Hello Tom, my name is ***** ***** I'll assist you. I'm sorry you're having trouble with it.

I need additional info to troubleshoot the issue.

- Is the TV still under warranty?

Thanks for the info, it seems main board internal failure where main controller chip switch Off TV power when detects an error in boot up process and main board will need to be replaced. I am really sorry about this and you are going to have to return the TV to have it replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you.
