I recently acquired Stars by Stern. When I turn the power on, lights come on. And the game instantly goes into tilt. I can run the self test button on the mpu and get the machine to flash the lights and also to fire thru the solenoids.
I disconnected the door slam, plumb Bob, the slant, side cabinet switch, and also the tilt mech under the playfield. Still no luck.
Any suggestions on what else to try?
