The cause of OPC and Power light flashing frequently is the board of the power supply.
If you have a little bit a knowledge how to work with soldering iron you can fix it.
Generally the main cause are invisible cracks or dry joints and cold soldering.
Turn TV OFF and disconnect from outlet. Remove TV back cover. Remove board with transformers (power supply).
That board has many components on the back side. Try to see small cracks or not properly
soldering dots. Use some magnifier. Resolder all not good soldering dots. Done.
Assemble back your TV. 80% is successful result.

Sharp power opc light blinking three times


The code that is flashing usually points to a main board failure. I would recommend getting it diagnosed. If you want to be gutsy and try and replace the main board yourself, MAKE SURE YOU GET A BOARD THAT MATCHES YOUR PART # EXACTLY. Sharp makes several revisions of main boards for various models, and they ARE NOT compatible.
