    Beocenter 9000 CD issue

    Please give me some ideas of what could be wrong with the CD-drive on a BC9000.

    When putting in a CD and press CD or LOAD the door closes and it spins up for a second. Then it stops and the door opens.

    Any clues? Does the CD-drive needs to be replaced? Is a spare still available?

    I am afraid that new cd drives are no longer available. You could try cleaning the laser lens but  I am pretty sure that the problem will be some dried out capacitors on the cd servo board, in particul;ar C2103.

    There have been a number of threads on the forum and a search will reveal the info you require.

    Regards Graham

    OK, thanks.

    Cleaning didn't do the job so next thing will be handing it in for service.

    It is more than likely that an ordinary B&O service centre will pronounce your 9000 unserviceable. You should try to find someone who is used to repairing vintage B&O who will be familiar with the well publicised fixes for 9000 CD problems.

    Thanks Graham for your replay. I tried to find a service manual for the 9000 but it seems to be missing.

    I have also done some search but I can't find so much information about the 9000 CD-issue. 

    Do you know where I can find more information about the c2103 location on PCB etc?

    Best Regards

    C2103 is on the servo board which is attached to the bottom of the CD mechanism. It is a 33uF electrolytic. There are a couple of other electrolytics on the board and it is worth changing those as well.

    It is difficult to find 33uF nowadays so I use 47 with success.

    The BC9500 service manual is on site and the servo pcb is identical on that model.

    Regards Graham

    Re: Beocenter 9000 CD issue

    I was working on it yesterday and think I found the capacitor It's mounted in line with a resistor and the spec is 16v 33uF and it looked like this one had it's days...

    How important is the brand of the capacitor? The one on the PCB is a Philips. What do you use?

    Should it be a bipolar? Is that of any importance?

    Thanks again for your help!
