SOURCE: Power light flashing/ no picture

I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.

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!!!

SOURCE: LG 47LC7DF Green Light Blinks 16 Times - No Picture or Sound

The lights indicate what the issue is. Kind of like your check engine light in your car tells you something is wrong with the engine.

This going to be tough one to figure out, but at least the back light inverter board and power supply are working, unhook it at least 1/2 hour?
You may have bad main logic board problem. Try reading my guide here and see how much the main baord may cost you.

OPC and Power green lights blink twice, tv will not turn on.


follow this instruction and fix it. God bless you

      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.

    • 2
      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.
