I'll admit up-front I don't know much about modern-day AV systems. Our 10-year old coach has more technology that I've ever had in one place. With a Winegard DirecTV antenna, an over-the-air antenna, a DirecTV SD D-12 receiver, a Winegard Amplified Video Distribution Switch [AVDS], an RCA RTD300 Home Theater System, a Toshiba HD flat-screen TV, and the original big-tube bedroom TV, there are more pieces than I've been exposed to.
With the over-the-air antenna or campground cable, I'm pretty ok. We can at least get local weather - unless we're someplace where's no cable and no local stations, which has happened.
With everything else, though, it seems to work one time, then not when I try it another time. For example, we used the satellite our last trip, and I left the receiver in the rig instead of bringing it into the house and changing the satellite type for use there. This trip, though, I get a No Video Signal message. I played a DVD before; now I can get some audio (but reduced), but no picture. I have no clue what makes the sound come from the TV one time, from the home theater another.
When I occasionally stand in front of the TV and go through everything, by the time I do finally get something to work I'm so frustrated that I don't remember how I got there!
I know I need to put together some kind of SOP of "if you want this, then do..." I wondered if anyone might have laid the groundwork for this at some point, and I just can't find it when I do a search? Thanks for any suggestions.
