NAD 502 CD player problem

I recently aquired this CD player 2nd hand, the prev owner exp that the drawer would stick closed, but if a CD was allways left in it was ok & yes sure enough this was the case & apart from this feature it worked perfectly well & was very enjoyable to listen to.
Then the inevitable happened & someone didnt leave a disc in & the drawer stuck!
I took the cover off & released the drawer by pushing the cassette down to allow the drawer to open & then put the 'sleeper' disc back in.
Now it doesn't work at all- doesn't register disk or spin up & displays- no disc.
AAAaaarrghhh!!!! Have I broken it permanently???
Cheers, Geoff.

You can try to release the drawer and get it all the way out. Then turn of the power and carefully push the drawer back inside. Then turn the power on again. This might help!

Does it have a failing drawer belt? My 522 was fixed after that.

Player will not play a loaded CD and No CD message comes up Also CD drawer opens and shuts on it`s own !!!


the tray opening by itself could be a faulty limit switch on the tray mechanism

the switch tells the system if the tray has reached the open or closed position.

if it closes then opens itself then this is the most likely

check that first

could be closing then opening without actually loading due to the switch

you will need to open it up to find the switches

usually at the bottom front were the tray goes in

Pressing the 'open' button on my NAD C542 CD Player no longer opens the disk drawer. Any suggestions to fix this would be appreciated. Regards Michael


G'Day Michael,

Having fixed thousands of CD players in my career, and also being a NAD Authorised service guy from 1989 till recent times, I can comment with some authority to your situation, and correct some of the ill found assumptions given to you already.

This unit uses a KSS213c transport. Very common and used in many machines, also relatively reliable.

2a8af3a.jpg
The drawer load motor is not shown above. Is will be mounted on the black plastic load assembly. The drive belt/motor for it will be under the tray runners.
If you do not hear the motor run, then it WILL NOT be a broken or failing belt. However, this is the most common problem with this style of transport. I would be checking anyway to see, the load motors do free run fairly quiet with no drive belt connected. Wind the tray assembly out by hand by kicking the gears over to open the draw to see the belt/motor

Because you cannot get it to work from the remote, AND you have "open" indicator on the front panel, it WILL NOT be a faulty front panel button(never seen one fail ever!)

I have never replaced a load motor to a Sony transport. Spindle motors can be a problem, but they never stop working altogether.

I would be checking the tray mechanics, a jam caused by something fouling the gears may cause a fail. Tap the front of the draw as you press eject to see if you can encourage it to work.
Sometimes, small nylon drive pinions can split, the excessive gap in the gears caused by the split causing a bind. Check also for blown pico fuses in the servo drive stage. This will cause no drive to the load motor.
If you cannot pin down the source of the problem, the player IS welll worth repair. These machines sound great and would have cost you a few bucks to begin with. If you need help locating an expert NAD authorised repair guy I can help.

Happy to discuss any of this further with you. As previously direct your comment to me by name. Cheers

regards

Motor driving CD drawer seems to have failed. Model CDP-502 Jammed in close position


More than likely, the drive belt is slipping. The drawer is locked when in the full load position. It can be opened by hand with access from the bottom. I will try to get a picture loaded later today to show the procedure.

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.

Believe it or not the drawer belt needs to be changed.

CD drawer stuck, then won't close


1. Most of the player drawer fixed over the chasis for a rigid support
2. try to remove the drawer safely without damagind the chasis and drive mechanism
3. there might be some shaft jam.
4. Look for the thread. how does the player drawer moves in and out
5. there may be some sensors to sense the door close/open. if it is jammed then open/close function cannot be done. why because this problem occurs
6. unwear the mechanism read the mechanism moving technique. see which has got jammed.
7. if you feel too risky then
8.contact service centre... all the best
