Oxford (Bexley) transmitter seems to be broadcasting the Film4 channel using some kind of weird reduced colour palette (I'd guess 16 colours). I've reproduced the problem on 3 different receivers and had confirmation from someone else some distance away (on the same transmitter).
This started around the afternoon of the 6th and is still persisting as of the morning of the 7th.

It seems Oxford are on Planned Engineering this week so that may have something to do with what you are observing. They are advising "Possible weak signal" which in recent observations from others can mean the disappearance of some channels and other effects for periods of time. If this persists for a lengthy period I'd try giving Channel 4 a call on 020 7396 4444 or 0345 076 0191 as Freeview are unlikely to be much help, they only seem to regurgitate a retuning script which I don't advise when you have weak or no signals.

Thanks for that, I did see: Planned engineering works | Freeview
...so, Central - Oxford - Main - Possible weak signal - is that all the detail that's available? Is an 8-bit colour palette a symptom of a weak signal? The signal reports fine (80%+) and there are no drop-outs, just the washed-out picture for Film4. All the other PSB2 channels look fine.
There seems to be so little information nowadays that I'm feeling more and more of a dinosaur even knowing what Freeview is.

I'm afraid trying to get more detailed information on Planned Engineering seems to be a waste of effort as "Freeview" generally don't seem to have a clue (the best they seem to say is it may affect your reception!).
Whether the DigitalUK staff know what Arqiva are doing in detail (without asking) is anyone's guess, I get the impression they don't, as the last time I pursued a fault with them it was like banging a head against a wall and ended up with Arqiva denying there was any fault - despite the fact that the fault mysteriously got rectified at the crack of dawn on the first day of "Planned Engineering" (ha ha).
As far as the actual problem is concerned, it depends on exactly what they are doing at the transmitter. Whilst a weak signal itself shouldn't cause what you are seeing, whatever they need to do may require the transmitter power to be reduced at some point, I'm not a transmitter engineer!
Past experienced suggests that contacting the broadcaster about a persisting problem gets quicker action than anything else, as they know exactly who to get on to, to get it sorted.
There never has bee any clear information about any faults for any of the commercial transmissions whether it be Radio or TV, only the BBC have publicly accessible reporting mechanisms for anything affecting their own broadcasts.

When I went to bed last night the channel was still borked, this morning it's back to normal. I guess I'll put it down to the engineering works. I am astonished that such a major Freeview channel can get so broken and yet it goes almost unremarked. Oh well.
Anyway, thank you for your informative responses.

Well that is very strange. I can find no current or recent faults listed either by Freeview or the BBC for the Oxford transmitter and it's not currently listed for Planned Engineering.
I suggest that you check all you coax plugs, connections, flyleads etc, unplug connectors check for corrosion or other problems and reconnect them. Flyleads can be a common problem, try swapping them. See what signal strengths (if any) and quality you are getting for the multiplexes shown in your TV's tuning section, this might indicate potential issues with your aerial or downlead. Also check that your downlead looks undamaged and that your aerial seems intact and pointing in the correct direction.
Problematic connections, water ingress etc. can seem to affect reception of just an individual or several multiplexes.
If that all seems ok, I suggest you carry out a retune as follows - unplug the aerial and carry out a full automatic retune which should clear all previous tuning as no channels will be found. Switch off the set for 10 minutes.
Then plug the aerial back in and switch on and repeat the retune, hopefully all channels will be correctly restored.
Also note that the correct UHF channels for Oxford are C41, C44, C47, C29, C37, C31, C55, C56, C46 in the order PSBs1-3, COMs4-8, Local. Unfortunately the site owner has not had the time to update one of the tables at the top of the page as a result of the 700MHz clearance.

Oxford is now listed for Planned Engineering with "Possible weak signal", so there's obviously been some sort of issue.
