OK if you have blinking red light.

Try to open the cover then disconnect the inverter board after that try to power it on again..

If the light stays in blue (LIT) and of course you don't have picture or backlight you have faulty inverter board that need to be replace.

The pattern of the blinking is a code. If the power light is blinking by itself once per second or thereabouts it could be loose connection to Inverters, reload firmware, Inverter Unit or LCD Panel.

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

There isnt really anything you can do to fix it yourself, youd have to call Sharp to locate a local service center.

1 Answer

No POWER


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

1x (steady constant blink) = Lamps or inverters
2x = Power Supply
3x = Main Unit

If i am reading it correctly, looks like the POWER led is flashing 2x, which means it is a power supply failure. Either way, your TV needs to have a board replaced, there isn't anything you can do to fix it yourself. Try locating your local sharp authorized service center to repair your TV (1-800-237-4277)
