I've been using these settins:
I've tried with LNB Power On and Off
22kHz Tone Use > None
LO Freq 11300
I've had a look for the dish but I can't see it. I have freeview built into the tv which works perfectly. I'm using the same aerial connection as freeview, assuming if freeview is working then Sky should work (freeview doesn't work on the other aerial connection).
If anyone has any ideas or could at least cut down on the number of different setting combinations I have to try, it would be awesome.
