I set-up my friend's DirecTV system about four years ago. They get their locals via off-air antenna (not available in HD from DirecTV) and have an HR20-700 DVR. Several times since Christmas, when we had a big storm that they also got hit with, the HR-20 has "lost" the locals, with a constant "searching for off-air signal" message (no signal strength in set-up screen either). The antenna and line are both good. We can hook the exact same coax feed directly to their HD TV and it picks up the channels instantly. It's also working fine on a second HR-20. (We even swapped the cables between receivers with no problems. And hooked the other HR-20 to the main living room set-up and it can get locals using same outlet, cable, etc.) We've tried all the usual tricks, clearing and resetting local channels (multiple times), removing and reinstalling coax cord, resetting receiver (again, multiple times), etc. In the past the locals have always "reappeared" eventually (we don't know why or how) but it's getting annoying--this is maybe the third time it's happened and they've been out for days she told me yesterday. I don't really want to advise her to get a new receiver because 1) I'm not nearly as big a fan of DirecTV as I was back then and don't want to lock her into another two-year contract and 2) I also set them up with external hard drive for this DVR and they'd be highly annoyed to lose all those shows, which would be inevitable with a receiver swap. The sat channels come in fine, it is just the off-air locals that are non-working. I'm not at her house now (they live about an hour away) but I was just after Christmas, when I tried all of the above. At some point they just came back on, but I couldn't tell you what combo caused it and she says she's tried everything I showed/told her again with no luck this time at all. Any thoughts or ideas I haven't tried yet?
