Hi...

I've done work on these .
You need to replace the drawer belt. This requires that you remove the CD assby. The belt is under a thin plastic cover at the front of the CD assby

SBM 3.0 belt at studiosoundelectronics.com
or similar at MCM electronics.

CDC-655 was put in storage (in orig box) and brought back out and plugged in. It loads each CD and fails to read each one. The lighted numbers go out, one by one, as it fails to read them.


Hi,

This seems to be a "Dust on Lens" problem. No issues... It happens when you keep your CD/DVD players unattended for a long period of time. Even if packed well enough, dust/moisture does tend to gather on the lens and cause this type of an irritating problem.

If you have a lens cleaning CD (if not, go buy one) then just insert it and let it spin regardless of whether or not it reads it. The spinning action will clean off any finely deposited dust particles on the lens. Repeat th process till the Lens Cleaner CD starts playing its audio. If this happens then all your other CDs should read. One more thing, make sure that the motor is indeed spinning. How can you know???

1. Buy listening carefully for a whirring sound the moment you put in your CD/DVD
2. By feeling for minor vibrations on the front panel (CD tray front cover)
3. Putting in a CD/DVD with a label straight as you can read it and see if it comes out differently on ejecting it. I hope you understand what I mean...

If this doesn't then it could be a blown lens circuit or a dead drive motor. In that case your player needs to be taken to a service center.

Hope it answers most of your query. Good luck.

I have a numark cdn 88 just change the transport assemble but the cd wont spin and give me no disc on the display


Chances are that you didn't reassemble the unit correctly or damaged a ribbon cable or limit sensor. Re check your work. Pay attention to small circuit board attached to the spin motor RF310T-11400. De-solder the small circuit board on the 2 motors..and apply 12v to the spin motor. See if it spins with no dead spots on start up. when asseembled, motor will only operate and spin up to the proper RPM only if loading is successful and tray is fully closed ..etc. Hope this Helps. I have a CDN-88 in my shop for skipping issues on both CD players. so I saw your problem here while doing research. Good Luck,

Thanks, Dillon, Trace Electronics, Barrie, ON, Canada.

Cd player doesn't work


This is doc-fix. The C D motor is supposed to spin spin, at all times when selection. then the C D record makes selection.
in that sequence.
See if motor spins by finger twirl? Is it turn 3,or 4 turns?
if it is binding on the black plastic, then that has to be corrected. if the motor is getting no power (electric power)
then there will be no spinning. need a diagram , showing how
motor power goes into the C D HEAD TO MEASURE VOLTAGE???

CD PLayer won't play CD's


Hi First of all, you must find all the screws for the top cover and remove it. Make sure the unit is not plugged in! Then, making sure that you are not touching anything inside the unit, plug it back in,put a Cd in the drawer, and watch what happens. If the drawer closes, but you can still hear a motor running, then it is a belt drive unit, and the belt is slipping, if that part is ok, listen carefully for a ticking noise, which is the laser lense going up and down trying to focus on the CD, if the disk starts to spin then the mech has closed properly, and the unit is trying to find the directory. If the unit then spins the disk for a while then ejects it, then the laser is dirty or faulty. I would suggest getting it cleaned at a shop if the lense appears dirty. ***Never look straight down at the laser lense if it is exposed on your model of CD player, it is a class 3 laser, and you will be doing some harmful home laser surgery to yourself!!!*** Hope this helps! Good Luck! P.S. When following the steps above, if you hear the ticking of the lense moving up and down, but the disk does not spin, gently spin it clockwise with your finger, if it starts to play, or finds the directory, then the spin motor is bad.

NAD C521 discs not spinning


The CD player has a sensor that is supposed to detect when a disc is inserted and spin it up etc. yours might be the problem, either it has some loose connections (that you haven't noticed) or it simply misbehaves. Another thing could be the motor itself that somehow 'misses' the spin up signal and needs a 'manual' boost. The best solution in your case is probably to bring it to some lab.
