So I recently picked up a Gottlieb Diamond Lady from someone who couldn't get it working. I did all the ground mods and board mods, put in a new power board, cleaned connectors and nothing....no display...no solenoids kicking on....nothing. What's odd is that when the power to the display is plugged in, I'm less likely to get a blinking light on the one board. Anyone got ideas? I'm willing to try anything before I go ahead and order new boards.
