After the game was moved, all controlled (insert) lamps stopped working, while the rest of the game played.
Controlled lamps dead after moving the game: loose ribbon cable blew F4
Cause: A ribbon cable had slipped partly off its header in transport, and fuse F4 on the power board had blown.
Checks
- Pull and check each fuse out of its holder, starting with the lamp fuses.
- Check that every ribbon cable and connector is fully seated, especially the one between CPU and driver boards.
Fix
- Reseat all ribbon cables and connectors, then replace the blown fuse with the correct value.
