Odd display issue - Bally Nitro Ground Shaker

[PinballDaze]

Bought this in for my comp in full working order but.... not quite.
In display test, only get odd numbers, so 1 1 3 3 5 5 7 7 9 9.
Have replaced u10 and u11 on mpu to no avail.
Have alot of other niggles to sort through so asking for help yo save time etc.
Thanks,Dave

Have a check on connector J1 pin 25 (bit 0 of the BCD segment data)
If this is permanently high I think it'll give exactly the symptom you describe.

Thank you.
I will check this section out.

Thanks backbox. This is the problematic area. Cleaned and it's now even numbers! Made me laugh. I'll replace the connector.
