how old is your plasma TV? try check the switch / volume of the sound settings.. Sometimes, when you always increase the volume, it will tend to alter the limit of sound and causing the sound to provide sound undesiredness. I suggest to check it with a liscensed technician.

Check the +170 volt test point on the power board (not the power filter board, the one that the plug comes into) but the one to the right of that board. It has a 5v test point (TP +5v) , a +170 and a +70. I've found that the +170 transformer goes bad, and won't allow you to adjust the voltage using the pot screw.

If you are using HDMI output could be a bad or cheap cable.
I had same problem, tried another HDMI cable and all OK.
