Panasonic tc-p60gt30 won't turn on. Something hit screen. Screen did not crack but now won't turn on


May have damaged the PDP (plasma display panel) inside---if the panel which is fragile shorted inside it will trigger shutdown.

Lg 42 plasma - loud bang/spark smelly smoke and small flame inside.


It is a short circuit caused by some components and/or power capacitors. This may need assessment by a qualified service technician.

Tv isnt turning on, you will hear a click then see the power light flash 6 times then the light goes off for about 10 mins then comes back on flasing again...and the cycle just continues. It did this once...


Sounds like a power supply problem. I worked for a short period for Panasonic at their USA plasma R&D / small scale manufacturing facility and learned that to "ignite" or start the plasma when turning on the set, a significant current discharge is required.

The recycling seems to indicate that the "brain" in the set realized that a plasma has not been established, and it is attempting to recharge the starting circuit. The flashing power light is probably significant and a trained technician or a service manual will probably identify this as a trouble code pointing to the problem. Sorry, I did not have any exposure to the finished product and cannot advise what the code means.

If the set is still under warranty, you should act immediately and get the problem taken care of, because it will not go away on its own, and will most likely get worse. Sorry the news is not better. Good luck!

I have a panasonic 50" plasma that turns off about


It can be bad power supply or shorted circuits in the sustain boards which will cause the power supply to go into shutdown mode. You need to open it up and inspect those board for bad caps, blown fuses or burnt parts, Most failure in the PLASMA TV are due to bad power supply, failed Z-sustain Y-sustain boards.

Power light blinking 2 times


2 blinks means the unit is having problem with 12 volt supply.
while power on you can check 12DC on power supply before shutdown.if the voltage is constant before shut down I would recommend to replace D board.
