Question about Sharp Televison & Video

1 Answer

Sharp LCD Aquos will not turn on.

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. :)

SOURCE: Sharp 52" Aquos LCD Will Not Turn ON-Blinking LEDs

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.

SOURCE: 52 sharp aquos tv wont turn on. Hear click of tv

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.

Switching of opc and power light when tv is turned on but no picture


Use a flashlight 2 inches away from screen to see if you see a picture, if so then it's your inverter boards that needs repair or replacing. If no picture then power supply board may have bad caps

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)
