I was hooking up a new receiver today and got an LNB Output failure on the system test. I tried re-doing satellite setup and the test failed on 99(b). When I look at signal on that satellite it appears I'm getting signal (high 70s to high 80s) on the first few even transponders and 0 on the odd transponders. I went over to another HR20 which I had installed a couple of months ago without issue and ran the test it also failed on LNB Output. All of the channels I should get...are coming in fine. Signal strength on all of the other satellites are mind 90s and above. I have tried switching cables and checking the connections on my powered multi-switch and all are tight. Dish is a Slimline Multiswitch is Zinwell 616 Zip Code here: 33445 Any thoughts?
