I switched one of my HD boxes from a standard 3 lnb dish to the new Slimline HD dish. Signal strength shows around 94%, but I get NO CHANNELS!!! Get the good old 771 error on everything. Yes, I have the B Filter thingy between the box and the cable and yes I changed the box setup to look for a 5 lnb dish. Now although I do get a signal, it's only on Sat 101. No 110, 119 or any of the others. And I only get the signal on the odd # transponders on that Sat 101. This dish works OK with other boxes. I reset the receiver and did the thing online that sends a signal to the box to re-validate the channels it should get. Any clues as to what my problem might be? The Slimline dish has 4 possible lines going into it and I'm using the third. Any way the lines going into it are configured wrong somehow? This is very frustrating! Thanks.
