Re: How to fix a Cambridge Audio Azur 640C

Nope...found the note in the box. Removed solder bridge. All is working. Took 18 minutes from start to finish once I removed the solder bridge.

Just saw your note about the solder short...it was 8 months ago after all.

Re: How to fix a Cambridge Audio Azur 640C

Hi,

I also have Azur 640C (version 1) for the past 4 years.

Lately, it is having problems in reading the disks.

perhaps time for lens replacement.

But i don't have the exact screw driver to open the CD player. So I am unable to read the exact Sony Lens number (KSS). The KSS213 series has many products starting from B,C, D to Q.

Could any owner of version 1 please tell me the exact number of sony lens (KSS) so that I could find out the exact replacement.

thanks in advance

Re: How to fix a Cambridge Audio Azur 640C

cbs,
My 640C is version 1. The screw driver to open the unit was purchased at Radio Shack, it has a small star shaped head. Should be able to pick one up at most electronics stores or on the web.

Mine required a KSS-213c. I ordered from B&D Enterprises.

Re: How to fix a Cambridge Audio Azur 640C

Remove hood from unit. Open tray drawer. Unplug...drawer stays open and out of the way.

To remove the pickup unscrew the brass screws at 1 & 2. The assembly has 2 pins that were held in place by the brass screws. On the other end of the assembly is a small post which fits under the black gear (partly shown in next picture at the bottom).

Notice the white plastic rail the laser rides on. There is a small piece of plastic below the lens assembly that fits on the underside of the plastic rail. You can see it on the third picture, directly above the number 8.

Slide plastic stop at 3 back to allow rod to slide part way. Remove plastic gear at 4 (best to remove it from the backside, see 8).


Close up of plastic clip at 3 which stops the metal bar. Move it aside to allow bar to slide partway.



Remove flat wire from old pickup and turn assembly over. Should be enough slack in the wires.

Remove screw, washer and spring from 5 & 6. Slide bar out at 7. Push plastic gear out at 8 to remove the old pickup.



9. Remove solder short on PC board on the new laser pickup. Forgot to do that initially, caused some concern for awhile when nothing worked. Use a soldering iron and solder sucker. They use a solder short as electrostatic protection.



10. Here are the part numbers (KSS-213C) and the flat wire connection. Fairly easy to snap in place. Reverse all of the previous steps to put it back together, test it, if it passes put the hood back on.

Total time...18 minutes. This should be similar to the process for a broken DVD player.

Re: How to fix a Cambridge Audio Azur 640C

Thanks so so much Ron for your tutorials with photos.

Now it is very clear to me on how to go about it.

No need for spending money and time seeking a technician as you have potentially made me one.

Once again, a big thank you.

Re: How to fix a Cambridge Audio Azur 640C

Dear Forum,

I know that I'm reviving an old thread, but I read the thread with great interest. I have a Azur 640C and I was experiencing a "grinding" noise last night after pushing the standby button (no CD in tray). I did not insert a CD until this evening and I received the "no disc" message. I opened the top and checked the gearing and everything appeared ok. I also ordered a new pickup, just in case.

Would you have any other ideas as to the grinding noise. Now when I place a CD into the tray and push play, the carriage closes and the CD spins twice then stops and displays the error message. I sometimes get a message that says "no play".

I really like the way this unit is put together and I'm comfortable with working on it. I appreciate any ideas as to what I can do to fix the unit.

Best regards,

Don

Sounds very much like the problem I had. The new laser pickup fixed it.

Not sure. Mine spun a couple of times and gave me a No Disc message.

Re: How to fix a Cambridge Audio Azur 640C

Hi Ron,

I have been looking for a place to help me change laser pick-up for my Sony MHC-555 which uses 213DH. Finally I landed here and got 213C from the local repair shop (that was the only available in 213 series). System worked perfectly fine after putting new laser but after a while things were back to where I started.

Problem with my system is it read disks intermittently. To elaborate further, as per my observation when you load disk to the tray it first rotates disk slowly and you can hear laser softly hitting the disk. The moment laser is able to read the disk, probably first track, the disk spins real fast and you hear a burst of laser hits to the disk. And finally disk stops spinning unless you press "Play" button.

Now in my case disk starts spinning with initial slow speed and laser hitting disk softly. But beyond that behavior is intermittent even after changing laser. At times it reads the disk and disk starts spinning real fast with loud laser burst heard, but fails on other instances on same disk and just keep spinning the disk at slow speed with soft laser hits unless you power cycle the system. I even burned new disk at 8x to ensure it is not the disk which is causing this behavior but to no avail.

Can you please suggest me a solution to this problem as I have already changes laser pick-up. Other components that one can suspect are disk motor and one switch that senses inner end of disk (it is a small switch with a long level where laser assembly hits as in old DMP printers to sense home position).

Thanks
Sanjay Jain
