I have a customer who is having a strange issue with a 722. It only recognized the sat corresponding to the LNB output on a 1000.2( i.e. port 1 only 119 or port 2 only the 110, ect..). They also have a 322 that works just fine. I swapped the LNB, still happening. Ran a test cable, still happening. Reset the it twice (unplug and holding the power button), same thing. Then I tried a unactivated 722 just to see if the check switch worked, and it did. Reconnected the cable to the first 722 and the signals now come in for all three. Anyone know what is happening?? The customer receiver has the latest software, and the unactivated receiver software version is 2 versions ago.
