I'm located in Cleveland, OH. We've had a large amount of snow recently, and when I went to watch the National Championship game tonight, I noticed that no local HD channels were working due to the Searching for Signal (771) error. I went to settings and enabled the SD channels in the guide as well, and the SD channels (local) come in. Some other HD channels get the same error, some don't. (ie: ESPN HD is okay, cartoon network HD is not).
I searched and read that people were having problems with the LNBs freezing during bad weather and figured that was what I was dealing with but wanted to get someone else's feedback on the issue. I only have one HD receiver at the moment, so I can't check availability of HD channels on another receiver. I'm almost 100% certain that this may be the issue.
Also, I have good signal strength on all except 18 which is reporting zero. I can't remember offhand, but I don't think its ever been zero before. I looked and 17-24 appear to transmit local channels is that correct?
Thanks for any help anyone is able to give me.
