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)

Unplug the unit for 1 minute, replug and try again. If it doesn't work the power supply is faulted and it needs professional service.

Same problem. TV worked night before and then would turn on but no picture or sound. Power and OPC lights blinking. I couldn't change the channel or get to the menu.
I disconnected the coaxial cable and the power for a few minutes and then plugged it back in (electric) but left the cable off. I got a message that it couldn;t get a signal. At that point I was able to change the channels. I plugged the cable line back in and everything worked fine... Good luck!!!

It's a power supply related problem. When it turns itself off, this it called protection mode. The TV automatically turns off to protect other parts form being damaged.
The most common problem is the Power Supply Unit or the Backlight Inverter Board.
You may have to take the TV to a repair shop to find out which one is bad. Paying a repair shop to replace the board for you maybe more than the TV is worth. If you let them diagnose it and you replace the bad circuit board yourself, it would be cheaper.
Here's a place I use to get parts for TVs:
The problem is the repair shop may charge you double or three times of what the part costs at the web site link above. Then, plus labor. I just want to save you money. :)
