Sunline 2363 radio issues?

I have a 2000 Sunline Coach TT it has a Voyager radio in upper front sofa cabinet. It quit playing any channels, it lights up station on front, I can hear static on the speakers, volumn seems to work, but it picks up nothing now. Antenna seems to be ok on the roof, wiring on back side in cabinet, nothing looks disconnected, but then i am no radio repair person :h, anyone have any radio tech in their blood, as to what is the issue? Has a CD also, but it dont seem to work now either.
