Working out a few issues with my recently-purchased The Addams Family - this one is a puzzler though. Some of the time (not every flip) - the left flipper turns on the unlit lamps in row 5* to a not-quite-full dim. Is this an issue with the lamp driver or the flipper? Right flipper does not behave the same way. All of the lamps work as expected otherwise and don't affect play.
I've read some articles about TIP102 transistors being used to ground lamp rows - but not sure if that's a red herring.
Thank you for any advice.
