After a high score the game will not let the player enter initials, and the lane-change feature (which moves the lit extra ball lane) does not respond.
Can't enter high score initials: cabinet lane-change flipper switches stuck closed
Cause: The extra leaf switches on the flipper buttons that tell the CPU a button is pressed were both stuck closed, so the game never saw a fresh press.
Checks
- In switch test, look for the left and right flipper (lane change) switches showing closed with the buttons released.
- Inspect the second switch stack at each flipper button, not the one that fires the flipper.
Fix
- Regap the lane-change switches so they open when the button is released.
