Digital TVs. Nothing but trouble. Havin to re-tune every other week cos they change the channels. When you re-tune, you cant get half the friggin channels that you had before. Cant even find them when tuning manually, is like they've just been deleted. Picture pixelates and disappears then comes back. The sound goes up for the adverts then goes down for the programmes. Never had this shit with analogue
If your picture is pixelating then your aerial could be the issue. If it's a rooftop aerial have a look and make sure it's aiming in the same direction as everyone else's on your street, they can get moved by strong weather or birds landing on it or even flying into it.
If you use an internal aerial it needs to be aiming in the same direction but looking out of a window rather than aiming at a brick wall. Once the digital signal was turned on full power it became a very strong signal so there's no real excuse for a ropey picture these days.
Tuning your tv with a bad aerial signal is a pointless exercise which won't help matters at all. When you do an Auto Tune it should give you a rough idea of signal strength from 1 to 10, and these days you should really be getting a level of 8 to 10 unless you're in a built up area like flats, etc, which could have a greater chance of added interference.
Also have a flick through the audio settings on your tv and see if there's an option to balance or level your audio at all, which would stop adverts becoming annoyingly loud.
