“TV keeps shutting off After set up and all channels were programmed the TV will not stay on. It keeps shutting off after only a few minutes of playing. I checked trouble guide and it says to check sleep timer which it is shut off but still continues to shut off after only a few minutes of being on. It doesn't shut down completely because it still has power but no picture or sound and pushing on channel button doesn't bring it back on but pushing recall does but again after a few minutes it goes back out again. Also the power light comes on after TV is shut off and goes out when TV is turned on. Shouldn't that be the other way around?”
