SOURCE: 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)

Power supply is the place to look, look for bulging on top of the capacitors in the secondary side of the main power supply.
