I continue to get a 771 error message on my tv every single day. It is fine when I first turn it on but after a couple of hours it starts to get pixelated and freezes. The screen then goes black and the error message appears. I have done all the troubleshooting steps with the exception of getting on my roof. However, I can see that the only branches in the way are about 20-30 feet taller than the dish. There is nothing directly in front of it. I was told months ago (maybe even a year or longer) that I am still using one of the old receivers. But they still have not upgraded it. It is now interfering with my life since I am stuck at home; I cant watch tv and it wont record any of my shows when it is having one of its "moments". They will not answer the phone. What can I do?? I think I should be given a month credit since I can't even watch it. Just frustrated and venting.
