I have brought over a sky digibox,dish and dark blue card with yellow house on, all up and running BUT I can only receive BBC1,Channel 4 and 5, the other BBC's,ITV 1 & 2 all say "no signal received", the picture quality is very good even though the signal strength and signal quality bars are only half way on set up menu. Am i correct in my assupmtion that if the signal strength for 1 channel is good enough it should be OK for all others,? am I on the wrong satellite,?is it the card or digibox?, I cannot get any sky channels as they are all subscription but the picture quality is very good on all channels and I pick up all after 12.00 channels with no problems,I bought the set second hand in UK so wasn't expecting too much of it but Corrie would be nice.
