Connecting sat dish to TV

All my LG tv bought in Spain needed was when setting up use a U.K postcode and Freesat works perfectly

I just bought an LG tv today, we have a satellite dish and an Iptv box I have now relegated it to the corner of the room as just can’t get any programmes to load, with saying that when I went back to the home screen E4 was on but nothing else could be found, sorry longwinded recommendation for someone to come and set it up please,

I bought a Phillips tv from Media Markt- the inbuilt tuner works fine with the UK satellites.
