When you get no disk error, that is usually because of a problem with the optical laser lens that is dirty, faulty or opaque, and will start operating on certain disks better than others.

In that case you will hear disk spinning, whirring and clicking, but the TOC (table of content track at start of CD/DVD will not be read, therefore the error.

Whe this problem is starting you may be able to read only CD, DVD or Blue ray, or for example only DVD-R and not +R , or only to read and not to write and so on. After more prolonged usage , often the unit goes losing the rest of functions, and ends up not reading anything at all.

If instead there is no noise, and disk does not spin at all , then there is a faulty motor, or the motor micro-switch is bad. This situation is far less common than the lens problem.

Try first using a CD/DVD or Blue ray lens cleaner disk to clean the lens. If that does not work you will need to disassemble the drive , and clean lens directly with q tips and isopropyl alcohol, or to replace the CD/DVD lens, or the whole drive unit.

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?

I have nad c541i,for last few days,it not reading the cd,as the disc goes in,there's a bit sound from the spindle which goes off after 5 secs,but doesn't read the disc,the screen keeps flashing like --...


this has the sony mechanism so if you take the lid off and unscrew the 2 screws, 1 at either end of the cd clamp and remove it, you should see part of a large cog just under the front of the cd tray, try turn this clockwise and the tray should open.
once open, you should be able to see a small plastic cover, loosen this slightly and replace the belt as this is prone to slipping on this mechanism stopping it clamping the disc properly when closed.
the sound you say is the spindle motor, is actually the loading motor trying to lift the whole laser mechanism up towards the puck to clamp the disc as there is not enough tension left in the belt.
help it along by hand and you'll see what i mean.

hope this helps?

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!

My NAD cd/dvd T550 displays NO DISC.


I have the same problem. When I insert a disk, my NAD T 550 DVD player displays 'No Disc'. It started with new disks while still reading older disks, but at some time it stopped recognizing any disk. Did you receive any suggestion yet or has anyone a suggestion?

No disc


I've dealt with this type issue quite a bit.
Believe it or not the drawer belt needs to be changed.
If the drawer isnt drawn all the way into the unit...the disc motor wont spin and ....you get rejected

Also, if it reads poorly, the lens on the laser could be dirty.

Take it to a tech . Try a local stereo store . They should know who's best. It's a quick easy job for a tech who knows what he's doing.

Happy new Years,

Scott

Won´t read any Disc


I have the same problem since the early beginning after purchase. I'm very upset with NAD for the zero-value technical service in Italy. After 2 months they gave me back my C541 with new defects (the tray now doesn't work properly). They have tried - they said - different optics without fixing the problem. Does anybody know if a compatible optic / tray exists?
Thank you

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.
