You could try gently sliding a thin blade in the top of the tray slot to hold the CDs down whilst, equally gently prising the underside of the tray with a small screwdriver (it may help to press teh open/eject button at the same time).

Please check the power supply cable to your machine . It may loose or disconnected.

Hello,that unit uses one laser and the tray brings each cd to that laser for it to be read.The fact that a particular disc is having problems leads me to believe the disc is at fault,look for scratches and/or fingerprints on its clear metallic side.

It will work after leaving it unplugged for 40Min.

If you mean Fixya, no it isn't. You can pay if you like, but it's not required.

hit the thingymajiggermabob inside of it with a hammer than it shall work if not get a new one problem solved

Hello

OK, firstly, you are correct. This is most likely a mechanical problem, so, you will need to ask yourself the following questions:

• When you press the eject button, can you hear a grinding noise?
• Does the player make any sound if you press the eject button?
• If there is still a CD in the tray, can you still listen to it.

Now, if the unit does not make any sound once you press the eject button, this is an electrical problem, which means the motor does not get any power to move the tray out.

If you can hear a sound, the motor is trying to eject the tray, and have either slipped of the gear, or the rubber band which is driven by the motor has broken off.

If i may make an suggestion...

If you can hear the motor spinning, i would rather that you take the unit is. I had this exact problem a couple of times now, and had it repaired in 10 minutes for under $5. I am suggesting this, because, if you do try opening up the unit yourself, you might damage the laser lens, which will cause a much more expensive problem.

Please feel free to let me know if you have any further questions.

Kind regards

Use a surge protection power strip (such as the Power Protect AV 600 by Monster Power).

This will elliminate erratic behaviour of the unit, since even minute fluctuations in the power source from unbridled house current will affect the sensitive internal components of the Onkyo DX-C390 6-Disc CD Changer.

Caps in power supply PCB are dry.Changing 10000uf,2200uf,470uf will help.

The little drive belt that operates the CD lift mechanism is likely busted. I just started looking for belts now.

Your going to have to take it apart and manually remove the cd.
To do this remove the top cover.
Make sure the power is off and that it is unpluged when doing so.

Digital or analog output? Try the other - same thing? If it improves by switching outputs, suspect teh cable. Also try moving the output to another input on the receiver (?).

you have to take a screw driver and open it .the push it from the inside

Hi,

You're tray may be opened with a belt, maybe it's slipping over the plastic wheel.

Good luck,
Gerard

almost all the gears in there are plastic and the motors are replaceable. it will wear out after a while. if it is the motor, you can get a replacement from mcm electronics on line. if it's the gears, you'll need to replace the whole assembly.

Hello: Considering the age of the unit, I would say you need new loading gear belt and mech assembly elevator belt. Look inside for any belts that have become to loose to turn pulleys for gears, take off any belts you find and lay on a flat surface and belts that have become egg shaped need replacing, you might also try buying some rubber rejuvenator liquid from a local electronics parts store to restore grip to the belts but new ones is the best way to go..

The optical lens assembly is damaged at this point. the lens has burned out and the tracking/load motor seems to be faulty as well. replace the optical lens asap.

Sounds like there might be a disc jammed in the disc tray.
