Facing TV Problems? Ask a TV Technician.
Hello, I'm Shahid and will assist you.
If TV turns back On itself then switch Off and on again then it would be main board internal failure where main processor chip resets due to internal issue and reboots and this keeps going on.
Swapping the main board in TV will help to resolve the problem, please check following link to view main board image and price info if you wish to replace it in TV by yourself..
I trust my input will help you out. Please feel free to respond if you have any additional questions.A positive rating to answer would be greatly appreciated, please click on smiley face/star on this page then click submit/finish button so I can get credit on website for my work. Regards,
