Here I am again!
Earlier this year I bought a full Beosystem 6500 in white. The Beocord needed new belts which I replaced myself, but the Beomaster had more complex issues, so I have had that repaired by John at Merlin. I’ve just got it back and it’s fully working (thanks John!).
I had only tested the Beogram turntable briefly before, but now that I have the Beomaster back from repair, I set up the whole system and I think for the first time played a whole album (or side 1, anyway). It played fine, but then when it finished playing, I heard an unpleasant clicking noise, and when I lifted the lid, the arm was raised but stuck in position above the record – it appears to have tried to return to the right, but had only moved a centimetre or so, and stuck there.
With some difficulty I remove the record and removed the platter and wheel. When I removed the wheel and belt that sit below the platter, the motor was spinning constantly as though stuck in play mode. I have disconnected it from the mains, but if I reconnect, that motor starts spinning.
On the inside, I notice that the raise/lower cog is in the wrong place and I cannot turn it manually more than a few mm either way. The main cogs that drive the arm however are completely stuck – no movement at all. If you try to move the arm left or right, it is also completely stuck in place. Obviously, I don’t want to force anything for fear of causing damage. I’ve managed to fix a Beogram 9500 before (the wire drive had come loose) but I’m stuck here.
I have attached photos of what I see inside, in the hope that one of the experts here might recognise the problem.

Minor update – I have managed to get the raise/lower cog (part 1636 in the service manual) back to it’s correct position. The start/stop cog (part 1604) is still stuck firstly in position and will not move at all.
I am unable to unscrew and lift the top panel to get a better look inside as the arm is stuck in a position that doesn’t give clearance for that. I suppose I could disconnect the wire drive from the sliding chassis in order to move the arm and then lift the lid, but I’m reluctant to do that, especially since I am really not sure if it will help.
I have looked inside my Beogram 9500 for comparison and the raise/lower cog 1636 is now in the same position as the 9500. In the 9500 the arm can easily be moved by pushing it, and the start/stop cog 1604 can be moved easily (if reluctantly!), but on the 6500, both of those the arm and the start/stop 1605 cog are stuck very firmly and will not move at all.

Today I plucked up the courage to disconnect the wire drive that moves the tonearm. With that disconnected the tonearm moves smoothly, but it made no difference to the start/stop cog (part 1604) – still completely stuck in position. I can see nothing broken so I’m sure it’s something out of place in the mechanism, but I’m buggered if I can find it.

I realise it’s not easy to triage remotely, so thanks yery much for trying.
Yes, exactly as you have said. Cam Wheel Z (1604) is frozen in place. So is Swingring Y. As a result of those being frozen Wire Pulley A is also frozen, even if I remove the wire.
If I do remove the wire from Wire Pulley A, the tonearm moves smoothly, so the only thing that I can gather so far is that the tonearm is not the cause of the problem.

Yes I’m sure you’re right. I don’t think I’m confident enough to do that myself. I’ll take another look at it tonight but it seems likely I’ll need to get a professional to look at it.
I know Multicare will be able to fix it, but I was just hoping to avoid a long drive to Leeds!
