DVR 622 local channel scan issues

[markcosenza]

I have a DVR 622 and I've had a problem with the detect local channel scan function for quite some time. While I receive all of my local channels from previous scans when I first got the unit, the scan itself doesn't seem to work any more and doesn't detect any channels. I didn't really care before, but I now have to rescan in order to get one of my local channels back and I can't do it because it claims not to detect any channels. I've also tested by deleting a few local channels that I receive and seeing if the scan picked them up, but it did not.

I have no other issues with the receiver broadcasting previously scanned over the air channels, but it seems that the scan function no longer works. (I have a very strong signal on most of the channels I get now - between 85 - 100% for all of them...) The one I"m missing used to show 100% strength as well.

Any ideas out there?

Are you re-booting after the scan?

Not typically, but I have done so before. When I first had the issue, I've reset the unit and tried again and no change in status.
