    The night before, the tv was working fine. Woke up next morning, power and OPC lights flashing: both lights flash once and then power light flashes twice. Called Sharp customer services and they told me that if thos lights are flashing, something inside the tv is broken and you got to get it repaired... we'll see what it is...

    I have the 46" Sharp LCD TV.  Worked fine, beautiful picture and sound ... but a few times, I've put it on first thing in the morning - the power light went on, but the OPC didn't ... and the screen was blank. It took me 15 minutes to get it back on again. Wondering if I should return this before the 30-day policy is up...

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!!!

I've read online that upgrading to the latest firmware sometimes resolves this issue. That's kind of shooting in the dark though - I personally would not feel completely confident that a FW flash would actually resolve the issue (as it could still be lurking beneath somewhere, waiting to surface again). If you have no warranty, then the FW flash is not a bad option. It's relatively easy and virtually impossible to screw up!

Another option is to order a replacement (new or used) main power board, and swap it into the TV (or pay someone to do it). It seems the power circuit board is a common culprit for this issue. If you're a do-it-yourselfer, then open up your TV and see if you can tell which component is failing, then hit eBay for a replacement:

http://shop.ebay.com/?_from=R40&_trksid=p3907.m38.l1313&_nkw=sharp+power+board&_sacat=See-All-Categories

However, if you're still under warranty, then I imagine you've figured out by now that your best bet is to contact Sharp to fix this issue. Mine was luckily under the extended (15-month) factory warranty when this started happening to me. I was 13+ months out from date of purchase. Sharp support confirmed a tech needed to come out for an all-day appointment to troubleshoot the TV (I have the monstrous 65" Aquos). Thank goodness for the extra 3 month warranty I got when signing up for the Aquos Advantage club! Otherwise, my $3400 investment might have cost me at least $700-$800 to stay online - only ONE year out from purchase! If I would have known about the frequency and common nature of this problem, I would not have hesitated on buying the additional 3-year protection during my first year as an owner. Now I know to research product defects a bit more before opting out of a warranty for a multi-thousand dollar purchase!

In any case, I'll post the root cause of my issue (same symptom - OPC and power lights flash three times, then pause, and repeat indefinitely until TV is unplugged), once the Sharp tech leaves my place this coming week. Keep in mind that my root cause may not be the same as yours, even though the error codes are the same. :)

Good luck with your issue!

The solution to this problem ...and i think most of everyone's problem is that when purchasing a set ,you do not get certain help documents to ensure your not just messing something up so a tech is needed , with that said , you need to update your firmware (software). this may sound dumb ,but it works ..get a flash drive (2g and under).format it in a FAT partition only.no one has been informed about this unreleased info ..copy your files to this and go by the manual ..this is failsafe .

I had the same flashing power/opc light problem, with my tv freezing and going black. My signal is OTA via an antenna. Turns out, channel seven was the only one having the problem, so I'm assuming there was a problem with the signal. I've also periodically had problems with channel 9. Try another station.

I have two Sharp flat screens one is 2.5 and the other 3.5 years old. Both died last night. We were at dinner and came home there was a storm while we were out. We have a third TV and it is fine. We are unable to turn the power light on both of the sets - dead. We bought a new TV and it is working fine where the dead was placed. We have ComCast cable and did not have a cable box. What do you suggest - should we put them into the trash or try and get them repaired.

TV wont turn on. No sound or backlight. The OPC and Power LED's flash in tandem but when the power button is pressed it wont turn on.


There is a problem with the standby section of the power supply. A flashing standby light indicate an overload which is caused by a shorted semiconductor in that circuit. It's fairly simple for a technician and should not cost much. You can't do that yourself it is electronic takes a long time to grasp.

1 Answer

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)
