TH-42PX60U wont turn on. Blinks 10 times. replaced the power supply board, but the same issue.


What I'm learning is there are several models of Panasonic TV's that have a video card that doesn't play well with HDMI applications and the end result is, you need to call this number and not only make arrangements to replace the bad board,but also this!
Your model doesn't show below,but I'd certinly inquire about the necessity of a "Firmware" update!,,,Panasonic knows FULL WELL they have a HUGE problem here!
Hope this helps!

At panasonic.ca I found the listing for the fw update under customer support-important notices

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.

Panasonic plasma hdtv will not power on--no blinking LED, simply no LED. Other objects plugged into same surge protector are fine; no evidence or suggestion of a power surge.


The power supply board itself maybe the main problem inside the TV. Or, it maybe something simple like a blown fuse. Replacement fuses can be found at Radio Shack or some other electronic supply store.
If it turns out the TV keeps blowing fuses, the main power supply may need to be replaced. You can find replacements at a good price at Shopjimmy.com

I have the same problem Panasonic Plasma TV wont come.


Alot of times capacitors on the power supply circuit board will go bad. They will bulge/dome or dry up which will cause this problem. Bad caps dont hold a charge, which is needed to maintain a voltage. The circuit board is two sided which makes replacing the caps difficult, and the board can be damaged and have to be replaced. Taking it to a repair shop may be cheeper and safer then doing it yourself. Having two-six caps replaced is a lot cheeper then a new board.

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.

Plasma TV - intermittent blinking


Power supply failure. Either a capacitor went bad, or there is a loose solder joint near the big transformer on the power board. I would guess loose solder connection.
