I've had this beast since 2001 and it's been collecting dust since I've been in apartment after apartment until now. I hook it up and it's working great for the past two weeks until now. I had to reach behind it on the floor for something and knocked the cable from the volume control to the subwoofer... ever since then it plays no music. I haven't smelled anything foul such as anything burning, but again no music. Any other speakers work fine.   I'm not sure what to...
