Could some one give me an idea on how to fix the problem with my 480. Everything works great on it, the line in,cassette deck plays perfect and all of the radio selections such as sw,sw2,and AM. They ALL play super loud except the FM, which is at about half the volume of all my other music sources on the Fisher. Could it be that it needs to be taken apart and tuner cleaner sprayed into the FM contacts? Its amazing how loud this radio goes,except FM. Thanks.
