Question about Televison & Video

3 Answers

I have a sharp LCD TV model LC-52D64U that does not power up. When I plug it to the wall outlet, both the power indicator light and the opr light on the front of the unit flash three times and shuts down. What is the cause of the problem and how can I fix it ? Thank you.

    Thank you for your reply.
    Would it be easier to replace the whole power supply unit since I could do it myself?

    Dear Pagebor, I have replaced the power supply unit and the same problem is still there. I also observed that when I plug the TV to the AC outlet, a relay on the power supply board clikcs and a small red LED near IC 2008 on the main board flashes. I hope this helps you in any way to find the problem.

    Thanks again !

    I have replaced the power supply unit and the problem is still there. Also when I power up the TV, two small red LEDs on the main board flashes, one near the main CPU, and one near IC 2008. Hope this helps you in any way.
    Thanks again.

Why wont my sharp lcd LC-32D44U turn on?


Well, there could a be few issues. First thing is to verify the breaker that gives power to that wall has not tripped off in the home's break power panel. If it is not tripped then verify the wall outlet that the TV is plugged into has a reset button, like a GFI (ground fault interrupt) If it does then verify that it has not tripped. If the GFI on the wall plug is tripped simply push the reset button back in and then try plugging in your TV power plug again. Then if that checks out or does not have a GFI outlet, verify that the power plug going into the back of the TV is not loose. Unplug and replug power plug that plugs into the back of the TV in and verify it is securely connected. Lastly, the power supply in the TV might have gone out.

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 !
