hi all i have got hold of a Gottlieb System 80b based pinball , its not starting up . no display no start up sounds etc , all that come on is the play field lights ,
5 v is good and its have the battery removed and put away from the cpu board in the past , im suspicious of a lost voltage ,
all 3 bridge rectifiers have a output , the lamps at the top the light up the game name dont come on , no voltage ,
its a spring break
thanks all
