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.

Testimonial: "Thank you so much. I was thinking that it might be something easy to fix but wanted someones info before I ripped it apart and screwed it up. I'm going to give this a try and I'll let you know how it turned out. Thanks again"

Tv screen goes black after 15-20 seconds

It's not the TV from what I can tell. I would start complaining about it and say you want a brand new box. Not used. They tend to give out boxes from people who previously had them and either didn't pay their bill or moved and clean them up.

TV has gone into "protect mode" to do just that to protect against the damaging failure that has been detected, you will need a servicer to diagnose the failure. Good luck and Merry Christmas!
