I've just inherited a 9300 with a problem CD player, when press play the CD draw just re-opens, it seems that the disc doesn't even spin. Having searched the site I found one reference to a problem with the servo PCB on these models which is a fairly easy fix. Can anyone shed any light on this?

thanks

I am not electrical genius, but apparently there is a capacitor that fails on the servo PCB. This can often be the problem. If you take it to B&O, they will tell you the laser needs replacing. How good are you electrically? If good, ask on the Workbench - the techies hang out down there!! 😂

If as useless as me, we might suggest someone helpful to fix it! Where do you live?

Try the easy stuff first though - how clean is the lens on the laser? I use a cotton bud moistened with distilled water to wipe mine clean, though there are are proper cleaning fluids for this job (also good for the tape heads.) One advantage of this sort of CD is that the lens is at least easy to get at.

Cheers, Steve

Thank you both, I will try the workbench for details of the capacitor, since I have a fair amount of experience of soldering... I tried cleaning the laser head, but no joy, I am sure that the disc is not rotating.

Sorry Peter, I meant to say, I'm in London, so there should be some chance of finding a repair shop. You seem to know quite a bit about the problem for a non techie, have you experienced this yourself?

Assuming you have a 9300 with a radial laser then the normal culprit is C2815 which should be 33microfarads. Much less than this and you will have problems. The servo pcb is pcb 8 situated underneath the cd mech.

Thanks for that detailed answer, I should be able to track that down, would I be looking at a straight slot for the laser head, or an arc, I have a simple straight slot, I guess that's radial right?

No, that's linear. I don't have details of that servo board. May be the same. See my answer in the Technical section.
