A friend who already has sky box/TV which works fine has just bought from bricodepot a new digibox for connection to a 2nd TV, he has a dual LNB, the dish still points to Astra as sky is still OK, taken 2 cables from dish/lnb, one to sky box the other to the new digibox/tv but gets nothing on the new set up, uses scart to connect but gets no picture just describes a "rolling screen" effect, he has no computer at present hence my posting but I haven't seen it myself so cann't add anything further, any advice that I can pass on woud be most appreciated,regards
