Verify that the red line on the ribbon-cable is on pin1 at CPU-J204 and pin1 at 8DRV-J1.
Does switch-matrix column9 work ? test it in testmenu T.14 and T.15 -mark & home switches.

Quoted from pinballholder:I ran T.14 and it shows two closed switches. I ran T.15 and it shows one open switch and one closed switch.
Quoted from pinballholder:I tested all 8 that were on the Aux Driver board (four are for the flashers and the four for the solenoids that are not working)
No, and that is why I asked to test the switches in T.14 and T.15.
Column 9 is generated at this board and it seems to work.
I circled in next picture all components in GREEN that are working since you have a working column 9.
That is 5Volt, 12Volt, Digital ground, ribbon cable correct, etc.
I circled in BLUE the connection that has not been verified, being Power-GND
so, check PowerdriverBoard J103. Is GND connected here and making continuity all the way to 8DRV-board ?
