Beocenter 9300 cd fault
in The Workbench · Jun 13, 2011 07:57I tried that this morning no improvement. The head is linear, and the guide rail has been recently removed and replaced as part of the renewal of the laser head assembly. The disc now reliably spins for a couple of secon…

Beocenter 9300 cd fault
in The Workbench · Jun 12, 2011 15:10I managed to recap the servo board, which I found easy thanks to the tip on removing the original smd caps (twist them off). Sadly this did not fix the problem and I now suspect the motor (apparently these were prone to …
Beocenter 9300 cd fault
in The Workbench · Jun 8, 2011 15:43Thanks for that. I will use 105 degree and I'm not planning on SMD caps. Incidentally I can't see any pic with your post, would be very interested in seeing the finished result. Do you think I'm on the right track as far…
Beocenter 9300 cd fault
in The Workbench · Jun 8, 2011 08:32I have two more pics which I think show damage on the board which may be relevant, one is what looks like damage next to a cap, and on the other side of the board the TDA7073AT on the right is loosing the print, is this …

Beocenter 9300 CD problems
in General Discussion & Questions · Feb 22, 2008 04:49I have heard from Tim who recommended a B&O dealer, so I contacted the local service centre, they confirmed that it is the overture cd mech, and they will normally replace them in this case. Sadly they do not sell spare …

Beocenter 9300 CD problems
in General Discussion & Questions · Feb 19, 2008 18:16Thanks 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?
Beocenter 9300 CD problems
in General Discussion & Questions · Feb 19, 2008 17:45Sorry 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?
9300 servo PCB
in The Workbench · Feb 19, 2008 17:42I'm trying to solve a problem with a 9300, the CD door opens a second after pressing play without rotating the disc, is this likely to be caused by the servo PCB, and if so is it possible to get some details of the repai…
Beocenter 9300 CD problems
in General Discussion & Questions · Feb 19, 2008 17:37Thank 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.
Beocenter 9300 CD problems
