Cyberlight Gobo issue?

My cyberlight cx's fixed gobo wheel overlaps onto the other wheels. when it should be in the "open" gobo position it is actully half of one and half of another. I've heard it is a homing issue. Can i fix this myself? If not how much should i expect to pay for the fixing? I live on long island if anybody wants to fix for free:notworthy:
