Hello Marc, I have similar problem with my LC-42D43U. The background was kind of white therefore I purchased a harvested main board and installed. The symptom still occur then I looked around inside the TV and read few articles indicating that it my be the LCD controller or CCFL backlight lamp causes the problem. I turned on a day later and the symptom of the power light and OPC starts to blink and picture doesn't appear at all (power blinks 1 and OPC 4 times) . I followed your instructions of "running Industry INIT. But, not effective. I don't know what to do because I calculated that I have turned on my TV about ~4000 hours.
Please advise. Thanks.

Marc the model number you provided does not come up in my system. Can you check the back of the TV and see what it is listed there? Also, can you ask a new question to try and keep the same models in a question?

Correction. The Power and OPC blinks twice together, then the OPC blinks three time after that. The pattern repeats.

I tried to INIT process as shown above but the K doesn't appear as in the picture. Again, my sharp model is LC-C46554. Please HELP.

Hello. My SHARP TV model is Liquid Crystal TV LC-C46554. The Power and OPC are flashing with the same pattern as Anonymous above: Power flashes 2 times then OPC flashes 3 times.

Any input is greatly appreciated.

The error that you have is a voltage error. The voltage is used on the main board and the power supply. A technician would need to take some internal measurements to determine if the power supply is supplying the proper voltage or something is disabling the voltage on the main board. I have seen the problem be on both. More common would be the power supply.

The power supply is about $125 and the main board about $275.

Please provide the blink pattern. If the power light is blinking 1, 2, or 3 times then the problem could be the power supply or the main processing board inside the TV.

I know how disappointing it is when your TV isn't working. An expert will be able to provide you with a detailed response. It usually takes 24-48 hours to receive a response. If you'd like to schedule service I have attached the Sears Home Services website below. Have a good day.
