I have had a search of the forums but can't really find any answers to my problem. Recently I have been getting "No signal being received" quite a lot but not all of the time, and while some channels show no signal others will work OK. I have tried the obvious (and easy) option of powering the digibox off and on but this does not seem to solve the problem. I have checked the signal strength and quality and they are both over 60%. Is there anything else that I can try short of calling out Sky and paying out ££££.
