Just had the problem out of the blue of buzzing and not connecting when pushing the button . Took the base off and noticed th contact breaker for the lower orange arm in particular  here was buzzing and sparking but not holding together. Nothing obvious so guess it's just showing its age. Is there aquick fix? Or at least, a diagnosis from you experts please? I've another b&o deck so it's not the end of the world, but would be nice to fix it I can? Login to view image
