Rep: (512)
The second life of LCD displays and monitors

Due to the fact that this forum - it's not a professional, and completely voluntary, and the topic is relatively complex, please kindly to newcomers: first read the cap, so as not to set the topic of questions that are here. If something is not clear - be a lot of thinking and re-read again, only closer. I assure you that 95% there is a question there are all the answers. Cap constantly updated. I therefore recommend to beginners and sometimes look at her ...
Main point
This theme is dictated by the presence of many of the "surplus" in the form of matrix (TFT displays) remaining from nout- and netbooks, tablets, monitors, and even TVs. Therefore, here we discussed studies for their application embodiments. The theme is very difficult and requires a lot of attention and a careful approach to their projects. Those. "Impudence" in the best case you can not achieve anything, and at worst - even breaking anything. I'll do better as a teacher - try "on the fingers" and professionally chew various technical details that arise in the process of realization of this or that 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 - a display controller. He called it "the controller" and not "scaler", as is customary in common. Scaler (from the word Scale - the scale, the scale) - is one of the components of the functional diagram of the controller, which is responsible for image scaling. Controller - this is the "piece of iron", which deals with the transformation of various interfaces (HDMI, VGA, CVBS, RGBs) into signals "clear" matrix. In the vast majority (almost 90% of the market) controllers focused on the connection matrices with LVDS interface. To connect the matrix to the controller, make sure that the controller supports this matrix, as well as to comply with a list of conditions that must be satisfied and the controller, and that it should still be navesheno. The controller itself - is actually "harvesting", led by the firmware. And how it fits a particular matrix, the entire success of the enterprise.
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 availability of iron, which is produced in China is for homemade designs. On the one hand it is good - basically all Chinese controllers are designed for maximum coverage of the available templates. But be sure to mention the fact that not all 100% of the existing matrix can thus be put into the project. It is understood that there are a number of matrices that can not be called universal, interchangeable, etc. There are also quite unconventional loner, but glad that they are not so much. It is about matrices with infrequent interfaces, "lift" that is quite difficult, and sometimes impossible. These same hard prizhivlyaemym can safely carry and matrix purely individual time characteristics, which were laid on the plates or netbook (wherein these matrices were first in life). Not every controller is able to give these characteristics as calculated still to some "average" and standardized parameters in the vast majority of the firmware. Controllers which could hypothetically get it working with such matrices - those that "TV" on the board (to be lower under the spoiler). Those. those in settings where there is a point map LVDS, in which there is at least some sort of a choice of 16 preset parameters laid down.

1. It is necessary to stock up on the documentation for your array - without the success of the event is nearing zero. What I mean. Documentation on the matrix - a .pdf file that accompanies the public release of the matrix itself. Properly called Datasheet. It spelled out everything from electrical and optical parameters of the panel itself and illumination parameters to geometric and installation dimensions. There is bound to have data on its interface and its connection diagram. A man with no experience without connect matrix will be very problematic. Datasheets in the vast majority of the English language, it is very rare, but caught in Chinese or Korean. Therefore, do not expect that he will be in Russian - no one ever puts these things. Datasheets are searched for on the Internet via a search engine on the tag "[name of the matrix] .pdf". Collect and search. I note that site (he first encountered in the search for any matrix) - the world's only "guide" and the datasheets do not just handing out, just for the money. So for him to find no hope. You can try to look into thelibrarybeyondinfinite site. There certainly is not paneluk, but quite a lot of things and is distributed free of charge. However, it often happens that the documentation for the array is not - it is not the fault of forumtsev and not mine, and the matrices producer. If faced with such a situation, try to look for a matrix of the same name (or a very similar name), but other audit or other suffixes - in 95% of cases, it helps. Also in this case it helps to search for compatible matrices models - for example, see websites selling and maybe there will be transferred to compatible part number. Be the logic and wit.
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:
- matrix interface LVDS c "portrait" resolution (when the technical data indicates that the number of horizontal pixels is smaller than the vertical, for example, 600 * 1024 800 * 1280 - Refer to the website by name Matrix - everything write "right"). Why I drew attention on the type of interface - because matrix MIPI interface as opposed to the matrices with LVDS interface, contrary to the vast majority of the portrait, and for the "turn" on the 90-degree image corresponds to the controller, which, of course, has a much greater intelligence, than LVDS controller. And in those plates, which were LVDS portrait template for the correct orientation of the image meets the general processor.
- 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).
- Backlight in tablet matrices only LED. Depending on the type of matrix, it can be deduced separate line connecting LEDs, and can be operated from the driver built-in illumination matrix. It is clear that in the first case, you need a separate driver, providing the LED current according to data from the documentation on the matrix. Built-in driver eliminates the need to locate outside. He usually eats from what the fixed voltage (3.3V, 5V, 12V supply voltage often has wide limits, for example from 5-7 to 15-20V). Such lighting in budget tablets do not occur.
- 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.
- LVDS interface to monitor matrices is 1- or 2-channel. Single channel LVDS is usually found in the square matrix with a diagonal of 15 ", rare in the 17 '. However, since the 17 "and above are usually used in 2-channel premium monitors 23." ... 27 "- is a 4-channel LVDS interface monitors are always 8-bit exceptions are some very old monitors small diagonal (11.. - 15-inch) - where there are 6-bit matrix and modern premium monitors, which is seen even 10-bit interface.
- Backlight is in the monitor matrices CCFL (fluorescent, 2- and 4-lamp - Edge An, less frequently, in large diagonals can be 6-8 tubes - the Direct) and LED (1 to 4 ... 8 groups of LEDs). What CCFL, LED that lights in monitors involves the use of regular backlight driver. He is generally aligned with the monitor power supply and is controlled maynborda. Lane C Enable (or BLON) signals are applied to it (enable) and the PWM (or DIM_B) (brightness adjustment). Sometimes in older models found DIM_A - analogue 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)
- Highlighting may be fluorescent (one linear or L-shaped lamp) and LED (one LED strip consisting of several groups of LEDs). CCFL backlight used for the driver, who was in this laptop. For matrices with CCFL backlight drivers almost all the notebooks are interchangeable (electrically, not constructive!). For LED backlight Buchnev matrices using a driver that is already embedded in the matrix, and its contact management and power output to the matrix interface connector. Matrix LED backlight driver without a built-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) into TTL structure represented by either 6 or 8 lines for each color. Since the signal on each line may take a high or low value, each of these lines is a kind of a carrier of 1 bit of information. Those. for an 8-bit representation of the "green" color in the structure of the TTL signal used G0 line ... G7, the "red" - R0 ... R7 and "blue" B0 ... B7. Accordingly, for a 6-bit RGB line representation will with indices 0 ... 5. In addition to color TTL levels of course are present and service lines with different clock signals. So all of these TTL signals into LVDS signals are encrypted, and on the side of the matrix by means of a chip "mined" from them. Be sure to note that there are two standard RGB signal location in LVDS - VESA and JEIDA. The small tablet, of notebook and monitor arrays in the majority of default is not the system of choice, and these matrices are designed to work in VESA system. You can even with some confidence that this system is mainly used in the art of European and Korean brands (regardless of the place of assembly units). JEIDA system is more focused on "Japanese" equipment. For example, in her work matrix for television SONY, SHARP, and oddly enough, it is also a "Korean" SAMSUNG. Moreover, if the television matrices LG-Philips production, AUO, BOE, ChiMei-Innolux at least have the opportunity to color coding system of choice in the LVDS, in some instances SAMSUNG production of matrices, the SHARP and even AUO (producing commissioned by SONY) this choice simply does not exist - except matrix JEIDA nothing more, "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:

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 many probably already noticed that such a controller do not care what color bit depth to pass into the matrix - it is defined by the firmware, and its capacity is enough to yield the highest. Therefore, the concept of bit depth is more related to the capabilities of the matrix itself. It so happens that small matrix with a color depth work described 6 or 8 bits per color, and the matrix 17 ... 22 in the vast majority of 8 bits per color. Therefore, the firmware is mentioned, what it is, 6-, or 8-bit. Sometimes the quantities bit capacity multiplied by the number of colors (3 - R, G, and B), and the concept can be found 18 or 24 bit - this classification is used in motherboards equipped with the output LVDS .. But most importantly, what it affects - the maximum number of colors that can transmit matrix. 6-bit matrix - 262K 8-bit - 16,7mln. I hasten to reassure and possibly someone and surprise: if you put the next two matrices 6 and 8 bit and apply to them the same image, but prepared with a maximum of shades for each individually, you see the difference with the naked eye is unlikely. How many shades will be able to recognize the human eye - is still true in the disputes can not be found, but for now is winning a version that 15tys.
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 the 6-bit matrix to file an 8-bit signal (ie leave hanging in the air a couple of RX3 from the controller), the matrix will show the brutal kaleidoscope of colors, but the image will not be correct. Externally, the picture looks like a color with very low bit depth (for example, if Windows does not put a color depth of 32, and 4 bits for example). The reason is that according to the above picture of the complete picture does not reach the matrix (after RX3 pair is not connected) -, respectively, lost part of the video.
- 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:
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 for the use of matrices with a refresh rate of 60Hz. Usually it is 6 or 8-bit one-or two-channel matrix. Many modern TV Full HD matrix often are already 10-bit LVDS interface and LVDS interface can be the 2- and 4-channel. It is clear that such a matrix to connect to the universal controller directly of course will not work. Individual items 2 channel matrices are electrically switchable LVDS interface between 8 and 10 bits - in this case special problems will not arise with the connection - sufficiently matrix switch in 8 bit mode. But matrix with 120Hz refresh rate and 4-channel 10-bit LVDS interface, without "special means" with a universal controller simply do not work because it is not for any 10-bit or 4 channel LVDS. What exactly do I mean by "special means" - this will be the second part of the "cap".
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:

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 the programming flash does not work. The first of these controllers has the firmware from almost every conceivable resolution matrix, the other two in the abundance of firmware is already heavily curtailed. The last (the one with sound) is a spartan set of firmware around the area 20. Another point. Controllers RTD2660H chip (RTD2662) why it does not favor on the resolution FullHD. According to the description of the chip is able, but due to some reasons then for this purpose it is used rarely. And the Chinese for this it is not recommended.

- controller with only one VGA input and "Jumper" Selecting a resolution under the appropriate matrix. The cheapest of all options. In addition, he does not need the firmware. When you select (and options for them, there are several), it is necessary to look at the list of the list on the reverse side of the board and a list of possible supply voltage matrix - there are versions 3.3 / 5V, and 3.3 / 5 / 12V. Another point - often on the boards of the controllers listed in the list of permissions mistakes in the bit depth of some regimes, as well as in the signature pinouts LVDS comb confused "+" and "-" LVDS line.

- controller with a full set of "computer" M.NT68676.2A inputs. Chip Novatek NVT68676UFG. for HDMI audio is decoded and output from the amplifier. 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)
Information on it there is little, so I brought the documentation to the version with a single HDMI input. There are also versions with one VGA input and three (HDMI, VGA, AV) inputs. But one thing is trustworthy - their prices yet very affordable, and I hope the same will remain. Eg version with one HDMI input costs in China for about 75 yuan. This means that all postal costs, this controller will result in the amount of 1200 rubles (at the rate of the 1st half of 2017). By the way here already Aliekspresse finished 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 and all should work HORIZONTAL supplied signal must in turn HORIZONTAL matrix. Those. we provide the input horizontal 1920 pixels, and the controller outputs a matrix (Example) 1280 pixels. What will be left on the vertical - all in proportion, ie will be the top and bottom black bars. During this process meets scaler (in the proper sense of the word) of the controller. But all this is true for video. If we talk about connecting to a PC HDMI, already everything is not so simple. After all, we (the example), the matrix 1280 * 1024 to get the clearest image signal from a computer, too, should be the same. In fact, the computer's graphics adapter is the resolution when connected the controller will not give. That's what I had in mind, calling the HDMI input "multimedia". To use the HDMI input to the controller in conjunction with a computer, without the "drums" earn unless the matrix 1920 * 1080 1366 * 768. For the designer, collected on a matrix with a different resolution, at best, will have to prepare the desired resolution using the video features in the worst (if this video card can not - such as GMA graphics from Intel) - refuse to use as a computer. For more information on this subject can be found in the second part of the cap under the spoiler about EDID.

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:
Attached Image
However, many have not been able to understand this table, so I give a picture of how it looks in kind:
Attached Image
If the situation does not clear up after this either - take good advice: drop this case, it is not up to you.
For those who are not quite familiar with the concepts of LVDS interface focuses: a spoiler above it was said that in the interface of the matrix contains the RX signal pairs, and interface controllers we see TX pair. Literally it means: RX (receive) - "take", the TX (transmit) - "pass". Matrices are "receivers" the LVDS signal from the controller, which are in fact their "transmitters". Therefore TX controller outputs are connected directly to respective inputs RX matrix. Those. TXO 0- to RXO 0-, TXO 0+ with RXO 0+, etc. It is necessary to bear this 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:
Attached Image
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 an orientation. Those. It has a value of its horizontal side, which is the "top" of the image. Part of the tablet matrix (one might even say almost half of their number of models) have the ability to turn the image of the inner electronics of the forces of the matrix itself. To this end, their interface has pins are responsible for the image horizontally and vertically. Absolutely all of the matrix of monitors and notebooks (netbooks), such a possibility does not have. Accordingly, if the matrices were placed in what is small TVs, they are from this cease to be the Monitor. Large television matrices have the opportunity, but not all. You could even say that a very small percentage. What I just said it all. Often (and this usually happens when remaking TV) matrix deploy impossible due to the fact that either so arranged the body, or fasteners are found only in certain positions. Therefore, any copyright projects impossible to do without the coup. And if in the matrix of such a possibility is not provided, it can be saved only by flipping forces the controller itself. But such a possibility only in the universal controller with the television on board. All the above controllers monitor flipping net.Tak that 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.

And, perhaps even finally a brief comment. For all matrices that are used (or used) in tablets and laptops, there is no controller, which would have only a single baseband analog video input. So if someone is a desire to make their own hands a monitor for an analog video camera (well, for example for intercom) need to be considered controllers in which the video input is present such as the "appendage" to the VGA or any other digital. For example both the first picture, or this 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 - is when the base is a light guide made of plexiglass (7-10mm thick) and the light source light into the end of the fiber. The light guide has a textured surface on a matte points. These points are involved in the reflection of light from reaching the light rays perpendicularly. Their intensity and carefully calculated the diameter and density of their location depends precisely on whether any of the faces is light as evenly as possible to cover the entire area of ​​the matrix. Simultaneously, the light guide and the substrate is a glass 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, no fiber, but the light source is positioned exactly behind the LCD panel. The light source in this case can not be one - there are several, but not so much that they even light over the entire area of ​​the matrix. Such lamps are located on what that distance from each other and if no action is taken, the image will be visible on dark and light stripes. If this LED lights - it will be visible spots. In this regard, and the lenses in such a backlight are radically different from the one applied in the EDGE. The first sheet is of plexiglass (depending on its thickness diagonally 2,5-4mm). It performs two functions - support for the glass matrix (because in fact "trough" deep matrix and glass matrix relies only on him) and in connection with a specially treated surface - optical 'smearing' of the spots of light sources. Then, also lies a layer of diffusers and then everything is covered by a glass 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).
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).
The matrices used two monitors or chetyrehlampovaya design. Lamps one or in pairs located along two long sides of the array (top and bottom). As usual, there are rare exceptions: for example, in which it monitors a diagonal of 20 "occurs CLAA201WA03 matrix with 6-lamp Edge CCFL backlight - along each of the long sides there are arranged as many as 3 lamps B monitors large diagonal (above 24.") And TVs used mnogolampovaya direct illumination of straight or U-shaped lamps. These matrices (of course) different large thickness.
The matrices tablets, netbooks, laptops, monitors and TV sets until 55-58 inches Edge lights applied as a single LED strip along the lower edge (y television large matrices is diagonal and the side). The LEDs are arranged in a line close to each other, but their inclusion circuit may have the most diverse configurations. All depends on the number of LEDs grouped together (called a string of LEDs connected in series) and number of such groups (number of strings) in this band. The total number of LEDs in a band is from 20-25 in the shallow diagonals up to a hundred large.
A number of television matrices diagonal of 28 "and more fulfilled with Direct illumination Thong (they really are made differently than in Edge backlighting - by several LEDs on separate bands).. Located behind the matrix and some applied where LEDs are radically different from those which are used in the Edge lighting - they are much more powerful, with a wide-angle light scattering and installed not even close, and at a considerable distance (relative to their linear dimensions) apart Total compared to the Edge illumination very 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")
Looking at this list, it is difficult to imagine how to turn on a lamp or LED strips in the connector. The matrices with LED backlight of plates (not cost) or laptop backlight driver is already integrated into the electronics of the matrix and the interface has contacts for controlling the light - they are then connected, without any add-ons to this terminal (the above mentioned about the backlight structure in these matrices - it was a question about the design illumination light elements, not built-in driver). What about the lights? Or thong, which is necessary to file a 4-6 lines with a voltage of 30, 50 or 85 volts, so even with the current stabilization, and even the necessary power? So for such a matrix lit, you must use 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.
Sometimes, however, the state of the lamp matrix is ​​poor. Usually notebook panels at the lamp for a long time has run down. There is a solution - you can change the lamp-light the LED, universal kits which also sell Chinese. Just need to decide what kind to take. For in notebooks (thin) matrices need to take a set with a band width of 2 mm. For matrices from the monitors need to borrow bandwidth 4mm. Depending on how many edges were located along the lamp, you should choose a set with one or two LED strips.
Attached Image
Attached Image
I note that Edge illumination design involves proper replacement. Those. if the lamp with just one hand, and the LED backlight is necessary to choose one band and put it on the same side. If the lights were on both sides (no matter how many of the lights - one or two on each face), then you need to put the LED backlight accordingly to both these facets. Put only on one face (eg in order to save) is not recommended. The waveguides used in single-lamp illumination are very different from those used in illumination systems of the two faces.
Another rather important point: "chandelier" (as we call the U-shaped holder for the lamp) is placed ONLY ONE LED strip, no matter how much it stood lamps !!! Exactly. Do not attempt to replace the lamp every single band - apart from structural hemorrhoids you do this not dobetes. I explain why. Firstly width "lamps" the order of 7 mm (thickness equals the fiber), and by the constructive and technological and optical characteristics of the bottom of the "lamps" has a smooth surface usually 5-6mm in width. The band has a width to replace 3,5-4mm and two bands are simply not properly install (and the light from the LEDs should fall on the end surface of the light guide at a right angle). Two lanes near except at an angle will not lay down. For clarity of illustration cite said:
Attached Image
Secondly, when the band lies in the middle of "chandeliers", the light falls exactly in the middle of the fiber thickness. If you move the strip close to the edge on which rests the glass matrix, then through the matrix, you clearly see the bright spots of each LED. Third power consumption. I say with respect to the matrices of the monitors. The average of 4 fluorescent lights lamps according to the diagonal consumes 30-40Vt order. By setting one lane you get 15-20Vt consumption, and if the set of two lanes, then the power gain is zero. In addition, LEDs are in contrast to the lamps still noticeably warm. Two lanes in the chandelier will mercilessly warm fiber and the matrix because they dissipate heat is simply nowhere else. One strip is surely rests on the smooth base, and which carries out heat transfer. Fourth - once the driver ... Why? Well, the last argument, which, I suppose, must permanently close the issue: the brightness of a LED strip several times the brightness of a pair of lamps, look at it very difficult because of the glare. Lamps that 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 point. Many of ignorance (or maybe because of the economy) are trying to put the plan to end the backlight LED interior tape (adhesive on the basis of 60 LEDs per meter). I want to warn you that they are absolutely not suitable for this purpose !!! Do not try to kid ourselves - but an empty work you anything good out of this venture will not get. First you get the distinct light spots and no design tricks will not be able to overcome it. The reason is simple - the distance between the LEDs on this tape are the size of two LEDs. Secondly, these tapes are not designed give the desired shade (cool white admixture with pink / purple) to obtain correct color gamut 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 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 (except for arrays of expensive laptops and tablets), the situation is slightly worse - without a full-time driver to "raise" the backlight will be quite difficult. Those. or look for the backlight driver for this particular matrix, or in China, buy generic. However, structurally it is made of course worse than native - he and the "universal". The fact that "native" driver outputs (e.g. if illumination matrix thong 4) - stabilized four channels for the strings, and Chinese usually involves their parallel connection. Will work, but it's still not quite 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 vast majority of monitors power supply when the power cord to the network is always in the active mode. Those. "Sleep" mode displays only applies to the controller and lighting, but not to the power supply - it is always at work. Signal "wake-up" in monitors only serves to illuminate - i.e. only one tire (BLON, BKLT, INV_ON, BKLT_EN, BL_EN and like abbreviations) which starts the inverter (driver) highlighting. To sum up the above: monitor power unit is always in operation, and on / off monitor - the result display state lighting circuit (which, respectively running / not running) and operated by this scheme only one bus. The exceptions are large monitors with CCFL backlight - they are more like BP TVs.
BP TVs differ significantly from the BP monitor. The fact that with regard to monitors, power consumption in the difference between the pilot mode and the working is small - for example 3 W, and 40W, respectively. Those. 40-watt power supply in a standby state of quiet at idle and it is not beyond the scope of its normal functioning. In the televisions (e.g. lamp-illumination) consumption in standby mode as well 3-5Vt, and in the working - up to 180W (42 inches). It is clear that to get to work such a powerful source of idling technically difficult - it simply will not give the normal voltage and current for standby. In such a low-power BS installed separate power supply for the standby mode (called its output on circuit boards like Vstb, Vsb), a basic (strong) power source is turned on by a separate bus. In this tire BP boards designated as ON_OFF (sometimes N_F), S / B, and that in this way. Repeat - ONLY powerful power source is activated by a signal, which are supplied from the backlight inverter power circuit matrix, audio amplifier, etc. In this case the signal is not responsible for the inclusion of the backlight. Its inclusion responds completely different signal. Designated it as well as I called the paragraph above. For what it's done. If you look at the timing diagrams, the backlight is turned on after a pass all the processes related to supply power to all the components of the TV. This prevents the contemplation of the screen most of these processes. So, summing up of what has been said: the TV power supply "on duty," one source, and TV work provides another. Included in it unlike the BP monitor two control signals - one power supply unit includes a powerful, the second - the backlight. I hope intelligibly explained.

We now turn directly to the discussion of wiring diagrams.


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.
Power supplies monitors usually built ( "build", if we carry on monitors with CCFL backlight) scheme into two voltage source - + 5V and even "what is." Why "what is"? Yes, because it can be from 13 to 22V - it all depends on the type of power supply being calculated on the same board inverter backlight lamps or LEDs. In addition, not the fact that this is the second voltage is supplied to the controller - more often it is nothing to do there. The controller is powered typically by + 5V and the matrix - or + 5V or + 3.3V. In the latter case, the stabilizer + 3.3V can be either on the controller board or the board power supply, but actually it does not change - the primary for him are all the same + 5V. But this is not important. Source + 5V firstly high current, i.e. may issue a current to 2,5-3A, and secondly it is only on the power unit, by which the feedback voltage to stabilize. And if he stays unloaded, then it is likely to issue an unstable voltage source inverter power. Those. no load on the 5-volt voltage source at the output of the second source at said nominal 13V (for example) may range from 13 to 19V. Besides the illumination source is designed to supply maximum current 1-1,5A. And if so, then 1-1,2A "eats" the inverter and power to the controller (if the controller is powered from it) will be nothing at all. As a result, we get a "squish" as the operation power supply overload. To avoid this, the controller must be powered from a source of + 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 I mean by this phrase: if the matrix is ​​powered by 3.3V, then picks up directly to the pin or to an electrolytic capacitor Poshin + 5V, which stands at the output of the built-in DC-DC converter, and if the matrix is ​​5 volt (and this is just the pin busy jumper) - then only to the condenser. Or look at where the controller runs bus + 5V and select a comfortable place where you can solder to it. For controllers V29-V59 is a stabilizer 1084, a resistor for power amplifier, etc. This bus is easy enough vyzvonit on the location of the stabilizer feet in 1084 (picture to V59 !!! for others - will 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.


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
Attached Image
As seen from the figure, these are the power units, which are used in televisions flashlamp backlight inverter which is present as a separate board, fixed on the back of the matrix. A distinctive feature of them is quite powerful transformer, from which removed the inverter power supply voltage (+ 24V), the vast majority of 12V (supply to almost all units and SSB if any - supply of the logical part of the matrix). It is still possible on the sources of power for audio amplifiers. They then we just are not interested, and I do not even drew deliberately because they can not work and load it on anything not affected. Standby mode is implemented as a single low-power source that is always running, if the cord is plugged in. Voltage Vstb I deliberately do not have, because it can meet the dimension of 3.3V, 3.5V, 4,7V, 5B and 6B, it seems even (perhaps the last I'm wrong, but in a very old models could be such). However, the main power supply (+ 24V, + 12V) operates only in the active mode, i.e., in standby mode, the TV these voltages are not available.
The above-mentioned backlight inverter (so-called stadalone, the one that hangs on the back of the matrix) is another, in my opinion a wonderful feature. Almost 100% of these inverters are powered by a 24V (and therefore if the matrices are similar in size - means they are interchangeable, I'm an inverter under otherwise identical characteristics), but this is not important - almost all of these inverters have two entrances brightness control - the PWM (PDIM) and analog (ADIM), which switch between these modes special Ping. Typically ADIM not connected, but it can always involve rearranging the wire connector of the inverter and taking measures in the inverter switching ADIM mode (in this case, it is included within the embedded PWM, which is controlled by adjusting the voltage). So that the inverter is easier to adapt the brightness adjustment with universal controller.

b). PSU TV on EEFL lamps
Attached Image
In principle, the differences from the previous PSU there are also significant, although the project on the basis of universal controller is not much affected. The main difference - in the matrix do not have a separate inverter and it is on the PSU board. Why is that? Because the lamp EEFL (External Electrode Fluorescent Lamp) are configured such that they can be connected in parallel and the entire assembly is removed from the lamp illumination matrix two wires. Accordingly, there is no need to mnogotransformatornom inverter (as in the case of CCFL lamps). All other nuances mentioned above for the PSU previous, valid 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 - controller on duty washing PSU voltage. This scheme is suitable for cases where the standby supply voltage is equal to 5V and it is filed as discussed above in the paragraph about the food from the monitor PD (but unlike Example through a diode). How it works. Tested + 5V via a diode and it falls to about 0,3-0,5V (better to use a smaller drop 1N5817). Thus in the 5-volt bus controller receives about 4,5-4,7V. This voltage is enough to linear regulator has issued on its output 3.3V + sure to supply the controller chip. The fact that the voltage applied to its input must be higher by at least 3.3 V 1.1V (i.e., not less than 4,4V). In standby mode, the controller consumes less than 100mA and this is the load of the power supply standby PSU. When we "awaken" the controller, he gives the command to the output On / Off connector "Invertor" to turn on the (...). I did not say, to turn what. And all because if you look at the listed PSU circuit, you will notice that they are present SEPARATE pins to start the main power supply and to start the highlight. In our case, we simply joined together and a controller to successfully launch both.
Thus, the controller sends a signal to turn on the backlight power supply and ground. Thus there is a main power supply voltage + 12V, which is connected to the standard connector of the supply controller. Next, it is converted to + 5V and it is in turn applied to the cathode of the diode. The "correct" power supplies when applying permitting voltage Power On output voltage of the standby unit decreases slightly (as conceived in the diagram), the anode voltage drops below 5V and diode locked, power from the standby power supply is turned off and the controller continues to feed already from + 12V, coming from the PSU. I must say that not all duty power supplies are completely "honest". It is likely that the scheme does not provide voltage drop in standby power supply active main mode. No problem even if the diode is not closed, will not arise. At least the controller exactly is securely powered by the built-in DC / DC converter and the power supply duty, this situation does not threaten. When you switch the controller to the standby mode, everything happens in reverse. This method is no longer a theory but a proven and 100% uptime (I applied it in his latest project can be found under spoiler prefabricated).
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 of the second scheme does not require the intervention of the controller circuit, then this option can be recommended to those who are afraid to go into the controller board with a soldering iron and generally spoil the presentation controller. Just the second circuit pulls the compulsory purchase of the converter. By the way, do not have to buy it in China - they are there for us and it cost about 150 rubles (more expensive of course than in China, but did not wait for a month ...) ... WARNING !!! Adjust the voltage step-up converter is better to avoid trouble in advance. This can be done even without a 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 can easily be seen, all three different embodiments PSU, mentioned above, contain standby power supply (e.g. 5VSB). What is it: a low power voltage source for maintaining the SSB board assemblies in sleep mode. Of course varies greatly television circuitry and standby PSU may be for powering the low-power nodes (e.g. remote controller and supervisor), and may carry power to the logical part and SSB in the sleep and awake mode - when it is designed for loads up to 2.2, 5A. That is not to guess and guess exactly what you have in stock BP standby, and were designed by the aforementioned circuit powering the universal controllers. It is about the diode in the power circuit and the parallel activation of the source of + 12V, which precisely has plenty of 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
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.


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). He put himself on the controller power supply and the output voltage of 12V it is exposed (ie it converts 19 to 12V), and the backlight inverter board just better to be powered from 19V (of course, if it allows it). In this case it will be less heated than 12V. Is powered by the controller itself 19B I would not recommend it. Well, if applied on the board chip buck converter with an acceptable voltage 20-24V. But it all depends on the manufacturer's controllers - it can install other chip with an acceptable voltage, such as 18V and 19V then the applied it immediately "pshiknet" (and even, God forbid the consequences). In the area of ​​100-page threads have confirmation of this - the controller, accidentally powered by 20-22V, flew chip DC-DC 12-5V and dragged for a more important and DC-DC to 1.2V, which powers 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:
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. Power (in watts) to the power supply output is equal to the product of the voltage (in volts) on the current (in amps). Since, as mentioned above, given off current value depends on the consumption of its load (and to the power supply indicated the maximum current value which can "give" the power supply), respectively, and the power, calculated by the above method - also the maximum possible. Those. power supply unit 5A 12B may issue a 60W load, but if the controller is connected, which consumes 1A, the power delivered power unit 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 PSU, and also in the individual inverters control voltage is regulated within 3.0 ... 3.5V. From the output of the On / Off control signal to the controller goes voltage + 5V. The controllers V29-V59 + 5V bus on controlled transistor collector resistors are of 1K. So in order to turn on the voltage signal and a signal maximum brightness level lead to 3,3 ... 3,4V, in the schemes shown above additional resistors connected to ground, the resistance of 2,7kOm. Together with resistors from the controller receives a simple voltage dividers.
In the controller z.vst3463 and the inclusion and adjustment made severaldifferently. The signal switching inverter is implemented as a DC voltage issuing from the key collector p-n-p transistor. It made it more likely for the purpose "of high-power" of this output, because rare, but still there are inverters, which are input control backlight have a low input impedance. PSU example from Phillips PFL3606 - had approximately 1k input impedance control input. Therefore, to bring the activation signal level to 3.3V, you will need to hang up on the external resistive divider output controller (it is also possible to construct it from 2,7kOm and 1K, and 2K Ohm 5,6kOm etc.). Roughly the same lookschemeand 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 controller output On / Off (or at BLON z.vst3463) is connected to the input of the backlight inverter monitor or TV. It can be called BL_ON, BKLT, ENA, B / L_ENA, ENABLE and similar abbreviations of English words backlight, enable. Will it be a direct connection or through a divider (if required) - can be solved then. But first, you can just connect directly. If it works - that no divider is not necessary. However, I wish to warn that sometimes the magnitude of the control signal switching is involved in the stabilization of other stresses PSU. Rarely, but occurs (example - PSU LG 42LN540 - there energization + 3.5V is part of the output voltage + 24V stabilizer). Then the divider required.
Yield ADJ controller connected to the input of an inverter regulator brightness. It can be called DIM, P_DIM, DIMMER, B / L-ADJ, BL_DIM, BRI and similar abbreviations of words dimmer, adjustment, brightness. If the inverter contains two inputs and A_DIM P_DIM (or B_DIM), an organization illumination found in monitors, you can try to connect first to the A_DIM and check whether the brightness is adjustable. If not - then to P_DIM. The fact that A_DIM - this adjustment voltage (analog), and P_DIM - adjustable PWM inverters and some analog adjustment (A_DIM) may or may not be soldered 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 spoiler about the lighting), I said that the way to adjust the backlight brightness, there are several, to be precise in TVs and monitors (!!!) - four. PWM adjustment - when the backlight brightness is controlled by changing the pulse width following a certain frequency, e.g. 200 Hz, and an analog - when the brightness depends on the magnitude of the applied voltage. These are two fundamentally different ways. And plus, each of them can have a "direct" and "inverse" adjustment. Direct - when the maximum brightness for the analog adjusting the maximum voltage at the output ADJ, and for PWM - maximum pulse width (actually a constant voltage level) to the inverse (backward) adjustment - is the opposite. I would recommend to first use to test your existing inverter in stand-alone mode (without a controller connected) on the subject matter of its regulation and trigger levels. To make a long time to paint all the options, I will start the inverter 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 in the start-up, which can make backlight adjustment, I recommend when you first start to apply for the regulator adjust the inverter level of maximum brightness (according to what you have learned from the above algorithm, and if your inverter adj has a maximum when filed "+ "and on / off is activated too when filed" + ", then simply connect the on / off and adj on the test inverter together on the controller while leaving pin Adj in the air). The fact that most universal controllers have adj output direct analog control. If the inverter has an adjustment on the basis of the PWM, the backlight may not light up, and you immediately determine the cause. But for this first start to do as I said. When all set up and run - then we can do apart alignment illumination - to connect adjustment and then have to carry out correctly the experiments, already knowing exactly what everyone else is working properly.
Most televisions and monitors inverters are adjustable according to the principle of PWM, and all universal controllers have an analog principle (because they are focused on working with the universal inverters, in which brightness control is analog). Hence, it is two incompatible factors. There may be occasions when the short stretch which control characteristic change in the brightness in the PWM inverter of the applied voltage is still going on (I talked about this in one of his projects), but this is the exception rather than the rule. In this case one can either opt out of dimming backlight connecting terminals BLON and PWM inverter (thereby setting the brightness in the maximum), provided that the PWM adjustment at this inverter DIRECT (or plant PWM by weight unless adjustment inverse) or not very complex to manufacture analog to PWM converter. This will be discussed at the end of the 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 directly generally not friendly - set to "maximum", he still does not light the backlight, which is normally lit when the inverter connected to the ADJ blon. As shown it is checked, the output luminance adjustment is made as follows: O chip 90 through series connected resistors 4,7kOm 1k and goes directly to the ADJ pin connector INVERTOR. In the range of brightness control on it and does not present any tension. The reason is that there must be an open collector and the chain "pull" through the resistor such 2,2kOm concluded blon. You can try to connect the scheme, which I showedhere. So try and experiment ...
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, then, if the monitor inverter is inversely related to the applied adjusting the voltage of the controller, I think this should not be a "blow below the belt" - just in the service menu you will have the backlight level these figures are not 90 or 95 (%), and 5 or 10. At the rate is not affected. I do not know on the other controllers, but such as V29, even when there is an item Pwm Invert, which can change the control characteristics on the back. In general, the ground for the 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, since such a node works depending on the input voltage, a photosensor depending on the ambient light can be applied with the same success, a kind of “direct ARD”. A little later, I have to make such a car monitor. After I try and adjust everything, I'll lay out the circuit. (did, checked - no words, how cool it works.Hereall told what and how. By the way, I did on the PIC controller, and not on the AVR)
Of course, it is possible to make such an addition on specialized chips (not on microcontrollers), for example, on the same universal timers NE555 or TL494 (I can give them a link to the concept of building ADCs), but this will be somewhat more complicated than on a microcontroller. for examplehereversion of such a scheme fromGrishanenko on dual op amps. Here embodiment of the same idea with a reworked board, there is even a video from areon .
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.

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"):
firmware file (ATTENTION !!! no folder with the file, namely the file itself with the extension .bin) copy to the root of the USB drive formatted with FAT32, switched off from the network controller to insert a USB flash drive with the firmware file (the appropriate USB connector) and apply power. If the previous firmware sets the controller at power up in the "on", then the activity will flash (by its light indicator is visible), and then the controller LEDs will "wink". If when power controller is set to "off" - just press the Power button on the keypad or remote control. EEPROM process lasts about one minute, the screen is not illuminated. Once controller LEDs "missed", the controller can be established in the "on" state (as it occurs after V59 EEPROM) or in an "off" (z.vst3463) - it depends on how the firmware itself is made. It is necessary to wait 10-20 seconds and turn off the controller (actually a TV) from the network. Unplug the USB flash drive and turn on - V29-V59 ready to work, and z.vst3463 be just, and the initial setup and configuration.
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 the last. Different controllers in different ways "refer" to the generations and to the volume of USB drives. It is not necessary for the size of the firmware to use about 1 gigabyte flash drive on 16-32-64 because stick of this size are usually fresh generations and can not be perceived controllers. It happens like this: turn on the controller, the flash drive blinks a couple of times and then nothing happens - the firmware is not. For firmware are best slow stick to 2-4 GB. And then there are problems. Most likely MCU controllers do not "see" the internal controller of USB drives some brands. So that the reliability of the firmware (as well as for a confident start of the process) is better to have a small selection of different USB drives.
- 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:

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 are my words contradict with the above two lines above. However, here I have put my words in a completely different connotation. For example you have the matrix diagonal of 18.5 inches with a resolution of 1366 * 768. A firmware permission to do so - a dozen. There are those that are on the same 18.5 "matrix, and those who are on the big television matrix with the same resolution. In this case, just to better navigate diagonally, as many small matrix are interchangeable and have similar temporal characteristics. But television just in spite of the resolution may have very different timing. Hence, a 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.

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 the firmware on your controller. The names of folders with firmware indicated by a controller chip, by how much and what kind of buttons designed tuner chip. Board per controller TSUM V29 and V59 can be equipped with chip tuners Rafael Micro R840 and R842. Read the name of the tuner can be on a small chip, which is installed near the antenna connector. Ask a topic, a tuner chip installed on your board is meaningless. This is equivalent to, if you ask members of the forum to guess what kind of tuner on board, which you hold in your hands. can not be separated for the V56 firmware, since it is only with the 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 motherboard based microcontroller TSUMV29, but not LA.MV9P, such as T.VST29-03, the firmware of LA.MV9P pour it CAN NOT, in spite of the same chip. Any card with the same chip, but even a slightly different topology (actually Scheme) should already have it their "native" firmware. The thing is that there are plenty of microcontroller I / O ports, through which carried out its relationship with the periphery. So on one particular leg of the chip card can perform one task and the other board - very different, not even related. The algorithm works on all ports just described in the firmware and of course depends on the designed circuit wiring and the entire board.

Now do the firmware:

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)
It says that you can use the firmware from one bit depth on a matrix with other (for example, if a suitable firmware simply does not). After the firmware will fix the bit depth in the service menu on the right. And it is - not only just for z.vst3463, this is also true for other controllers. All television universal controllers point LVDS map has a fixed 16 "cards" presets. But this method works, and even in those controllers, which are only 2 preset (I personally saw this as an example 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 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.

New firmware very little, but you can disable the blue screen in the absence of a signal with them. With old firmware that does not always work. The archive of old firmware, there are two folders to 2011 and 2012. And 2011 (old firmwares) even slightly different interface and some trimmed in functions, but those who use them, say that the picture is different from the more modern software for the better. As a matter of fact - I do not know, but I've heard more than once. In mid firmware folder contains the firmware for all conceivable solution. So that 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 at all necessary to acquire or make some specialized programmer. The memory dump is the firmware itself. Those. The firmware file itself is flashed directly into SPI Flash.

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 as a result of any incorrect actions with firmware (firmware is not poured on the controller, blinking light during flash sboynul computer, etc.) okirpichili your controller, you have to remove the SPI flash memory chip (8-legged chip with the exemplary name or 25Q32 25Q64) and reducing it in flash dump. Dump (English Dump.) (For those who do not know) - a working body piercing, which is prescribed in the SPI flash, when you are the controller sews regular way (via USB). Dump - this is NOT the firmware of the above files, and what is written in the SPI flash as a result of piercing process. However,heredetail painted firmware zvst3463 method without removing the chip (by the way there is no difference what kind of controller will be restored in such a way). So there is a person trying to fill not only the dump, but also binary firmware as it is. As far as it is right and what will further the work of the controller - is unknown. It is possible that if the controller will be restored in such a way that it will be possible to make a "control" - after the recovery to flash once the regular way. I would personally still flashed dump - the benefit here they are available for all controllers. Choose someone which way is more convenient - who is using the programmer for SPI Flash, and to whom it is more convenient to program via the debug. You can also do this with the 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!
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 ...

read more carefully than the first !!!!!

Chip 842 is the maximum that CAN is DVB-T and DVB-C. And MPEG-4 (DVB-T2 and DVB-C2), he does not know from birth.

On Ali sold Ledovsky lights, can look in her direction.
I already wrote in the campaign against illiteracy, which is light. LED backlight, which is sold in China, I have long enjoyed, but the fact is that it is designed to replace the lamps only in a matrix with EDGE illumination, ie which is located at the ends of the fiber matrix. A light guide - a thick sheet of Plexiglas. On its surface coated matte points of different diameter. At the edges of the point of the small and rare, to the middle of the fiber - their diameter is greater than the density increased. Thus it is achieved the uniformity of illumination throughout the matrix plane. Light guides have matrices with one lamp (LED stripe) differ from those two is the order of application of these points.
A large-scale television matrix with the CCFL has never been EDGE, only DIRECT (i.e., backlight throughout the entire plane).
The uniformity of LED direct illumination is ensured by the correct location of the light sources and the corresponding design and processing of the reflector. So replacing CCFL direct with LED direct is not an easy task. My case ishere. Classic...
Shl. For these cases, I have a few rolls of tapes in stock - the last time I took at all was 210 rub / roll. That's just for this tape you need an adjustable voltage regulator driver, not a current.

In Chinese, they are called PH-N P 2mm female, where N is the number of contacts. Here is for example 6-pin. I bought on Taobao - there they are cheaper much, but here it’s still with delivery ... It’s necessary to take different sellers from one vendor and DEMAND that you don’t pay for this price for each lot (where the cost of delivery to Russia is 200 rubles), but so that the delivery was 250-300 rubles for the whole package. Those. the connectors themselves, depending on their pinnacle, cost 25 ... 70 kopecks / piece, sell at least 10 ... 20pcs each, and delivery. So consider.

Before I bought them, I was tugging from imported video recorders - there are often such people there. Now the Vidic themselves are already rubbish, but we need somewhere to attack a pile of this rubbish. In our workshop, such were stacked in piles.
