Firmware update


Your tv will update firmware automatically, it may warn you not to shut it down during the process. However having said that if you go into your main menu, you will see a first time startup option, follow the links and you will see an option to "update firmware" choose this option and it will update. Hope this helps

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

Won't respond to volume or channel changes red light blinks 20x's when turned off.


It's definitely a firmware problem. I called Panasonic and they were very polite about the entire situation and sent me a SD card with the firmware update. If you don't have time and you're tired of listening to tv at the same volume there is a way to do a hard reset.

I figured that unplugging the unit would do this, but there is one other step that you have to do to ensure that this works.

Generally the power button on the tv is always in the "on" position, this is what allows the remote to work. In order to do a hard reset the on/off button must be in the off position. Make sure that is off, then unplug the unit, let it sit there for a minute or two and plug it back in. If the tv comes back on as soon as you plug it back into the wall/powerstrip then the button was not in the off position.

This isn't the best fix, you'll still need to get the firmware update but it will at least give you the ability to use your tv normally....well until it decides to randomly lock up on you again and you have to do this all over.

Tv does not power on


If it blinks 7 times, your power supply is shot
If it blinks 10 times, a video board went bad.

PANASONIC TH-42PD60U


I had a similar problem where my TH-42PX60 would turn on but all controls were disabled. I could not change channel, input, volume or anything other than turning the TV on and off. I called customer support and they directed me to this site: http://www.pasctraining.panasonic.com/specialapplications/productfirmwaredownloads/downloads1.asp to download a firmware update onto an SD Card. I inserted the SD card into the slot in my TV and powered it on. The update took about 3 minutes and I haven't had a problem since.
This is a link to the instructions to install the update:
