Hi,

I've been doing some search on CD transplant. Many says its a flip-flap operation.

But they also mention a plot to desolder after shipping and lots of measures against static electricity.

Can you tell me more about this two things?

Can ESD precautions be taken easily, like touching metal, wood floor, not moving etc etc?
Is it that easy to burn the mechanism while mounting or is it all this exaggerated?
I mean, I've just teared appart the whole BS9000 twice without thinking about precautions and it still "work". Is the CD more sensitive?

Finally, any other thing I will have to face or must know before going on?

Sorry for the truck of questions and thank you in advance. 

Ok, I'm in Switzerland near Geneva BTW (check my last message) :) 

Cd lense are sensitive but you can go as long as you are aware you should touch something made of metal before and you don't wear a polar jacket or something like this during the process.

Good luck !

Just buy a CDM12.4 laser on ebay, and swap the laser only. It is easy, and it will work after that(if the laser you find works). No soldering blobs or anti-staic stuff to take into account.

If you look at the laser ribbon(after you have dismantled the cd mechanism, it will say "3067 EF-20". This is the CD12.4 laser. If it does not say that, then you should find a laser with the same markings.

Use antistatic gloves with all you do on electronic inside.

On the VAM12.4 there is no need to desolder anything at least from my experiance.

If you want to place ribbon correct, take of alu plate and set ribbon plus bottom of BS9000.

Pleace all ground wires back in plece.

Thank you Nanan,

Yes, in the meantime, the sellers gave me the part and I manage to refit it, But thanks again for your help.
By the way if you have other spare parts I"m looking for the spring for the left hinge (the one without cogs).

Thats perfectly what I wanted to hear 😁.

Now I need to wait exchanges with China to be "quieter" to order a new mechanism.

I let you all know…

Thank you Weebyx and Marexy,

Will check the laser ref and order accordingly.

Hi everyone,

I'm happy to announce the BeoSound 9000 is working again. Disc spinning playing, resting as originally oriented.
Appart from some random ratling noises which I recognize as coming from the flex cable (and therefore will remains as it!) and as far as I've tested it, it works.

I must say that replacing the laser was quite a thriller: you have to push some parts to make them pop very close to other parts or thin wires which seems to be fragile. Maybe when you know what you do it's easy but when it's the first time, believe me, I'm still trying to reduce my heartbeat while writing :-)
Looking back, I've found easier to fit back the sledge motor and the wires. That said, it's not an impossible task either.

Anyway, It's working and I'm happy. Pictures will follow 😕 

And here is the beauty !

That is a very nice system...   Glad you were tenacious enough to get it working...   This sort of project always scares me!!!

Great Job
