NSM Emerald ICE, Half fixed, need help :)

[henryjames]

SO I picked up an NSM Emerald Ice,
Keypad not working so took that apart and replaced the useless nylon pins that disintegrate with some wire instead, now it functions.
CD player also functions perfectly
BUT

Now getting an 90,91,92 Error, so removed all the titles cards and lubricated the slides.

Now when I turn on the machine I can get the slides to move ONCE and only once, they move really nice and freely so they are certainly not jammed.
After this I just get a 90 error message and cant get them to move even with no title cards in place

I can see from peering into the device that the pin on the 'counter wheel' / cog is not aligned with the opto coupler.
Unsure if this is the issue? If it is I don't know how to move the counter wheel as it wont let me when using the button as it just comes up with a Er90, even though I know the slides can move nicely.

Any help much appreciated! Is there any way to 'clear' the error message!?
