Openbox S9 and 28.2E

Hi all, I had replaced my old S9 with a new one. Problem is that when I set up the new box and scanned 28.2 E I could not get some channels to register which I used to have, e.g. CNN, Euronews, EWTN, Fox News, Setanta. I think I have tried everything I can imagine on the satellite search menu. Can anyone tell me what I am doing wrong?

Many thanks
