Question about Televison & Video

1 Answer

I have a Panasonic Plasma Flat Panel HDTV, Model TH-50PZ83U. The tv is not turning on properly, and has a constant blinking light by the power button. It blinks 10 times, pauses, then starts to blink 10 times again. Panasonic support could not offer much help except to guess that the power supply needed to be replaced. Of course set is out of warranty. Do you know if Panasonic is able to fix this? I read in another note on this site, that Samsung was replacing the capacitors on the power supply board, although I am not sure if this is the problem. Please advise. Thank you.

10 blinks is common on this model.More often this problem is not associated with power supply as you might have seen in Samsung. There is no recall for the same. You could seek a goodwill gesture from Panasonic of your TV is few days above one year.However, this is only a request that might or might not be taken care of.Unplug the TV for few minutes, say 15 minutes and then turn it ON.If the problem persists, then it confirms a hardware failure.

well 10 blinks means you have a short circuit on the 200V line
This powers the Y-sus board the Z-sus board and the Y up/down buffers
So any one of them could be bad
the first thing i would do is remove the upper buffer detach from the SC or (Ysus) Board
and see if the 10 blinks has gone away the tv might even stay on
and give 1/2 picture if this board was bad
if no change then
remove the lower buffer if the 10 blinks has gone away
then replace the lower buffer as it was the problem
if no change then unhook the ysus SC board
and then the Z sus board if all those boards are out and still 10 blinks you have a bad power board
other wise what is bad is the last board you pulled out and the 10 blinks went away
the tv will not provide a pix with these boards out but if there error goes away you found it
If that is too much for you
go here and find NESDA authorized Panasonic Servicer

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

My panasonic model #TH-50PX75U wont turn on, it powers up but the led light stay on not blinks any time.

Unplug the power cord. Press and hold the power button for 30 seconds, repeat. Plug it back in and try to turn it on.
If this doesn't work, it would be time to call in a repair tech. Is the TV still under warranty? Extended warranty?

Your TV is in protect mode. A problem was detected and the set shutdown. Is there a pattern to the blinking?

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.
