I understand, we need bit more troubleshooting and leave the question open to continue.

I need following info while problem reoccurs..

- Does TV switch back On itself or you press power button to get it On?

- Does sound continue or also stop?

- If TV stays On but screen goes dark, press menu or volume button on TV or its remote, does any graphics/ volume bar appear?

TV Technician: Shahid, Technician replied 2 years ago

Thanks for the info, there are two circuit boards in TV that can be cause of problem, either power supply board which has got failing capacitors and causing intermittent switch Off issue OR the main board is failing. I would swap power supply board as first thing to resolve the issue. Please click following links to view power supply and main board images, part number info..
