it could have over heated you can try to reset it first unplug it for about five minutes and try to turn it on if that dont work the remote might have a set button try holding that down until the red light flashes twice, then turn it on if not then hold the power button down on the set for a good five seconds to see if that resets it. if none of that works you will have to go to panasonic .com for the reset instructions.with the red light blinking the power supply is most likely good you just need to reset i.

SOURCE: Panasonic Plasma TV blank screen

One of the circuit boards, possibly including the power supply has a critical failure. The power supply is in the protect mode. This type of set is serviced by board swapping, and then doing the necessary adjustments to match the new boards as required.

It would be best to call the factory authorized service for a quotation.

If the set is out of warranty you may find it fairly expensvie to service.

SOURCE: I have the same problem Panasonic Plasma TV wont come.

Alot of times capacitors on the power supply circuit board will go bad. They will bulge/dome or dry up which will cause this problem. Bad caps dont hold a charge, which is needed to maintain a voltage. The circuit board is two sided which makes replacing the caps difficult, and the board can be damaged and have to be replaced. Taking it to a repair shop may be cheeper and safer then doing it yourself. Having two-six caps replaced is a lot cheeper then a new board.

How do I fix the problem with my TV? Details are below.

Normally on the Panasonic tv this will call for a service call. The key to getting it repaired correctly is to check for a certified Samsung repair shop because most of the parts come from Samsung. Now if you want to do your own research call to 800 number for Panasonic Tv see if there are any problems with that model that the manufacturer has extended but does not post. I had one repaired that the red light on also so I understand and it went out approximately 4 3/4 years. If your in the Atlanta area use Norman electronics they have repaired hundreds on tvs for me due to my work.

I have a 1 1/2 year old Panasonic TC-P42U1 plasma tv. While watching a show, it suddenly shut off and won't come back on. What do you think caused this and how can i fix it? Thanks.

Try unplugging it completely for 30 seconds to 1 minute. Plug it back in. If it still won't come on, it's likely taken a power surge and popped a fuse or power supply, which means a trip to the service center.

We Have a plasma 42 in panasonic tv that is less than 2 years old. It suddenly popped and now longer works Do you have any advice on how to troubleshoot?

i would contact panasonic and complain that you bought an expensive electric device that should have lasted longer than two years. You might be suprised at how accomodating they can be. Just quote consumer rights to them and dont take no for an answer

Panasonic plasma TV power indicator light keeps blinking, no picture. Does not respond to power on/off switch.

How many blinks is the LED showing? The number of blinks correspond to a service code so that technicians can better diagnose the faulty component inside.
I'm doing factual research for a potential class action lawsuit regarding these "blinking lights of death" problems that the Panasonic plasmas are showing. I'd like to hear more about your experience. It's been a while since you've posted here. Have you contacted Panasonic? If you're willing to share your story with me, please email me at

Just bought a Panasonic TX-P42G10B 42in 600Hz Full HD with freesat HD built in. We currently have Sky +, but i was unwilling to pay the extra a month for the sky HD service. Therefore this tv seemed fine....

Use a good quality scart leads for starters.
connect oon end to tv and the other labeled tv on sky box. The other is labeled vcr. connect another lead from vcr or dvd to that connection.
If you have a hd dvd player or Bluray, then buy a HDMI lead and connect straight to one of the HDMI inputs on the tv. I know this is late but i hope it still helps you and anybody else who may read this.

Cannot tune -in my panasonic vcr. it plays tapes but will not record. I have wired together the tv, sky box and vcr in what seems the obvious way (and every alternative) but no joy so far. can you help?

The main aerial goes into the vcr,a fly lead then comes out of the vcr into the tv,a scart lead from av1 on the vcr into the tv.If you want to record from sky and the vcr has two scart sockets then connect a scart lead from the sky into av2 on the vcr,when you record from sky you select av2 on the vcr as your record channel
