Help with Lamp Matrix

[eldany]

Hi all! This is my first post here. I just own a pinball and it has a bunch of lights that are not working. Looking in the manual i found that the lamps that are not working are all in the same columns in the matrix.

The pinball is The Who's Tommy Pinball Wizard

Columns not working are:

1 (yel/brown)
4 (yel/blk)
5 (yel/grn)
6 (yel/blu)
7 (yel/vio)

just 2,3 and 8 are working ok.
Where should i start? All fuses are ok.
TIA!!!

well since they all seem to share that yellow wire
my bet is a break somewhere within it
or (gulp) hopefully it ain't the board that lights em up that is dying
do a lamp test thru bookkeeping and see which ones light up
it may be just one row of lights that share that wire and that is the cause of it

Thanks for your reply
I tested the wires and all seem ok. I bet it's a issue in the mainboard
(it looks really bad) and that's out of my skills so i'll just look for professional help
