the controllers are so "universal" that even the consoles are the same, but this is not quite the case.

This question caused a whole storm in the discussions until all versions of the remote controls were revealed. It turned out that the question is very delicate and serious.

Universal Controller Keyboard Board
The board is a set of 7 buttons and a two-color LED. The remote “eye” of the remote control also fits to the board - it is on a separate board. It's about the purchase of a set of Chinese. However, the board is so simple that everything can be done by yourself. How the buttons for the V56, V59 controllers function - you can see in my projecthereand how they follow in the controller ZVST3463 - ibid, according tothe tableDingKe type.
You can stretch the keyboard buttons with a bundle of 6 or 8 wires (straight from the controller connector), and if you don’t want to pull such a bundle, you can get by with just two. Then you just have to make the buttons bysuchscheme (scheme from the same project).
In the latest modern D3663LUA and Qt526 controllers, the keyboard buttons are assigned in a completely different way. The order of the buttons is shown.here (project winsasha ). About the same warned here Secondshadow . However, for a DS3663 controller, the keyboard must be assembled using the same link above to the scheme (while the assignment of the buttons themselves is different), and for QT526 the buttons are even assembled according to a different scheme:
Attached Image

I do not know for what purpose 8 buttons were originally conceived. With high probability, the Options button will not work at all. On the right (in the picture) I changed the scheme for 7 buttons.
Implementation scheme of buttons for two-wire controller is shown for RR52C.81Ahere.
There is another "theme" - in the fresh controllers, the function of reassigning buttons is increasingly beginning to appear in the service menu. I personally have not tried it, but I know for sure what is in QT526 and in RR52C.81A.Tyk. TSUMV56RUU-Z1 is also mentioned there. But in any case, with the initial firmware, the order of the buttons will be as stated above. And if you reassigned as you like and conceived to reflash with some other firmware, you will have to restore everything again.
Display LEDs are connected each to its connector pin: Red - to LED_R, green - to LED_G. You can apply both a three-way two-color LED and two separate. The main thing is to contact LED_R and LED_G connector, the anodes (!!!) of the LEDs are connected, and the cathode (in three-way) or cathodes (in individual) - for mass. The inscription R and G does not mean that it is necessary to apply only red and green colors - yes, even though. If the redesigned device has LEDs (usually there are white) backlighting the brand logo (available at many TVs, especially recently began to apply widely on Chinese "brands") - I would recommend connecting them to contact "LED_G" - will be super. ..
Sometimes in the finished design (which serves as a donor for homemade) there is only one LED and the second one is not just difficult, and sometimes it is impossible. For example, when the LED in the SMD form factor and next to do not stick anything, but also there are also no free contacts in the slip connector. Then it is possible using two diodes "collect" LED_R and LED_G lines in one (diodes in direct turning on each line are connected by cathodes to one point) and this single line is fed to one LED. Then it will work in mode close to a staffable for the recoverable apparatus, i.e. In sleep mode, it glows, in the work - glows, and when the team arrives from the console - flashes. However, as practice has shown, even one "red" LED and no associations in the line. INby thisI applied only one LED to my project, connected it to the "red" contacts and still do not feel inconvenience - it alone suffices. It glows in sleep mode, when the TV is on, it does not glow and blinks when commanded from the console. As you can see, there is no need for a second color at all.
As for the photo receiver eye, download the manual to any controller and there you will see the simplest scheme for assembly. By the way, in all TVs the “native” photo-eye is assembled according to the exact same scheme, well, maybe there are some minor differences, but it connects the same way. The type of photodetector (it is not listed there) is VS1836B (the real "branded" eye from Vishay is called TSOP1836 or TSOP1838). Contacts on the universal controller connector, to which the eye is connected, are also indicated in all manuals.
By the way, one more thing (for those who are not “in the tank” at all): there are only two “masses” on this connector and if you pull the buttons separately (and they “work” with respect to the mass), the LEDs are separate and the peephole is separate then one more mass contact is not enough. It is only necessary to "branch out" any of the existing "masses" with two wires.

How to get sound from HDMI using a simple "add-ons"
This question may not be dictated by the theme itself, but has a broader ground for action. But I think it is quite appropriate here. So our task is to expand the functionality of "silent" or monitor the controller. In China, there are a lot of things, but I just tell you that personally I have just experienced. Well and, accordingly, I think nobody wants to inflate the budget problem, and as much as possible of his "shrink".
Option №1. Take a simple splitter HDMI. Do not switch or switch, namely a blunt splitter. It costs around 100 rubles. And to take it even adapter HDMI to VGA with audio output MUST. It costs 150 to 250 rubles. I was the second in the presence of. Connecting primitive to ugliness:

On transactions do not pay attention - I'm Samodelkin. And so I learned a control wire with the active HDMI (for their needs). The adapter is powered from the HDMI cable, the sound of shooting with 3.5 mm jack. The sound is excellent, without hissing or wheezing. Adapter for 150 rubles looks even more attractive:

This I do not have - so its functionality can not say anything. There are "boxes" with a HDMI to AV function - with HDMI input and output of the three "tulips". But there is this box is much more expensive.

Variant №2. Take the entrance HDMI adapter. Those. it has an HDMI input, HDMI output and sound branch to jack 3.5 mm. For me personally, there is just such a - so that I report only to him:

What to say ... he also works. It is about 350-450 rubles. However (!!!) Compared to the previous option, it will still need an HDMI cable for connecting. As if the thing is not expensive, but nevertheless. The pictures you can see that this box has a mini-usb input to power, but it works quite confidently and without meals - it takes from the HDMI line and grabs it. The sound is the same as in the previous example. If anyone needs a better sound option - there are boxes with HDMI passage and sound branch on coaxial, SPDIF and Jack. They are more expensive - under 700 rubles. And, believe me, they also work well, I put such a friend to connect good acoustics.

But whatever the "honey" neither was this solution, there is a spoon of tar in it: the sound removed from these jacket, the total image is ahead of the second. I compared the connected TV and computer columns simultaneously - it turns out not even as a small echo, but a sufficiently distinguishable repetition. So there is nothing perfect. Although, depending on which content is viewed. Foreign films with translation, music, porn: D, cartoons, and many Soviet films do not suffer from this. Perfectionist will notice this on some live air with a close-up.
In China sold more and more "civilized" box for this purpose. Possible (!!!) that they have taken into account this is a misunderstanding. And they are from 1200 and higher, up to 4000 rubles. But where is the guarantee that he gave the dray amount we do not receive the same as for 300 rubles? That's it ... In the meantime, study the subject adjustable audio delay. They say everything can be done on a single chip from Holtek, vosminozhka with minimal strapping. If that dig - add ...
Yes, I hasten to announce yet another hypothesis: I confess, I have experienced on your Philips TV, and even smart. Bearing in mind what is the brake, there is an assumption that the processing of HDMI video monitor is faster than the TVs, and maybe a difference with the sound ahead of the monitor just will not.

How to increase the number of HDMI inputs using a simple "appendage"
Sometimes there is a need for more HDMI inputs than the only one on the controller. In this case, I can simply recommend (because I myself used to twist it in my hands and used it) to automatically switch the HDMI inputs. This plan:
Attached Image

I deliberately provided a picture, not a link, because the product can end, but you can always find it on Alibaba by the picture and the "3 to 1 HDMI" tag.
What is "automatic": the switch itself switches to the input where the HDMI signal appears. Moreover, if at some input signal is already present and the switch is on on it, then when the signal appears at another input, the switch will switch to the newly appeared signal. After it is turned off, the switch is returned to the previous entrance. A switch either feeds or from the source + 5B (for example, from the free USB output, from the adapter to charge any modern smartphone), or from any HDMI input (those cords that are inserted into sources HDMI).

Radio elements on controller boards and their replacement
Under this spoiler, I will add proven options for replacing radio components on controller boards as I am.
1. About the audio chip CS37AD2AB and its replacement informationhere.
BUThereone more experience fussing with this frail microcircuit. I think now the controller's MIND will only become more reliable and certainly not worse.
2. Chip DC-DC down converter. Many boards are rated for 1.2 and 1.8 volts. Small, 5-legged, in the case of SOT23-5. The designation AAAA, AAAAB, AS11D is found. Known replacementMT3410L, SY8008or AUR9703tyk.
3. MOSFET key, which is installed on almost all controllers as a matrix power key and a secondary power key. Mostly found with WSA6L, WSA6S. The correct name is LCS68P03. According to the datasheet, the designation is WSA, and the remaining digits are the date, batch, etc.
Attached fileLCS68P03-2.pdf(504.82 KB)
It changes to absolutely any p-channel MOSFET key with similar parameters. Of the names (accurately known), AO3401 was checked (the cost per unit size was 6-7 rubles), of the markings, B052 was checked (unknown name). What else I learn - I will add.
4. Integrated circuit DC-DC converter 12B-5B, octopus (SOP8), denoted 5 DABAD type letters, DAAAB and in this way. On AE is sold under the names L6562A, L6562AD, which is clearly not true. Wherein "draw"It is clear what you need. Therefore, 100% warranty is difficult to give. Rather, do not give it at all. I will offer my own version of the replacement of this chip, which is certainly easier to get - MP1583. This option is suitable for use with a small power matrices controller. If the controller is supposed to use the controller With a 12-volt matrix, then you can apply MP1410 (2-ampere transducer) or MP1483 (3-amp). It is also possible to use TPS54329E. But in I proposed variants of the output divider, unfortunately may differ from the one that is installed on the board. Universal controller. The diagram of the DC-DC converter is:
Attached Image
So the output voltage (and in our case it is 5V) is given by resistors R1 and R2. But each chip they must be "their own". In datasheets they write how to choose them. Therefore, all the above, the listed options for replacing alas are involved in the selection of these two resistors. But in a hopeless situation and this is a way out. Another fresh information: In the fresh part of 3663, this chip is called GP 0CD0R or something like that.HereReplace information on FR9888. So quite an effective option.
The easiest way to get out of the situation created without special dyghe and complex searches - To pull the burner chip and instead to pick up the DC-DC converter module. This can be for example mentioned under the spoiler about the passing of the power of the matrix 360mini. Simply before it is connected It is necessary to power it from 12V and put on its output + 5V. And it is not at all necessary to pay the wiring from it exactly to the location of the chips of the chips: 12V input can be taken from the power connector, the output from the module to connect to any throttle output (from the cutting of the chip) and the mass - at any convenient place. And the module itself can be positioned on any cooled surface, which will be near (for example, on the back of the matrix) of course applying the necessary measures from the closure of the supply points for mass. If a matrix is ​​assumed with a long power consumption current (for example, the chimei matrix with diagonals from 26 inches and more and 5V), a more powerful module should be applied, for example LM2596, which is designed for load 3-4a. By the way, even with a serviceable microcircuit on the controller board when connected to such matrices, I would recommend using such a module, drinking it from the connector 12V and connecting it to any of the three connected pins of the Power selection of the matrix, and the regular jumper is deleted at all. As for the matrices with 12V nutrition - they do not apply any criteria to the choice of the module, because this module in this case is powered by the controller itself, and not the matrix.
And finally.Hereone good man laid Changhong TV circuit in the MCU MSD3663. It is clear that it is not 100% D3663LUA controller scheme, but a lot of moments where you can learn - MCU strap, tuner, power supply circuit core, keys and stabilizers. Pretty much the same. So the name of radio can be found there.

How to flip an image 180 degrees
Often it is necessary to turn the image upside down. This is due to both the design of enclosures and the design of the dies.
We will not go into the reasons that lead to this procedure. In short, you need to enter the service menu, find the General Settings section there, and the Mirror item in it (yes, yes, for some reason, the Chinese dubbed it exactly as a “mirror” rather than a “turn” (rotate)) and change the value.

How to align (adjust) the volume levels in different modes of the controller
Immediately I warn you - this "defect" was noticed in the operation of the ZVST3463 controller. It is quite possible that such an adjustment may also be required in the 3663 controller.
So why it took. It was found that the sound volume levels (on the volume scale on the screen) in the digital television reception mode are quite significantly different from those in the receiving mode of analog TV. The service menu has a nonlinear item, which has sub-clause VOLUME CURVES. VOLUME CURVES literally means "volume curves", in other words, the loudness level of the volume of the key points. Key points 12. Those. The schedule is divided into 12 intervals, and the numbers indicated opposite each key point is the maximum volume level at the end of this (!!!) interval. Thus, the maximum volume values ​​are set for each interval and from these pieces there is a whole schedule from full silence to a maximum. Obviously, the initial volume level for some particular interval is equal to the final volume level for the previous interval. Volume curves are described separately for analog and digital TV. An analog or digit is selected right in the first line after entering the VOLUME CURVES arrow to the right or left.
You can do this: you need to look at and record the level values ​​for each key point, for example, for analog TV, go to the sub-item for digital TV and change the values ​​for the corresponding key points to the same ones as in analog TV. Or vice versa - transfer the values ​​of digital TV levels to analog levels. Then the volume will be the same here and there.
However, I analyzed the values ​​of the levels for the key points and tried to interpolate the total curves at least somehow (taken from the XIANUAN 1366 * 768 firmware). I must say that I could not explain what I saw:
Attached Image

Therefore, I slightly analyzed the “steepness” of the increase in volume and corrected the graphical representation of the curve and selected the most favorable values ​​for each key point after interpolating the resulting graph. I got the following values:
80, 490, 675, 750, 810, 865, 900, 920, 950, 980, 990, 1000. In general, it turned out well and quite smoothly. True, there is a small trick: you first need to install these values ​​for analog TV and only then go to the installation of the same values ​​for digital. Because somewhere in the depths of the chicken brains of the controller, these values ​​are intersecting and initially high values ​​on an analog curve do not allow to set my values ​​in the figure - it simply comes to some value and does not allow. After decreasing the values ​​on the analog, it immediately became possible to lead to them and digital TV.
A similar solution for QT526 writtenhere.
Sometimes it also happens that the alignment of the volume control range is not even necessary to bring to the same volume level of digital and analog TV (all the more so in the case of analog TV self-administration such as a private home ownership is irrelevant), but rather to adjust the smoothness of the curve. For this case the adjustment process I described QT526here.

Questions about programming controllers
So, friends, this section is dictated by the ever-expanding circle of "friends" of this topic and more and more often emerging issues on the most difficult - the process of firmware controllers. The process of firmware controllers varies depending on the type of iron. And before starting, I have to explain something in order not to be confused in the future by those for whom this topic is new.
So, at different boards of controllers installed MCU (this is the main chip - Micro Controller Unit) of various "intelligence" (I apologize, but I am so easier to express my thoughts). Those. The controller designed for the monitor does not need "brains" of the controller with a TV and a media player. This would simply be shooting a gun on the sparrows. And, since the latter are also different and the presence of a USB port, the firmware process is as simplified as much as possible - everyone knows how any controller with TV on board is selected. Another thing is the process of firmware of the controller, which does not have such a wonderful function. And this is a rather extensive list of models in which there is no USB ports. What is in this case? Again, a little lyclue ...
Aza ... On the boards of all controllers, the memory chips are installed in which both the entire controller and variable variables that the controller MCU records the controller in the process of operation, are stored as an algorithm. Variable values ​​are different modes, settings, scanned and stored channels (in the case of controllers with TV), as well as installed adjustment levels and selected inputs. Any change in the status of the controller is accompanied by the recording of this state in the memory microcircuit. Accordingly, if after any action to read the memory dump and to check it with the previous one - the dumps will differ. Since 2000, almost 100% of the models of controllers began to use the memory chips. "25 series". The number 25 is present in the title of all manufacturers of these chips. For example, W25x40, M25P40, 25LV040, AT25DF041, SST25VF040 is just different names of the same chip depending on manufacturers. In the world 25 series is the so-called. SPI Flash. Those. The memory microcircuit that makes exchange with the periphery on the SPI protocol. So, if you take into my hands this chip (only the microcircuit, not the controller) and make it easy to flash, then for this we need a programmer for a microcircuit that will power it according to the SPI protocol and nothing else. However, this path is clear, it cannot be convenient for manufacturers of controllers. Due to the fact that the controller MCU also interacts with this SPI microcircuit, MCU manufacturers laid the ability to flash SPI Flash across another widespread protocol - I2C, but already software tools of MCU itself. Those. We take a programmer that works on the I2C, connect it to the MCU on the DDC channel through the VGA connector and safely flash the SPI Flash by the controller forces, since the programmer interacts with the MCU using the I2C protocol, and the MCU in turn interacts with the memory microcircuit via SPI. What does it give: no need to get a memory microcircuit to flash it. Yes, sometimes it helps only dropping and direct programming, but it is more likely to flash on I2C. What is this in the VGA connector, you ask? If you look at the VGA pinout, you will see that there are SDA and SCL tires that are fundamental I2C protocols. But in the composition of the HDMI connector also have these two tires! An, no - for programming the controller, they are not involved, only VGA (and this is not a whim of the firmware - this is an unlawful rule of MCU manufacturers). And in controllers that do not have the VGA entry, these tires are derived for a special connector for firmware.
For what I wrote all this. So that there is no confusion in what and with what programmer it is stitched and the most important thing is how it is stitched.
By the way, television controllers in addition to USB can also be flashed via the I2C protocol via the VGA connector. Moreover, in comparison with the standard method (via USB port), this method is "low-level". Those. they can even “raise” a contorted controller. The reason is simple - this way of flashing, in simple terms, occurs at the hardware level.Here ispositive experience fromRxmaxx .
Well, now closer to the subject.
So, we have a controller on our hands. What do we need to flash it on the I2C bus? All that is necessary - you need a software that "understands" what is this chip and what and how to pack the exchange protocol to the MCU "gave good" to the SPI Flash firmware and the adapter for communication with the controller (the people called "jig" from English jig). Oddly enough, but finding and installing the software is the simplest. But the adapters ... The release of each chip is accompanied by a mandatory output of software for its programming. As generations changed chips, the software will be improved, new libraries are added to it to support newly manufactured chips and support available computer interfaces. Nevertheless, the software itself is tied to the adapter circuitry, with which the controller is stitched. But here it is precisely a big "ambush". The fact is that the simplest (circuitry) adapter can only be for the LPT port. And even though making it himself will turn out in the cost of about $ 2, "branded" jigs are sold in China by $ 15-20:
Attached Image

But after all, the LPT port has already been "talked" several generations of computers back. What is the reason, you ask? And in the fact that the programmer is a harsh piece of iron and he does not need "Ryushechki" from Win7 ... 10, and industrial samples are just spinning on Embedded versions of WinXP. A strange thing, but most of the software listed above does not imply work with a consistent COM port (at least the situation with it is still much easier than with LPT) and there are no such jigs accordingly. Although, not quite so, I did not say a little. I want to say that I never met a single ISP programmer under the COM-port on sale, nor even references to such, but they say they exist.Here(on the second page of the topic) such is mentioned, and even theoretically would approach our controllers (as it is under Mstar), but in the same place they write that it does not work ...
As a result, of the "modern" is only a USB port. Although, the most interesting thing is that it is also serial and USB jig is usually a hardware emulator of a COM port. However, industrial USB Jig costs around $ 50, and self-made ones are associated with relatively complex circuit solutions.
All of the above allows for many to make a disappointing conclusion - the firmware of the controller is very complicated, troublesome, and in some cases costly. However, not everything is so sad.
Above, I mentioned that the memory chip can be flashed directly using the SPI protocol if it is dropped. Immediately the question: what and how to sew? For this, the Chinese programmer is very well suitedCH341A(look for Alibaba on the same tag). Its cost is low - within $ 2. With the software, problems are possible for him, however, there are a lot of developments on working with this programmer and you will find everything you need (for our theme)herethank you so muchNewview . True, there is one nuance - the chip should be dispensed. Newview mentioned in his message "clothespins". This is a special cable-adapter with clips, which clings to the legs of the chip like a clothespin. TO DO NOT REMOVE IT. This cable helps in many cases, but with respect to the controllers I have great skepticism about it. To make it clearer, here are two schemes:
Attached Image

The programmer is adapted through the clothespin to the SPI Flash chip and serves me. And now think: will the dead programmer pull the section of the scheme in the second picture when the MCU consumption current is 500ma? Here you have a problem. If someone says that, they say, "CH341 does not sew through the clothespin due to the fact that it is poor-quality," you know what the answer will be correct - the programmer simply does not pull the power controller. If anyone says that I came up with something - take the controller on the RTD2662 in the hands and turn it in my hands. It is made exactly according to the scheme on the right, and consumes about 350-400m.
And now, when you are familiar with the theory, it remains only to give references to software and bring jig diagrams.

Yes, because the serial port did not dream much that it can do parallel. However, the USB version handles the usual tasks in the same way as the LPT version.
The programmer can flash both controllers and microcircuits, depending on the jigs used.

2. Software from chip manufacturers can be registered (when it is manufactured by a chip manufacturer):
- Realtek has released the RTD_ISP Tool for its chips,
- Novatek company (in the days when Mediatek had not yet absorbed it) - Novatek Easy Writer,
- MStar - MStar ISP Tool.
... and universal:
Due to the wide range of vendors, the controllers use one program, a very primitive one - Device Well MCU Isp Tools and MAYBE able to work with many chips. I do not know - I have never succeeded (I will say the reason later).
There is another well-known software ROVA ISP Tool and ROVA ISP Editor (heresomething about him).
By the way, the program editors (ISP Edit) are also found in name manufacturers. However, editors are so specific that you need to know very well how to use them - everything is not the same as in the usual HEX-Editor, but much more confusing.
Not so long ago, the LPT Jig scheme, which is used in conjunction with the Novatek Easy Writer program, came into my hands:

Compared with the jig for Postal2, there are noticeable differences in connection with the parallel port. I suspect that all other branded jigs are built in the same way, and this is the reason why the jig from Postal2 did not work with Device Well MCU Isp Tools. This is not a fact. I did not check (because I still need to collect this jig, but I don’t see the point, as I need Postal2).

As I said, the controller firmware is carried out through the VGA port. Well, since there is an I2C bus (for firmware !!!), then bright, minds find other, alternative ways to flash through this bus.Heredetailed manual fromNewview on programming the controller (Realtek RTD2660) with the help of Arduino. Why not?

The only thing - maybe on different controllers something differently, but nevertheless on another site ransuchamendment. Anyway, the main thing - the way it works ...
As mentioned above, the Novatek Easy Writer program is required to program the M.NT68676-2A controllers. But the program itself is not even the floor of the case, it is freely available. The main thing - the jig and ports. But with this a little tight. Since this controller is not at all rare and is used from time to time by our comrades, it is also necessary to program it as well, that is, there are two ways:
1. purchase a regular programming kit for it (which is, you see, absolutely no ice ...)
2. Independently prepare a dump and pour it into SPI Flash yourself.
The meaning of the dump preparation procedure:
- take the necessary firmware (they are in .hex format) and roll it into .bin
- copy all the firmware and paste it into the end. Those. double array Save to binary.
- Pour this binary into the flash.

What is EDID
1. EDID is first of all data. Hence it is "they." However, it is not always convenient to write like this - so do not scold if it is in the singular masculine.
Let's try to figure out what it is and for what you need. First of all, the contents of this data are intended for a graphics adapter (video card). This data block (in the firmware of any controller) with a capacity of 128 bytes, to which "refers" to the video card for information about what the controller is capable and what permissions can be issued for it at its output. In each interface (VGA, DVI, HDMI or EDP) there are SDA and SCL tires - i.e. The components of the I2C tires. The firmware (as already mentioned in the previous spoiler) "charges" a controller memory chip (SPI Flash) with all the necessary information controller. Including EDID blocks - they are in a certain defined address of memory. SDA and SCL tires from connectors come inside MCU. According to them, the video card refers to the MCU, he gives it data from the EDID block, the video card receives the answer and "decides", which permissions can be offered. Under the word "Suggest" implies the procedure for selecting permission in the properties of the graphics adapter - come in and see which permissions are available. It is this list of available permissions and "dictated" video card EDID block. For each of the mentioned interfaces in the firmware contains its EDID block. Those. If there are two in the controller (for example, VGA and HDMI) or three inputs (VGA, DVI and HDMI), then for each of them there is a block of EDID.
2. In laptops, about the same situation, but the physics of the process is different. There are used matrices, as part of the interface of which there is its own I2C bus, and inside the matrix is ​​chip (EEPROM, 24 series), in which only one single EDID unit will flash. There is nothing more in it, only this block. And in this block there is information only about the native resolution of the matrix and no other. A laptop video card takes information also by the I2C bus directly from this matrix chip and gives an image to the matrix, taking into account the data obtained: resolution and timings. Why so you ask? To understand this, you have to include imagination. Helping:
3. Any matrix has the concept of "pixel" - a point formed from three color components. When we say "Resolution" - this is the maximum possible number of displayed points horizontally and vertical for a specific matrix. Pixel is a "physical" point of the matrix. Those. If you light up (or darken) one pixel, then on the screen we will see a point with clearly defined edges. Those. If the matrix has a resolution for example 1280 * 1024, then it literally tells us that the horizontal matrix can show 1280 points, and vertically - 1024. And now imagine that we are trying to submit a signal to this matrix with a resolution of 1024 * 768 ( hypothetically of course). In this case, one point of the resulting signal in the geometric measurement will be larger than the physical point of the matrix both horizontally and vertically. What we will see: yes, the 4 physical pixels of the matrix will be involved to display such a point. But after all, the filed signal is not kathed in an integer from the resolution of the matrix - therefore the picture will be strongly distorted. Based on this example, it can be easily concluded that the clearest and high-quality image can be obtained only by applying a signal to the matrix with a resolution of exactly the corresponding permission. At the same time, it does not matter, high resolution in the matrix or low,the clearest picture will be obtained only with such a correspondence . Only the size of one pixel depends on the resolution of the matrix and its diagonal. I hope this is clear.
Go back to start to the second point. So, the laptop's video card reads data from the matrix and gives the same resolution. This is not surprising - in a laptop there is only one matrix and it works only with it. So the choice of the graphics adapter parameters will be a single resolution equal to the resolution of the matrix. There will be no others in this choice.
Now closer to our topic. Since we have a controller and there is some kind of matrix that should work together. But the connection scheme here is already not at all in laptops - the matrix is ​​connected to the controller output, and the digital and analog interfaces are to the input. As I said above, as a result of the fill with the correct (for this matrix), the controller must work correctly with incoming signals. From the previous paragraph, you must understand that the input signal with the same resolution must be optimal as the matrix. In this case, such a concept is applied as "native resolution". But the video card should know the native resolution of this bundle controller + matrix! It means that for correct operation on this video input in the firmware there must be an EDID block for this input, which contains information about native permission. But there is another moment: after all, the controller with the matrix from the point of view of the computer - nothing else as a monitor. And for all monitors, it is typical to have a specific set of supported permissions on board so that the computer's graphics adapter "could" navigate them. What is meant. The best permission for the operation of the monitor is clear, it is native. In the EDID blocks (forgot to say, they are decrypted using special editors) This concept is called Detailed Timings (still Native or Preferred Timings). All other permissions supported by the monitor are called Established and Standard Timings. For which they are needed at all: during the boot, the OS on the screen passes various stages - Post, Bios, greeting screens, and finally the OS interface itself. All of them have different permissions and update frequency. In order for the monitor to display all these steps, the graphics adapter "looks" to the list of supported permissions and in the presence of the desired display the image on the screen. If there is no need, there will be either a black screen or the nearest permission is enabled. It all depends on the graphics adapter, the manufacturer of MP and BIOS, as well as on the circuitry of the monitor scalera. All of the above refers to "computer" interfaces (i.e. VGA and DVI). And here the whole "commitment" can crumble from the unscrupulousness of the firmware. If in the old models of controllers with this was all right, then there are such disadvantages in modern. The reason is simple - the first controllers were the "brainchild" of capitalist Chinese (Taiwan) and were very carefully worked out, and the latter - already riveted in Socialist China and already with an admixture of Chinese "Avos".
4. And what about the entry of HDMI? But with him is not so simple. The thing is that the HDMI is a multimedia interface and was originally calculated on the use of video engineering. Since HDMI digital interface - it started in digital TVs, i.e. HD READY standards (first 1280 * 720, later 1366 * 768) and FullHD (1920 * 1080). "Television" language is the resolution of 720p and 1080i, 1080p. In the overwhelming majority, all media executives are spinning on the issuance of these two permissions. Now back to EDID. It is easy to understand when it comes to a video card, then a clear thing is a computer in any form (whether it is a computer, a tablet, some linux mediaders, etc.). Those. Those vehicles in which the video card can give any permission to exit HDMI. But the receivers, television consoles, budget media players are not at all designed for any arbitrary values ​​- they are just 2-4 standard television permissions. Why I say all this: to the fact that the HDMI EDID EDID has almost no one ever worked so carefully as for VGA and DVI. Those. In the data of EDID HDMI, at best, it is usually a rule of all the resolution of HD Ready and Full HD. To connect any media executing it is quite enough. But with the connection of the computer there are big problems. Well, if the HD Ready or Full HD matrix is ​​connected to the controller - in this case, both of the parameters of the graphics adapter will be visible and you can choose the desired (native). Then everything will be fine. But if there is a matrix, not falling under both listed, then the following picture occurs:
Suppose we have a matrix 1280 * 1024. From the entrance of the HDMI video card sees the controller's ability to operate or HD Ready or Full HD. Other permits it does not offer. We choose the lower (for example 1280 * 720). In this case, both permissions (computer and matrix) have the same dimension horizontally. So horizontal clarity will be in order. But the vertical 720 lines of the slage of the controller "smear" in 1024 lines of the matrix, i.e. For one point vertical on the matrix 2 physical pixels will be shone. As a result, it will be "soap" vertically and nothing can be done with it. If the computer sees a 1280 * 720 permission in EDID, and 1366 * 768 (which may well be), then the final picture will be even worse. If you select the 1920 * 1080 resolution on the video card - too, nothing good will work. What this tells us - only about the fact that HDMI input in universal controllers in many cases is not suitable for using such a controller as a PC monitor.
5. It is possible to fight shortcomings in firmware, but alas, only in the controllers on RealTek chips. In the topic header, these are controllers on the RTD2662 chips, RTD2660. The fact is that in the firmware of Realteches, the EDID blocks are present explicitly. They are easy to read, edit as it should (of course, if you know how, who needs, ask questions) and re-introduce into the firmware. And then the HDMI input perfectly performs all the functions of the monitor on any desired resolution. As for MediaTek (these are all controllers with TVs) - alas, to pull out the EDID block of them is not possible, since neither in the firmware nor in the dumps in its open form no - the MCU itself generates an EDID from the firmware. Even if it would be possible to read it, then where could I pour the corrected EDID? How this matter is to decode - there is no such information - respectively, there is nothing to correct. All hope is only on the firmware that is available. If something in them is incorrect - it will not be possible to correct.
True, one bright mind (and maybe not even one, but two or three) here on the forum offered to work with EDID "crowbar". Those. stupidly cut a square bus i2C at the connector and hook up to the connector an EEPROM with the necessary EDID of the type as done in laptops. Those. in this case, the video card will not apply to the MCU, but to this microcircuit. I have not tried it, but why not?
There is another way - this is to force the video card to give the necessary resolution through force. But this method can be implemented not with every graphic adapter. I managed to get my Radeon HD 7350 to issue 800 * 480 for the controller, in the firmware of which there was no EDID block at all. But with the NM10 graphics on the "atomic" motherboard, such a trick did not work.

Links to useful sites
I nevertheless decided, while finding something useful on the world wide web, to post it here. It will not be links to the stories of anyone about how he implemented this or that structure, namely, on sites with an engineering bias, led by other engineers. One head is good, but a few heads are strength. I understand that many do not even bother to read the cap and climb with questions in the subject. Therefore, these links rather for "inquisitive minds."

I also ordered there. In terms of detail? Receivers can be on R840 and R842 chips. Under different receivers - different softinki. The first time I laid out the firmware under the board with the receiver R840. And sent to R842. So I laid out the other firmware.

I came across motherboards with Lvds interface, as I understood them, too, you need to sew under the matrix. And where are the firmware on them?
There is nothing to sew there. There you need to slip EDID. In the manual for these motherboard everything is painted how and what is being done. You can go to the pccar forum - there are quite a lot of experience in engraftment of matrices to mothers with LVDS, starting from mothers on atoms. The essence has not changed yet ...

I will try to pick up the matrix n070icg-ld1 to the board on V59
There are several nuances in matrices N070ICG-LD1. At first they went out two revisions. Old LD1 walked with a 39-pin two-row connector (whose contacts in a checker order), new - with a 40-pin single-row. According to DSh, the old LD1 "knows" to work for 6 and 8 bits, new - only 6 bits. After some time, the new N070icg-LD1 was renamed N070ICG-LD4. Datasheets on it not. Pickup - take a dsh on LD1 (39-pin) and increase the numbers of its pins by +1 - get the LD4 pinout. And of course there is no RXO3 pair and there is no SELB.

What I crossed out is not needed (it will be needed only when you attach this matrix to the motherboard, which was asked above).
What I saw in a square - honestly, I don’t know what the backlight voltage is (pinout taken from 8.9 "Chungwa - it has 5V), but most likely 5V too.
Pins 20 and 21 on this matrix, they are divorced, but apparently some kind of service ones - so do not pick up anything
Pins 27 ... 30 - in theory pins of a wheelbarrow. So, too, do not cling

The board seems to be like for both versions of the chips (V29 and V59). The tuner is digital. (DVB-C interestingly supports, or only terrestrial channels?)
If you do not pull out the extra wiring from the loop, it will work, - why does not the thread burn?

Rep: (563)
My V59 is still waiting. I have a 27 "TV set with CCFL backlighting - I still have to conjure it. Now there is no time ...
About V29 - read on the internet, for examplehere. All boards are sewed in the same way. Only firmvara need it for this fee. Look for a binary in it under 1024 * 600 1ch 6bit and forward.
Of course, extra wires should be pulled out of the cable - they are easily removed.
As for the backlight - of course you have to pull them out of the rectangular black connector and pick up another connector to the backlight connector. They are not exactly divorced on the LVDS comb.
And about the wheelbarrow: it also drives "brains", i.e. computational part. Tap the controller to it and to the USB port of the computer.



Rep: (563)
Oh and oh ... Honestly, I don’t know ... The pinout 10.1 "of the matrices seems to be completely consistent with the N070ICG-LD4. But I don’t know what exactly the connector’s entry into the matrix is. I usually do adapters to it. But as for the finished connector ... Well, if it would have entered there, it would be the most non-haemorrhagic way to connect it. ..

I will continue, from the laptop, the cable has pinched 40 pins and into the matrix, it stood up normally and it seems to hold, I'll probably order the cable from the Chinese, it's all easier than to solder the cable itself.

In my life, I burned a lot of things, and I did and repaired - a lot, But it turns out to be repaired, when you understand what you are doing, until you catch up .... Once there was such a "shaking" when I started to deal with computers (there are no circuits , there is no guidebook, a bunch of microcircuits, there is no one to explain), then I realized that everything is simple, but from the beginning there was a jitter. But then the hands did not shake, the vision was 100% ...

Of course shake up. None of the controller on the LVDS comb backlight never divorced. At least 5 pairs of wires will be removed from the cable (blue and white). Here and then put them in the right pins FIX30: VLED, GND and BACLIGHT ENABLE, and on the other hand, make the right connector in the direction of the Invertor connector of the controller.

And secondly, again about the previous message. I do not want to repeat again and again, it is easier to explain "on the fingers". We look at the picture and carefully read what I wrote there:
