Maybe it eas beginners luck, but I managed to change the belt, clean and lubricate everything inclusing the motor - and everything works!

Also managed to clean the Beocord and change the belts, so that’s also working again. 

Now I just have to check the DIN-plug for the Beogram, as it has a loose connection - then everything is good as new. Well, almost. Thanks for your detalied description :)

Hi everyone, Søren et al!

Well done, well done!

My own CD50 I did 7 years ago (how time flies!) still works perfectly, and sounds as good as any other player. 

Thank you very much Soren, now i got a working CD 50 for my BM 5000. 

Took some time, but you got here, congratz

8 years after your posting it is still helping out - I have just followed your instructions to change the belt to fix random door and non playing issues. The old belt had stretched and was slipping. I'm now the happy owner of a perfectly working CD 50 again - thank you sir. Oh and to think I was about to sell it on eBay for for parts. 

Nice to see that an old thread is still helping out. With all the music found on line people tend to get lazy and forget about CDs, tapes and vinyl, I must admit that I also got lazy and didnt use my CD50 for about a year now, still playing my vinyl though. Thanks for posting Jeff and good luck with the CD50

It is nice to make the effort to listen to older formats, I have also got a beocord 5000 working again (another belt change) and I was surprised how well tapes sound on this unit. Enjoy 😊 

Thank you for the very helpful step by step guide, I’ve just successfully followed your guide to repair an old unit to fully working order.
