make sure your coaxial cable is in "cable input at the back of the b0x, also make sure your scart is pushed in fully in the TV & b0x.
Iv had same problem mine only has 5 or 6 channels and rest are bad or scrambled,it only happened over weekend when my NTL went down for while.
menu > 1570 go to "key emu" turn it on . Set Default key press OK Exit to s*y sports & let it update & you should have your channels back.
Do as the post above says. If your still getting no channels, then you'll have to do a channel scan. http://forums.afterdawn.com/thread_view.cfm/662154 edited by ddo
