I recommend an anti-static cleaner for videogame windows and CRTs, pinball glass and the glass windows in cranes where the fur can really fly on the freezing cold winter days to come. Speaking of winter days, pesky problems with static electricity are often better neutralized at the source rather than trying various combinations of grounding, ungrounding and rubber mats. When static becomes a problem, simply spray the carpeting in the area immediately in front of the game. Lightly spray a radius of five feet or so. Here is a repair trick that's worth its weight in gold.
Many games fail when they get hot.
The game will work fine when it is first turned on in the morning, but after warming up, the logic board fails. With the game turned on, use the hair dryer on the hottest setting to heat the integrated circuits on the board. Practical experience has shown that heat related logic board failures are caused by the memory devices. Don't be afraid to get them good and hot. You cannot damage an IC with the heat of a normal hair dryer.
