Quoted from hodgesm0:Hi guys, I’m trying to figure out a part number for playfield lighting board circled in the attached photo. I think there is a short in mine that is causing lighting issues on my machine. I know it will probably be unobtainium, but also interested if anyone has or knows the whereabouts of a replacement.

so...I'm gonna second the thought that you should not be writing off the board just yet. In my experience, its almost never the board and the couple times there was a problem, it was easily fixed. the lamp boards are basically just the 10 or 15 lamp sockets on one board to make it easier to change bulbs. In fact, many of the system 11 boards were just that, actual lamp sockets soldered to a pcb. The 3 things to look for on the board would be 1. diode 2. cold solder or solder bridge on header 3. bad lamp socket, either the bulb or tabs. There's nothing else to break.
