This is a ground fault either coming from an improperly installed receptacle (which is more common than people realize), power plug, broken ground braid, or potential broken wiring inside the cabinet.
There are other causes but these are the most common.
Use the "forearm test" (above your wrist) on all areas of the cabinet. Let the game be energized for a couple of minutes. Every place you feel the "tingle" is related to the fault.
Identify quickly as the problem will not get better, but worse.
