I am bringing a SBM back from the dead; it was one I grabbed locally -- previous owner started fixing it, but decided to stop and let it go.
I pretty much have the game working 100%, however, its only fully working because I swapped in a complete set of Alltek boards. I don't want to leave the Alltek boards in, and would prefer to get the old boards working again.
With the old boards in, the none of the displays were working. When I swapped in the Alltek boards, the displays fully worked, so I figure it is now narrowed down to just being an issue on the board.
I am pretty good with fixing many things on my pinball machines, but I am still very (very) novice when it comes to anything board related. But I really want to improve my experience and skills on the board aspect, so I figured this would be a good opportunity.
Is there a section on the board that I should be replacing a set of common parts for this sort of issue? Can you guys direct me on what to test/change on the board to get the displays running on the old board?
Thanks a bunch,
