Reset Problem
Changer won't work. I had to pull it out and open it up to remove the casette and get a CD out. It seems to be a mechanical problem. It seems to be jammed up inside. I've seen others questioning the same thing, but haven't seen an answer as to how to fix it. Just pushing reset doesn't.
