One player score display is burned out or partly dark.

Score display digits dead or dim

Cause: The display glass has worn out.

Checks

• Swap display modules between player positions to confirm the fault follows the module.

Fix

• Fit a working replacement module.
• Or have a new display glass soldered onto the old board (a delicate job).
• As a stopgap on a four-player game, move the fourth player display into the dead position.

Touch the cabinet ground before handling boards or chips; static can destroy solid-state parts. Display supplies on solid-state games run at high voltage; switch off before unplugging modules.
