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.
