Following Matador’s advice, I tested the still “functional” drive with several discs.
There is no logic in the results, as some CDs with a lot of tracks work fine and some don’t.
On a few of them, the discs is read for a few seconds then stops.
In one case on a short disc, the sound was highly distorted.
I suspect that tuning of the CDM2 laser is not adapted to the CDM4 servo board.

To Matador: I did not test a lot of CDs as I was unsure that the mix between lasers and servo boards was safe.
To all: I went further on the CD150 alternative solution and found that the grey 14 pins connector of the Beocenter’s drive is split in two separate connectors (9 + 4 pins) on the Philips one.
The last option is to send my drives to someone who is able to repair them.

To Martin: Sorry but I could not localize the smell.
I always carefully removed the ribbon cables using the ZIF connector on the servo board.
I agree with you, there are sharp angles on the CDM 4 and I hope that the seller took care when he recapped the unit.
To all: Today, I exchanged the laser units from one drive to another, here are my findings:
CDM 4 servo with CDM 2 Laser: plays well on an 8 tracks CD except a noise when moving to a track at the end of the CD, but does not work on a 18 tracks one. This behaviour was identical on original CDM 2 unit before the “smell incident”. See these videos:
CDM 2 servo with CDM 4 Laser: same symptom as on full CDM 2 unit after the “smell incident”. See this video:
I come to the conclusion that something is wrong on both servo boards as no perfect result is obtained.
When it comes to lasers, I suppose they are still functional, but I suspect the CDM 2 one needs some tuning and I have neither knowledge and equipment to proceed. I have no idea for CDM 4.
So “I send an SOS to the world” and would be grateful if somedy with the know-how could take over this repair. Of course, I take all the costs.
Thanks by advance and kind regards,

What to do?

Thank you Martin.
The set was VERY dirty when it arrived with a lot of dust inside that I removed with a paining brush and the aluminium lids also need a deep cleaning.
What product can I use to do this?
Yann.July 22, 2022 at 5:19 pm in reply to: New feature: B&O Radio can now be used by ASE products #6921
Same for me.
Recieved today my Beolink 5000 updated by Pilatomic.
Great job, everything works fine!
The remote control has now a Beo4 look with the screen always on.
Wrong post, sorry.

Thanks Peter and Chartz for your informations.
As I am not particularly skilled with my hands, I’m not very confident in swapping the idlers.
Chartz, I understand what you mean, but I don’t see how to identify which idler is the loudest and how / where to put it.
I think it’s more sensible to digitize my tapes first and will update this thread once done.

That’s it, my BL 8000 are now finished:
After an extensive cleaning following Matador’s tutorial:
-New damping material placed,
-Foam tape exchanged with Beobuddy’s supply,
-Bushings of the main transformers exchanged by new ones supplied by Beoparts (part number RP-008 proposed for BL Penta, 3000, 4500, 5000).
They shine like new!!!
My warmest thanks to all contributors of this brilliant thread,

You were right… again 🙂
3 rubber buffers were broken in two parts, the 4th was the only still in one piece.
3 drops of loctite made the job, I feel more secure now.
While the set was opened, I took videos of the moving parts at the 3 speeds. The belt on the right side moves strangely. The set is more noisy when “closed”.
Videos are online on this playlist, if you can’t reach them just tell me: https://youtube.com/playlist?list=PL5Sdc5VmHaOJJCaNR6syj5EfxE5SZrQ_H
PS: The type stated on the schematic is 4136 50 Hz

Chartz and Omminp, thanks for your precious informations.
I opened the set and cleaned what I could, including the heads which seem to be OK.
I did not put oil on the idlers, as I don’t know which kind of oil to use.
The exchange of capacitors is unfortunately out of my competence.
The connection from Beocenter to the Radio input on the BC 2000 works.
I kept a connection from the Line socket to an USB soundcard and tested the recording on a laptop. Test was successful.
Good surprise, a small envelope containing the schematic is stuck inside of the bottom plastic case.
2 problems remain:
1: I cannot find how the chassis is held on the wooden frame. I found one screw on the right side, underneath the headphone jack but could not find anything on the left side.
So if I place the set vertically, the chassis tends to get out.
Unfortunately the service manual available on the old site is in German and I don’t speak this language.
2: The set is rather silent on low speed, more noisy on middle speed and supersonic on high speed.
It does not work when placed vertically.
Could a video help someone to diagnose where the defect stands?
Thanks for your help,
Nobody to help me?

I tested the set and bought it.
By chance, the heads are not worn out, so I can play the tapes.
But Chartz was right, idler wheels must be hard and the BeOcord sounds as a BOeing 🙂
As my project is to digitalize the tapes it is not so annoying.
By chance, the line-out works but the plug is wired in a strange way, as input and output pins seem to be reversed.
So to connect it to my Beocenter 9000, I have to fiddle with Din/RCA/Din adapters.
Tomorrow I’ll check the speaker outputs.
A bit off-topic, excuse me but I don’t know who to contact.
In the old site, the service manual of LC1 just shows 1 page.
I have the feeling that the file is not complete.
Is it possible to check?
Yann.July 3, 2022 at 5:33 pm in reply to: Help for BeoCenter 9000 tape. Update: it’s not the belt #6464
Thanks for the info, my mistake is corrected.
Do you have any clue for the remaining problems?
Does the reading of the tork-meter tape video shows something useful?

I exchanged the belt with a one bought to Dillen a few years ago but never used.
Unfortunately with no complete result : fluctuations while reading are gone but the other defects stay unchanged.

And did the videos give you other clues?July 2, 2022 at 4:08 pm in reply to: Help for BeoCenter 9000 tape. Update: it’s not the belt #6436
I just had a look and these parts are for Beocord 9000 and I have a Beocenter 9000
Are you site they are adapted to my set?

What do you mean by tyres?
