I have been trying to solve a problem with a friends digibox but I can't seem to get a grip on it. They have had a main digibox with 2 extra (mini) digiboxes, all with the Sky World package, working fine for 14 months. 1 of the mini boxes will now only get some channels, for example it will get BBC1 but not BBC2 or ITV but will get Ch4. Sky1 and UK Gold are OK but not UK Gold + 1hr. This continues right through the channels with no discernible pattern. The channels it doesn't get will often display "satellite signal not being received". Both the other boxes in the house work as normal. So far I have: Rebooted several times Changed the Sky card with one of the others in the house Exchanged the digibox with a spare I had and the problem remains unaltered. The signal strength and quality are all indicated as good. So, I am deducing that its not the digibox, Sky card, dish or LNB and I would be grateful for any suggestions where to look next. Thanks in advance.
