I have 30" Philips HDTV, at least I think its 30", but may be a 32". Either way, I am getting an annoying crackling from the speakers, particulary when viewing HDTV programming. I have a Scientific Atlanta HDTV DVR Combo box from the local cable company. I am an AV neophyte so that's the only information I can provide.
Does Any one have any suggestions to alleviate the crackling?
