CD tray won't open and motor running

the little motor band is faulty try to hit 2 or 3 times on top when you are pressing cd open

tip dont hit too hard and and pay attention if you can ear the tiny motor running trying to open tray

The small belt underneath could be broke

if you have 2 tiny screw drivers, if not, the tips of a butter knife might be skinny enough, you can try to insert them a wee bit into both sides of the tray and pry outward, carefully of course, and unjam the tray

Sure that the outlet you are using is powered? Is power reaching the motor? - I had my power switch on my karcher break internally rendering machine dead. If power is reaching the motor for sure and it does not run then there has to be an open motor winding. If pump jammed you would hear a humming noise from motor and the breaker would pop.

I'm inclined to think that your power cord is bad and you have drained your battery.
When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.

the rubber rope which conect the motor to a small gears to open the cd was cut due to long using ... this sound of clicking coz the small motor is running and its not attached to anything ... its a small rounded rubber rope ..the bad news is you have to break some plastic stuff to reach the motor in the repair depot they change the whole upper part so it costs alot ... but if you can reach it it will work perfect as its new.

It two things can cause this:-
The motor is damaged ( you can listed closely to hear if the door motor runs when you try to open the tray.
Or The belt that takes power from motor to open mechanism is damaged.

This seems like a very big issue. Try contacting Denon for a solution.

More than likely a belt which runs from the load/unload motor to the CD tray. Replace this and everything should work. I've done dozens of them. Unless you are pretty handy with electrical components I'd recommennd a repair shop. A straight forward repair If it's the problem I described, about 40 minutes work if that.
Just make sure there isn't a disk caught up at the rear of the tray. If you are missing a CD that's possibly where it is. That could be stopping the tray from opening.
