I've fixed a few changers. Unfortunately not that particular one. Usally what happens is a cd pops out of place and causes the whole works to jam. I would offer to fix it for you, but I'm not in Kansas Toto.
However if you are brave you might pull the cover off of it and see what's going on in it.

Whatever you do DO NOT FORCE anything unless you are willing to buy a new deck.
If you just want to replace it, check this site:

By the way, I love to tear into things like this so if it is a lost cause get ahold of me.
