I have a Sony B50 receiver, with all channells, except I can't get HBO,SHOW,MAX or LOCALS, it says seaching for satellite, but when the system got installed, it had a Phillips 5500,which is not compatible with football cards, my question is could it the dish needs to be repositioned in order to receive HBO,SHOW,MAX and LOCALS, or is the dish or lnb not compatible for the receiver????
