Taking it apart is not hard - if you know how. The service manual will tell you, it's available for download from the products section for silver and gold members along with tons of other stuff and will take you through the task should the need arise. Martin

Michael, Welcome to Beoworld ! This is a very common thing for these decks after standing unused for some time. Contacts inside oxidate. The correct thing would of course be to take it all apart, clean the contacts and put it back together but I'm sure that less will do in your case.
