Question about NAD C521 CD Player

Laser unit NAD 5100 Monitor Series

Hello, My NAD 5100 Monitor Series CD player just broke down. The laser unit has gone. Anyone out there who can tell me if these units are still available, and if so, where and at what price? Until now I was very happy with the qualities of this excellent CD player, bright but never sharp, very good definition. In combination with my Quad 44/405-II worth every penny (and more). thanks in advance, Maarten

Hi Skipping problem with a NAD C545BEE, plays OK for 1 minute, then skips randomly wthin the track, then will skip to different tracks on the CD, like fast forwarding. No problems with the disc themselves


hi
There is a diode in the power supply which gives dc supply to the laser focusing coil driver ic . if the diode get faulty this problem can occur. Just replace all the rectifier diodes in the power supply stage. Its better than searching for the exact one. then check the cd player is it skips the tracks. if then also its skips the tracks then you have to change the laser pickup unit.
ok

NAD CD PLAYER NOT RECOGNISING DISCS


Try this:
1) Disconnect the powercord from the plug!!
2) Remove the cover
3) Reconnect the powercord, turn on the power and press eject.
4) Turn of the power - beware, there is still power on the trafo!!
5) Now you have to carefully clean the laser (round glas-like item in the middle of the drawer) with a cotton swab filled with isopropyl alkohol.
6) Then wait at least 1 minute.
7) Turn the power on again and try to play a cd. If it works as it should then you have succesfully repaired your cd-player :-) Otherwise you may try again.
8) Now disconnect the powercord and replace the cover.

If this doesn't help I'm affraid you have to turn it in to your local shop for further invistigation and repair...

Good luck :-)

My Sony cd player spins but won't play. Cleaned


Those CD cleaners rarely work. They are nothing but small brushes on a plastic CD. Unless the problem is loose dust, they won't work. Try carefully opening up the unit and cleaning the lens using a cotton swab and alcohol. If that does not resolve the problem, post the model number and I'll provide the replacement optics part number and cost. Some units have replacement optics that cost less than $15. Dan

Remote doesn't work in spite of new batteries


If it works well.....$95-150
It's VERY similar to the 512 and 521.
If you can find a remote for one of those it would probably work for yours

NAD 5100 monitor wont eject


Hi ntravers9

You could fix this yourself, in saying this of course, you will need to also source a new belt for the player ( I can help you there too) That is probably what is preventing the Cd tray from opening. If you where to remove the lid, and give the transport a little assistance in the direction that things initially start moving, then you can be sure that the mechanism is not damaged in any way, and that a lazy belt is the source of you problem.

Do this if you are into fixing it yourself, to see for sure what is happening and we can go from there.

Not Recognising a CD


NAD CD platters tend to go dry on the guides, stopping the bottom CD clamp from fully engaging. Disconnect the signal and power leads and undo the four screws connecting the transport to the bottom of the case. Remove and get some very fine grease and smear it lightly on all the runners and guides. Also look at the crank which causes the bottom clamp to move up and down, turn the flywheel by hand and watch it move, see where the plastic lug moves to cause the bottom clamp to move. Grease that too. Wipe any spare grease off so only the minimum is used. Do not use oil. Dean Beedell

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.
