If the TV does not stay on, press the POWER button on the control panel for at least eight seconds to perform System Reset. The TV will turn off. Power on the TV and the green LED will flash quickly for about one minute. The changes you made most recently, before using SYSTEM RESET, may be lost. If this happens frequently, obtain an AC line power conditioner/surge protector.
An unusual digital signal may have been received, triggering a protection circuit. Wait for the light to stop flashing and turn TV on.
Momentary power fluctuation caused the TV to turn off to prevent damage. Wait for the green light to stop flashing and turn the TV on again

Problem solved. I tried playing DVD and the TV picture was fine. So I double-checked cable wires from cable box - one of the wires was loose (obviously it was the red color input). After tightening, the TV picture is good as new.
