Pan Camera stuck in one position

My pan cam stopped panning – I only hear a grinding noise over the audio link. Tilts up and down ok.

I checked my camera last night; it was pointing in the right direction. When I looked this afternoon, it had moved on its own (sometime overnight, and without being commanded) and is now facing the wall. At this point, it won’t move in either direction. I’m away from home, so I can’t do anything about it at this time. Great view of my wall, but otherwise useless.

Has anyone else had this problem? Is it hosed, or can I fix it?
