Re:When You plug in power cord to outletPower light and opc Green Lights Flash On TogetherThen Power light Blinks by itself.

I have done several Aquos in real life, and I should be able to help.

That is protect mode (forced standby), that indicates that an internal fault has ocurred.

Sharp Aquos may not give any error (blinking) code when this happens. In that case the TV must be taken apart and tested by a technician.

If there is a code error, that is given by the way the power light flashes, in that case let me know if there is a standard pattern, and let me know how many times the power light flashes. The current description does not fit any code.

Thanks.

    I understood that OPC light flashes once. I need to know how many times power light flashes.

    If for example the power LED flashes twice and OPC LED flashes once, that means that there is wrong voltage in the 10V circuit. In that case the technician will focus on that problem.

    I must warn you that even knowing the error code, the TV must be tested and repaired by a technician. An LCD TV cannot be repaired without multimeter and iron in hands. At least without testing there is a big risk of buying the wrong expensive part.

    Hi.

    That means that the power LED flashes once, and that OPC flashes twice. Sharp Aquos codes repeat cyclically.

    Problem detected is a power error. In most of the cases this mean a faulty PSU. The PSU must be tested and fixed rather than being replaced, as the main controller board may also be responsible.

    If the OPC led flashes twice cyclically, then the problem is on the 3.3V line in the PSU. Testing is carried jumping the control line for 3.3V and checking if there is voltage in there.Testing must be done by a technician. Repairing an Aquos PSU ranges between $150 and around $250, depending on part price. Cost may go up if instead of PSU the problem is digital board.

    Here relevant part of service table:

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


follow this instruction and fix it. God bless you

    • 1
      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.

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.

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)
