Hi everyone ,
I'm new and a neophyte, I bought a gottlieb spring break to restore, maybe today I think it was a gamble as a first pinball machine, but the forum and the information found on this site give me the spirit to persevere.
When I turn on the pinball machine, nothing happens, dislpay is off, the playfild lights are off, there are only 3 flashing lights, from what I understand only the tilt relay starts and nothing more.
This pinball machine was damaged by vandals, the coin mechanism was unhinged, so I thought the problem was the slam switch, I made the change to the MPU board by creating the bridge to bypass the slam switch, I don't know if I did well?
As soon as the flipper was withdrawn, the spindles jumped, so I replaced them all, changed the capacitor and the diode bridges of the power supply and restore the ground masses.
On the Mpu I have the 5v
But now I don't know how to go further, I can't understand if it's a tilt or cpu or mpu board or eprom problem.
Any suggestions? thank you all .
