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:

SOURCE: Panasonic TH-42PX60U plasma TV: red blinking light

are you using a PC to feed a signal or maybe a cable with an adapter?
I had the same issue when I used one of the rear HDMI ports to show a PC display. Apparently there is a software difference between the rear and side/front ports. Inputting the PC through the side HDMI port has solved the problem for me (so far!)

SOURCE: Panasonic TH-42PD50U RED ON LIGHT BLINKS BUT WON'T STAY ON

Normally, when this happens, the TV goes into " Protection Mode " because of a failing circuit board. Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. The most common thing to go out on flat panel TVs is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.

You have a few choices:

1. You can try leaving the TV unplugged for 30 minutes so the TV can reset itself.


2
. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light blinking codes, circuit diagrams, test points, and part# lists. Usually, cost under $20. And most cases the new part cost less than $15.


3. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.


I hope I shed some light on the subject for you.

SOURCE: Panny TH-42PZ80U Plasma TV No display on Power-up

I had this same exact issue. Panasonic sent a repair tech to my house since I was still under warranty. The tech was able to fix me up in about 10 minutes. He replaced the "brain" or A-board and now I'm back in business. This is NOT a power supply issue. The brain is the circuit board that has all the inputs attached to it (component, hdmi, etc...).

hope this helps!

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.

Panasonic TH-42PX80U won't turn on.


You are missing 15volts. If this is a new TV, it could be as simple as a plug not fully seated on the power supply. Regardless, the repair should be covered by warranty and Panasonic is one of the best when it comes to taking care of the customer. Ifd nI can be of further assistance, let me know
