The screen keeps going black for some reason. Whether its on for 5 minutes or an hour. I've tried unplugging it for 15 seconds and recycling like advised but it's still happening. The tv stays on because the light stays on just the tv goes black. Anyone had this happen or know of a solution? I haven't sent in the warranty yet but will soon. Just wondering if there was a simple fixing i'm just not getting. Also the sleeptimer is not on. Is there a way to reset to default settings?
