In the event that something goes wrong with a joystick or button on your Killer Queen machine, you'll need to access the control panel.
Behind your coin door, there are two latches on the left and right inside wall (the same wall that the coin door is mounted in.) Pull the latching mechanism down on each side.
Grasp the control panel (the panel that the joysticks and buttons are on) and pull it toward you. Up and out!
Once the control panel is up, you're looking for two screws on the outer edge. These screws hold a protective piece in place that you'll need to flip up to access your joysticks/button mechanisms (especially the Queen hardware.)
Remove the screws!
Once the screws are off, flip the protective wood panel up. **Careful: depending on the angle of the control panel, the protective wood panel might not stay up on its own!**
Congratulations! You now have full access to the control panel and can swap out buttons/joysticks/anything your cabinet needs.
