Hi all, when the ball rolls over the "R" or "S" roll overs they both light. They also light up both R and S lights on the middle of the play field, they however do not complete "WARS" to spelling out STELLAR WARS. So to get all letters you have to guess is it S or R you need for completion.

Has anyone ever seen this situation before?

Now I lost my GI for some reason. Fuse tests good. Is there anything on any of the boards that also controls GI?

Anyone have any ideas? Now it has both ball 2 and 3 in play along with the above problems.

I fixed the GI

I think the other problems are board related I found a guide to check switch matrix my jumpering the pins in the rows and columns at one point I had all kind of different switch numbers displaying. Not equal to the pins I was jumpering.

Maybe the switch matrix IC ?

If anyone is reading this, I am really stuck on this on.

I de-soldered IC10 Lamp Matrix PIA thinking and added a socket and put a new chip in thinking maybe the chip was making the two lights come on together but that didn't change anything.

What else controls the lamps to the roll over switches?
