Cannot operate CD

When the player was playing a CD, it suddenly sounded like a motor trying to operate against something jamming it. We could not stop the noise by turning off the power. We finally pulled the plug out of the wall. In trying the unit later, there was some more jammed motor sound and then the CD player does not work. The door does not open. I removed the side covers and released the from door and removed the disks that were still in the shuttle. Still no response. I can run the FM radio, I can push the CD# buttons and the number shows up, but no mechanical shuttling to run that CD. What next? Punt?
