Servicing the Twilight Zone Mini Playfield: "Magna-Flip" not working

The 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.

Wires on right side of mini playfield

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. And can break inside casing where you can't see the damage. Heat shrink tubing over them can help. LTG :)
