After years of suffering with my original pace satellite box which i have had since 1997. I have bought an Amstrad model 40F115 box. After installing this I am unable to view Sky through other TV`s via the TV links already in place. I have changed the RF out put to on as it states and still nothing. The terrestrial TV signal works fine through the TV link and it is not the cables as I re installed the old pace box and was able to receive a Sky signal on the other TV`s Any suggestions?????
