If this also happens on a DVD or video recorder, you could have a power supply issue or maybe a problem with the back light circuit. The best advice would be to take the TV back where you purchased it, if it is new. If it is not a new set, take the TV set to a repair shop for an estimate. Good Luck

Power button is green - no blinks / no picture / no sound


Unplug it from the wall, wait 2 minutes and plug it back in. if problem still exists, its probably the main pcb.
