Why might a digital TV keep switching region?

Question

In our house we have a digital TV purchased well before the switchover, which has already happened now. Whilst our location is borderline West / Wales / Midlands (and with the analogue signal, the TV could pick up all three regional versions of BBC and ITV), the appropriate region is West, because of the closeness to, and communication links with, Bristol. The auto installation of the TV originally selected the West options (Channel 1 - BBC1 West, Channel 2 - BBC2 West, Channel 3 - ITV1 West and so on). However, every so often the TV suddenly switches to Wales options, with the West versions switched to a high value channel number. Another thing that happens occasionally is that there is no TV, just a "database empty" error message on the screen. Applying the auto installation resolves this, of course, but sometimes it sets up the Wales versions in Channels 1, 2 etc. I can manually resolve this, but it is becoming irritating. Is this related to the type of aerial, or its position, or is it just changing atmospheric conditions which will always cause this no matter what?

Your aerial may be picking up the digital signal weakly because in some areas the best aerial is different on digital than for analogue . there are several main types of aerial A,B ,CD , and wideband. ( that is low frequency , mid frequency or high frequency)
if the west signal is weak then your receiver will lock on to Wales when atmospheric conditions make that the stronger signal. There are online sites that can tell you exactly which aerial you need in your area.Or a TV shop should tell you .  As the other poster said moving the direction of your aerial may work too. Some digiboxes are better than others . If you  manually  delete the undesired channels  the box will not retune itself during the atmospheric conditions.
