How to fix a Cambridge Audio Azur 640C (or any other CD player)

Two weeks ago I got the dreaded "no disc" message when inserting either a burned disc or a Redbook CD. No warranty, only have $300 in the thing. What to do?

Tear it apart and see if it can be fixed! Better yet...find a website that will walk me through the ordeal! Here is the website.

Looks like I still gotta tear it apart.

Here it is with the hood off. Picture 1.

Two screws to remove to get to the lens. Could have easily moved the lens by turning the plastic gear. What is the fun in that? Picture 2.

The lens assembly. Used a Q-tip to make sure it moved freely, brushed all the dust off of it (really didn't see any).
Picture 3.

Close up of the lens. Note that it is manufactured by Sony. Used some magic cleaner (Isopropyl alcohol would have worked I bet) I picked up at Lonestar Audio Fest yesterday, sprayed a Q-tip and wiped the lens down. Reassembled....it works .
Picture 4.

Tried a lens cleaning CD; complete waste of time. Looks like you have got to get right on the lens to clean it. Did not see any dirt or grime on the lens. Used a magnifying glass. Must be real sensitive.

The magic cleaner. Thanks to MaxxHorn speakers .

That's great info! I have 740C and will remember that. These players are very proprietary and I would hesitate to attempt any repairs beyond a lens cleaning, etc.

Re: How to fix a Cambridge Audio Azur 640C

Oops...got the dreaded no disc message again. Could the lens be dirty? Took the cover off, cleaned and cleaned the lens with no results. Looked closely at the wiring and made sure each connection was tight. Pushed connection, tested. Finally started working when I pushed the connection in the red circle. The ribbon cable is the only one from the transport mechanism, only tested two other connections on the transport before I tried the other end of this cable. Sprayed it with DeoxIT, put it back together and it is playing in the background as I type.

Re: How to fix a Cambridge Audio Azur 640C

Likely the pickup is going bad. Look on the side of the pickup assy and get the number. This looks like one of the cheap Sony pickups that you can get a replacement for easily. Just remember to remove the solder bridge before installing the new one.

Looking for me, just google my username. I have used the same one for most sites for many years.

Re: How to fix a Cambridge Audio Azur 640C

Well, given my experience with that vendor and the reputation that they have among servicers, I don't think I would use that source for such a part. There are numerous vendors that have them, however. Just match the KSS number on the white tag and look to the parts suppliers listed here:

Also, you might refer to the information in Sam Goldwasser's FAQ referenced in this list:

lcaillo,
Thanks for the heads up. I hope never to have to replace the pickup. Fingers crossed.

Looks like the pickup has finally given up the ghost. New one on order.

Re: How to fix a Cambridge Audio Azur 640C

Got the new part, simple to replace...but...it don't work. Correct part number, checked all connections, no luck. Put the old laser pickup in...works fine. Still suspect the laser assembly is going bad, hope I can get a replacement.

Did you remove the solder bridge like I said above?
