I've got a system 1 a display problem. It's missing the hundredth digit on player 3. When I swap the displays around, the problem moves with the display so I know it's not a connection issue. Does anyone have a link to a guide on fixing system 1 displays? I've fixed a couple Bally displays in the past and would like to try and fix this Gottlieb display.

My Monte Carlo has been working fine and all of the sudden there are 4 switches that won’t register. The left lock saucer, left ramp made switch, middle left top lane and the right inlane target switch that opens the right gate. Any ideas where to start troubleshooting this?

The 4 switches problem ended up being a broken wire under the playfield on one of the diode boards. Also found and fixed my random reset problem by flowing solder on the daughter board pins.

The only problem I can see now is my “5” insert light is constantly on in attract mode. Would that be a diode issue and where is that diode located?

Is it possible to install a stronger flipper coil in a system 80b? I have a Monte Carlo and the right flipper is weak even after a flipper rebuild. The left orbit/under ramp to upper saucer is nearly impossible to hit, even with the playfield set at 5 degrees. The coils in it are A-24161. Just looking for a little more power.

My left flipper has more than enough power for the 10mil shot. The ball actually flies off the ramp sometimes because it has so much speed.

There's already some cracked plastics so I'm not too worried about that. I'd rather be able to hit that saucer and start multiballs versus worry about possible cracked plastics.

Thank you!
