A small issue began to appear in my X-Files machine recently and I wanted to share its cause since it’s something that can easily be over looked and maybe is not something the occurs often. One of the playfield insert lamps was becoming intermittent. At the base of the playfield, where the ball drains, there are a set of 7 inserts which light up and animate during play. One of these would occasionally not light up as part of the sequence. Then it became more frequent, until eventually it stopped lighting up at all. Given I had changed all the bulbs to LEDs as part of my rebuild not too long ago, I figured it wasn’t as simple as a blown globe and a quick swap over to solve.
