Just got 771 on all the recievers, no weather or obstructions. Ran the test came back 41-xxx on all three. Service call can't get here till Sunday. LNB, alignment or other? Dtv did the install of the new dish with swm in 2009. I think it would be odd for an lnb fail. Is there a different error code for lnb fail? Just want to know how much of my Sunday just got blown.
