To revise a pinball machine, the playfield must be thoroughly examined to ensure that every component functions properly. Therefore, the first step is to remove the playfield from the cabinet, which is a necessary process that allows complete access to all parts. Despite taking extra time to remove the playfield, it’s a worthwhile effort in the end. Fully disassembling the playfield helps pinpoint unnoticed underlying problems and gives greater accuracy to fix any issues. Overall, this methodology provides better results because it offers unrestricted access to the different components.
