If you determine it is indeed a board fault on the row side.
Just going through the schematic have you considered the U10- U13 row ICs.
Which rows are the problem rows? Is it the same row globe that incorrectly lights no matter which column globe is on test or is it only the associated U10 to U13 IC globes that light as 1 chip handles 2 rows?
I hope that make sense.....
U13 for rows 1 and 2 , U12 for rows 3 and 4 and so on.
