I have had the Los Angeles OTA channels in my Dish VIP622 receiver for over 2 weeks. Now all the sudden today (Sunday) my Channel 7 and Channel 5 are gone with no signal. Anyone else having this problem? Is it the actual signal coming from Channel 7 or is it something else. Because when I go to the Dish 007-00 channel it works fine so they are getting the signal but not me. I get all the other channels except for these 2.
