So after trying the box in the other location (where the R20 was still working fine) and the HR20 still couldn't get a satellite signal I called D*. After getting through the very long automated menu, I reached the 1st level of technical support where the technician quickly figured out I had a legitimate problem and he bumped me to level 2 support. Level 2 support insisted that there was nothing wrong with my box and they would need to send a technician out. The first available date? May 24th! I asked the level 2 tech how one box could work fine in a given location, but when you connected those same wires to another box it could not work but there be nothing wrong with the box? She kept on persisting with the line that it wasn't the box. When I got upset about being without service for 11 days she said that after the technician came out I could then call back and they would get me a partial credit for the missed service one receiver for part of the month.
You said you moved your fried HR20 to a location that had a working receiver. What about moving that other working receiver to the location where your HR20 died? If that other receiver works in BOTH locations, you could have some ammo when calling D*'s support as a different receiver works in two locations and the HR20 does not.
