[QUOTE="2old4this, post: 4623, member: 174998"] well, it's a long-shot but here's an idea: Both of the channels you mention are vertically polarised. I'm wondering if you do not have a universal LNB. Perhaps you have an older LNB with separate vertical and hortizontal outputs, and either a switch box feeding a single line from your old analogue receiver or esle both LNB outputs going directly to the receiver. In any event, when you use your digital receiver to switch between channels of different polarisation, it automatically sends a special signal up the coax to your LNB's polarisor, to cause it to select the right state. But only universal types recognise that signal. And if you have replaced your old LNB with a new universal type, did you also get rid of the switch box? You should. See if you can receive any of the following FTA vertical signals: - Canal Canarias (12441/v/27500 fec 3/4) - Motors-TV (12610/v/22000 fec 5/6) - CNN-Int (12168/v/27500 fec 3/4) or indeed ANY Vertical signals... 2old [/QUOTE]
