Hi Everyone - I have been a Directv subscriber for almost 20 years. I live in Canada so of course cannot call Directv or should i say AT&T for support on an odd 771 error. I am only getting the 771 signal loss on satellite In 2, on channel 239 (audience network). All other 250 channels are fine, and when I check the other receivers in my house, all the same thing just on 239. I have checked my cables, I have checked the B band adapters, my signal strength is sitting at 99%, my slimline dish is aligned correctly, I cannot for the life of me figure this out. Does anyone have any thoughts on this? Has anyone seen this before? I know I have not seen this before and I am now stumped on what to do. I would appreciate any assistance with this. Thanks in advance!
