Errors galore after watching for the first time in a while

I can’t say when these problems started since it’s been a long time since I’ve used my directv (work busy, streaming shows elsewhere), but the parents came for a visit & there were issues.

First I encountered a 771 error code (signal loss). But it’s only for some channels (primarily local channels, espn, 249 is broke but 249-1 is fine). Both boxes are affected (so unlikely a cable issue like the troubleshooting website suggests).

We did have some rainstorms lately but nothing too bad. I don’t see anything getting in the way of the dish. Plus I would think if the dish was blocked it would be an all or nothing issue.

Then, as my folks were watching the news on a channel that did work, there was a clicking sound followed by the screen going black & the audio cutting out for a couple of seconds then resuming. The screen will say “an error has been detected & resolved.” (Since I haven’t had this issue with my other TV set, I’m thinking this might be a separate issue with my Panasonic plasma tv. )

Just to try I pressed the reset button on my box & it went through startup & all the checks. But still has issues with the same few channels.

When I went to the 771 troubleshoot website it said to call if there was an obstruction but I don’t see one.

Has anyone encountered a similar issue? Trying to figure out if I need to take a day off work to babysit a repair guy or not. Thx!
