Please check the pattern of blinking (for example: 7 blinks, pause, 7 blinks, etc.), and let me know what blink pattern yours is doing.

10 blinks pause 10 blinks

Thanks for the reply. There's not a reset button on these sets at all, and a 10 blink code indicates a failure of the Mainboard or the power supply board.

However it's worth it to try a hard reset, as sometimes the processor in the TV can simply have locked up.

The first thing you would try, is disconnect the set from power, then press and hold the power button on the TV itself (not the remote), for 10 seconds and release. Then plug the set back in, and also check that the power cord is connected tight at the TV as well. Press power once, and see if the set powers up normally. Try this procedure up to 2 times, and please let me know what happens.

If the issue goes beyond that - then this does indicate a hardware fault in the set, with the power board or Mainboard that requires repairs. There are no settings/adjustments that will cause the TV to shut itself down. The only other attempt at a quick fix, is to leave the set unplugged for several hours in the hopes that it resets. The average cost for this repair is in the $200-$250 range (depending on which board has failed) and if you'd like you can use the link below to locate a shop in your area:

Other than that, I'm sorry for the bad news and wish there were a quick fix.
