• Are they all triggered by the same chip? If you've tried reseating all the board connectors then this would probably be the problem. The chip legs on older pinball machines can become corroded and have intermittent problems with connections. The problem is corrosion in the chip socket. Not so easy to clean. 90% of problems I've had with my machine have been either connector related or connection problems between the chips and their sockets. Hopefully it's not a fried chip but I bet if you look hard enough you can find them for a reasonable price. I can't think of anything else that would affect so many components at once. I have also seen modern replacement boards for 200$ or so that replace all the boards in the backglass area.
  • You may have a blown fuse-check all fuses with a continuity tester because fuses sometimes will blow but appear intact-it happened to me (not quite this same problem but a lack of power to several coils) Check the wiring in the machine for any loose or broken wires. Then, look at the solenoid control board (the manual will tell you which one this is) to see if anything is obviously broken-are any wires or traces seperated or anything look like it has burned out? Beyond this you'd probably need a wiring diagram/schematic of the machine, including the boards, test equipment and possibly expert knowledge of circuit boards, so you may want to call a pinball repair service if you can afford it.
