    Hi I am in Australia and having a similar problem. I have a TH-42PZ700A (not recognized on your forum) that is only a week old. After working fine we tried to start it and the light flashes green as if for a normal start up. Then there is a split second of sound and the light changes to red and flashes in a repeating 7 flash cycle.

    We have tried turning off for over an hour. We have tried an alternative power source and holding down the chanel change button. We have also tried not using the surge protector and plugging directly into the wall socket. Finally we tested the power outlet and surge protector and found it to have a stable power supply.

    Any other suggestions or explanations would be greatly appreciated.

    Very similar problem, TH-PZ77U, brand new, has not yet "worked" as every attempt to turn it on has it come on for maybe 2 seconds, appear to work then shut down on its own. Red flashing series of 11. Have tried disconnecting all peripherals, connecting in different configs, totally removed and plugged into different electrical socket ... all with no success. Have submitted questions to Panansonic technical support but of course nobody is working the weekend. Stressed to see so many internet posting of similar issues. Paul in Cambridge Ontario

    Using the remote to turn the unit on, for a second the sound came on. after this no picture/sound. 7 Red blinks on the power indicator...

    Unplugged from the surge protector, direct in the wall and back again all with the same result. No picture/sound - just 7 red blinks.

    It will be serviced within a few days/warranty.

    However, reading that I am not the only one that experience this problem and as there seems to be a structural problem wondering if this 'brand' is wrongly marked as the "number one."

    thanks for this opportunity,
    best regards

    Hi, we have a similar problem, tv (42" viera full HD) is less than a week old - worked fine for 2 days after installation, then switched on today and got the green light followed by red flashing light, but 11 flashes. No images/sound at all. Have tried resting it for 30 minutes, unplugging from surge protector socket/changing power sockets, also the holding in power button solutions suggested. Help! The number of other posts is worrying - not sure if I want another one, this is my first plasma. Jo, Queensland.

    My TV was working fine and hour ago. I turned it off to run an errand. When I came home and turned it on, it did the split second sound on followed by nothing with the power light blinking red 7 times in succession. What a bummer.

I ended up returning my TV to the store I bought it from. Apparently the 7 flash sequence (at least here in OZ) means that the power module that regulates the power supply inside the unit is faulty and therefore as a precaution the TV will not start. Apparently this occurs in around 2% to 5% of all units. While under warranty the unit should be replaced by the seller - after warranty then you will need to pay for a service rep to repair it.

When the power light blinks the set's protection circuits are causing the unit to shut off and blink. The series of blinks is an SOS signal that a servicer can decode to help diagnose the problem.

For those in areas other than in the US, I can't really say what the issue might be as the SOS patterns may be different for different countries. But, if you can find a service manual for your area you should be able to at least get an idea of what might have happened to it. There's no guarantee that what you read is the actual problem without further testing, however.

Hello, found a solution (see our problem above), I hope, touch wood, everything crossed. We had red light flashing on 11 time sequence - unplugged tv from mains for about an hour, then plugged back in and miraculously it came on. TV is obviously more canny than we though it could be. Could this a cautionary measure due to a small power brown out/drop? I know we are in an area prone to them (and surge protectors don't help). Anyway, wish us luck it doesn't happen again. We had a nice night listening to music in candlelight instead!

I had that problem, but with 10 blinks of the red flashing light. Solution was to press & hold the power switch on the TV -- that resets the switch & then it worked again. Will be watching with my fingers crossed & will keep the box just in case.

Not sure if this helps or is relevant, but I just had the same problem. I had the plasma plugged into a power bar when I experienced the red flashing light/no power issue. The problem seemed to correct itself when I plugged the plasma directly into a wall socket.

I had the same thing happen with another one of these screens. Try and unplug it for 30 min and plug it back in. I did this to another screen and it has worked ever since. Let me know if this works for you

We have the TH-42PX70A which has the same problem. It comes and goes..It is only 2yrs old, warranty has run out. The moving red pixels are on the black and the cyan pixels are on the white. It will go away for months and then return for a few days. It is not an antenna problem as the signal is still there.I am taking it in today for the tech to look at, but I turned it on this morning and it is fine. So I wont be able to show him.. (took pics though).Everyone says they are the "best" and all that, but every now and then you get a lemon. If it turns out to be too costly, I will buy a new one and it wont be a Panasonic.

Viera Plasma


hello, if you have a waranty for this tv dont wait take it back to the store for a replacement or repair. contac panasonic for details. they offer a free in home repair service but only if your the original buyer and the set is still covered. this is a not easy or a user repairable situation it is a circut shutdown cuased by a fualty power supply or bad internal board, blinking lights mean theres a shutdown circut preventing full power up panel status.11 blinks pana (th50pz77u) = pb board bad or fualty
since the pb board is a small part it may be a quick fix for a service tech and may not be as much as a power supply or other internal board.
in one of my panny service manuals this 11 times blinking indicates a bad pb board this controls the fans and feeds back to the other other circuts if it is bad it cuases the blinking fualt.
blinking times indicate what is wrong with the tv..
since i dont have your model number i cant tell you specifically if this is the problem, the pb board is one of the smallest internal boards . this info is from a service manual for (th50pz77u)
what is your model number?. the tv is blinking this means it is in need of service it is still repairable. sometimes components you pluged in the plasma may cuase fualts
also if your power outlet is not properly grounded or is not correctly wired you may get trouble. there are 12 diferent blinking sequences from 1 to 12
generally a service tech can come out and check it for you and may be able to fix on the spot. if you have a waranty your doing great if not try a service that offers free in home estimate there are many who will give you a free in home estimate and compete for your business..

hope this helps good luck
