Any luck, or further updates to the repair? I just picked up a Demolition Man, and a flipper coil, and popper coil, plus the ball eject coil were hanging loose by their wires, and not mounted like they are supposed to be. I took a look in the backbox, and the Fliptronics board was missing two tip36c transistors. I have never worked on one of these boards (have done a ton of CPU, and driver boards) and was curious as where to start, and the repair steps used to diagnose problems. I thank you for mentioning Leons test guide as I didn't know about it, and Clays guides don't talk about repairing the fliptronic board.
