Has anyone heard of one of these doing this? My ID is intact thank god. I thought that the battery might have died. I was outside at the dish all day today and had the 920 out there - tweaking the dish and learning a few satellite positions. Installed and aligned a linear Ku LNBF for X4, got the Q up to 74. Brought it back in the house and hooked it up, plugged it in, it went though the warmup and just a zero came up on the display. Channel count back at the default. Maps are gone. WTF!!???
