I bought an LG tv four weeks ago and connected my Sky Q box as per instructions. Now at that time I could also get Freesat without the Sky box turned on. This weekend I moved the tv to the other end of the room and had to extend the satellite cable. Now I can't get Freesat at all. On the tv screen it just says 'no programs'. I've tried retuning many times but I'm not getting any joy. I had a tv services chap come today and he says I need something on the satellite (lnb?) but I can't understand why Freesat worked but isn't now. Can anyone give me some advice please? I am not really tech minded so please keep it simple!
