The sound to my 52" box TV has gotten out-of-whack somehow. The sound is all bass and treble now. When you increase the volume it increases the bass and treble and has a deep and muffle sound. I have played with the menu setting for the audio and have not been able to get back the right setting. Right now I have the bass and treble turned all the way down and the "surround sound" turned off.

What can I do?
