Question about Sharp Televison & Video
My Sharp 52' inch LCD Aquos television will not turn on. When I try to turn it on the "power" light and the "opc" light flash together and have a clicking noise as if it is going to turn on. When it does not turn on, the lights keep flashing together and then the "power" light will flash by itself. I have took the back off to see if I could hear where the noise is coming from so I can get the part to fix it. I have went to Fry's, Conn's and Best Buy, and none of the electronic stores carry the model that I own. I loved the television when it showed, and I would rather attempt to fix it as opposed to purchasing a new television. Could someone please tell me if you are aware of a possible solution? Thank you in advanced for your response. :)

I had a similar problem. Fleeting video, then audio only for few seconds and then nothing except the green power LED blinking on and off.
I changed the power inverter board, backlight inverter boards and power supply board but still the problem is not gone.
Just 18 month old TV and out of warranty.

This is very common in sharp tvs.U turn it on.U get power on light stable right?U hear a click,one or twice,sometime tv is good right?Sometime POWER light and OPC light flashes?Push the power button on/off couples times will work, picture will come on.If keep trying off/on couples time after POWER and OPC flashes,don't ever stop and never get backlight and picture.Ur Video backlight board is dead must replaced.

This tends to be the result of an electrolytic capacitor somewhere, either on the main board or the power supply board bursting due to overheating. In this case you can pull off the back paneling and review the boards over to make sure all the capacitors are in excellent condition. After identifying a bad capacitor you can buy one from an electronics store in the area or a reputable online source. To replace it this will require soldering. Look for a capacitor with the same uF, the voltage can be the same or higher. Make sure all the power is out of the system before servicing, also make sure to note capacitor polarity observing the negative indicator line on the side. If your not sure this can be done at home I would recommend taking it in to a servicing shop. If you do not know what a capacitor looks like do a google image seatch for both examples of a good and bad copacitor. I honestly hope it's something much simpler, I hope this helped and good luck.
