Thanks for this @sfc1000 !
Wealth of info there, all in one place.
Good to know that someone else also still fixes CD players.
These links are far too long, have 5 lines of code and have info about your browser , session etc.
All that is needed is:

They look good but they are very expensive.

Sorry about the long links. Must be a melted brain, as it's hotter than down under these days.
Yes, I still fix VRDS machines. I've actually just done two VRDS-10's last week. There are still lot's of good cd-players out there.
Kind regards.

I have 2 VRDS CMK4's that have been melting my brain for the last few weeks. I've cleaned and lubricated everything, replaced the gears but I can't get the spindle to go upward - the CD tray is already fully into the player at that point. Without the tray, the whole cycle works and there is no excessive friction on the mechanism that moves the spindle up- and downwards.
What is the correct starting position when inserting the tray? It surely isn't when the hole in the metal base is between the 1 single tooth on the big black gear?
This is the begin position as it stands now, the gear won't move any further. If I insert the tray now past the 'click' point where it locks in place, the gear will eventually grab it, go fully in but the CD spindle won't move.
I have also tried with the single tooth being located perfectly horizontal, the player will then close, spindle will go up but it won't open anymore....the gear won't grab the tray.

Hi @JanKarsten , have you been reading that post? It explains the process on a CMK3,2 or CMK4 VRDS. I did that with my Krell CMK3,2 and it worked flawlessly. I guess it's not far from the one in T1 Teac machine, as the parts look very much similar. Good luck, if it got out, it can get in.
I did and tried at least 10 times from the picture the user posted - it will close once, spindle will go up and after the next open-close cycle the spindle won't move upwards again or the tray will get stuck somehow.
Both positions 'break' the cycle, tried as shown. I then push the tray in until it clicks in place, then I put 5V on the tray motor from my DC supply.
This is roughly what I'm getting, I can get it to close properly once but it won't open anymore, the tray locks up: https://streamable.com/zzis64 and if I pull on it by hand, it gets loose (not touching any gears on the black cog anymore).
The usual gears are new, nothing is cracked.

It can take a long time to find the exact synchronization, the last two I worked on (a krell and a copland) gave me a hard time.
you need to take the time to observe each piece (including the back of the CD carriage), then you start from the low position of the laser block (CD carriage therefore open) (the black pinion has a hole which should be facing another hole in the metal (the laser block must be as close as possible to the center of the CD).
I know it's painful but once you understand the whole movement, it will (almost) go by itself.

I don't understand this mechanism...but it works now. With the tray closed I fiddled a bit with the 'lever' that's next to the CD spindle and it seems to have fallen into place at some point.
Assembled, put everything back together and not touching it again, oh wait - I have another one waiting 😀

It is a pig to work on. But don't delay starting on the second one, or you risk forgetting all you have learned on the first.
Oh my word...I found the problem with the second one and it was completely something I would NOT expect...apparently someone who worked on it before hasn't fully screwed in the 2 screws at the bottom of the assembly containing the 2 large springs where the whole thing is resting on, causing the right side to sit slightly lower - exactly where the tray sensor was.
This explains why the assembly worked perfectly without the flywheel assembly but not with it - with the extra weight of the flywheel the mechanism sat too low to activate the tray switch and the mechanism didn't know what to do as the sensors weren't getting activated properly.
