i have an element 37 inch lcd which powers on and just shows a black screen (meaning the backlights work, but no actual picture) i've researched but cant find much. what happened was, i was using the tv as a pc monitor, when all of a sudden, the power went out and i guess it was a surge. well when the power came back, there was no picture anymore. i tried changing inputs, but nothing worked. i took the tv apart, but didnt see any bad caps or damage to the boards. is there something i could be missing?
