Hi, I have a 42 inch LCD from LG, part number LC420WUD-SBM4. This is from a broken TV (German brand Loewe, model Art 42 SL). I would like to misuse this LCD as a picture frame. That panel is a bit special, since it has 4 x LVDS channels with 10 bits each, but only WUXGA (1920 x 1080) resolution. I have been trying to find a controller board with HDMI interface for this panel, but was not successful. Any tips, where I could find one ?

This panel fits Main Board EAX60890803(3) for LG 42SL8000 -
Thanks for the answer, but this is another complete TV. I was hoping for a HDMI LCD Controller Board similar to that one: https://www.amazon.de/Controller-Boa...06WVMPWHP?th=1
Again, I would like to misuse the panel as a picture frame.

Have you looked on AliExpress ?Comment

I did look on AliExpress. If I search for the panel name, only TCON boards show up. If I refine my search for e.g. 4 ch LVDS 10 bit, some boards come up, but no info, on whether timing could be adjusted, ... My experience with AliExpress is, that you usually get a board with no additional collateral, so no info how to adjust it. I also sent mails to some of those vendors, however no response from any of them. As I am not so experienced with LCD control I thought someone here might have additional tips.Comment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Problem
This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached.... -
I recently bought a used tankless hot water heater and the controller board is completely dead no power up when power is applied the display board works however the main controller board does not work correctly at all the fuse is good
I bought a used replacement controller board that also had issues that I was able to fix and now the tankless water heater works correctly now
However I would like to know if I could figure what happened to this controller board if possible
Tomorrow I will take some better pictures of both side of both boards

Hello gus,
Just have two XS002 controller board for Epilog laser engraver for repair, looking for any schematic or doc on those board. So far I could only find the "Service training manual", but it's for the whole unit, not specific to the controller board and there is very little info on the board itself.
For instance I don't even have the connectors pinout

Hey all, want to poke the hive mind here for a technology I must be missing something critical about I can't discern from looking at spec sheets alone.
I have an ATGames Legends Pinball machine, the playfield is a 32" LCD Display. I'm trying to attach an LCD controller to it for direct PC access, as others have been successful.
The LCD is a SPLENDID CD320B01A-350 (I think it's a custom panel for ATGames as google turns up nothing), which is mated to a HV320FHB-N02 (47-6021088) T-CON board (this is probably the important component anyhow)
The LCD...08-31-2021, 09:42 AM
