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:
Attached Image

The controller, in turn, "prepares" LVDS signals in its depths. At the very beginning of the development of LCD technology, TTL signals were present in any controller explicitly and then encoded in LVDS using specialized microcircuits. At the current level of chip integration, LVDS signals come out of the controller chip directly without additional processing.
This begs the question: why was all this done? It's simple: to reduce the number of connecting lines. After all, the 8-bit TTL interface contains about 30 lines, and the 8-bit LVDS is only 10. Well, there is a possibility, at the very least, to call the LVDS interface universal.
As 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.

- 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):

- controllers with digital and analog inputs and with a TV tuner on board, stitched through a USB port. They can be divided into two groups:
for reception only analog terrestrial television

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.

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.

I'm not sure that the difference in firmware under 5 or 7 buttons is fundamental, because the service menu contains the choice of the number of buttons.

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.

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.

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 ...

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

This section will accumulate a wide variety of information that will help many find answers to various questions and gain experience from others. Information will be generated in the form of any links, pictures and other things that may push on the best design solutions.
Finalization of the matrix power supply node in controllers for 3463 and 3663 IMPORTANT !!!
This information is important for those who plan to install a matrix with a controller voiced with a supply voltage of the logical part of 3.3V (matrix from laptops, tablets and some monitors). More precisely, even this: the matrix with a supply voltage of 3.3V and a small current consumption - this is a matrix from tablets, netbooks and laptops. The remaining matrices this question does not apply. Matrices from monitors with such a supply voltage, due to a rather large current consumption, also endure this moment without problems.
Under the power supply spoiler, a diagram of the section of the formation of the supply voltage of the matrix in this controller is given. So, when choosing a 3.3V power supply, the limit from the + 5V bus is implemented using two diodes in series:

The scheme sketched accurately and errors can not be. As can be competent this way downward. It can even be called blunders circuit designers because ... We will not go into the jungle of radio, it just never did. Chinese engineers can understand what spodviglo them on this - unloading linear regulator AMS1117-33, but not the better for it. Moreover, this forum has suffered from this annoying lyapa Chinese engineers from the two, though not very valuable, but ditching dies in her arms.
I strongly recommend to protect its design all with whom she had made on a similar matrix. What you need: compact DC-DC converter that will be able from + 5V to "do" + 3.3V. Of course it is possible to depict this point and on the linear regulator AMS1117-33, but the use of a converter it has a major advantage - it will not be heated. I must say that AMS1117-33 and also will not be much to warm up, as the current food matrices usually do not exceed 0.5A, but, I repeat, DC-DC reliable. Here's how it will look like the connection:
Attached Image

I hope the arrows are all clear: remove the diodes and connect the converter module. You only need to connect the earth (there are two of them on the converter and they are connected) and if you take it in the indicated place it is not quite convenient, you can take it where it is more spacious, for example, near the USB connector, there are already 4 large penny weights. The board itself can be glued onto a double-sided adhesive base somewhere close up. And I hope that is clear:IT IS NECESSARY TO EXIST A CONVERTER BATTERY VOLTAGE AT THE OUTPUT + 3.3V TO (!!!) HOW TO CONNECT THE MATRIX . You can directly "in the air" if you do not want to look for any kind of load, but it is better still on the load (a light bulb from a flashlight, a resistor of 100 Ohms and the like).
The photo shows the convertermini 360which is sold in China for about 20 rubles, however, this is the case when you buy 5-10 pieces, one of course will be more expensive. You can buy from us, but it will be even more expensive.
And this is how, for example, ready-made linear stabilizers look like on AMS1117-33:

They cost about the same as mini360. So, rather, this is an idea for those who have this chip in their possession.
I want to note that about this refinement a small discussion has flared up between supporters and opponents. Then everything settled down, butherenew victim ... AhereI showed the simulation process in kind.
As an option - placing AMS1117-33 on the "belly" of the board (3663) fromMarrakota here .

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

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

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

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

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

Attached Image

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

As I said above (under the spoiler about the controllers), plugs for connecting notebook matrices often have a tap to the backlight control connector (if the cable is of this configuration and under the corresponding matrix). In it, the output of the backlight brightness control is usually connected to the backlight output. And if you plan to connect the matrix to the controller V29, V39, V56 or V59, you will have to separate this wire and make a separate contact in the correct pin connector.
And finally, about rare special adapters.
Under spoiler above the first mentioned array of monitors with RSDS interface. Interface is a rare, but it happens that the dissection of a monitor can wait for just such a surprise. They across 17, 19, 22 inches. This interface can be called "unsupportable", since in addition to his native lane monitor connected to nothing happens. However, the Chinese have succeeded here. They made a special adapter for this purpose. There are versions of these adapters under RSDS interfaces any "pins" that exist in nature. they look like this:
Attached Image

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

BUTherehis description (many thanksluckylamer ).
Personally, I have never tried such an adapter, but there are positive examples of the implementation of projects with it by the forum users (see the spoiler of finished projects).
Shopping on Taobao first adapter can search by tag or LVDS 转 RSDS, or on the name of the matrix, and the second tag 120HZ 转接 板. In the picture the two connectors in the direction of T-con written as 45 and 55 pin - it's a typo in the T-con connectors 51 and 41 and just want to warn that the prices of these two adapters is very sensitive "bite" - are the first in the area $ 15, and the second - in the neighborhood of $ 35. And here's how to search for these adapters to Aliekspress or E-Bay - I'm not ready to say. I cite one example embodiment, the second adapter on Aliekspress. Here are just a tag to search for ... See for yourself

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

In the picture you can read an approximate list of matrices with eDP interface that can be engraved with the help of such an adapter. This is done a little difficult (the choice of a variety of jumpers on it), but nevertheless its existence is an irrefutable fact. Find this is only possible in China, a tag for searching LVDS 转 eDP 万能 驱动 板 or LVDS 转 EDP 转接 板. The cost of such an adapter in a circle with delivery of about 15 dollars.
Since this topic was written a long time ago, during its existence there was a need in another quite peculiar adapter - with a simple interface (input) Full HD LVDS 2ch 8 bit in the output interface V-by-One, because they raise similar matrices other way in foreseeable space is no more (well, perhaps except for the search options on the entrails of broken TVs with such matrices). Thanks to our Chinese friends that the adapter is also now available. Here is a screen rather than a link. To search AE try to find themselves by variations of the phrases "LVDS V-by-One".

I will separately dwell on one more kind of loops - a loop for connecting the matrixes with LVDS connectors on modern motherboards. Here the situation is quite deplorable - a complex connector is installed on the motherboards (namely, modern ones, starting with atoms 2800) and finding a suitable “tail” for it is quite difficult. I gathered all the informationhere.
To conclude this section, I would like to link to one interesting shop. I understand that this is not quite right and maybe not even quite acceptable. But because the adapter - something very specific and to find the right - not an easy task. Even on such a large trading floor as Aliexpress to find the right very, very difficult (primarily due to the lack of a proper description of the part of sellers), but in this store collected quite an impressive collection of almost all occasions. Perhaps the simple loops where you can find even cheaper, but find many adapters almost nowhere. And most importantly - the seller is very well versed in any subject and can advise on issues connecting any matrix, and offer everything that is needed.Here ishe. How long it will exist is unknown, but the makings of a long existence seems to be there.
BUTherea reference to a major Chinese manufacturer of the overwhelming amount of all the above iron. Perhaps it will be useful to clarify any technical characteristics. In the left column, select the subject of adapters and see what is in nature.

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

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

mini-LVDS - what the ... and how to deal with it
I think it will not be superfluous to focus attention on one more “variation” of the LVDS interface - mini-LVDS. This "beast" is found in the vast majority of matrices and there is no standardization of it for pinout. And of course there is no guarantee in matching the pinouts not only between different manufacturers, but even from the same manufacturer in different model series of matrices. What is it, let's try to figure it out ...
So, when you look at any matrix you can see the charge timing controller (t-con). They are equipped with the vast majority of matrices. Its purpose - to decrypt LVDS signals and transfer into the glass matrix of all necessary for its operation: signals for the formation of the image and the overhead to operate the driver both horizontally and vertically. In the early years of television matrices that node has a separate performance and can be be removed as a separate payment. If it carefully considered, it is seen that the input of the t-con is supplied LVDS signal, and to output terminals (there may be 1, 2 or 4) are connected by loops matrix glass strips. These loops and are thus interface mini-LVDS. First of all - this is not "relative" the LVDS, or rather, so distant that you can safely say that they are not related. There are TVs in which t-con as a separate unit and is not located on the motherboard main board. In this case, the matrix glass strips on maynbord are two loops. But our task - to remove from the TV "faulty" lane and connect the matrix to the universal controller. And he, in turn, the output only have LVDS. How to be in this case? It's not so difficult. The fact is that (for example) matrix LG-Philips audio line could be in several versions: with 4-channel 10-bit LVDS interface with 2-channel 8- or 10-bit LVDS interface and the mini-LVDS interface. What is meant by the words "one line" - but the fact that in all three at the same time issued by the type of matrix used the same glass, only added to one or the other t-con or it does not exist in cases where the t-con smeared on the lane. So, if you have a matrix interface mini-LVDS - enough to buy a separate card t-con, but not necessarily compatible with this matrix. It sounds a little scary, but in fact it is not very big problem. The main thing - do not make the wrong choice.
So, an approximate algorithm for finding a suitable timing controller.
1. In the matrices of one manufacturer (for example LG-Philips) different diagonals may be one and the same T-con. Those. Tkon on the board can be written such as 47 inches, and this fee can be in the matrices from 32 to 55 inches. It should not have anyone to strain. But this I know for some examples of this manufacturer. According to Sharpe traced this trend, but the coincidence is much smaller. According to Samsung - I have no such information. According to the IQ range is very extensive and I am not engaged in statistics.
2. In the names of the LGP matrices everything is quite transparent and understandable - first there is a diagonal number, and then three letters:
- first: W represents the execution with fluorescent illumination, D or E - LED where D - direct LED, E - edge LED
- second: U stands for full HD resolution, X is HD Ready
- third: N, Y, E, G, D, S, F, H. L is precisely defines the interface and then reaching suffixes (e.g. SB A1, PE F1, etc.) generally determine the already backlight organization. Moreover, the matrices with fluorescent backlit list of suffixes small - usually no more than SA, SB, SC. This is due to a small selection of design options for lamps. In LED suffixes much more, because LED lights can be as an independent with the use of a part of the matrix is ​​also ready drivers, as well as separately derived LEDs with different schemes of their association. I must say that this is just a result of observations and not official information from the factory. Plus another period is set to release some or other matrices. But the vast majority still can look through the datasheets on WUN matrix, WUY, WUF, EUH, EUF, etc. and make for a conclusion on what to look for Tkon.
How to search. Beat in the search engine "is the name of the matrix" and the word "t-con". You will see a lot of information about the sale of Tkon on this matrix - there and find the exact name of the board. Then the Internet is enough to find the pictures in a folder on certain boards Tkon, consult with the type of interface LVDS (recall that for the universal controller needs 8-bit 2-channel full HD (it is generally one connector 51 pin). Then you need to look at the organization output mini-LVDS, primarily the number of output terminals and the number of pins. it is clear that the glass 2 * 60 pin can not pick Tkon with a yield of 2 * 50 pin and vice versa. After selecting potential candidates need to have a look at the board Tkon organization pins in connectors mini-LVDS. at least start with a mass of conclusions, gamma, etc. often, the board signed pyataks visible control points of the track connectors. in general, the process is nothing but a quest and quite exciting. by the way the die LGP there is one trick: it is possible to build on the last number in the t-con and try to add or subtract a unit - often in these glasses, t-con, which were developed at the same time for different inter Faith had "a nearby" factory numbering. In the end it's just an example of such "finds". With SHARP matrices such focus does not pass - it is necessary to look for a similar name (can be a difference in what the letters or versions - all must look more closely). Try.
As information about the miraculous “engraftment” of this kind is confirmed, I will post more accurate names of what I crossed with.
So far, absolutely accurate and confirmed information (from me personally) - Philips TV 32PFL3606 matrixmini LVDSLC320WUY (SC) (A1), sided t-con 6870C-0310C LC420WUN-SCA1. Also suitable 6870C-0310B and 6870C-0318B. However, there is one caveat - the t-con does not know how to flip the image 180 degrees (in the chip used in it is not such a regime). Those. "Normal" position matrix with this t-con - when loops and t-con above. If you want to place the cables from the bottom - just guided by the controller, which "can" flip the image. We are waiting for confirmation of another "healing" LC320EXE matrix (SD) (N6) - as will be positive - I have supplemented ...
Here isFor example, what I mentioned above - the matrix LC420EUF_FEP1 has tcon 6870C-0402C (51 + 41 pins, 4 channels of 8 / 10bit LVDS). A t-con 6870C-0401B (51 pin, 2 8-bit channels) from the LC420EUE_SEF1 matrix is ​​installed on its glass (it is the same in LC370EUE_SEM1). Everything worked and did not have to use the adapter, but only changed the t-con. thank_LennY_ .
Unfortunately, in the matrices of the last years of release, more and more often t-con is made non-removable - it is cut into glass with COF loops. And of course, there can be no question of its replacement.

Recommendation. As a rule the fantasy of many "diy" further than the increased radiator and planted it fine Karlsson, which blows in the radiator, do not go. However, this is not an effective method of dealing with the heat. There is another way of cooling the main chip (also much more efficient) fan put not on the chip heatsink, and case-back exactly in front of the radiator. What this achieves: blurred requirements to the diameter of the fan - in fact it really is not necessary to pile up on the board, plus (usually) the larger the diameter of the cooler - the lower its speed (respectively - he quietly works). What has the fan should be placed so that it is "pulled" air from the radiator. Thus cooling and becomes much more efficient (in my personal testing) is sufficiently regular controller radiator. But there is one condition - the fan should be located as close as possible to the radiator. If the rear cover is not structurally allows you to bring the fan to the radiator, can be put on a ventilator likeness "pipe" as many were able to observe the example of computer cases (where there is a pipe that when the cover is approaching close to the processor fan on the side of the cover). To make such a duct is easy enough to unnecessary from the blister pack by something.
And finally, the "bike" from me.
I have to get hot water at home hanging column. "Fashion", with electronics and pokazometrom temperature. When should the temperature of 45 degrees, a feeling that can scald your hands. If you put a 50 - all tin. What am I ... the normal operating temperature reaches 60-70 degrees to the silicon crystal. So make your conclusions. Chip room temperature no guarantee and cooling - this is more for your peace of mind. It is very possible that the natural convection (if present in your body) is quite enough.

All about consoles
At first glance, it seems that the controllers are so "universal" that even the consoles are the same, but this is not quite the case.
HereOne forum user made a short photo report on the remotes and described their compatibility and interchangeability. This question caused a whole storm in the discussions until all versions of the remote controls were revealed. It turned out that the question is very delicate and serious. Comparison of command codes dotted i.HerePhoto of the "correct" remote control for the controller zvst3463, the same command codes. BUThereto compare remote control command codes from other controllers.Herecommand table from the "semi-correct" console from ZVST3463.

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

I do not know for what purpose 8 buttons were originally conceived. With high probability, the Options button will not work at all. On the right (in the picture) I changed the scheme for 7 buttons.
Implementation scheme of buttons for two-wire controller is shown for RR52C.81Ahere.
There is another "theme" - in the fresh controllers, the function of reassigning buttons is increasingly beginning to appear in the service menu. I personally have not tried it, but I know for sure what is in QT526 and in RR52C.81A.Tyk. TSUMV56RUU-Z1 is also mentioned there. But in any case, with the initial firmware, the order of the buttons will be as stated above. And if you reassigned as you like and conceived to reflash with some other firmware, you will have to restore everything again.
indication LEDs are connected each to its pin connector red - to LED_R, green - to LED_G. You can apply as a three-terminal two-color LED and two separate. The main thing - to contacts LED_R and LED_G connector connected anode (!!!) LEDs, and the cathode (at the three-terminal) or the cathode (in particular) - to ground. Inscription R and G does not mean that it is necessary to use only the red and green colors - but at least some. If you modify the unit has light-emitting diodes (usually there are white) highlight the brand logo (available in many televisions, especially in recent years were extensively applied in Chinese "brand") - I would recommend to connect it them to contact "LED_G" - will be super. ..
Sometimes, in the final design (which acts as a donor for homemade) there is only one LED and a second room for oneself is not just difficult, and sometimes impossible. For example, when the LED in SMD form factor and some do not stick anything, and besides, still and there is no free contacts in the connector bar. Then you can use the two diodes "build" lines LED_R and LED_G one (diode-Live on each line connected to the cathodes at one point) and this is the only line is applied to one LED. Then it will work in conditions close to the standard to modify the unit, ie, in sleep mode illuminates the work - lights, and based on a command from the remote control - flashing. However, experience has shown that even only one "red" LEDs and no unions in line. ATby thisI applied only one LED to my project, connected it to the "red" contacts and still do not feel inconvenience - it alone suffices. It glows in sleep mode, when the TV is on, it does not glow and blinks when commanded from the console. As you can see, there is no need for a second color at all.
As for the photo receiver eye, download the manual to any controller and there you will see the simplest scheme for assembly. By the way, in all TVs the “native” photo-eye is assembled according to the exact same scheme, well, maybe there are some minor differences, but it connects the same way. The type of photodetector (it is not listed there) is VS1836B (the real "branded" eye from Vishay is called TSOP1836 or TSOP1838). Contacts on the universal controller connector, to which the eye is connected, are also indicated in all manuals.
By the way, one more thing (for those who are not “in the tank” at all): there are only two “masses” on this connector and if you pull the buttons separately (and they “work” with respect to the mass), the LEDs are separate and the peephole is separate then one more mass contact is not enough. It is only necessary to "branch out" any of the existing "masses" with two wires.

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

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

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

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

What can I say ... It works too. It costs about 350-450 rubles. However (!!!) in comparison with the previous version, it still need an HDMI cable to connect. As if the thing is not expensive, but nevertheless. The pictures can be seen that this box has a mini-USB power input, but it works quite confidently and without food - it is taken from the HDMI line and missing. The sound is the same as in the previous example. If someone needs a higher quality sound option - there is a box with the passage of HDMI and audio branch to coax, SPDIF and jack. They cost more - at 700 rubles. And, believe me, are working well, so I put someone to connect acoustics.

But no matter how "honey" may be the solution, there is in it and fly in the ointment: the sound of the piece of iron with removable, for a split second ahead of the final image. I compared both the TV and the connected computer speakers - turns out not even as a little echo, but rather perceptible repetition. So that nothing is perfect. While watching what content to view. Foreign films with translation, music, porn: D, cartoons, and many Soviet films do not suffer from this. Perfectionist notice it in what ever live with a close-up.
In China sold more and more "civilized" box for this purpose. Possible (!!!) that they have taken into account this is a misunderstanding. And they are from 1200 and higher, up to 4000 rubles. But where is the guarantee that he gave the dray amount we do not receive the same as for 300 rubles? That's it ... In the meantime, study the subject adjustable audio delay. They say everything can be done on a single chip from Holtek, vosminozhka with minimal strapping. If that dig - add ...
Yes, I hasten to announce yet another hypothesis: I confess, I have experienced on your Philips TV, and even smart. Bearing in mind what is the brake, there is an assumption that the processing of HDMI video monitor is faster than the TVs, and maybe a difference with the sound ahead of the monitor just will not. While checking on anything, but I believe in success. Then I report back ...

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

I deliberately provided a picture, not a link, because the product can end, but you can always find it on Alibaba by the picture and the "3 to 1 HDMI" tag.
What is "automatic": the switch itself is switched to the entrance, where there was a HDMI signal. Moreover, if the input signal which is already present and the switch is turned on to it, then when the signal at the other input switch is switched to the newly appearing signal. After disconnecting switch returns to the previous input. It feeds on the switch or from the + 5V (for example, from a free USB output from the adapter to charge any modern smartphone), or any of the HDMI input (the strings that are inserted into the HDMI sources).

Radio elements on controller boards and their replacement
Under this spoiler, I will add proven options for replacing radio components on controller boards as I am.
1. About the audio chip CS37AD2AB and its replacement informationhere.
BUThereone more experience fussing with this frail microcircuit. I think now the controller's MIND will only become more reliable and certainly not worse.
2. Chip DC-DC down converter. Many boards are rated for 1.2 and 1.8 volts. Small, 5-legged, in the case of SOT23-5. The designation AAAA, AAAAB, AS11D is found. Known replacementMT3410L, SY8008or AUR9703tyk.
3. MOSFET key, which is installed on almost all controllers as a matrix power key and a secondary power key. Mostly found with WSA6L, WSA6S. The correct name is LCS68P03. According to the datasheet, the designation is WSA, and the remaining digits are the date, batch, etc.
Attached fileLCS68P03-2.pdf(504.82 KB)
It changes to absolutely any p-channel MOSFET key with similar parameters. Of the names (accurately known), AO3401 was checked (the cost per unit size was 6-7 rubles), of the markings, B052 was checked (unknown name). What else I learn - I will add.
4. Integrated circuit DC-DC converter 12B-5B, octopus (SOP8), denoted 5 DABAD type letters, DAAAB and in this way. On AE is sold under the names L6562A, L6562AD, which is clearly not true. Wherein "draw"Is clearly what is needed is therefore 100% guarantee is difficult to be more precise, do not give offer its own version replacement of this chip, which is certainly easier to get -.... MP1583 This option is ideal for use with low-power matrix controller If the use of the controller is assumed. with a 12-volt matrix, it is possible to apply and MP1410 (2 amp converter) or MP1483 (3 amp). it is also possible to use TPS54329E. But in the proposed me embodiments, the output divider unfortunately denominations may differ from that which is mounted on circuit board . universal controller circuit of the DC-DC converter is as follows:
Attached Image
So the output voltage (in our case it 5B) is set by resistors R1 and R2. But every chip they have to be "their". in datasheet write how to pick them. Therefore, all of the above options for replacing alas involve the selection of the two resistors. But in a desperate situation and it is - a way out.
Another option to get out of the situation without any attempts - to pull off Gorelov chip and instead pick up a micro-module, mentioned under the spoiler on the recast of the power matrix - 360mini, putting its output of + 5V. And not necessarily fluster wiring from it exactly into place tabs chips: Input 12V to charge the power connector, the output from the module to connect to any throttle output (from strapping chips) and mass - at any convenient place. A micromodule can locate itself at any cooled surface to be near (for example on the back of the matrix) certainly applying necessary measures Circuit feed points to ground. Of course, if you expect a matrix with a large current in the power consumption (eg with diagonals of 26 inches or more and a 5V supply) - to apply a more powerful unit, for example LM2596, which is designed for a load 3-4A. Big matrix with 12V power is not applied to any selection criteria module, and then of course quite 360mini, because the module is in this case only feeds the controller itself, and not die.
And finally.Hereone good man laid Changhong TV circuit in the MCU MSD3663. It is clear that it is not 100% D3663LUA controller scheme, but a lot of moments where you can learn - MCU strap, tuner, power supply circuit core, keys and stabilizers. Pretty much the same. So the name of radio can be found there.

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

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

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

Questions about programming controllers
So, friends, this section is dictated by the ever-expanding circle of "friends" of this topic and more and more often emerging issues on the most difficult - the process of firmware controllers. The process of firmware controllers varies depending on the type of iron. And before starting, I have to explain something in order not to be confused in the future by those for whom this topic is new.
So, on different boards set the MCU controllers (this is the main chip - Micro Controller Unit) of various "intelligence" (I am sorry, but I'm so easy to express the idea). Those. a controller for the monitor does not need "brains" of the controller with a TV and a media player. It was simply to shooting from a gun on sparrows. And, since the latter are distinguished by the presence of the USB port, then the firmware process is maximally simplified - everyone knows how to program any controller with a TV on board. Another thing - the controller firmware process that does not have such a wonderful function. And it's quite a long list of models that do not have USB ports. What then? Again, a little literacy ...
Aza ... The boards all controllers memory chips that store the algorithm of the entire controller, and variables that MCU controller writes back in service. Variables - a variety of modes, settings, scanned and stored channels (in the case of controllers with TV), as well as a set of adjustments and selected levels of inputs. Any change in the status of the controller is accompanied by a recording of this state in the memory chip. Accordingly, if, after an action of reading a memory dump and synchronize it with the previous - dumps will be different. Since the 2000s, virtually 100% controller models have been used so-called memory chips "25 series". The number "25" is present in the name of all the manufacturers of these chips. For example W25X40, M25P40, 25LV040, AT25DF041, SST25VF040 - only different names of the same chip, depending on the manufacturer. In the world of 25 series - the so called SPI flash. Those. memory chip, which exchanges with the periphery of SPI protocol. So, if you take up this chip (chip only, not the controller), and flash conceive it, then, for this we need a programmer for the chips that it will sew it on the SPI protocol, and in no other way. However, this way of course may not be convenient for controller manufacturers. Due to the fact that the MCU controller also interacts with this chip on the SPI protocol, MCU manufacturers the opportunity to lay the SPI flash of flash on the other widely used protocols - I2C, but software MCU itself. Those. we take a programmer that works on I2C, connect it to the MCU on the DDC channel through the VGA connector and safely sewn SPI FORCES of flash controller as a programmer interacts with the MCU on the I2C, and the MCU protocol, in turn, communicates with a memory chip on the SPI protocol. What it does not need to unsolder the memory chip to its flash. Yes, sometimes it helps just desoldering and direct programming, but often enough to be sewn over I2C. What is it about slot VGA, you ask? If you look pinout VGA, you will see that in its composition has SDA and SCL bus, which are the basic I2C protocol. But as part of the HDMI connector also have these two tires! En, not - for programming the controller, they are not involved, only the VGA (and it's not a fad proshivkopisateley - it is an unwritten rule MCU manufacturers). And in the controllers that do not have a VGA input, this tire displayed on a special connector is for firmware.
For what I wrote all this. So that there is no confusion in what and with what programmer it is stitched and the most important thing is how it is stitched.
By the way, television controllers in addition to USB can also be flashed via the I2C protocol via the VGA connector. Moreover, in comparison with the standard method (via USB port), this method is "low-level". Those. they can even “raise” a contorted controller. The reason is simple - this way of flashing, in simple terms, occurs at the hardware level.Here ispositive experience fromRxmaxx .
Well, now closer to the subject.
So, we have on hand controller. What we need to be sewn over the I2C bus? Just nothing - we need software that "understands" what exactly is a chip and how and what to pack in a protocol to the MCU "gave the green light" to the firmware SPI Flash and adapter to connect the computer to the controller (popularly called "jig" on English Jig). Oddly enough, but to find and install software - very simple. But Adapters ... Release of each chip is accompanied by the mandatory software for its programming. As the change of the software is improved chip generations, it adds new libraries to support the newly produced chips and support available interfaces on the computer. Nevertheless, he is tied to circuit design software adapter, which is stitched using the controller. But here again we have a great stalking "ambush." The fact that the easiest (shemotehnicheskogo) adapter can only be to the LPT port. And even though the do it yourself will result in costs of about $ 2, "branded" jigs are sold in China for $ 15-20:
Attached Image

But LPT port already "outlived" several generations of computers back. What is the reason you ask? And the fact that the programmer - is a harsh piece of iron, and he does not need "thingies" of Win7 ... 10, and designs just spinning on Embedded versions of WinXP. Strange to say, but most of the software listed above is not intended to work with a serial COM-port (even with him the situation is still much easier than with LPT) and, accordingly, no such jig. Although, it is not so, I do not say so little. I mean, I never met a single ISP programmer for COM-port of any sale of, or even mention of this, but they say they exist.Here(on the second page of the topic) such is mentioned, and even theoretically would approach our controllers (as it is under Mstar), but in the same place they write that it does not work ...
As a result, of the "modern" is only a USB port. Although, the most interesting thing is that it is also serial and USB jig is usually a hardware emulator of a COM port. However, industrial USB Jig costs around $ 50, and self-made ones are associated with relatively complex circuit solutions.
All of the above allows for many to make a disappointing conclusion - the firmware of the controller is very complicated, troublesome, and in some cases costly. However, not everything is so sad.
Above, I mentioned that the memory chip can be flashed directly using the SPI protocol if it is dropped. Immediately the question: what and how to sew? For this, the Chinese programmer is very well suitedCH341A(look for Alibaba on the same tag). Its cost is low - within $ 2. With the software, problems are possible for him, however, there are a lot of developments on working with this programmer and you will find everything you need (for our theme)herethank you so muchNewview . True, there is one nuance - the chip should be dispensed. Newview mentioned in his message "clothespins". This is a special cable-adapter with clips, which clings to the legs of the chip like a clothespin. TO DO NOT REMOVE IT. This cable helps in many cases, but with respect to the controllers I have great skepticism about it. To make it clearer, here are two schemes:
Attached Image

Programmer picks through the clothespin to the chip and the SPI Flash, turn on the POWER. Now think about it: if a dead pull the programming station circuit in the second picture when the MCU current consumption is 500mA? There's your problem. If someone says that, they say, "CH341 does not sew through the clothespin from the fact that it is of poor quality," you know what the answer would be - the programmer simply pulling the controller nutrition. If anyone says that I have thought up - grab a controller on RTD2662 and twist it in his hands. It is made exactly the right pattern, and consume 350-400mA order.
And now, when you are familiar with the theory, it remains only to give references to software and bring jig diagrams.

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

Compared with the jig for Postal2, there are noticeable differences in connection with the parallel port. I suspect that all other branded jigs are built in the same way, and this is the reason why the jig from Postal2 did not work with Device Well MCU Isp Tools. This is not a fact. I did not check (because I still need to collect this jig, but I don’t see the point, as I need Postal2).
Here isAn example of a simple jig on 74HC05 for firmware and realtecs and novets, but for some reason it costs like a diesel locomotive.
... That's why I solder them myself !!!
A little later, I will collect the programs themselves, which I have available and lay them out here. True, you can download them yourself through any search engine - they are not a shortage.
As I said, the controller firmware is carried out through the VGA port. Well, since there is an I2C bus (for firmware !!!), then bright, minds find other, alternative ways to flash through this bus.Heredetailed manual fromNewview on programming the controller (Realtek RTD2660) with the help of Arduino. Why not?
Here isdescription of the process of programming RTD2660 controllers based on Arduino NANO or Arduino PRO MICRO fromremizov_ia .
well andhereprogramming method based on the same Postal2, but without the LPT port, but only with the help of cheap and affordable CH341A. The only thing - maybe on different controllers something differently, but nevertheless on another site ransuchamendment. Anyway, the main thing - the way it works ...
As mentioned above, the Novatek Easy Writer program is required to program the M.NT68676-2A controllers. But the program itself is not even the floor of the case, it is freely available. The main thing - the jig and ports. But with this a little tight. Since this controller is not at all rare and is used from time to time by our comrades, it is also necessary to program it as well, that is, there are two ways:
1. purchase a regular programming kit for it (which is, you see, absolutely no ice ...)
2. Independently prepare a dump and pour it into SPI Flash yourself.
The meaning of the dump preparation procedure:
- take the necessary firmware (they are in .hex format) and roll it into .bin
- copy all the firmware and paste it into the end. Those. double array Save to binary.
- Pour this binary into the flash.

I put just in case Novatek Easy Writer. Even two distributions because the program a little bit moody to iron and sometimes necessary choice:

What is EDID
1. EDID is first of all data. Hence it is "they." However, it is not always convenient to write like this - so do not scold if it is in the singular masculine.
Let's try to figure out what it is and why you need. First of all the contents of this data is for the graphics card (video card). This block of data (firmware any controller) of 128 bytes, to which the "drawn" card for information about what a controller and what permissions can be granted to it at its output. Each interface (VGA, DVI, HDMI or eDP) has SDA and SCL bus - i.e. i2C components of the tire. Firmware (as mentioned in the previous spoiler) "charges" controller chip memory (SPI Flash) with all the necessary information to the controller. Including EDID blocks - they are in a certain specific memory address space. Bus SDA and SCL with the connectors go into the MCU. According to him refers to the MCU card, he gives her the data from EDID block card it receives a response and "decides" what permissions can be offered. The word "offer" means the procedure for selecting the resolution in the properties of the graphics card - go and see what permits are available. It is this list of available permissions and "dictated" the video card EDID block. For each of these interfaces in the firmware contains a block of EDID. Those. If the controller has two (such as VGA and HDMI) or three inputs (VGA, DVI and HDMI), then for each of them has its own block of EDID.
2. The notebook is about the same situation, but the physics of the process is different. There are applied the matrix as part of the interface which has its own bus i2C, and inside there is the matrix chip (EEPROM, 24 series), in which only a single stitched unit EDID. More there is nothing, only this block. In this section there is information only about the native resolution of the matrix and no other. Laptop graphics card also takes information on the I2C bus directly from the chip matrix and the matrix outputs with the image data obtained: resolution and timings. Why so, you ask? To understand this, it will have to use your imagination. help:
3. Do any of the matrix is ​​the concept of "pixels" - a point that is formed of the three color components. When we say "permission" - this is the maximum possible number of display dots horizontally and vertically for a particular matrix. Pixel - a "physical" point of the matrix. Those. if to light (or darken) one pixel on the screen we see a point with well-rounded edges. Those. if the matrix has a resolution such as 1280 * 1024, it literally tells us that the horizontal matrix can display 1280 pixels and vertically - 1024. Now, imagine that we are trying to apply to the matrix signal with a resolution of 1024 * 768 ( hypothetically, of course). In this case, one signal point of the feed at the geometric dimension is larger than the physical point matrix both horizontally and vertically. What we see: so what to display such a point will be used for 4 physical pixel matrix. But it served the signal is not a multiple integer of the resolution matrix - hence the picture will be highly distorted. Based on this example, one can easily conclude that the most accurate and high-quality image can be obtained only by filing a matrix with a resolution of the signal, corresponding exactly to resolve it. In this case, it does not matter, the high resolution of the matrix or low,the clearest picture will be obtained only with such a correspondence . Only the size of one pixel depends on the resolution of the matrix and its diagonal. I hope this is clear.
Go back to start to the second point. So, the laptop's video card reads data from the matrix and gives the same resolution. This is not surprising - in a laptop there is only one matrix and it works only with it. So the choice of the graphics adapter parameters will be a single resolution equal to the resolution of the matrix. There will be no others in this choice.
Now closer to the subject. Since we have a controller and have some sort of matrix, that have to work together. But the connection diagram here already do not like in laptops - the matrix is ​​connected to the controller output, and digital and analog interfaces - to the entrance. As I said above, by filling the right (for this matrix) firmware controller should work correctly with the input signals. From the previous paragraph you have to understand that the best has to be the input signal with the same resolution as the matrix. In this case, used such a thing as a "native resolution." But the video card needs to know the native resolution of the ligament Controller + matrix! So to work correctly on the video input in the firmware must be EDID block for this entry, in which contains information about the native resolution. But there is another point: because the controller with the matrix from a computer point of view - is nothing but a monitor. And for all the monitors tend to have a certain set of supported resolutions on the board to graphics adapter in your computer "could" navigate to them. What is meant. The best resolution for the monitor - it is clear, it is native. In blocks EDID (I forgot to say - they are decrypted using special editors) this is called detailed timings (still happens native or preferred timings). All other resolutions supported by the monitor, called established and standard timings. For what they are necessary at all: at OS boot time on the screen are different stages - POST, BIOS, welcome screens, and finally himself OS interface. They all have different resolution and refresh rate. To monitor displays all these stages, the graphics adapter "looks" in the list of supported resolutions in the presence of the desired image display. If desired not, it will be either a black screen, or near the resolution included. It all depends on the graphics adapter manufacturer MP and bios, as well as the capabilities of the monitor scaler circuitry. All of the above necessarily refers to "computer" interface (eg VGA and DVI). And this is where all the "bound" can be scattered by bad faith proshivkopisateley. If older models of controllers, it was all right, the modern seems there are such disadvantages. The reason is simple - the first controllers were "brainchild" of the capitalist Chinese (Taiwan), and have been very carefully worked out, and the last - already rivet in socialist China, and already with a touch of Chinese "maybe".
4. And what about on the HDMI input? But with him no longer so simple. The thing is that HDMI - Multimedia Interface, and initially calculated on the use of video technology. Since the HDMI digital interface - and then he began to be used in digital televisions, ie Standards HD Ready (1280 * 720 initially, and later in 1366 * 768) and FullHD (1920 * 1080). "Television" language - a resolution 720p and 1080i, 1080p. The vast majority of all extender revolve on the issue of these two resolutions. Now back to the EDID. It is easy to understand when it comes to the graphics card, then of course - is a computer in any form (whether desktop, tablet, some of my Linux mediadevaysy etc.). Those. those machines in which the card can issue any resolution on the HDMI output. But the receivers, set-top boxes, media players budget is not designed for what is arbitrary values ​​- they just also are present only 2-4 standard TV resolution. Why am I saying this: the fact that over the EDID HDMI inputs is practically no one has ever worked as carefully as for VGA and DVI. Those. in EDID HDMI data, at best, it contains usually only a couple of permits HD Ready and Full HD. To connect any mediapristavok that is enough. But by the connected computer has a big problem. Well, if the controller is connected to the matrix HD Ready or Full HD - in this case, the choice of parameters, the graphics card will be visible, and both of you can select the desired (native). Then everything will be fine. But if there is a matrix that does not fall under both of these, then there is the following picture:
Suppose that we have the matrix of 1280 * 1024. From HDMI input card controller sees the ability to run any HD Ready, or Full HD. it does not offer other solutions. Choosing a lower (e.g. 1280 * 720). In this case, both permits (computer and matrix) of equal dimension horizontally. So horizontal resolution will be fine. But vertical scaler controller 720 lines "smear" the 1024 rows of the matrix, i.e., One point vertically into the matrix 2 will be marred physical pixel. That will have a "soap" in the vertical and nothing can be done. If the computer sees in EDID resolution is 1280 * 720 and 1366 * 768 (which may well be), then the overall picture will be even worse. If you select the graphics card resolution of 1920 * 1080 - also nothing good happens. What it tells us - only that the HDMI input on the universal controllers in many cases unsuitable for the use of such a controller as a PC monitor.
5. To deal with shortcomings in the firmware can be, but alas, only controllers on chip Realtek. The cap is threads controllers on chip RTD2662, RTD2660. The fact that the firmware Realtekov EDID blocks are present in an explicit form. They are easy to read, how to edit (of course if you know how, anyone should - ask questions), and re-introduced into the firmware. And then the HDMI input adequately fulfills all the functions of the monitor at any desired resolution. As for Mediatek (it all controllers with TV) - alas, get EDID block of them is not possible, as no firmware or dump it in the clear no - the MCU itself generates EDID of the firmware. Even if it were possible to read it, which could be corrected then pour EDID? How to decode the case - there is no such information - and there is nothing to correct accordingly. All hope is only for firmware, which is in the public domain. If you have something correctly - do not get corrected.
True, one bright mind (and maybe not even one, but two or three) here on the forum offered to work with EDID "crowbar". Those. stupidly cut a square bus i2C at the connector and hook up to the connector an EEPROM with the necessary EDID of the type as done in laptops. Those. in this case, the video card will not apply to the MCU, but to this microcircuit. I have not tried it, but why not?
There is another way - this is to force the video card to give the necessary resolution through force. But this method can be implemented not with every graphic adapter. I managed to get my Radeon HD 7350 to issue 800 * 480 for the controller, in the firmware of which there was no EDID block at all. But with the NM10 graphics on the "atomic" motherboard, such a trick did not work.

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

I will try to pick up the matrix n070icg-ld1 to the board on V59
The matrices N070ICG-LD1 there are some nuances. At first they went two audits. LD1 old came with a 39-pin DIL connector (which contacts are staggered), new - 40-pin single row. For DS old LD1 "is able" to work on the 6 and 8 bits, the new - only 6 bits. After some time, the new N070ICG-LD1 renamed N070ICG-LD4. Datasheets it is not. The pin - LH take on LD1 (39-pin) and increase its number of pins on one - get the pinout LD4. And of course there is no pair RXO3 SELB absent.

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

Went here to see what you can do with the old tablet;) and then how even it became interesting.
I will continue, from the laptop, the cable has pinched 40 pins and into the matrix, it stood up normally and it seems to hold, I'll probably order the cable from the Chinese, it's all easier than to solder the cable itself.

What is it about?

Definitely. In addition, it is inexpensive - before the trains were under a thousand ...

About entom. I understand the backlight power here, too, in the train? And the V29 will not start there ?? Need to shake up the train. That point, I'm afraid to burn.
In my life, I burned a lot of things, and I did and repaired - a lot, But it turns out to be repaired, when you understand what you are doing, until you catch up .... Once there was such a "shaking" when I started to deal with computers (there are no circuits , there is no guidebook, a bunch of microcircuits, there is no one to explain), then I realized that everything is simple, but from the beginning there was a jitter. But then the hands did not shake, the vision was 100% ...

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

* Boris-leo, FROM THAT THAT WAS WRITT, I DON'T UNDERSTAND ANYTHING;), On the matrix board there are 2 wires - red and black. Go to the matrix controller.

From there on the FIX30, right? Is that a highlight? Or is there a controller "Invertor" connector on the matrix board? In short - I'm stupid ...: girl_cray:
What is this cable? Not lvds?

And on my cable you need to leave only these wires, what's on the photo? If so, then I do not understand where to put the wires on the side of the black connector ....: sveta:

Began to make a table, for the help I will be grateful. (I took the name of the contacts from the Chinese site, It is desirable to correct them.)

Firstly, it is not very clear what matrix to connect. In the pictures in the previous message there is a 30-pin matrix (I used to give a link to the CLAA089NA0ACW datasheet — it has the same pinout), and in this table, for some reason, the 40-pin matrix.
And secondly, again about the previous message. I do not want to repeat again and again, it is easier to explain "on the fingers". We look at the picture and carefully read what I wrote there:

Ps. The number in the name FI-X30 means that the connector is 30-pin.

All the same, then it turns out that it has wires backlight?
If I understand you correctly (all the same, I will once again turn to my standard cable), should the matrix look like this?

Postings that stuck in it, marked with a cross, you need to pull out? Backlight then how will be regulated? Are backlight wiring marked with ovals needed all or can you leave only (+) and (-) one by one?
In general, if I understand you correctly, should it happen?

I apologize for perseverance. And another question;) On the reverse side, in the "mother", you do not need to rearrange anything, leave it as it is?
And a huge request, if possible by points: blush:

It is better to go all over again.
Pinout connector LVDS on all Chinese controllers. The first pin is indicated on the board by a triangle. The second - in the next row in front of him, etc.
The outputs of the TXO controller correspond to the inputs of the RXO matrix

Here's how it should turn out (did not show the "mass", but even so clearly):
