So a week or two ago, my TV’s LED was clicking on and off but the display wasn’t turning on, so I looked it up and tried to diagnose the problem on my own. I discovered that the TV would stop clicking when the Z-board was disconnected, so I ordered a new one with the buffer and replaced them. And the TV ended up working! However, this weekend, after being on for 10+ hours, it randomly shut off and turned back on, which is what happened before the TV started clicking. The TV is still working, but I would like to try to fix whatever is wrong with it.
@crayolas it’s the Y-sus board that supplies a 15V to the Z-sus board without which your board will turn off. A lot of times it’s not the Z sus board burt the Y sus that causes this. So, check that and first and foremost this could be a power board issue. Also, its a Plasma and they get hot. Make sure you have good airflow and get a fan to try and move some air. Let’s see if that makes it do different things :-) When you have to time to work on it etc. Go ahead and post some good pictures of your boards and interconnect cables with your Question. that way we can see what you see.
