“Distorted speaker - is it a TV issue or signal issue? Frequently when I watch cable (Xfinity HD) I hear a little distortion in the middle left speaker, but not on the right side. As this is an intermittent issue and its clear that the speaker isn't "blown," could there be something wrong with the tv? Or would this be a signal issue? It's hard to believe a signal could produce distortion on one side of the TV and not the other. I do not play music or any programming at very loud levels, so I find it hard to believe that normal use could cause this so quickly (owned for 3 months).”
