Quoted from Supersunny76:
Hi guys.. I've check the fuses on the main board.. all ok..and one under the play field.. that's ok too..(have i missed any?)
Placed the balls at the bottom as next to the kicker.. turned it on.. and the same...
I still have 7 flashes and the voltages are good... any ideas?
What is showing on the displays after the game boots up?
