Thanks for the info.- How long TV stays On and Off, any idea?- What video devices/ sources (such as cable box DVD player etc) are connected to TV and does the problem occur on all video input sources?
Expert:  Shahid replied 1 year ago.
I mean, when turn On the TV, how long it stays On - 10 minutes or an hour etc and when it switches Off, how long it stays Off and does it turn back On itself or need to press power button?Also, does power light on TV turn to flashing red any time during this off-on process?

are you there?

OK, if 'system update' option is On under Home menu > Product Support option which will keep the TV to get latest firmware then I'm afraid it seems main board is failing and causing the problem.- Have you tried to unplug TV power cord from wall outlet for 10 minutes to reset, replug back in and check? If not yet, can you try it now to see if it helps?If it doesn't fix the problem then main board of TV will be replaced to resolve the problem.I trust my input will help you out.
