I have a sharp aquos lc-c4677un its not turning on at all now. When I push the power botton on the tv, the power light turns on and about 2-3sec the power and opc light start to blink and thats about it.


How are the power and opc lights blinking? Do they blink simultaneously or does one blink then the other? How many time do they blink per second? Also have you had it fixed yet? and if so what was done? I had a similar problem with my set.

Sharp TV LC37D40U Aquos malfunction. It fails to turn on (no picture, no sound) except that power button light blinks off and on continuously. Any ideas. Thanks.


The blinking light is a indicator of a internal failure, it usually blinks as an error code, I have two suggestions, unplug the TV from the power outlet and let it set for at least 30 minutes not plugged into the wall outlet, then plug it back in and see if it has returned to factory defaults and returned to normal operation, if that didn't work then contact sharp @ 1-800-237-4277 and they will gladly assist you. Good luck !

Sharp 52" Aquos LCD Will Not Turn ON-Blinking LEDs


I had a similar problem. Fleeting video, then audio only for few seconds and then nothing except the green power LED blinking on and off.
I changed the power inverter board, backlight inverter boards and power supply board but still the problem is not gone.

Just 18 month old TV and out of warranty.

Have a 30" SHARP Aquos LC30HV2U that has a bad power supply. Nothing happens when I turn on the LCD - though it is getting power confirmed by green light going on but nothing on LCD. Visual inspection


You did try the CLEAR button on front of the box?
One possible idea is the cables going the box to the TV. ( might be bad )

If your sure about the problem, you can get your Service Manual here:

This with have all the schematic, diagrams, part number, and test points you need.

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!!
