Problem solved. A simple channel retune cured the pixellation. Thank you for this website.

Hi Richard. I'm glad you managed to solve the problem, thanks for the feedback. Your main transmitter is indeed Wenvoe, but you may also get signals from a number of other transmitters in your location, Mendip being the strongest, then the Llangeinor relay (PSBs only), and some weak/variable signals from Stockland Hill and Huntshaw Cross in Devon.
If you happened to retune (or your set did it automatically) when you had no or badly pixellated signals, it often clears correct tuning and can tune to other signals. Maybe COM6 was down during the Engineering if this happened.
Generally it's not recommended to retune in those conditions if you were correctly tuned, just wait until signals return. (Same when adverse weather affects reception).
Best thing is to check you are correctly tuned to Wenvoe's UHF channels (as listed at the very top of this page).
