I got a D12-100 activated. When I hooked it up, it had a guided setup and I set my dish to 5LNB SWM setup. I bought it to my cabin where I have a 3LNB standard dish. The problem is when I hook it up it won't get past the white screen with the DirecTV logo which says 'Searching for signal'. I assume it's because it thinks that it should be using a SWM setup and isn't. How do I force the receiver to go to back to guided setup on startup so that I can select the 3LNB standard dish? I can't press menu or anything. I tried reseting the receiver multiple times and even called DirecTV. No luck. I am sure my buddies here at SatelliteGuys will be able to help. Say I bring it back home where the SWM setup is, what do I have do do in the menu to force it to use 3LNB? I can't select it from the dish type because it doesn't detect that dish type.
