Some very helpful info!
Here's something to try. It appears that column 1 is being permanently energised but we now know the driver board works fine so row 7 may be causing this. I would check the Bottom Jet (17) where the column and row intersect. Remove the globe, check the diode and wiring is correct at that point.
Even better if you can disconnect the 2 x row wires from the bottom jet and temp connect them together to completely remove it from the circuit.
