The subject invention discloses an improved pinball machine and a method of updating existing pinball machines by replacing existing internal gas tube graphic displays with bright, large LED dot matrix or plasma dot matrix displays. These bright and large displays may be attached to a pinball machine within the backbox, external to the backbox or both. These large graphic displays contain multiple display circuit boards that can be separately removed and replaced devices for cheaper maintenance. This method allows any existing pinball machine to be updated with large, bright displays that can illuminate in a variety of colors with adjustable brightness.
