I just picked up my new mini lite 1907 yesterday. They took me through everything to show everything worked and what not. The stereo worked fine when I was there and when we got the camper home. Shortly after I had the stereo on the sound went out. Power was still on just no sound. I'm thinking the speakers were blown or there's a loose connection. I tried defaulting the system but no good.
Ours in a 2104s did the same thing. It was due to moisture and general weather conditions. Once it warmed up and dried out some, they started working again. We had pushed every button we could think of trying to get sound.
How 'bout them Cowboys!
