I am so sorry. My browser has crashed. The P-board is a part of the energy sustain circuit. Please post the chat request again. Hope fully I can connect back and pinpoint you to the exact location o the board.

just like crt tv units, plasma are old technology
besides that they use enormous amounts of power and are now a waste of time in repairing
If you leave it powered on , that is alright as the main destroyer of electronics is the constant on/off operation as the temp changes of the components is the problem
However knowing that it uses probably 100 times more power than a led unit, , you are having problems with it and knowing the price of parts , I would recommend considering a newer more economical unit of a quality brand

Hi bschaub796,
10 times blinking of your unit indicated that the processor sense the missing 15v from the power supply. This problem is quite technical since I've already read your post that you have a reading of 15v in P25.
Now, we have to examined it deeply to determine where the fault came from between the two board.
If you have a 15v coming from the power supply but its go to 0v after a while which trigger the 10 blinks, you have to check the feedback circuitry of the power supply for faults. If you can't find any faulty parts on that section means that the feedback circuitry trigger to shutdown because it sense fault in the D board.
Remember that it has a good regulation output from the power supply, the issue here is the feedback circuitry that sense the fault. If you are going to ask my opinion I've suspected that the fault is in the D board.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Hello,
Your power supply board is dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.


Hope this help out in solving the problem, take care

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.
