For the last several weeks, we've had problems with some HD channels, we get complete signal loss, or partial signal loss, or tuning to SD equivalent messages. I have talked to Dish, and they had me run checks in the system, but said that they'd need to send a tech out, for $95. At that time, the system diagnostics showed all three sats, 110, 119 and 129. Now, I went into the menu, and 'point dish' and 129 doesn't come up after it got to 100% (green boxes for the other two, and a red box with an x for 129). I did a check switch and got a message that I'd lose channels if I saved it from there, so I didn't. I've been reading old threads about this issue, and trying to narrow down the problem, but it seems to be getting worse, since we seem to have lost a satellite. Is this a misalignment issue? We've had Dish for a long time, and we haven't had any problems like this before. I suppose the dish may have wiggled out of alignment somehow? Any other ideas? Thanks in advance!
