I checked and cleared the codes. There were no recent codes that I did not expect - CD Error 2 and Sledge Error 39 (this probably from when Testmode 71 finished at position 3 and went into standby.

Some good progress though.

I ran TM 67 a number of times to see if I could match CD Error 2, 3 and 7 to particular behaviour.

By chance I noted that once the CD ran continuously and more quietly, still more noise than I would expect, and it turned out to be playing properly, with good sound on the headphones.

After a few minutes, I tried to play another CD and it started at the third attempt. I left it to play the whole way time. It ran much quieter also.

I also got it to play a CD a third time - this one stopped after about 15 minutes.

If this was not a very complicated B&O system that I do not know well, I'd think that the CD drive mechanism was dirty from being stored somewhere dusty for a long time and that it needed cleaning and lubricating, However I do not know this mechanism or the electronic controls.

Sometimes when I select play, it starts to turn very slowly one way then another, just 1/4 of a turn. Sometimes it spins about normal speed one way then the other very fast and sometimes it does not turn at all.

 

 

 

Make sure that when you change to a different cd you open the glasdoor. It resets the TOC which is stored every time you change from cd. 

Beobuddy, understood. I have only every changed a CD by opening the door. I was running TM 67 in different positions by pushing the button under that CD.

Until I understand why the CD is not spinning properly and is sometimes very noisy, it doesn't seem a good idea to order a laser.

My next step is going to be to read the manual on disassembly and see if I can get enough access to clean the CD drive thoroughly. Any advice needed that is not in the service manual?

One thing is very clear in the manual.

If the laser cannot focus, the CD motor will not start.

That is telling me:

- the faint clicking I can hear (1-5 clicks maybe) is the laser trying to focus

- as the CD spins most times I select CD play, directly or via TM67, the laser is focusing most times.

Is that correct?

If the original Cd Mechanismus is still inside it should be a vam 1205 or vam 1206.

both you can nix cheap.

if it is vam 1205 by a cdm12.4 if it is a vam 1206 by a cdm 12.6.

take out the laser of the new Unit in put it in your cd Unit inside the Beosound 9000.

very cheap lasers arround 25€

don‘t use the hole new cd Mechanismus only the laser for the old installiert one.

and you will See your Beosound 9000 will work fine again!

instead of surching for Hours take a new Laser and it will work.

believe me, The Beosound 9000 is one of the bang Olufsen Produkts I reparieren at least twice a week.

sorry for my english, in german it Would much easier for me to explain.

You can buy cheap

Should I fix the noise that the CD makes when spinning before I buy a laser?

Can you explain the noise?

is it because the cd is touching something Döring Spinnengewebe?

when you lay the Beosound 9000 flat on the table, is the CD Mechanismus Set on the right Position?

two screws from the back.

is the Clamper or CD Mechanismus touching the CDs during the movement from one CDs to another?

During spinning?

I set the arrows on the bottom correctly for testing the unit flat on a table. I really did read the manual before I started work!

The noise sounds like a noisy motor or perhaps coming from the CD top clamp. 

The clamp does not touch the CDs during TM 71 u.s.w.   

(Ich kann Deutsch lesen, ein Bisschen!)

It wouldn’t surprise me if the little T7 screw isn’t screwed back again on the lever on top of cd. Or wrong sitting lever, which comes from beneath. Or even possible wrong sitting suspension coils. 

Still no clue (not mentioned yet) which drive is originally placed. VAM 1205, 1253, CD12.6 or even a newer VAM1250 if the BS9000 has had an official replacement of the laser.
