Question about NAD C521 CD Player

NAD C521 discs not spinning

My player was frequently failing to recognise CDs when i loaded them, even failing to recognise when there was no CD in the drawer. After removing the cover I realised this was because the motor doesn't start spinning when the drawer shuts. If I give the machine a physical shock (e.g picking one side up by an inch or so and dropping it) the motor starts. Obviously this is not a long-term solution! There doesn't appear to be any loose connections or any significant dust in the machine. Any suggestions will be gratefully received.

Re: NAD C521 discs not spinning

If the motor needs a manual nudge to get the disc spinning then you have a faulty spindle motor.
i've had various cd players with exactly the same problem and once i replaced the spindle motors, they all worked faultlessly.

hope this helps.

Re: NAD C521 discs not spinning

HI...

I own a few NAD CD players and have repaired several for customers.
Main trouble? ..The belt the works the drawer. It also runs the laser assby lift to meet the CD to read. No lift-No spin.
These units also use 14 volt wire-lead bulbs to backlight the display.
This is also a common failure.

Re: NAD C521 discs not spinning

Hi, i have the same player and had the same fault,when moved "vigorously" i could hear something moving inside. Opening the unit i found a small black plastic peg loose inside. Examining the disc transport i found a microswitch with nothing to do! Further examination brought me to a hole in which to put the aforementioned peg,thus solving my problem!!!
Hope this helps someone

Re: 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.

NAD C521 on / off button light


"POWER ON: Press this Green button to switch on the power to the disc player from Standby mode. The LED will change from Amber to Green, and the EFL display will illuminate."

So besides the L.E.D. the unit has another visual indicator that it's turned ON, the display lights up. Is this worth pursuing a fix?

Nad 502 CD will not recognise and play CD every time


HI.This will occur when the optical assembly becomes unstable. this ((Whole One Piece)), assembly incorporates the spin/load motor, optics housing /arm, tracking device and tracking rail. This is connected to the loading dock assembly. This 'NO Disc' or CD NOT PLAYABLE, code is the result of a failed or burned out lens, or misaligned loading mechanism. It is possible that you have a dirty lens cap. you can try using a cleaning disk in this case to confirm actual lens failure. if the cleaning doesn't restore normal reading capabilities, this will confirm my diagnosis.

You will need to have the optical assembly replaced in this case. once replaced, your unit will be able to read and track once more

NAD C521 CD Player It will not play my CDs. The CD drawer closes normally with CD in place but after a pause, the drawer opens again. There is no 'no disk' warning. The 'no disk' warning does appear...


The tray belt raises the laser to proper focal length at the end of closing the drawer. This demands more grip from the belt. If the belt is sloppy, it will slip at this point, even though the drawer is shut. Took two years of repeatedly cleaning lasers to notice this.

My NAD C251i CD player isn't reading disks - platform stops short


To fix it, you need to replace the spindle motor top bearing. The bearing is worn and the player mistracks as the armature moves about under the changing drive conditions. Makes the player mistrack and skip. Because the disc is spinning fast.

Replacing the bearing should resolves the problem.

Hope this helps and have a great day!
