I have an old Samsung UE55C8000XPXZT that after a storm started to shutdown itself after a few minutes of use. While I’m using it for the few minutes it stays on, it behave normally, after that the display flashes a couple times and it turns off (but the TV is still on even tho black screen and no audio). To revive it I have to unplug the power and leave it rest for a while.
Here is a video of the board: https://streamable.com/lvaxhh
Maybe someone can help me identify the issue. I’m quite affectionate to this TV and I’m all in for saving money and the environment without going for a new one.
I can’t tell from the video but I think you might have a dead capacitor somewhere. I’d suspect on the psu-board. Look for one(s) that bulge at the top. Just look online on how to replace them if this is the case. Fairly easy and cheap.
This is one of the things i tried to look for immediately but i did not find anything wrong
