In mid-game the referee calls a goal that never happened, the crowd sound plays, and the flippers and coils go dead.

Flipper Football scores false goals and kills the flippers

Cause: The eight opto pairs in the goal behind the five drop targets have bad solder joints, so the software sees a goal and ends the ball. Seen even on new games.

Checks

• Watch the goal optos in switch test for flicker.

Fix

• Remove the goal opto boards and resolder every emitter and receiver.

Systems

• Capcom

Games

• Flipper Football
