It is completely random, sometimes will just flick on and off now and again, sometimes it’ll stay one way or the other for a few days. See: https://youtu.be/imiNzNXKkFc

It is on all inputs and the OSD, I’ve tried leaving it unplugged for a few hours and fiddling with backlight related settings.

After a while of intermittently occurring, it seemed to have stuck for good. So I completely disassembled it to investigated the boards, connections and LED strips. Everything looked fine, and of course it decided to just start working perfectly again… for a while. After a few weeks of working perfectly it’s started happening again!

Any inkling on what could be the cause?

I let it dry and plugged it in and it worked fine. The next morning the tv wouldn't even turn on but the red light is lit & disappears for a second when I first try to turn it on but it quickly comes back. The tv is also making a weird weak sound when I press the power button. Well, my actual question is if it is an issue with the power board, can I replace it with the power board from a Samsung 55” smart tv?
