Question about Sharp Aquos LC-45GD4U 45 in. LCD HDTV
I was reading some of the others, and someone mentioned doing a reset by holding down a button while plugging it in.. how do you do that reset exactly? My TV won't do anything right now except blink that stupid power light.
The power light is an error code that tells me exactly what is wrong with the TV. Count how many times the POWER led flashes per second? (Dont worry about the OPC led)
1x per second (constant steady blink) = bad inverters/lamps
2x per second = bad power supply
3x per second = bad main board
If its 1x per second, try doing the factory initialization to get the TV back on to confirm a bad lamp/inverter.
Try doing the Factory Initialization (WARNING: THIS GIVES YOU ACCESS TO THE SERVICE MENU. DO NOT ADJUST ANYTHING IN THE SERVICE MENU OTHER THAN WHAT I PROVIDE YOU IN THESE INSTRUCTIONS. IF YOU DECIDED TO ADJUST ANYTHING OTHER THAN WHAT I PROVIDE YOU IN THESE INSTRUCTIONS, I WILL NOT BE RESPONSIBLE IF ANYTHING WRONG HAPPENS TO YOUR TV.)
If it is 2x per second or 3x per second, then those boards are just bad and they need to be replaced. There isnt anything you can do right now to fix it.
