Does the motor make noise? If it does, you may just need to hold the button and press kind of twoard the buttong on the front of the magazine.
If it doens't make any noise, you may not have power back there. I'd check that it comes up and says "no disc" on the head unit.
If it's just fried, let me know. I've got an extra one I'll sell you.
