Have an SA Explorer 3200 that started making a ticking noise a few days ago. TV picture and sound are fine, no problem. The noise is coming from the box itself, not the TV speakers. When the box is off, doesn't make noise. When the box is on, if I unplug the coax cable, the noise goes away. When I plug the cable back in, the noise comes back. And, no, I don't think that it's about to explode, at least I hope not :) Anyone have any idea what could be causing this?

3 - 4 years old. Air flow is good, sits on top of the TV, nothing on top of it or next to it. Not dusty on top or in the vent holes. I opened it yesterday to see if I could spot anything wrong, a bit of dust inside but not much. Seems weird to me that it'd only make that noise when it's on and the coax cable is connected to it.
