I have fixed many sharp lcd tv's with a reset. If one appears to have no defects like bad capacitors, fried inverters, broken panel, ect. and the power light is flashing steady or not on at all a reset may help. There is a lot of bad information regarding the procedure though. The correct procedure is to unplug the tv, hold volume down and channel up at the same time and plug it in. Release those buttons then push the power button. Did it start? Great! I have no idea why so many seem to need this. If there truly is a problem this will only work temporarily or even momentarily but many will be fixed for good.

    I am in the military and deployed overseas, so parts are limited. But we are a bit tech savy. We have a Electrical Engineer in the office and I am an electrican working on my degree in Electronics Engineering Tech. We have a Sharp LC-52D64U and it seems to have a power supply problem. We get the following code: Power>flash then Power&OCP>flash then repeats. I didn't find any bulging Caps. Will the problem be on the main Power Supply or the Inverter board in the middle of the back of the TV? Thanks!!

    Check the power to the inverters if their is a short in transisters it will feed through sense and not allow the power supply to come up. you will hear the relay latch and unlatch when it senses the short,I had a local Tv tech look at mine he was clueless on mine told me to throw mine out, no way after 2 years and $1500.00 decided to look at it myself cost me $20,00 got a board from ebay easy.

Sharp aquos tv opc and power led flashing

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 section 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 procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
