Hello all! Hope you had some great New Years celebrations! So to start the new year off right I took out my Beosound 9000 MK1 from being in storage for a long while. It powers up fine however I am experiencing a few problems. When trying to play a CD it clamps the CD then just sits there for a few seconds, then get a sound like the electric motor is trying to spin the CD but nothing happens. Then the unit shuts off and restarts itself. Is the CD motor bad? If so has anyone here replaced one before?

Another separate problem is the volume when playing through Aux or radio. The BS9000 is connected to a pair of Beolab 4000 and I have to crank the volume to the max level to barely hear anything through the speakers. Any ideas on that as well?

Thanks in advance for any help!

Tucker:
Does anyone know of a thread about taking apart the clamper/sledge, or have any personal experience?

There is a rather clever mechanism driven by a small motor,that raises the cd player assembly and  releases the cd clamps.It seems that this motor is not functioning?

The dismantling of the cd clamper is logical but fiddly.You need to remove the glass door first,then dismantle the clamper.It's explained in the service manual on site,but it's not a job for the novice,alas.

If you have a B&O techie nearby,as suggested by the earlier poster,it might be easier to consult them?

I understand that the later mk111 mechanism can be employed,and that these are still available,but the clamper motor is not part of the kit.

Sorry to be a clamper damper,but hope you get it sorted,it's worth it

Regards,

Nick

So I got it all apart today and I do believe I need the lower board that has the clamper motor fixed to it. Does anyone on here happen to have this part or know where I would be able to find one?

I doubt you will find the complete lower board. You should rather try to take out the clamper motor and fix it or replace. It should't be especially designed for B&O but rather for general purposes.

Hey Peter. Since then I have tested the motor with a 9 volt battery and it does spin.... But when putting it back together it still will not release the clamps. Any other ideas? I beginning to be stumped. Sad

The other idea is the root cause is not in the motor but in the clamping mechanism. Don't know how complicated it is but certainly something blocking it. Hope external thing ( piece of plastic, small part of cd disk, piece of dirt), If external a blowing or using vacuum cleaner would help. If internal failure ( gear wheels went out, or sometimes a spring which likes to jump out) try to find out what should happen when motor turns and what not allows to do that.

If you don't have any idea maybe it's possible to take out whole sledge and ask someone skilled in mechanics ( a watchmaker ?).

I never dealt with clamper, maybe someone on this forum did.

If you rotate the big gearwheel at the bottom, then you can check whether the mechanism works.

If the set goes into standby, then it could be that the clampermotor draws to much current.

The clampermotor is controlled and fed by the motorcontrolboard next to the powersupplyboard.

The smaller board in the sledge functions only as passthrough.

I can rotate the gear by hand at it works fine. It's when I put it back together that it will not unclamp the CD on its own. It also does not seem to recognize that it did not unclamp the CD. It tries to spin the CD while it is clamped in place...

Don't want to bother you again. But please imagine that someone sent to you a complete sledge in a good condition. So you will have to take out the existing sledge to be replaced by new one. If so, you could do it now in order to examine it and at least be sure that the problem is in that sledge an not outside ( e.g. in motor control board or clamping "jaws")

hi

I know how hard it can be when you do not have more ideas in stock ot halp.
Try to unplug the clamper motor and place a small bulb instead.
If it lights up then you know that the clamper motor is in a malfunction.
If it does not light up, it will be a fault in the connection or on the motor PCB .
At least I think so.
