    I have a different idea:
    - I am going to sell the T-Con AS-IS, and I will ask the buyer to let me know if it works.
    -- If no, I will buy a replacement T-Con.
    -- If yes, I will sell the main board AS-IS and I will ask the buyer to let me know if it works.
    --- If no, I will buy a replacement main board (and t-con, since I will have already sold mine).
    --- If yes, I will sell the power supply and throw away the panel.
    this try will never burn or damage any parts of all 3 boards .. the only one will effected the panel.

      Ok, I got brave and tried it. Did not burn up the panel. Basically, nothing different happened. Same as initial state.

      - Plug in power
      - TV relay click
      - No picture. Not even a flicker of light.
      - A few seconds later, got the TV input static sound.
      - No picture. Not even a flicker of light.

      Tested all the voltages.
      P201: 24VS=24.8v, 12VM=12v, DPC=0v, P_ON=3.5v, DRV_ON=3.5v, 12VT_ON=3.5v
      P202: 12VT=12v
      P203: 24VD=24.8v

        from all the photos you showed here there are no sign on burned cells.. also this panel need to give it another chance..
        some of the old version of this OLED panel module we can access to the panel driver boards and some cannot. but if you try got access to this. its not different from any other LCD panel could have ceramic caps shorted.

          Quick update. I got a 2nd t-con board and ran some of the same tests as before (standalone mode, IN_STOP 0413, SWI3000). Still no picture.

          I'm thinking this panel is bad.

            Any luck? I'm having similar issue and already replaced all the three boards.

              UPDATE: I finally got a replacement main board. Fixed. The original main board was the culprit.

              Thanks for all your help, Diah!
