A few months ago I had to disconnect my cable from the dish and pull it out of the way when I had some trench work done in my yard. Everything was working fine before that. When I reconnected it after about a week, I had no signal. I swapped cables with my other satellite, and it worked fine, so there doesn't appear to be an issue with the cable. I tried 2 different SW21 switches, in an addition to the original, with no luck. A post in another forum said to run the check switch test with no cable connected to the receiver, let it fail, accept the new results, unplug the receiver and restart it with the cable connected. I tried this with each of the switches and still nothing. I'm working with a round dish, similar to a Dish 500 one, with 2 separate LNBs. I also picked up an old oval Dish 1000.2 dish with a 3 LNB setup. I tried that dish, with the measurements corrected to match what's needed to hit the Bell satellites, found nothing. I put the 3 LNB setup on the round Bell dish and tried that, same result. The only thing I can think of left to try is to get 2 new LNBs. Is there anything I haven't tried? Is the receiver shot? Could both LNBs go bad at the same time? Is it even possible to pick up Bell satellites with a Dish 1000.2 with 3 LNBs? Can a 3 LNB setup be used on a round dish?
