These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power led, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating, to many popular brand TVs and other devices.

SOURCE: No power on LC32D50U Sharp

bobnyc, Is set under warranty? How old is it? Did it display a "perfect" picture yesterday, and not today. How is or was the AUDIO. Can you hear anything or nothing? Is the SMPS power supply board a "COMBO" or is the INVERTER supply located elsewhere? To where do the CCF tubes connect to get power? Tell me, do u have a good DMM, 100mhz Ocilloscope, Isolation transformer, and soldering iron/ solder wick???? If have some answer to some these ??? contact me @ louie12fix on fixya or at lmistyrel @aol.com PS: I highly recomend use of digital cam to take pic's before taking stuff apart. Could help when reassembling.

SOURCE: power light flashes twice,then opc flashes once then power again

In all the time that you have had the tv have you applied 2 firmware updates that some of the tv's need to avoid other known issues with the lcd in the future. These firmware updates are for the main cpu PH1UU112 and the monitor MD1UA104. I don't know if this is the case for you but it worked for me. Call Sharp at 1-800-237-4277.

SOURCE: TV won't turn on

the first thing that you need to do is to open the back cover of your tv.Go to the power supply section it is separate board where the power cord is connected.Using a multitester,plug in the power cord and measure for the output supply.see if the 5vdc ,12vdc and 24vdc are present..if one of this output is missing,replace the power supply board But if the output voltage are complete,replace the inverter board,It is a board that supplies the high voltage to the backlights of your monitor/screen....You can also try to reset the system of your tv by pressing the the small switch mounted on the main board press it twice while the power is on...tnx and good luck!

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.

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!!
