I have a Hr20-700 that is having pixelation issues on certain channesl, most notable ABC. I get the 771 error periodically. I do not get this on all stations and am trying to figure out what the issue is.
I ran a system test and it says I have dish alignment issues. I have 5 other dvr's in the house that do not have this issue and do not give this error message.
I ran the signal strength on each tuner and each satellite to help narrow down the issues.
I aprpeciate your help with this. Thanks.
