For about a week now I haven't been able to catch some of my local channels and a few national channels. On these channels I get the "Searching for signal on Satellite (771)" message. The problem appears to be with the odd transponders on satellite 119 and 103. I get 0% signal for these while the even transponders I get 95 to 100%. On the test channels 9508 103 A odd, 9510 103 B odd and 9513 119 odd i get the same searching for signal message. The other test channels say "correct HD dish setup". I called Directv and they are unable to send a service tech out until 10/6/12. My locals are the channels I watch most often. Wondering if I have an alignment issue or a bad LNB. Hurricane Isaac did past right over me 2 weeks ago but I was recieving these channels right after it passed.
