I can turn on the tv and it's fine for about 20 min then the screen goes black with sound. I turn it off for a minute and it's fine for another 20 min. Like it's overheating.


It might also be a bad solder connection, short of checking voltages what I have done in this type of situation is with back off use a small fairly high speed fan - a hair dryer set to cool works, to cool areas of the boards inside to localize which board is causing this, with the set in failure, got it? it goes out cool it with a handheld hair dryer with air set to cool, when you find the spot where the problem is it will either instantly come back or try to.

Do it a few times to confirm which board is bad and locate a replacement board and swap it out.

TV screen goes blank but power stays on


Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.
