Commonly these changers use a single CD reader, maybe you only have a dirty optical pick up, to be more specific, the lense part has dust or another optical interference, then you could try with a good CD lense cleaner disk/ kit, in the worst case, the optical pick up is bad, but don't worry about, it can be replaced.

It's capable of playing MP3's right out of the box. See page 18.

Had a similar problem with my Denon. When I inserted CD it takes it in but immediately stops - like it doesnt sense the CD. Same problem with Single or Multi changer. Removed cover, removed reader ( 4 screws) and found lens had fallen out. Cleaned, reinstalled with touch of super glue on rim - works fine.

Optical pick up of your unit requires replacement.

If you don't wanna send it for service, open the chassis of the player and free the CDs from the tray. Its highly likely that the CDs came off the trays and got stuck inside.

The disc is loaded upside-down in the disc rack or the disc is dirty or scratched, try another disc and make sure the top side (label side with printing) is facing towards the back of the rack, away from you. The bottom or data side should face out towards the front of the rack. If that does not work then your laser picups inside may need cleaning. Make sure your disc is clean and now scratches.

Simply remove the outer casing and remove the jammed disc
