If so, there is one last resort. Put your analog on G1, if the servo wires are still hook to analog, then put the analog on an ODD channel. Turn on 905 and and put it on G1 channel 100
Then press options 6 7 7 8 this will put you into a hidden menu and select factory reset. Do not attemp to power it up or change channels, wait for it to warm up and download. Give it at least half an hour for the maps to be reloaded into receiver from the G1 bird. G0 is no longer used for downloads. You do have a susbscription yes? This will only happen if you have a green light, if no green light then change analog receiver to an even channel. Hope this works for you.
P.S. did you lose power in the house just before all of this happened
Good Luck,
Dave
