You should call for warranty service. If the set is very new try to get it exchanged.
There are some very heavy duty power supplies and many high power matrix drivers used in Plasma sets.
The description sounds like the noises are very loud. It is normal with any of these TV sets, if you put your ear right up to the back of the set at the vent holes you will hear some noises. These would be some acoustic harmonics from the power supplies and related circuits.
I am wondering if it is possible that there is something that is becoming less stable. If the set is working very well without any failure, so-far this is a very good sign. Before it gets to be a problem, I would have this checked.
On many models of these sets, they use fans for cooling specific areas. A bad fan can cause noise.

I bought the model TH-50PX60U June of 2007. I've been hearing the very annoying clicking noise as well.
Since the TV has a one year warranty, I just called Panasonic and they've scheduled a tech to come over and take a look at it three days from now.
I will publish the results on the same page.

If the red power LED is blinking 3 times--it is most likely a shorted convergence IC---the only way you can be sure is to remove the light box--I can tell you how by email--and unsolder the two STK-392-110 ic chips----they are on two heat sinks made of aluminum next to each other; if you open the back cover and find them you will see about a dozen blue(light blue) resistors marked 2.2 ohm----if any of those are some what white in the middle(discolored) they are gone and the set will never adjust until you replace them and the two convergence IC chips---What I usually do in this case is remove the light box and unsolder both IC chips and plug it in and turn it on---if the set now comes on and stays on--I replace the IC chips and adjust the set---I have done hundreds of these sets---3 blinks is almost always a bad convergence IC--if this was helpful give me a vote---AND IF YOU NEED DIRECT ASSISTANCE contact me at:
