I just purchased a Flight 2000 and love it. Having trouble with the ball launcher up in 1st stage chute. Ball gets dropped into chute from collection area at left and it tends to just sit there for a minute and then "wakes up" to launch it over to the 2nd stage chute. This is not a problem when I first boot up the machine. Best I can figure is the CPU is telling it to activate at boot up, but during play the microswitch hair trigger is not working reliably. My assumption is that the contacts on the microswitch need cleaned. Am I right? If so, this seems like a bear to get to. I am still a little nervous about lifting the play field for maintenance. Any advice about safest way to lift and stabilize the play field for maintenance?? PS - How do you clear the High Score to Date?
