first of m8 the person above is correct you need a live feed or its a non starter,but while you sort that out,are you using ntl modem?that feed will do.But in the meantime just check if box is working?take it round to m8,s house
and plug it in and see what you get?you don,t have to do this though if you plug box intp power it should light up 02 on led if its modded?If ya get the 02 then worry bout the feed?when you get feed and box 02,s and you get no pic it could be a fualty tuner on box,not to worry if this happens as some one on here will help ya out.and anolugue will run for a few more years.
