SOURCE: No picture, but power is on...
How many times does the POWER led blink per sec? (dont worry about the OPC)
2x = power supply (not as expensive to fix)
3x = Main board (expensive to fix)
SOURCE: Blinking power and OPC lights
If you have tried to reset the TV by unplugging it for 2 minutes and still have the same issue then it is time to bring the set to a repair shop.
SOURCE: My sharp LC-37d62u display problem
This problem very common in sharp tv.The POWER,OPC flashes.First turn on have power LED indicator light stable at all? Tries the power again couple times will have backlight come back on,than it will work.Not at all more than 5-6 times than ur main turner signal board is the problem,must replaced.
Testimonial: "Took a part back panels looking at the circuit board power capacitors, plugged in TV to power outlet, and powered up normally."
SOURCE: Sharp LC-37SB24U will not turn on
From the information you have provided failed capacitors in the power supply is likely causing the problem. The safety circuitry shuts the TV set down when it detects a problem. This model of TV has over 2,000 parts which include millions of transistors inside the integrated circuits. The capacitors will change value, leak and become defective. Resistors will change value and burn. Integrated circuits and transistors can go bad. This can cause other components to become defective, which can have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again since if the parts that caused the failure to begin with are not replaced. The only way to know for sure what is causing the problem, which parts that are no longer within factory specs and for proper repair all the electronics must be diagnosed by someone with the correct electronic test equipment and the skills to use the test equipment. The repair should cost about $250 if carried into a TV repair shop. A small TV repair shop will often charge less than a large repair facility.
SOURCE: My Sharp LC-42-D62U won't power up. The power
Ur Tuner signal board have problems or dead.Ur power LED light indicator stable for a few mins before the power LED light,and the OPC LED light indicators flashes?After the POWER light and OPC light indicators flashes,just push the power button again for the power recycles again.Probally have to pushes the power button 3 or 4 for power light and opc light indicators flashes,the LCD backlght will lght up and work.Sharp tv have this problems alot,very common in Sharp LCD tvs.
