Slack: I'm very sorry, I saw your last summer reply just now! too much work, naturally... If the counter does not work, you have to first check the supplies (+5V and +12V) to the Counter PCB 1.167.765 (the large vertically arranged board at the left of the capstan motor when looking at the rear of the machine) are correct.

Also, check that the connections between the Counter PCB and the Display PCB itself are good. It might be as simple as that ;-) If all of this is fine, then maybe IC11 on the Counter PCB might be toasted (it's the driver IC for the characters on the Display).
