The pedal under test controls mode randomly switches on and off like it's over sensitive. Because of this it will start a game on it's own. Not sure what to "fix". I'm guessing a dirty potentiometer.
I've had this same issue before - if you are lucky and the pot doesn't need replaced you may just need to go into the setup menu to the controls section and re-calibrate the limits of the pots. (This is different from the calibration test screen at bootup)
