I sincerely hope it's not a CTC74 or 81. If it's one of those then *good luck*
you're going to need it, not one of the fonder memories in this wonderful
business.
It would help if the original post would include the chassis number. It sounds
more like a newer chassis by the symptom.

Also, if that is a CTC 74 or 81, the drive controls on the kine module are
known to open. Spraying lightly with a contact cleaner will restore the
operation, and pick up the picture considerably.
