    Same problem, no response to pushing the power button or using the remote.  Changed batteries in remote and tried unplugging the tv for a while.  Nothing

    I have the same problem. Sharp said I have to take it in and pay for repair even though they know many people are having the same problem. Too bad Canon doesn't make tvs... I have a Canon camera and it had a problem and Canon is fixing it for free.

    My Sharp 32" flatscreen tv that I bought less than a month ago won't turn on. Power light and OPC light blink and blink and blink. Even though i got the warranty i may just return it and get my $600 back instead of getting it fixed or whatever.

    Screen flashed, went black, then came back with sound, but image was nothing but multiple vertical lines. Turned off TV, waited, turned it back on and no picture OR sound. Going to try and get it replaced. TV is less than 4 months old.

This is very common in sharp tvs.U turn it on.U get power on light stable right?U hear a click,one or twice,sometime tv is good right?Sometime POWER light and OPC light flashes?Push the power button on/off couples times will work, picture will come on.If keep trying off/on couples time after POWER and OPC flashes,don't ever stop and never get backlight and picture.Ur Video backlight board is dead must replaced.

SOURCE: 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)

This screens are all but impossible to replace.You only have a couple of options. 1. Buy a replacement screen for the television manufacturer 2.Find the same make and model of television with the screen intact and purchase it. This can be done by watching websites like e-bay and craigs list for these items. You can go to the websites and use their search engines with the brand name and model number tofind the televisions or the parts that are for sale. If you can find the part number of the lcd screen. You can try to locate the lcd screen maker and buy the part from them. By far the lowest cost alternative is to find a television with other problems, that is not repairable and buy it and use the parts. You can also look for it in local newspaper ads and yard sales. I hope this information helps you with your problem.

SOURCE: will not power on, like others have had issues

Flashing power and OPC (OPC is for automatic brightness control that adjust the brightness according to room light) flashing means you have either thw power supply module or the backlight inverter module problem.

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.

What is OPC flashers on screen sometimes


Same problem. TV worked night before and then would turn on but no picture or sound. Power and OPC lights blinking. I couldn't change the channel or get to the menu.
I disconnected the coaxial cable and the power for a few minutes and then plugged it back in (electric) but left the cable off. I got a message that it couldn;t get a signal. At that point I was able to change the channels. I plugged the cable line back in and everything worked fine... Good luck!!!
