Hello John, Welcome. My name is ***** ***** I'll assist you today. I'm sorry you're having trouble with it. I need additional info to troubleshoot the issue.
- How long the TV stay On and switches Off?
- Does it happen once when turn On the TV first time?- Does the problem occur regardless of what video source being watched on TV?
Thanks for the info.
How old is the TV and how long it have had the problem?This info will conclude the troubleshooting.
Thanks John for the info.
It seems TV main board is failing for some reason, it could be heat/ temp issue that increased inside main controller chip that resets it or a firmware issue as there is no other reason for this kind of intermittent problem and you would need to replace main board of TV to resolve the problem. If you wish to do-it-yourself then need to remove back cover of TV after removing fixing screws around the back panel to access inside TV then get the part number off of label pasted on main board to search/ google it to get price info to order it. Main board replacement wouldn't be hard work for an average handy person. I trust my input will help you out.

Yes, it could be reason of increasing temp that turns Off the TV after some time. Take it off of wall and put it on table stand to see if it works fine/ longer.
