I had left it off for a couple days and then tried again and it keeps repeating the issue
Expert:  Shahid replied 1 month ago.

OK, just to clarify, when TV powers Off, it turns back On itself without pushing power button, is this correct?

OK, it is main board internal failure that is causing rebooting, please replace main board to fix the problem. Main board is one where video/ HDMI inputs are located. Please click following supplier link to view main board image part number info that can be used to search/ google to get replacement board price info if you have plan to do it yourself..

I'm sorry there is no easy or quick fix for this problem and it is definitely hardware failure that needs defective board replacement to resolve the issue. I trust my input will help you out to make decision about this TV repair or invest that money on new replacement TV.
