Power and OPC Lights flash twice and TV won't power on.

Hi, I have a Sharp Aquos LC-52D78UN 52" LCD TV and the Power and OPC lights are flashing green twice continually. When I try to turn the device on, the Power light stays solid for 1 second and then it resumes flashing with the OPC light twice without stopping. The Device won't turn on and I have already disconnected all external devices with no luck, any advice as to how to turn the TV back on?

      Press the power button on the TV and not the remote control. It is possible the remote control's batteries are dead. If the TV does turn on, you know you need to replace the remote's batteries.

      Disconnect the power cable from the TV, then insert it into a different electrical outlet. On occasion outlets are damaged, and do not provide a power current. If this is the case, changing the electrical outlet connection corrects the problem.

      Switch the television's input to a different connection. It may be possible you have the wrong input selected, causing the TV to give off a black screen.

    • 4
      Connect a different source device (such as a DVD player or cable receiver) to the television. If the source equipment is damaged, you will not receive an image from the hardware. If the TV still does not display an image, there is an electrical shortage in the interior of the TV. To see if there is any way to fix this issue, you need to take it into a local TV repair shop.

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)
