FT - sounds like a switch matrix problem. The VUK firing may suggest the switch is closed on the VUK (thinks there is a ball present). Check all the trough switches. On power up - does the display mention there is a ball missing ?

HS2 - Is the game level ? you may need to check the action with the apron off - Did it just "start" to do this ?

Thanks for the advice mate.

FT - Will check all switches. Yes, I'm getting a 'pinball missing' message, and you cannot start a game.

HS2 - Game is level. Yes, it has developed this problem all of a sudden. Will have to investigate further.

Thanks again.
