Quoted from CaptainNeo:I know it's not the diodes on the sockets, because I just put in all new sockets and all new diodes and triple checked them, because I had to go back, and pull all the LED's out, to put bulbs in. Just to make sure the LEd's were not screwing with the system. So while I had them out, I made sure every diode was on correctly, and on the right contact points. So all sockets are checked and triple checked. So now I'm moving to the boards and connectors. All my connectors look like new. even when I pull the pins out of the molex, they are shiny and new looking. Also redid the pins to make sure we didn't have cold solder joints.
Sounds like it's time to bust out the logic probe.. Does the board have standard PIAs ? Weird that the whole matrix would fail in a similar way, unless they just went cheap and used 3 bulbs per drive and hoped no one would notice or care. Maybe take a vid of you stepping thru the test and showing each bank of 3 lamps lighting could help one of the electonic whizzes here offer better suggestions.
