I have an NSM Performer Grand. The title cards won't move (rotate, whatever) When you press the rocker switch on the front which is supposed to rotate to the next cards you get "Error 90" but nothing moves. Can you help? I'm at my wits' end.

Normally that problem is because a card is jammed.

(The Manual will tell you only that Code 90 means the title display isn't functioning, which of course you already know)

Open up the title card box and start removing the holders until you find one that's askew. Normally, for reasons which I don't understand, you end up taking them all out but sometimes you can just yank a few and it will start working again.

Note however that the logic chip will not reset just because the problem is fixed. You have to shut it down (like a balky computer) and then turn it back on. If the problem is cleared it will reset the code and you're good to go.

Does anyone know where i can buy the title holders? I just bought a performer 2000 and it is missing numbers 41-70. Please help. Thanks
