I've posted photos of the old board, not sure what cracked solder joints look like (or if the naked eye can even see them), so please let me know!

Also thanks again to everyone who's pitched in and gave their suggestions and ideas on what the problem may have been, now l'm back to enjoying my new pinball machine! I'm already eyeballing another one; there's a guy here locally selling a Congo machine in fantastic condition.

Thanks again buds!

Glad you got it working. 
I don't see any pics, where did you post them.  Most of the time you can see the crack joints but not always.  I had some flaky bulbs on my GREED lights on my Addams Family.  I checked the diodes with a DMM and they were normal.  I could see a cracked joint on one of my pins and reflowed the solder to all of the pins and it now works perfectly.  It may not have been the solder joints though and could have been the optos.  It's always hard to tell if youur not there looking at the machine and the parts.  Have fun with the game.
