Viera Plasma My Viera 42'' is new , just one week old. Today when i try to turn it on, the red led kept flashing, but no images come on, it all black as if its off . Can you please help me to find a solution ??? cheers Bruno Television worked fine for a couple of weeks. I unplugged it to re-wire all cables but when I plugged it back in, it comes on and works for two seconds then shuts down with red blinking light 11 times sequence. Tried pulling the plug, removing the power strip, holding the power switch - problem still the same.

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

Panasonic 42 inch Viera Pixel Distortion

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.
