My QE43Q60R has Terrestrial and Satellite antennas so I can select 'Terrestrial', 'Freesat' or 'Satellite'. On two occasions, now, it has refused to select Terrestrial after watching Satellite. I just get a 'No Signal' message even though it is showing TV as selected. The first time it happened, I decided to power down at the mains supply and re-power and signal returned but it did not work this time. There is definitely an issue here. I can still watch Satellite and the TV Channel numbers and information appear on Freeview but no sound or picture. I can also get some TV Plus channels but those are streamed, of course. This is just one of a list of niggles with this set which I am beginning to regret buying.
Update: I can get some channels but only about 1/4 or 1/3of the total. The rest come back 'No Signal'. I have a Freeview box running from the same aerial socket and that is working fine. Signal Strength is 94%, Quality 100% and BER 0 on the working channels.
Update 2: I ran Device Care but nothing found.
Update 3: Fixed by running Autotune.
