I am restoring a horribly abused Capcom Airborne. It seems to be in fairly good mechanical condition with only a few exceptions. The one I am working on now is a bank of 8 lights that is out on the back board. I've traced (well, not really, the self test kind of told me) the problem down to the driver board JP9 / JP10.6 . I don't see anything physically wrong here (the harness is not disconnected or anything). I pulled the harness on both JP9 and JP10 and reseated them. No change. So, what do I look at next? I have limited knowledge on working on pinballs but I have all the tools, etc to fix whatever is wrong. I just need pointed in the right direction.
