I recently moved my STTNG (not sure if related) and decided to run thru the switch test to remove the Borg switch errors (error dot because I never seem to get the ship loaded).
When I open the coin door, i get the normal door open/power message. However, of the four buttons, only two seem to be working correctly. The left (back/exit) and volume up button (3rd from left) work all the time. The volume down button (2nd from left) doesn't do anything. When I first open the door, sometimes the right/enter button will act like volume down...otherwise it does nothing.
