Definitely a reading problem.
I would check/clean/lubricate the tracking mech. as the first thing.

Don't suspect the laser. They very rarely fail.
And don't fiddle with anyadjustments - it will only add to the problems.

Thank you Martin, I will take a look soon at the mechanism.

Parts are ordered  also :)

Well, I took the CD-50 apart. Cleaned the mech but that wasn't too bad. The mechanism of the lens 

also functions smooth. Belt is not perished.

Don't really understand what the issue is but I made another video of this:

Am I wrong or is the Beomaster only compatible with a certain type of B&O speaker? I see that it has no common speaker

connectors like other audio brands have.

No one?

Quite contrary.

All Beomasters built for use with passive speakers use standard DIN connectors for the speakers.
The 2-pin DIN connector is the only industrial standard connector for home stereo speakers.
It's everything else that is non-standard.

Beomaster 5000 will work with all passive speakers and, indeed, all B&Os passive speakers have DIN plugs/sockets.

For use in Beolink/Speakerlink systems, the speaker connectors have an additional pin or two for control and communication.

Martin

Are the ones you're referring to the connectors with one round and one flat pin?

I've read now that the Beosystem 5000 was mostly fitted with the Beovox S55, but others will do just as well I think as long as the specs add up.

Or just other brand speakers with that 2-pin connector attached and with the right specs (impedance etc.)

BTW, on the CD-50, do you have any suggestions on what the fault could be? I had made a video on it, here you can see what the motor does.

It spins back and forth until it stops and rejects the disc.

Spade and pin, yes.
You can use any passive speakers, regardless of brand, as long as the specs are within reason.
If you decide to stay with the passive Beovox range I'd say the bigger the better.
Anything from Beovox S55 upwards, really.

CD50: Either a spindle motor problem or a tracking problem.
I cannot say which from here.
The lasers practically never fail.

The motor seem to spin freely enough I think, but not sure how smooth it should be able to turn though.

It didn't run since I have the unit and the motor was gummed up a bit so I took the clamping mech off the shaft and cleaned that part up. It runs much smoother than it did.

Did notice however that from start, when the disc is entering, the it never spins once.

So maybe that is an indicator that the disc does not rise far enough into the clamping mech in order to be read by the laser and that is what's causing the motor to spin back and forth? Wild guess......
