Doesn't mean "AJE & RT should also come in"
Gotta know a lot more than "AJE & RT don't work, but the others do" to trouble shoot it.
Did it work before or is this a fresh install? Did someone else install it?
Describe what you've done so far. Describe the 'history' of the system.
Get into the tune up screen and watch the QUALITY reading on the frequencies listed by SatelliteAV. Position your TV so you can see the screen while at the dish. From the back of the dish, gently push on the dish (up down, left right) one at a time and hold for a few seconds. Does any of these tests increase the QUALITY reading? (don't loosen any nuts or bolts for this) Let us know what the results are.
Post #2 & #5 by SatelliteAV are very informative. (Freqs and channels)
