The clicking sound may be a power relay coming on and then off--problem indicates a trouble in the main power supply.

count the number of times the led blinks and let me know. Do you hear any clicking from the back of the unit???

This problem very common in sharp tv.The POWER,OPC flashes.First turn on have power LED indicator light stable at all? Tries the power again couple times will have backlight come back on,than it will work.Not at all more than 5-6 times than ur main turner signal board is the problem,must replaced.

I had the same problem with the Sharp Acquos LC-32GD8E. A repair man was able to fix this by opening up the back cover and tightening the metal (ground) shield. the screws seem to have come lose. If I had known this I would have done it myself!

You might try pulling the AC plug out and leaving it overnight. Since many sets are now using a little flash memory that does not require constant power to remember stored settings, this may not work.  

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)
