Two buildings 20 yards apart. Two radios with docking stations work fine in bldg. A, neither one works in bldg. B. Both buildings have outdoor antenna with same view of the sky. LCD display shows station, artist and song title but no audio. Radio in bldg. B worked for about 5 years then quit. Replaced antenna and wiring in bldg. B still not working.
Turns out the problem is with the power unit. It is a switching adapter that powers the speakers along with the radio function. Not sure exactly how it works but it can power the unit without powering the speakers. I have a new one on order, will update when it is received.
