Hey Guys,
I picked up my first ever pinball machine, a HUO RBION and I love it. I don't know very much about pinball machines yet but I want to learn. I've had it for a few weeks and it was working 100% but tonight the ripleys scoop quit registering. When I hit it in it has to go in ball search to get the ball back. What's my steps in solving this? Do I need to run a diagnostic first? Sorry for the noobness!
