flash firmware onto a v56 lcd panel driver board factory

LCD panels of broken laptops or old TVs can easily be turned into multifunctional displays. You can give them analog and digital inputs and media player capabilities with a cheap universal controller board. As long as the panel itself is functional, you can use the V56 controller board to drive both the screen and the backlight. Reuse LCD screens as media players, video monitors or computer displays and save them from the garbage dump!

The easiest way to repurpose your LCD panel is by using a V56 controller kit that comes with all the parts that you need. I tested the V56 Universal LCD TV Controller Driver Board from Banggood It supports most LVDS panels with resolutions up to 1920 x 1080 pixels.  It comes with the following parts:

First of all, remove the LCD screen from its housing. In my case, it was an old laptop screen, so I detached the lid from the laptop and removed the plastic housing from the screen.

According to the specifications you looked up in the previous step, you need to set the voltage jumper on the controller board. There are 3 options: 3.3 volts, 5 volts and 12 volts. Make sure you set the right voltage, or else the magic smoke might escape!

Look for the file that matches your screen’s model number and resolution. If the model is not listed, then choose the “general” type for that resolution

The power LED should be blinking BLUE for a couple of times while it’s loading the new firmware. If it doesn’t upload the firmware, you should try renaming the file from “LAMV45R.bin” to “LAMV56.bin” (remove the R)

USB File Format: Audio (Mp3, wma, m4a/aac), Video (avi, mp4, ts/trp, mkv/mov, mpg, dat, vob, rm/rmvb),                                                 Picture (Jpg, jpeg, bmp, png), Text (text)

It continues to flash and never stop. This is normal, just wait about 1 minute, this means that the update is complete. Then turn off and turn off the u-disk

Download your required software and then extract it you will get the folder. Now copy the files to USB or load with Programmer. For More Detail about the download process, watch the video Click Here

However, this "new" V56, there is no support for most popular laptop"s screens, like for example: 1280x800_SI6L, 1600x900_DO6L , 1920x1080_DO6L and many more etc. etc. Anyway, there is way to made them work, for example for screen 1280x800_SI6L use firmware "1280x800" and "SI8L" and then, if still not working, in "Service Menu" change LVDS MAP value, that way screen works well as SI6L . The same can be done for other resolutions and LVDS signal types, as described

There are also signals that some new V56 controllers, rejects LAMV56.bin file and do not want to program it. In such case, add letter "R" in file name, like that - LAMV56R.bin, such file will be programmed well. This character "R" add for first time reprogramming only, after successful first time controller reprogram, you can use regular LAMV56.bin files without "R" for next screens.

So, always consider and think twice, before buy any board, choose seller fully supporting latest firmware files for his board, if he is not - simply DO NOT buy, because you will have useless piece of junk.

Programming is very simple, we must choose proper .bin file and copy it to USB pen-drive at root directory, plug pen-drive into USB, then plug power cord, status LED will made some flashes, first slower and at end faster, and software upgrade is done, you will see picture on LCD screen.

Attention: Sometimes, when playing with firmware, if there be power cut/brake during programming and flash will not finish programming, than the board become dead.

“PCB800099”, also known as VS-TY2662-V1 is an LCD controller PCB which has entered the market relatively recently. As per usual I have no idea who designed either the board or who wrote its software, but I do know it is based on the Realtek RTD2662 controller, although some may be labelled RTD2660 (which in theory means no HDMI), but if your HDMI input works, it’s an RTD2662. This is just sloppy chip labelling. The RTD266x family represents Realtek’s “TV” lineup, and using this, you notice it.

With my favourite variety (the RM5451 and variants) of D.I.Y. LCD controllers getting long in the tooth, and this also being a Realtek looks like a promising replacement, but having ordered one, I’m not quite sure it is.

It feels more like a TV, less like a Monitor. The RM5451’s firmware mostly manages to stay out of your way, whereas with PCB800099, it’s firmware is in your face. You’ll get a no input “Blue screen”, comprehensive and lengthy OSD popups warning of “No Signal” and whatever input it’s set to.

Because it’s a TV, it assumes that more than one input is in use at a time, and doesn’t auto detect, You’ve got to select the desired input. This is annoying when you’ve got it as a carry around rig using only one input at a time. At least once you a select an input, it remembers it even if you power it off. Thank god.

For the more advanced hacker (i.e. one who’s bought the programmer kit), it’s not as great. Unlike RM5451 which comes with a reliable USB programmer, with hundreds of images for various LCD panels, PCB800099 has only a parallel port programmer with just a handful of binary images, hacked by the vendor to to support a few panels. Some images don’t work at all.

But it’s not all bad. I’ve added support for PCB800099 to my ROVATool application, allowing a USB programmer (More here) which at least makes the programming of these boards a bit easier, but I don’t support editing.

The panel I used here (LP171WP4) is unsupported by the supplied images, but by picking one with the same resolution and LVDS interface type and modifying the embedded EDID blocks I was able to get it working.

It is connector compatible with R.RM5451, including the LVDS interface and backlight. Caveat: backlight enable signal is only driven to +3.3v, which in rare cases could cause issues. The LP171WP4 I’ve got it connected to is a rare example of this, where I’ve had to buffer it because it requires a +5V backlight enable signal.

Overall the hardware solution of the RTD266x is a clear improvement over the RTD2120L + RTD2545 combo of the RM5451/RM5251, but unfortunately in this case, unless you’re happy with the insides of a cheap TV, the same cannot be said for its firmware.

A reader has kindly posted a source snapshot on github (originally provided by another reader) of the firmware, including the changes needed to make it actually compile and program with ROVATool.

I get a lot of emails about this board to the effect of “I just bought one of these – how do I make it work with X?” If you’re thinking of sending one, please don’t. Trying to train up even a single newbie on this subject can burn hours of my day.

I am always keen to hear from people who have already been on the journey of learning about display controllers, and are at an advanced level of understanding, and perhaps even may have something to add to what I have here.

Note: Since the driver board model is updated frequently, the appearance and chip will be different, please refer to the actual received. If you mind this, please buy carefully.

1. This product is compatible with most models. Customers only need to confirm that the LCD screen is compatible with the following resolutions, without repeating the inquiry model. (Firmware burns the corresponding resolution)

2. This product needs to burn the firmware by yourself before it can be used. If you don"t know how to burn the firmware, unfortunately, it is recommended not to buy. Thank you for your understanding.

3. This kit comes with a 2ch 8bit 30pins screen cable by default. If it is not compatible with your screen, please purchase a matching screen cable separately.

4. Be sure to use the correct power supply. If the current is too low/too high, it will fail to boot, or even burn out the chip and damage the motherboard.Power Adapter: DC 12V 3-5A

Burning method: to record the screen program in the USB flash disk, USB flash disk inserted into board, plug in the keypad, electricity; About after a few seconds, press the keypad lights start alternating red and green flash, flash lights began to write programs (please do not power), light in the slow flash first, after a slow flash flash, will speed up the quick flash, long after the last until the lights stop flashing light is the program written, electricity burn with USB flash disk to complete the program.

Not only USB interface can be used to upgrade programs, but also can use to play video, basically formats are supported. You can also set a boot display pictures or LOGO

The original firmware collection for the V56 Universal LCD TV Controller Driver Board. Instructions on using the firmware can be found in the blog post: "Reuse LCD screens with the V56 Universal Controller".

This article is about fixing already 2 older universal TV Boards that can be used to turn spare left over LCD screens into good televisions or monitors. LCD screens in all resolutions from defect laptops or even new ones that this way cheap and easily can be upgraded to movie players playing MP4 or other codec movies from inserted USB sticks.

My older TV Boards have the no longer supported TSUMV29LU and TSUMV56RUU video processors and only were useful for DVB-T reception. Both have the 842 tuner chip on board. And when they are flashed with the wrong firmware they no longer work and normally require us to desolder the small sop8 Bios chip, reprogram it in a programmer, and solder it back on. Which is quite time consuming and needs to be repeated until the TV board finally works as was intended. Also because the matching bin file with correct LCD resolution needs to be selected and installed from an USB stick and booted from the USB port of the TV Board. Which most of the time is the wrong firmware version and makes the TV Board no longer accepting other bin files. And desoldering the sop8 Bios chip and reprogramming it needs to be repeated all over again until the board works with the selected bin firmware matching the LCD screen! And in the worst case scenario it will in the end also damage the solder tracks of the sop8 Bios.

What also doesn’t help is the poor Firmware support from those TV Board sellers, especially for older board buyers! There now is only one website that still mentions these older TV Boards and I had a hard time finding that one back, why I decided making this article! And the best part of that website is that it also gives the download links to the ORIGINAL Bios bin files we need to factory reset our firmware faulty flashed boards back to as new working TV Boards. That website also warns us for the wrong firmware versions that exist that make flashing these boards more complex.

Before I continue this article to show how easy it is to flash these Bios chips with a RT809H programmer without having to desolder these firmware containing chips ever again, here is that great older (and probably also newer) TV Boards supporting website (at best use Google by adding ‘V29’ or ‘V56’ to find that great Polish website): LCD4hobby.

Newer TV Boards are sold as Universal Scaler Kit 3663 Tv Controller Driver Boards and already support the new DVB-T2 TV format. As shown on above photo. If they really work in my and other countries I do not know. Because other receivers sold as DVB-T2 compatible receivers never worked! And I do not have this new 3663 board to confirm that it really works with our DVB-T2 transmissions.

My older DVB-T boards look like the one shown above. It can be jumpered into 3.3V or the 5V position. My TSUMV29LU board was originally jumpered to the 3.3V setting. And before you place it into the 5V position you have to make sure that your LCD screen also is 5V compatible! Because if it isn’t it will most certainly destroy a good 3.3V display! My TSUMV56RUU board was set to 5V but I do not know if that was how I got it. To be safe I put the jumper back into the 3.3V position. The original VGA board that only partly worked still showing the menu that no vga cable was attached confirmed that my LCD screen was still fine! Next photo shows how to connect the perfectly reading and writing RT809H programmer through the board’s vga connector port.

First our correct Bios V56 bin file was loaded! Next screen copy shows how the Bios chip automatically is recognized, erased and also the Memory protection is automatically lifted. (Here an older RT809H program version was still used. Later a new 20220919 upgrade version was found!).

Previous screen copies showed that different bin file versions were programmed, verified and accordingly easily tested with the LCD screen at hand. Here the 25Q32 TV Board bios sop8 chip was auto detected by my RT809H programmer.

As previous screen copies showed, programming over VGA from the TV Board to HDMi on the RT809H is a great and easy way to flash these sop8 bios chips without having to de-solder or re-solder them anymore again! So if you also have trouble getting your TV Board ready and working with your LCD panel, then go to the above mentioned website and if needed load there the original V29 25L8006E bin file in the download link to the DIY TSUMV29.rar file, or the download link to the V56_rom_dump.rar file that contains the original V56_rom_full_spi_flash_25_32.bin file. See for the V56 version this page https://sites.google.com/site/lcd4hobby/6-lcd-as-pc-vga-hdmi-av-tv-display-tsumv59

But the used VGA to HDMi cable connection not always works with all boards. When for instance a MT-6820-MD LCD board is tested with the VGA to HDMi cable it does not work! In this case we need the VGA to VGA cable connection with our RT809H that then perfectly works! See next screen copies that show successful reading and verifying the MT-6820-MD board with 25Q40 512kB Bios chip. Nice extra in our RT809H programmer is the built-in VGA monitor test pattern screens that show up when we attach a good working TV or monitor on the first VGA connector on the left next the 10 pin programmer connector of our RT809H programmer.

Still finding the large database Firmware packs containing all lCD screens and their firmware versions may be a big problem these days. I recently only was able to find the T.V56.031.rar file (123.855kB large!). But according to the author of the Polish lcd4hobby website that version is in compatible with my TV Board.

Also because it looks like many download links to these firmware files are infected with some kind of virus. Why most browsers refuse to normally connect to these often questionable websites.

Sadly all large V56 and V29 database links to all screen firmware pack versions on the LCD4HOBBY website are no longer working! So we must do with the still working original bios V29 and V56 TV Board files on that very informing website.

Luckily I had downloaded a few of those large databases with all different LCD screens in them already several years ago. One of them was called: LAMV29-16_7KEY_SCH_EXTERN_LOGO_842_POWER_LAST_KEYPAD_ANGENY_LG150925_ZLS.

So I hope you still are able to also find them if you still need these large files containing all screen resolutions with different screen manufacturers, and different 5 or 7 key boards used!

It is however still possible to for instance find many V29 firmware files after selecting the correct resolution monitor from a list on the Soft4Led website. But I haven’t tested any of these files.

What they also say that may help in solving faulty flashed TV boards, is the factory reset code when typed in by using the IR remote, or by using the local attached 5 or 7 keys. But I had no luck in using any of these codes.

There also is a Kazmi Elecom website. And we can try to post on the Kazmi Elecom Forum Page (https://forum.kazmielecom.com) General Discussion, faults/rectifications and Issues. But although I could access their forum , posting any question never worked and my account was never confirmed. So nice Forum, but no support! And also no luck on searching for firmware on the kenotrontv forum. Idem the https://forum.laboneinside.com/ much of the same.

But owning such a great RT809H programmer with free program upgrade support helps us to make security backups of all our Bios chips in our devices. The RT809H does have so many possibilities like next screen copy of the Toolchain menu, and many of those I still have to find out.

Which could be caused by in what country the TV was manufactured in if it depends on what firms made a pact to support it, or in what year it was made.

Anyway, this article shows that we no longer need to desolder the sop8/soic8 Bios chip to reprogram it. As was explained in so many articles. In those days the RT809H simply didn’t yet exist and we may count ourselves lucky that nowadays this great programmer makes it so much easier for us!

Getting those Bios bin files after your television or monitor is no longer booting up caused by corrupt or empty Bios chips, is often almost impossible. And most of the time downloading those from the internet is not free either! So you are warned. That of course goes for all devices that contain CPU’s with Bios chips.

Step 2: Downlosd the file and open, find your screen resolution and screen model number.copy it to your U disc.(If you can’t find your screen model numer in the folder, you can copy anyone to try, if not suitable ,try another one)

A controller board is a piece in an electrical circuit that interfaces with a peripheral object by connecting the computer to it. The connection may be with other computer parts, such as the memory controller, or with an external device, like a mouse, that acts as a peripheral controller for an operation of the original device.

The LCD controller board is often called the Analog/Digital (A/D) board. As a type of hardware processor, it allows for various video source inputs to be connected, selected, and displayed on the LCD screen. It does this by converting the different video input signals into a format manageable by the LCD panel.

In conjunction with the LCD controller, the LCD driver is a form of software that is the interface of and dependent on the controller piece. Combined, the two form an LCD controller driver board. As the controller connects the computer to the operating system (OS), the driver facilitates that communication. Though there is typically just one display controller per LCD, there can be added drivers to extend the reach of the drive to further segments of the LCD.

To generalize the process, the LCD controller/driver adjusts the input signal, scaling resolution if needed, and then outputs the signal for the LCD monitor to use. Some of these output interfaces are low-voltage differential signaling (LVDS), SPI, I2C, and Parallel.

In most LCD controller/driver boards, there are two other input/output systems. Both these systems, however, are two-way pathways. One involves controlling and monitoring options, such as controls for brightness, image, and color using the on-screen display (OSD) control panel. The other is for communication via connections like Ethernet, Bluetooth, or IP.

With modern developments, touch screen devices have become much more prominent, and so the touchscreen controller has as well. There are two types of touchscreens: the resistive one that measures pressure and the capacitive one that reads touch. In both of these, there are sensors that detect the touch signal which then transmit the signal data to the controller. The controller then processes the command for the OS.

To delve deeper into the details, consider the previously mentioned input signals. There are a variety of signals that LCD technology processes, such as VGA, HDMI, DVI, and DisplayPort. These computer display standards vary in format and characteristics like aspect ratio, display size, display resolution, color depth, and refresh rate. One of the biggest differences between these standards is their usage of analog signals or digital signals.

In an analog signal, the signal is continuous, but in digital, they are discrete values, typically of 0 and 1. Digital signals have become the most used, as they can more easily carry information and have better quality maintenance; if the analog signal is used and unnecessary information is present, it is impossible to remove it due to the continuous nature of the analog signal. In order to make that switch to digital signals, converters are used to replacethe real numbers of the analog sequence with a set of discrete values.

The VGA, short for video graphic array, standard is one of the most popular analog-based technologies. In recent years, however, the VGA interface has been overshadowed by interfaces like high definition multimedia interfaces, better known as HDMI, which has become a de facto standard for digital signal transmissions.

The HDMI is a combination of digital audio and digital video transmission. There are many HDMI connectors, such as the standard, dual-link, and micro. These connectors are what the input signal travels through to reach the LCD controller and to direct what to display.

The DVI (Digital Visual Interface) offers both analog signals, digital signals, or a combination of the two. Like the HDMI, it has various connector types for different signal types.

When crossing interfaces, we use adapters to bridge the differences between signals. The DVI VGA adapter is relatively inexpensive due to how compatible the two are. The HDMI is also very compatible with the DVI, making the HDMI DVI adapter quite simple.

The VGA to HDMI adapter, however, must overcome greater differences, as they are not naturally as compatible as each were with DVI. Not only are there differences in the analog/digital signals, but also the VGA only uses video interface, whereas the HDMI uses both audio and video. A cable and an adapter are needed to connect the two devices.

And last from the list of examples of input signals is the DisplayPort. It is similar to HDMI in its purpose to replace outdated VGA and DVI as well as its transmission of audio and video through its interface. The DisplayPort does not have as much variation in cables and connectors as the HDMI, with only one cable and two types of connectors. From the DisplayPort, there is a growing technology called the embedded DisplayPort interface, or eDP interface. LCD manufacturers have begun to gravitate towards this interface due to its fewer connections, smaller size, and ability to quickly transmit high quality displays.

Bringing the subject back to LCD controllers, with the various types of computer display standards, the video signal inputs can be a challenge to accommodate and translate for the LCD panel, but with the help of adapters and the growth of these standard types, displays continue to become faster and develop with greater resolutions.
