Our Sony TV sometimes won't come on when the switch on the tv is pressed. Weirdly, if we switch it off at the wall socket, wait a few seconds, then switch it on at the wall socket again, the tv switch then works......
Don't understand why this works, but if it gives you a work-around, it would be a lot cheaper than a TV engineer's visit....

SOURCE: red led flashes. when i try to turn tv on it shuts

There should be a number of flashes that you can count. This is an error code. It will flash a number of times and stop. Again, Flash a number of times and stop. Contact a repair shop that is familiar with panasonic and have them to check it out.

SOURCE: sharp aquos lc-37d43u tv

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!

SOURCE: Panasonic 32 inch LCD TV will not turn on-red light flashing

This is a known fault. John Lewis in the UK sent out an engineer under their 5 yr TV guarantee and completed the firmware upgrade for me. The only other store to compare with them for price and service is Richer Sounds but I believe you now have to buy the warranty for 10% of the purchase price. This problem will persist unless the upgrade is completed. For those of you in the UK, I would insist the seller repairs the problem under the Sale of Goods and Services Act as the TV is not fit for purpose without the upgrade. You have 6 yrs (not a year or 6 months) to claim under this Act.

I NEED HELP WITH CHANGING CHANNELS,PWR,ETC/...I HAVE A PANASONIC TV


The TV codes for a URC-3021 and a Panasonic TV are:

0051, 0250, 0650

These are the steps to program your remote:

To setup your URC-3021 for a VCR, these are the steps:

1. Turn on your TV.
2. On the remote control, press TV once.
3. Press and hold SET until the LED (red light) blinks twice,
then release SET.
4. Enter the first four-digit code for your device. If performed correctly,
the LED will blink twice. If the LED did not blink twice, repeat steps 2 through 4 and enter the same code again.
5. Aim the remote control at the device and press POWER once. The device should turn off. If it does not, repeat steps 2 through 5, trying each code until you find one that works.

1. Press tv on your Sky remote control.

2. Press and hold down select and the red button together until the red light at the top of your Sky remote control flashes twice.

Then enter the remote control code using the number keypad. The red light will flash twice if a valid code has been entered.

Panasonic Code: 0051

4. Point your Sky remote control at your TV and press the Power button. If this turns the off as you'd expect, then the tv should be set, press Select and the remote should work

5. If the TV does not turn off press tv, then press the Power button again, repeat this process until the TV turns off, when the TV turns off press Select.
