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.

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!)

It will depend on your video output options on the computer. If you have HDMI output, just use an HDMI cable and an audio cable (this will need to be a 3.5 mm to RCA audio cable). If you have a DVI output, use a DVI to HDMI cable and the audio cable (or a DVI to HDMI adapter and either a DVI or HDMI cable depending on which side you want to put the adapter). If you only have VGA out from the computer, use a VGA to DVI adapter and the DVI to HDMI connection and the audio connection. (Theoretically this should work but each adapter will have some signal loss issues.)
Some graphics cards have a video output, S-video or Component video, which would also connect to your TV with the audio cable. (Read your cards manual for more information)
I hope this helps.

(For DVI to HDMI cables, you will need to check if you have a single link or dual link DVI output. The wrong cable may not work.)
