If your power inverter is putting out voltage to the main circuit board, then you have a good chance of a faullty y sus board. If you have no power to the main board, then the power inverter is the main cause of the problem. They y sus board may also be tested with an ohmmeter by testing the continuity of each component like capacitors and resistors on the board itself. A service manual would be helpful for this.

Sounds like a failed or at least failing power supply / power board inside the TV. Unfortunately this is a very difficult repair, and unless you are an electrician I would not recommend attempting it. You will need to contact a local TV repair person in your area. This is actually the most common problem with this type of TV, I see it every day, it just happens - sometimes with new TVs and sometimes it takes many years for it to happen.

If you think it may still be under warranty please contact the manufacturer to file an RMA. If you happened to purchase the TV with a major credit card (not a debit card) there is a good chance it may still be under the free extended warranty most credit cards place on electronics. Please contact your credit card company to inquire if they do this, and they will be able to file the claim and get you a refund for the TV.

If you want to attempt the repair yourself please let me know and I will get you the part number and a place you can purchase it from for what you need.

So sorry that I don't have better news but it is definitely a power issue internally.

Thanks
Tim

    Wow I don't think it's going to be worth it to repair. The power board for that TV is $664 online.. and the install will be at least an hour of labor, you are looking at roughly $800+ to get this unit fixed, you can replace this TV for less than $400...

    Thanks

I have a sharp aquos lc-c4677un its not turning on at all now. When I push the power botton on the tv, the power light turns on and about 2-3sec the power and opc light start to blink and thats about it.


How are the power and opc lights blinking? Do they blink simultaneously or does one blink then the other? How many time do they blink per second? Also have you had it fixed yet? and if so what was done? I had a similar problem with my set.

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.

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)
