Hi, I’ve just bought a Samsung UE65TU7100KX but can’t get any terrestrial channels. The channel search picks up loads (72 I think) but when you try and select one it says it’s not available ‘so I want to delete it’. I originally thought it was the aerial but have plugged a signal strength meter into the socket and it’s full strength. Any help would be fab, thanks. P.s. tried a factory reset and still nothing. Thanks.
