Sharp LC-32SB21U Opc and Power Light Flash

Mine is flashing the power light and opc light sometimes. It takes anywhere between 1 minute and 10 minutes of powering on and off for it to finally work. I took the back off in hopes to see a popped cap or two but there is not evidence of failure. Has anyone got this fixed and if so how so I can give it a shot.
Thanks Thom

    Thanks for the reply. I did look for any blown capacitors and saw nothing wrong with them. They are all flat. I did a visual inspection on all other components to see if anything looked wrong but found nothing.

It sounds like you have some capacitors that have gone bad or changed value. The place to look is in the power supply boards. Notice the top of the caps have an indented X or V which is really a vent. If the cap over heats it will bubble out a brown residue on top of the cap. The top of the cap is supposed to be flat, if it's not flat but has a dome, replace it. You have to take the caps out of circuit to properly check them with a capacitance meter. Also bad solder joints on the power supply boards will give you these symptoms. Hair line cracks in solder will separate when cold but will expand and connect when warm. That's why it may start working after it's on for awhile.

It is a common problem for this sharp model, the problems is weak back lights tubes inside the panel.

Usually the screen has pink colors first, then the stand by lights blinks 3 times, your TV will not power up.

Please change the back lights tubes, sharp part number:

How can I get the TV screen to come on when only the power and OPC lights flash?


Even when the TV is off, some electronic components in your TV consumes power 24 hours a day. Maybe a power surge damaged your TV when the power came back on.

I originally purchased a LC-32SB24U and wound up needing a replacement because there was a black line going accross the top of the screen. Sharp didn't have any of that model so they sent me a LC-32SB21U...


Don't feel bad. You didn't do anything wrong.
They sent you a TV with a bad power supply board for the
screen. The TV is trying to power up the screen, but it can't. Because of a defective part somewhere on the power inverter board for the screen. That is why the power/opc light is flashing.

I would call them back and and make them replace the TV.

No POWER


How many times does the POWER led flash per second? (Dont worry about the OPC).

1x (steady constant blink) = Lamps or inverters
2x = Power Supply
3x = Main Unit

If i am reading it correctly, looks like the POWER led is flashing 2x, which means it is a power supply failure. Either way, your TV needs to have a board replaced, there isn't anything you can do to fix it yourself. Try locating your local sharp authorized service center to repair your TV (1-800-237-4277)
