Hi,
this sounds similar to what my DP Pro is showing:
Bonus Multiplier Lights (2x 3x ...) are not counting at all. But they are flashing together with the rest.
BOOM Lanes are shifted by one.
Activate B -> First O is lighting Up.
Activate First O -> T-Rex is lighting up.
Activate Second O -> M Is Lighting up.
This is continuing along the POOL Targets, Right Diamonds up to the BAM!.
It looks like one bit is shifted? But only during playing a game. In the demo mode it seems to work fine.
The error is coming and going and I wasn't able to perform the lamp test as it was always gone until I tried it.
Except for the Bonus Multiplier this is mostly not working at all during a game but works during the lamp test.
All the lights are connected to node board 8 if I am not mistaken.
hisokajp : Did replacing the CN2 and CN3 connectors solve your problem?
