We live in Dolybont and receive our signal from the Dolybont Freeview transmitter. This morning we lost all signals except those on PSB1 BBCA, namely non-HD BBC1, BBC2 BBC Four, etc. Retuning found a signal at only that one frequency, it did not find the other two channels (PSB2 D3+4, PSB3 BBCB0 we have been using to receive HD broadcasts etc.

I think you have a fault at the Dolybont transmitter that started today, 14/02/2019.
