Ok so we have a party for my daughters high school graduation and the pins are all doing fine. I come down after the party to turn every thing off and medusa has a ball in the shooter lane, sound is going, no feature light on, flippers, pops, kickers all work. Looks like some solenoids are not working such as the eject hole, Olympus targets are not progressing properly. The machine will reboot. On reboot, the Olympus targets don't set properly and the ball kicks out to the sooner lane.

I have not dug in too far yet, fuses appear ok, game plays. Just no feature lights and expanded solenoids ( I'm guessing)

Any thoughts on where to start?

Is the clue in the attract light pattern before lamp failure?

So it appears to be in the power supply in the cabinet. I swaped it with my vector and the machine is now working. When I put the original power supply back in, the high voltage 3/4 amp fuse blew as soon as I turned the switch to on.
