My Hd channels kept going back and forth to sd and now I only have my local chanels. Evevn in the guide it only shows SD. Like the foodnetwork, lifetime channels. I just have a couple of channel still shows HD like 187 Hallmark channel.
I have a hopper 3 with sling and two joeys. I did a status check everything is good except I think it is D or E singnial strenght 110 and 129 has a green check mark but the conn. has a red X.
We have had alot of wind and cloudness but when that happend the signial would switch to SD and than I could change back to HD now eveything ecept my local channels
Check for any trees that might be partially blocking the signal. I had a similar problem with mine a few weeks ago. I trimmed a few branches back that I didn't think were in the way but the problem cleared up right after that.
