Quoted from monte_:So I called stern because my NIB AS Pro that I have had for five days would freeze up during play. Lights out on play field, LCD screen on but frozen and would lock up. I could turn it off and on and it would start back up and usually could play a game. Tech support said to me that it could be the sd card so he was going to ship it out so I am waiting on that. Today I had weird things going on. When I would hit the start button to play a game, a song was picked automatically for me and I couldn't select the song. In addition, sometimes it would fire the ball automatically right away. Once I drained the ball for the next ball the same song was automatically selected and the ball would be fired automatically. In addition, the toy box inside part that goes up and down was going up and down for a whole game without stopping with the toy box open. Anyone have any ideas? CPU?
So my toy box was doing this when I first got along with it not letting me pick the song. I fixed the toy box by turning it off, lifting playfield, and physically rotating the motor that controls the inside part 180 degrees so it was activating the opposite switch upon startup. It fixed my toy box issue along with letting me pick my songs. Disclaimer, I’m a newb and know nothing about pinball maintenance, I was just trying things and this worked for me. Maybe try updating your code as well. Goodluck
