    The guy only tested the capacitors on the board. He said all the capacitors are good. If the capacitors are good can the board still be bad? It wont power up, just a green blinking light.

Blinking light is an error code. Count the blinks before they repeat. Check your manual in the troubleshooting section. If you can't find it, contact a Sharp service center or try and get a service manual. Reset info is also in the user manual but you can't do it if your set doesn't power up. Are you sure about the power board?

    Yes, the board can still be bad. Voltages should be checked and they should be the correct voltages and clean (no HF ripple). If one is off, it may not power up. I had a bad power bd a week ago, also Sharp, voltage was 40v, should have been 60v, set would not power up, flashed an error code. This set was different model from yours.

The pattern of the blinking is a code. If the power light is blinking by itself once per second or thereabouts it could be loose connection to Inverters, reload firmware, Inverter Unit or LCD Panel.

My Sharp Aquos LCD TV LC-40C37U will not power up. The green power lamp at the bottom right is blinking. We had a power surge last night, I even measured 180V on the power outlet. Is my TV now damaged?


Good day sir/maam, chances are, yes or no, yes, the surge do has the ability to damage your TV, but no, modern TVs are autovolt (it can work from 90v-240v) so check the manual or back panel to confirm. The most deadly part of the surge is it can hit more than 500v at a split of a second, damaging your TV's switching power supply. The TV's power supply is bad. it cannot produce the proper voltage to power your TV. thats why its on standby. Bring it to your dealer for proper advice on the status of your TV.

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.

Green light blinking


These all sound classic to power supply faults. Or, there may be a board that is pulling too much current due to something that has failed, and the power supply is in the protect mode.

You have to have the service rep check the set.
