To start with, I am a complete DIYer I own my own stuff, installed it, upgraded it, and have been a customer for about 15 years. I also put in a couple of relatives systems. I moved a 1000.2 dish the other day for one of my relatives, due to a project at their home where it would be in the way. My previous mount was plumb and level, and I had good signal, with 129 being the weakest, but only lose it if there is a severe and dense storm. So there was no issue prior to the move, equipment has worked for at least 5 years. Two receivers connected. After moving the dish and a little realignment, I have a little better than before levels on 110 and 119, but nothing on 129. I ran a Check Switch from both receivers and it shows and X rather than OK for the 129 position. 110 and 119 show ok. Needless to say...most of the HD's are not there. I took my identical LNB off, and swapped it to their dish (trouble shoot with a known good part) thinking I would find a bad LNB. Well much to my surprise, it did the same thing. I rebooted both receivers twice (hard reset and unplugged) and the check switch runs, shows same with my good LNB. Nothing else changed with the setup, just the location of the dish. Brought my LNB back home, it works fine. From what I know...the Check Switch looks at the LNBs not the signal...so even if it is misaligned, 129 would show OK as the electronics are there, correct? Appreciative of any feedback I can get...I was going to order a new LNB, but looks like thats not the issue. Both receivers work fine otherwise. Any ideas? And thank you in advance.
