3.1 Powerball detection
For problems like "Switch 26 error" or the powerball being incorrectly detected, see Twilight Zone Eddy Boards.
3.2 Clock
If you are getting the "Clock is Broken" error message, see Twilight Zone Clock.
3.3 Gumball Machine
The Gumball Machine and Geneva Switch: Balls jammed in gumball machine; switch xx error
3.4 Mini Playfield
Servicing the Twilight Zone Mini Playfield: "Magna-Flip" not working
3.5 Clock and Slot Machine Targets
These targets take fast balls from the flippers. These fast balls lead to airballs, damaging the playfield. The targets also get beaten up and broken. It is a good idea to replace them with reinforced targets from Pinball Resources, our you can make your own reinforced targets with parts from Pinball Life. Also, the aftermarket slot machine scoop from Mantis Amusements has a reinforcing bracket. Finally, you can fabricate a rod that holds the slot machine target in place.
3.6 Mini playfield wiring
The switch wires, opto wires, and light bulb wires on right side of mini playfield can get a lot of ball hits. Keep an eye on them for wear, breaks and shorts. A break can happen inside the wire casing where you can't see the damage. Heat shrink tubing over them can provide a little armour for them.
3.7 Mini playfield connectors
The opto and magnet connectors are the same size. When reconnecting, make sure that you match up the wire colours and not just connector size. If these are mixed up the optos will blow out.
