TV can be on for 1hr up to 4-5hrs and it turns itself off.The main power cuts off and you have to turn the power off to reset the tv.After this the tv will work for 10min,1hr,3hrs.then it my do it one or two times more,after that the tv will work ok.This my happen every day or it may go 3 or 4 days,it may happen only one or two times a week. when this happens a red power down light will come no a power board in the rear on the tv.after reset the red light will go off.the red light only comes on when it shuts itself off.
Could be a few things.First check your sleep timer.Sounds like a fail safe mode that when the tvs left on accidentally it shuts itself down so it wont overheat and die prematurely.The last resort is to remove the circuit board and carefully inspect the solder joints near the power supply with a magnifying glass and a bright light.Then resolder those.
