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.
