Usless NAD C 515BEE cd player

[lost in translation]

Hi everyone, I'm new to the forum and in desperate need of help.

The facts:
I bought a NAD C 515BEE cd player in Jan 2008. It's been hardly ever used and never caused any problems. The cd player was put into storage beginning of 2010 for 3 months, which also means is now conveniently out of guarantee. The storage was good - no dump, shaking, dropping etc, well packed and together with amlplifier, tape deck and other electrical items. When the stuff came out a few weeks ago everything worked great apart from the NAD cd player.
To begin with when playing any CDs (official CDs not burnt ones) I got NO-DISC message. After giving up for a couple of days I then tried again. This time to my surprise I got this: 00 --:-- then the first song kicked in and played for few secs then stopped and back to 00 --:--
Since then I now always get this 00 --:-- and then after pressing the PLAY button few times it goes into DISC ERROR mode.

If anybody could shed some light over this I would be VERY grateful.

I'm also not sure will be worth getting it repaired depending on what the prob is. Bear in mind I'm not very technically minded but am very annoyed and fully prepared to open the damn box and put my hands in it if necessary!!

Thanks again to anyone that is going to take the time to read this and answer me !

First step has to be to clean the lens manually... not with a cleaning disc.
Use a good quality cotton bud dampened with warm water... don't use ISO.
Camera lens fluid is probably OK... never tried it though, I still use some old Sony stuff left over from training courses.

You could also check for any grease that may be blocking the sled movement ....condensation is very unlikely, but possible especially if moisture got in to connectors.... but clean the lens first and check for proper mechanical movements...

Another very likely cause of the problem could be that the caddy is not engaging the end-of-travel switch, so spindle motor never starts to spin…

So, open the player, check the switch, see if the spindle motor starts to spin, se if lens tries to “find” the disk…. (and then clean all contact / connectors, clean the lens and check / replace the grease anyway!)

Hi to everyone!

I bought a NAD C 515BEE cd player in 2008 and have similar problems. Since a week I get the NO-DISC message and the motor does not start to spin. I opened the player, cleaned the lens and tried it again: But after loading a disc, the motor doesn´t start spinning - although the lens tries to find the disc - and the NO-DISC message appears again.
I still have to check the end-of-travel switch..... If "lost in translation" solves his quest, I would be grateful to be informed how.
Thank you!

Mooly and Boky huge thanks for coming to the rescue

I have opened the box and cleaned the lens (several times now) as suggested but to no avail.

I tested the player with the box still open and plugged in to the mains: the caddy mechanism seems to work fine but what I have noticed is that when I put the cd in the spindle motor def starts spinning very fast for few secs, but with the message on the display panel still reading 00 --:--. Then there's a small click sound and the CD slowly comes to a stop. If I press play it starts spinning again and then stops and so on.
Any other suggestions greatly appreciated!

PS: Boky I couldn't locate the end-of-travel switch any chance you could tell me what it looks like and where I can find it?

Dredging up this old thread to see if a solution was found. I have a 321Bee that does essentially the same thing, but the CD will spin. It will spin, try to read, click-click-click, then give me a no disc on the display. If I open and close the tray about 30 times it might, might read it. Many times it will spin, give me the number of tracks and total time, but not be able to read the first track.

I've opened it up, cleaned the lens 5-6 times, cleaned off the grease-regreased (sled seems to move fine), etc......

Any suggestions as I figure it would be cost prohibitive to have it fixed?

I have posted before how to check the eye-pattern; there should be a test point on the PCB where the eye-pattern can be tested. If it is < 1.4V pp then the laser output should be increased until it reaches 1.4V pp level. Some CD players require 1.7V pp, some 1.2V pp depending on CD mechanism / servo combination used.

And.... if you are going to reply to this post saying how it is not advisable to increase the laser output level... pls don't, spare me that bu&^%$t.
