My CZ-6a hasn't been ground balancing properly with the "Pushbutton" method . Most times I get to hear the audio tune but other times nothing(at the same spot with no metal around. Also I heard things banging around inside control box. When I carefully opened control box a 3/4" circuit board screw and a small piece of plasic with a tiny screw fell out. I screwed back the 3/4" screw but can't find where the other piece goes. Do I need to send unit back to Fisher in California for service or is there a more local service center? Thanks to all...
