    With power off try reseating the short/wide ribbon cable on both ends that connects at the MPU and at the driver board. Sometimes when you have multiple things out like 3 rows of lamps, you may just be missing a signal coming from the MPU.

    Quoted from monkfe:

    I remove the socket again only to find that pin 13 goes nowhere.

    On the driver board, U10 pin 13 is also tied to U10 pin 1, U11 pin 1 and U11 pin 13.
