You have the same problem i have. My Tv just did the same thing 3 nights ago. I unplugged the set, and let it sit ofr about 6 hours, and then tried it again. It turned on and played, but repeated the problem after about 20 or 30 minutes. So far all my research has led me to believe that its a power supply issue. Problem is, there are 5 boards in the tv with seperate pwer supplies, and the 10 red flashes indicate that its all of them. :-(. Im shopping for a new TV, and It wont be a panasonic this time.

I just bought a Panasonic TH-42PZ800U and had the same problem. 10 blinks and the TV would not start. Then after some trial and error I solved the problem!

Here is my (apparent) observation and solution:
I had only one input into the TV, which was my HTPC connected via a DVI-to-HDMI cable plugged into the Panny's HDMI 1 slot. *IF* the HTPC was already on, then the Panny would have the blink of death. *BUT* if the HTPC was off, the Panny booted fine (assuming I cleared the blink of death first by powering off the HTPC, unplugging the TV, and replugging the TV back in with the HTPC still off).

My solution was to move the HDMI cable from slot 1 to slot 3. After making this one change, everything worked as it should. No more 10 blinks of death. I could even leave the HTPC on and turn on the TV last, and it still worked. Tried this 10 times, worked 10 times.

I don't know if this will solve other people's problems, but I hope it at least provides some clues. I wonder if this is a fundamental circuit design flaw on the part of Panasonic, rather than a "bad batch of parts" problem.

Plasma tv th-42pd50u not come on and keep blinking red light two times and then stop again blinking red light two times and then stop not come on


The light blinking twice means there is a fault within the system and it is a code to tell Panasonic where roughly the fault lies.
Go to Panasonic's web site and look for your set then input the fault code and hopefully they will tell you where the fault lies.

My plasma tv is not coming on power light is only blinking


Does it start blinking as soon as you plug the tv in or only after you hit the power button? Also, how many times is it blinking? Count the number of blinks at least three times

TH-42PX60U red light blinks 10 times wont come on


On a Panasonic TV the 10-blink error code can sometimes be caused by low voltage running through an HDMI cable, particularly from a Media PC or some video game consoles. Try disconnecting any HDMI cables and unplugging the Television for 30 seconds, then power it on without the cables attached.

If this works, connect the cables to the front panel (usually HDMI-3) which uses a different controller board.

No power


If your model number is TH-42PD50U, It is very hard to diagnose the symptom.I can direct to you where is the possible cause is.
For 7 blinks pattern may have trouble with SU or SD board or it could be SC board or Power Supply

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.

Power light flashing once


Ouch...ok a one blink code could be either the P (power board) or the SC (scan board)...only a service tech call can tell you for sure. Ask around for some quotes first.
