Hi Rex, I got my 9500 CD player fixed by Tim Jarman at Beocentral. He didn't need to replace the CD drive, though they are available and I got one quite easily for £90. Best to contact him at Beocentral for advice - http://beocentral.com/

Good luck, Tony

Hello, can you please give me some advice. I have an 9500 which I cannot part with. The CD failed recently. When you try to play a disc, unit makes a clicking sound and the door opens. When the laser failed there was a very strong electrical smell. I took it to B&O repairs and they said the circuit boards had already been re-done, and it was the spindle motor that has failed. They tested it with a battery. Do you have any idea where to source one of these? I have a CDX CD player. Is it the same spindle motor in this unit as the 9500? (I was thinking of taking it out and using it for parts). Any suggestions would be much appreciated. There are no other service centers in Melbourne to get a second opinion!! The guy at the shop has repaired many of these units with CD failure (I was told). It would be a shame to not be able to get it up and running, as out of allmy B & O kit, including the new stuff, it is still my favourite piece of toy!! Thanks so much. Regards Rex.

Sorry to come in as "tail end Charlie"on this topic,but if the disc motor can be heard running fast before rejecting play,it may be a power supply problem rather than servo.An easy fix if you can do "fiddly" soldering ?

Always a good investment to replace the caps on the servo board,particularly if they are the little blue jobs.The black type seem to last quite well.

There were two types of cd transport used on the '9500.The earlier one used a "bombproof" induction type motor,and the later one was direct dc drive.The later mech seems to have been more troublesome.The various mech's and servo boards are not interchangeable.

Just my "two pennuth".

This is a new possibility! I'll add it to my list of things to investigate. I'm not at all technical and wouldn't attempt to fix the unit myself, so I'll need to find a repairer (NOT the B&O centre) to look into the caps, power supply etc. At least I now know that the unit can be repaired without replacing the whole innards. As I mentioned previously, I'm now away until mid January, and won't be getting the Beocenter back from Exeter until then. If anybody can recommend a repairer, in the South West or London areas, I'd be grateful

Tony

You must be exceedingly unlucky to have 2 CD units with blown lasers! I have always found that it is the capacitor has been at fault.

Are you familiar with the school of thought that says that only the original make and type of 33 microfarad capacitor will work 100% in this application.

There are numerous post on this subject in the Workbench area of the forum.

Yees, but, cause I haven't found those blue1's, I tried several different types, no go. I don't belive it's laser issue here, something else.

I had a blown laser in my BC8000 as well. The trouble in that case was that somebody had been there already before me, replacing some other caps (and forgetting to solder a couple of them!!!) and doing god knows what...

Yes, not planning Anything like that, just curious...

I have cd5500 wiht same fault as AJStokoes BC9500. I have changed cap to this also, didn't help. Unit has been lying on the self now for some time, because I don't have working scope. This uses also same radialswing laser unit.

I have heard that CDM2 and CDM4 laser units were interchangeable but I have never had the need to do it as of the 30 or so units that have needed CD repair from me, it has always been the C2103 capacitor that has been the culprit.

I believe that several European members as well as Auric in the US have reported success with swopping laser units from Philips branded CD players or indeed have purchased new laser units from Philips spares suppliers.

I think that the point that Chris was making is that it is not possible to lift the complete CD mechanism from a BC9500 and plant it in a BC9000 and certainly not cost effective even if it were possible.

Hi Cris

Just curious, what mechanism is used in 9500?

I just repaired, Beocenter 9000 CD. Changing caps did not help, so I found used CDM4/19 transport, and put it's laser unit to 9000's CDM2/10. And it works beautifully.

Of course must check adjustments to make it perfect.

ps. these transports are found for ex. older Philips players.

I'm on a steep learning curve here, I'll need to get my 9500 back from the B&O workshop (which won't happen till after Christmas now as I'm about to go away for a few weeks), and have a good look at it, you guys have given me several options now - clean the head - replace the capacitors - replace the CD transport. I'll start with the easy option!

Be aware though that the BC9000 uses a completely different CD unit to your 9500 so don't go looking to use the same unit as mentioned by Orava. I'm still pretty sure that it is a capacitor problem though as the CD unit in the 9500 is pretty robust.

Chris.

PS Mika - love that screw.....

Yes. And it is not a fake, but a genuine printout from the online spare parts ordering system, pricing for installations that are not an accredited Sony service. I have no first hand part with this event, but apparently Sony in Finland didn't quite like it being published, hence the censored fields...
