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.)
and hold at the same time “Vol –“ and “input” button on the TV set.
holding those buttons, plug the tv back in
- the tv
should turn on by itself, keep holding the buttons until the letter “K”
appears. Then let go.
Once the TV turns on, take a look at the screen. Does it flicker then shut off? Or do you hear a buzzing noise from the right edge of the TV? If so, then you have bad inverters or lamps. Once youre done, unplug the tv to get it out of the service menu.
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.
