So I purchased a basement level RCA 4k tv....Always a great choice....Anyway, what's happening is the screen is going black on me. still have audio and the remote functions and the indicator light stays on(as if the unit is still on).

I've begun to read a little bit about the internal components and I think I understand that there are a couple of pcb's in there and one of them is probably the culprit.

Here's my only hickup: In the first 15 minutes of using the tv, the tv will go black. I turn it off and then back on again and it works....then it happens again...I repeat this process 4 or 5 times and then all of the sudden the tv will be good for the rest of the night. Like it literally doesnt turn off again.

So If it ALWAYS stayed black, that would be one problem but I have a situation where it "warms up" and then stays working.

I'm somewhat handy with a multi meter and feel that I am capable of testing and ordering the correct replacement board.

Can any one share some thoughts on this?

Thank you
