Philips Cdr 765/17 Dual Double Deck Cd Recorder Dubber Burner Player

Picked up this unit from an estate sale. Tested for power and playback. Both trays open fine. Left tray has playback when testing it with a CD. Tested audio from the headphone port and I hear it loud and clear. Right tray is unable to read disc. Hopefully an easy fix to the right buyer. Selling as is for parts or repair. Not offering returns.
