Hello, I have a Gottlieb system 1 Charles angels pinball machine. I used to play it all the time but one day it just stopped working. Its been a few years but when I finally took a look at it I cant see any physical damage like leaking battery or burnt traces. It starts up normally with 5 second delay and displays all 0's on the screen. But I do not hear 2 clicks when it starts up it is silent. Any idea what I should check? Thanks in advance.
