    I have a Denon DM39 which has a cd stuck in the drawer.
    I have spoke to Denon and tried to reset it.
    When I push the open button there is no noise. I have had the top off and cannot force it out.
    There are no repair shops at all in my local town, so wonder if anyone has any ideas.
    At worse I just want my cd back for now.
    Thanks for any replies.

    Can you post a picture of the unit with the top off?

    A replacement CD will be cheaper than a repair. It is likely to be either a broken belt or a surface mount fuse has failed. If the unit is dead/unrepairable then breaking it apart carefully is the only option to retrieve the CD.

    Can you see any of the disc with the top off? If so, try manoeuvring it with something like a wooden kebab skewer to see if it's slipped out of the tray.

    U can see an eight of the disc, it’s in the tray perfectly.
    I’ve tried forcing it eith small screwdrivers it’s very tight.
    It’ll still play the cd and the radio so I’m not going to break it to get cd out.
    If it was a broken belt, I thought I would be able to hear the mechanism trying .
    I can post a pic when back at hone

    There are a variety of different tray release mechanisms, in some a little hole forces the tray motor to engage. In others e.g the panasonic dvd player there can be a slot below which can be mechanically moved to force the action... It's a better Google question.

    The Drawer is not going to pop out the way it does when it is working. Likely there is some kind of gear (multiple gears) and motor mechanism. You will likely have to spin the gears and make the draw creep out a bit at a time.

    It is possible that a belt is broken or worn. It is possible that a gear is stripped. It is possible that the mechanism is simply jammed. I think I had this on a BluRay Player, and while I tired to find a replacement belt, in the end I was able to clean the existing belt and put some belt dressing on it, and it started working again.

    So, you have to Trace the draw-open mechanism until you find a point where you can manipulate it and slowly work it open. Generally in the area of the drive motor that opens the drawer.

    Then look for belts that might have slipped off, or be stretched or worn. Alternately look for gears that might be stripped or dislodged. It is also possible that the motor that drives the tray open and closed has dried out and frozen. It might be possible to revive the motor by cleaning the shaft bearings with some alcohol, then simply lubricating the shaft with some fine oil.

    You will soon get bored of listening to the same CD over and over.

    Service Manual here DENON RCD-M39 SERVICE MANUAL Pdf Download.

    Looks like the opening mech uses a belt. If you hear nothing when the eject button is pushed then the possible are, either the button is defunct, the electrics/relays/fuses controlling the motor have failed, the opening motor has failed or the belt has failed and is jamming the motor. If you can hear the motor it is more likely just a belt failure.

    P.12 shows the manual tray release on the base of the unit.

    ..that is the type of mechanical release i was expecting..... Move a plastic knife or a screwdriver with the power off., We don't want a funeral here.

    Is this a good time to mention that this would never happen with a record player? :p
