This is my first machine and I am very new to repairs. I’ve watched two really helpful videos on YouTube on system 1 machines and am since stuck. The game will turn on and run (sometimes) but it seems as if there’s a burned out transistor on the driver board. The bottom three displays don’t work and the kick-out hole starts in the up position when the game is turned on (and returned to the down position when turned off) I was wondering if anyone can help. I’m thinking about replacing the driver board entirely but I don’t know if that’s a wise decision. Any help would be appreciated.

Yeah! I’ve gone through a lot of this and it’s helped. I think I need to dig deeper into it though

I was thinking about repinning all of my
Connectors before doing anything else
