The fact that the hair dryer allowed the set to come on tells me you have capacitors in the power supply that are leaky. I'd on the board as C1,C2 etc. The value of the part will be on plastic like caseing example 1000uf 25v. Look for a slightly domed top. That will be the bad ones. When replacing these make sure you put them in the same way as the ones that were in the set. They have a positive and negative lead. If you put it in reversed the new part will explode.

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.

Ok. I got my tv back on.
I pulled off the back cover and found the relay that was clicking.
I have two blue relays next to each other that click when the power is pushed.
I placed a hair dryer over the relays for about a minute.
Once heated up, it only took 4 tries to get the TV to stay on.

It sounds that there is some loose contact with any of the IC heatsinks inside the circuit board. Your TV need a through checkup. It is really a skilled work to do with Plasma displays, as they adopts the latest technology. Even an experienced service tech: too will feel a little bit difficult to reach the exact fault point. In my view, it will be better to contact any service technician in your TVs case. If you do wish to get some ideas about the working of Plasma displays, check this link. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electrical shock! Instead, contact the nearest service center.

No display issue


Red means it is going into shutdown because something is wrong.

It will not come on again until problem is found and corrected.

What is model number and do you have a warranty?

I heard small pop then lost power while watching my lg 50pg20. No red or blue lights on the power switch. What could be wrong?


you are describing a power supply defect. IT may be as simple as the main fuse. I believe the one in this set is a 6.5 amp located on the ps board right by cord connection. IF after replacing the fuse opens a second time you will need to replace the power board.

NO PICTURE, NO SOUND On My Plasma TV.


Should have been 3300 UF 10V caps that were bad? Shouls have been replaced with 3300UF 18V. 50V is huge. If it was replaced with a 50 the polarity may be wrong or the cap it too big to be seated property. Sometimes the caps just dry out and even a normal looking one will be the culprit of no OSD. Are you getting an LED fault code blinking? That should be a red led. Do you hear the relay clicking.? When you replaced the caps did you charge them? Just plugging in the set without trying to power it on for about 20-30 mins. I may be able to help you
