When the game is switched on, the right (and upper right) flippers are energized and hold up, risking a blown fuse. It happens even after fitting a new flipper board, and not on every power-up.
Right flippers energized at power-up: replace the ribbon cables
Cause: Faulty ribbon cables to the flipper board. A ribbon cable that is damaged or partly off the board can lock one or more flipper coils on.
Checks
- Switch the game off at once if a flipper is held on at power-up.
- In switch test, check the flipper button optos are not reporting closed.
- Reseat and inspect every ribbon cable to the flipper board.
Fix
- Replace the ribbon cables to the flipper board.
