My Black Belt had problems with some lights locked on, some never coming on, flaky switches etc. I got a new power supply board and a new driver board. All the lights now work, but there are three game issues. The slings don't fire - they do fire in test so they are working. The right inlane causes a slam tilt. Occasionally, a solenoid - a kicker or the left drop targets - will fire over and over.

IPDB does not have a backbox photo - if someone could post one that would be a big help. I think all the connectors are on correctly but could use a reference.

Any help or ideas are welcome.
