trouble with V tuner

i have a cary DMS600 streamer/DAC
sounds pretty darn good
however starting  several days ago i cannot get the V tuner to play any stations
cary was no help - the reply was  "it is the service not the equipment"

anyone have any suggestion on the problem

i still have cd player, nakamichi cassette deck and a vpi turntable. but when i am busy around the house it is nice to just let a station play and forget it.

thanks for any help
