The parts in your photo look intact. But perhaps that's merely a photo you found somewhere? Else - ask at Danish Sound Parts. They are known to be able to help with many, else impossible, parts. Martin

It is my photo, there are two small tabs shown in arrows that are broken. Anyway I sourced that part.

The disc now loads but won't play. I can here a clicking sound as the motor spins. When the tray closes the disc raises but drops again at the end of the travel. Seems to be because of the groove on the cog... Is this correct? Login to view image Should the disc be picked up when it is raised, because to me it looks as if the disc is just sat in the tray? I don't have the CD mechanism screwed down but it lined up with the screw holes and I have tried minor adjustments. Any ideas? Thanks.  

You might be able to find some hints in this guide that also has a lot of pictures and recommandations for capacitor replacements

Thanks that link is very helpful. It seems the cog is correct and the raiser should dip at the end of the travel. So my issue is that the disc is not being picked up by the motor when it is raised, it simply drops back down as it would when ejecting. https://www.youtube.com/shorts/uClkDhQwa8E The disc isn't ever going to clamp.

Sorry I am not able to give you any further input as I have yet to start the repair in my own CD50, but am following with interest.

it seems that this forum's interest for the CD-50 possibly died a little of late - the archived version has lots of historical posts and contributions from many members who no longer seem to here!

Ok I found the issue, lower disc raiser was a little bent, the disc are now being raised correctly. However discs don't seem to be spinning and the laser is making a seeking/scratching sound - exactly like in this video: https://www.youtube.com/watch?v=bclDp8K4oo4 I have two players doing this :) Any ideas? Thanks.

Hello again I am now working on my CD50 and after belt replacement I had some issues with the carrige movement as mentioned in this thread

Yes I saw in the comments to the suggestion that the motor requires cleaning and or lubrication. However the two non-working players that I have both had broken belts, so I am reluctant to believe that 2 players both developed in addition a problem with the motor. Also one player I am repairing for a friend who told me that discs were playing fine before the cd tray stopped ejecting, So unless this two issues are a symptom of one another I am reluctant to start stripping the motor down especially since it appears not not to be a simple job. I should add that with both players it appears to me that the disc is not actually spinning - the motor is moving but it seems it hasn't quite grabbed the disc so maybe I will try the adjustments of the copper nut first and also tiny adjustment of the teeth of the main cam.
