SOURCE: Panasonic TH-37PD25 plasma has no sound

If all of your connector cables are in good standing and your input/output ports are hooked up correctly, this may be an audio defect developing in the processor board. I can walk you through some steps to confirm this problem.

SOURCE: Panasonic plasma TV model TH-42PD60U won't turn on

I had this problem in 2007 / 2008 here is what happened to me. Jan 09, 2008 - I also have brought the unit to the authorized Panasonic repair facility and the problem is a failure in the P-board which is the power supply board. The P-board needs to be replaced. The repair will cost $475 plus tax. $250 is for labor. The unit was nop more than two months out of warranty. This does not speak well for Panasonic. I have been researching the problem and it looks like this has happened to many of the Panasonic plasma TVs.
Jun 14, 2008 - As an update to my problem with the failed P board. Contacted Panasonic Service and talked to a customer service representative. I told them how I have purchased many Panasonic products and how unhappy I was with the failure of the product. They proposed paying the labor cost of $250 and I would pay for the part. I just hope it does not happen again.

SOURCE: TH-42PZ80U Panasonic Plasma, red light flashes 10 times

Panasonic said "A" board,
A board SOS Detect (Explanation)
10 Blinks SOS: The voltage regulators IC5400 and IC5401 in the A board generate SUB9V and SUB5V. The 9V and 5V from these ICs are monitored by IC1100. Any abnormality on the SUB9V or SUB5V lines, triggers the shutdown circuit and the MPU shuts down the unit. The power LED blinks 10 times.

But need to measure the connection SC2, if it short, it will be the SC board.

The knowledge obtain from: Real case of repair by myself.
Information from Panasonic training manual.

Try disconnecting all HDMI cables and plugging the TV into a new wall outlet. If the issue is resolved, it may have been caused by a small power surge from either your wall outlet or one of your source devices.

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?

Panasonic th-50px75u


I assumed your TV is either wall mounted or in a tight space with very little room behind the tv??
Panasonic.com, click on support and find the nearest authorized repair company to fix your TV. It is not going to be cheap.Should be at least $900 and up.
Good Luck,
