You can try to unplug the TV for that long and see it it works.
There aren't service parts available for these LCDs.
If unplugging the TV does not work, the power supply will need to be repair.
I service these power supplies.
If you need further assistance. You can send me an email to

I have a panasonic 50 inch plasma it blinks 7 red lights.

Try changing the input device to something you are sure works. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

Blown Fuse LG LCD

Unplug tv and let it set for a couple of hours. Remove the back panel, the fuse is located somewhere near where the power chord comes in. Remove fuse and replace with one of the same rating.

The TV no longer works. The red power light on the TV no longer shines as it did when the TV was off. Any idea what the problem might be and if it is worth repairing? The TV is only 5 months old.

D10 is shorted. HER304 in middle of Power supply board near large electrolytic cap. Replace with Radio Shack 276-1144 3A 400PIV Diode. PLEASE BE CAREFUL WITH HIGH VOLTAGE PRESENT ON POWER SUPPLY BOARD. UNPLUG POWER CORD!!! OBSERVE PROPER POLARITY WHEN REPLACING DIODE-LOOK WHERE THE BAND IS.

PS- I just fixed this same problem this morning on same model.

Tv shutting off

How many times per second does the POWER led blink? (dont worry about the OPC).

1x per second (constant, steady blink) = bad inverter/lamps
2x per second = bad power supply
3x per second = bad main board

You can buy the parts online and fix if yourself!!
