    Tv came to me with a not turning on issue. but when I plugged it in to see what the issue was the tv worked as I was watching it for about 3 hours it turned off the backlight and continued playing sound, I restarted it but backlight would stay on for a few seconds after this attempt.
    So then I pulled it apart and this is what I found.

      Thank you for the follow up, not many people will do this so we never know if a repair worked.

        I know I hate when you come to the end of a thread and theres a dead end, did it work or did it not work.

        I am currently working on the same board again I made another thread as its a different tv.
