I replaced a 2N2166 transistor on Driver board. I hated removing all 18 connectors because I feared there my be a connection problem when I remount the CPU and driver board. Well there was. Game went into a lock up mode. It shows (2500 4) in player one display, (04) in the credits and (00) in the ball in play.
I removed all 18 connectors, and the CPU/Driver board one more time. I reflowed all the headers around the outside and all the center pins that separates the CPU and Driver. Still is in lock up mode. How do I get this out of the service mode?
