This is a list of known common problems with this machine...

The Mansion area on the playfield takes a great deal of wear from passing balls (especially if they're damaged balls) - the inserts in the Mansion area have their lettering worn away. Check the links page for some repair solutions.

The Electric Chair sink hole take a bashing - again this is another great example of how damaged balls can wreak havok with a pinball. Examine the amount of playfield wear around the hole.

The main ramp can be cracked - most likely in two places - either at the entrance to the Jackpot Ramp or at the point where the Jackpot Ramp doubles back.
