    OLED T-CON driver boards are not as LCD t-CON. it work with 2 rails.. 1- 24 V EVDD to handle OLED cells and second one 12V VCC to the t_CON signal process

    at yours set 24V rail come from PSU direct but the 12VCC t-CON come from MB.VIA LVDS this why we disconnect the MB LVDS to T-CON and take the 12 V direct from PSU to T-CON fuse at time we want TESTING psu + T-con + module AS STAND ALONE:

      Yes that’s what I did in my latest tests. I got it wrong initially and figured it out afterwards.

          But wouldn't a new one show artefacts because of the mismatched panel calibration?
          I've expressed many times my theories here in other threads, i don't want repeat myself, the only requisites i have expressed in previous post, it's up to you, i'm not here to let users lost money, the counterwise..

            Nothing against you, I'm grateful for everyone's help here. I was just confused by your post #19 because at that point in the thread I was already doing the test correctly as you describe.

            Davi.p, I simply wanted to set my expectations right. I'll do some more research and tests today.

              LG 55NANO77SRA TV – Menu scrolling by itself even after removing button board (Main Board EBU66792103)
              by ygorsan
              Hi everyone,




              I’m looking for help with a persistent issue on an LG TV model 55NANO77SRA, which uses the main board EBU66792103 (also used in LG UQ80 and NANO75/NANO80 series).







              🧩 Problem Summary:
              • The TV keeps scrolling through the menu or selecting items by itself.
              • I removed the physical button board (the entire panel with power and volume buttons) and also disconnected the flat cable (CN202) from the main board.
              • The remote control is not in use (batteries removed), and the TV still shows the same behavior.
              • I
              ...

              Issue: No Power, Then Rebooting After Main Board Change

              Short answer: replace main board and power board
              Technical answer: replace main board and Q306 & Q307 on power board.

              Long answer:

              TV wouldn't turn on. Power switch was fine which means the main board isn't processing the power on signal. Replaced main board. TV turns on now but randomly reboots. Bad main board? EEPROM? Tried to pull main board and got a shock touching the corner of the board. That's weird. C334 (450V 10uf) capacitor is still holding a high charge....

              Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
              Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

              Is it possible to upgrade from a Vestel 17MB97 main board to a 17MB110 Main board?
              by cheeky2
              I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
              Obviously the same LVDS connector for the screen connection...

              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....
