Mr Dave Thomas: As per the post above yours from "Transmitter engineering", there is engineering works at Wenvoe.
Digital broadcasts are pretty much "all or nothing", with little in between. In the days of analogue, with engineering works and the transmitter on low power and/or the reserve antenna being used (rather than the main one), you may have got a grainy but visible picture, whereas with digital you have no picture at all.

Mr Dave Thomas:
The other thing to remember is IF you have no signal and were correctly tuned before, do NOT retune as this will often clear your correct tuning.
You then have to retune again when signals are back to normal and as you won't know when that is you may have to try several times.
You'll know if some/all of your tuning was cleared as channel numbers will be missing from your channel list.
