keith batt:
It is never advised to retune when you have no/very weak signals or/pixellated pictures if you were correctly tuned in the first place as this very often just clears your correct tuning.
There has been some quite strong tropospheric ducting/temperature inversion periodically affecting large parts of the UK in recent days. Retuning means you can end up tuned to some distant transmitter whose signals disappear as conditions change. You then have to retune again, which you may have to try several times as you won't know when the signals are normal! Not all multiplexes will be affected, it depends on where the interference is coming from as it can be very frequency dependant.
As you haven't given a full postcode, we can't advise if there are other specific issues that may affect reception in your area. Have you checked that your aerial still looks intact and is pointing correctly?
Have you checked all your coax plugs and connections behind your TV?
Make sure that you don't have any HDMI cables running close to your aerial cables.
Have you ever received a postcard from restoretv.uk ?
Your best bet may be to find which multiplexes you are currently missing, see
Channel listings for Industry Professionals | Freeview for which TV channels are carried on which multiplex and then manually retune the relevant UHF channel for the Oxford transmitter.
Note, if you normally receive the Local multiplex (depends on location) Oxford uses 2 UHF channels C22 & C46 which are beamed in different directions and which you get (if either) will depend on location.

This is a bit of a strange one.
According to all the listings I can find BBC1HD/2HD/3HD/4HD and ITV HD/Channel 4HD/Channel 5HD are all on the same MUX.
Keeping it simple I have two tuners both capable of receiving the HD channels.
Tonight as I write, one is recording Channel 4 HD and the other is recording BBC 1HD/4HD ITV HD and Channel 5HD.
I can't figure out why they are split. Any ideas?
Thanks

Stephen Petitt:
I'm not finding your "explanation" as clear as it could be. I'm not sure what you mean by "split".
Yes they are all on the same BBCB HD (PSB3) mux which is UHF channel C47 at Oxford.
You aren't perhaps also tuned/receiving this mux from another transmitter which could be received in your locale? If so, those TV channels would be on different LCNs, probably 800s, if either tuner has more than one transmitter.
I'm wondering if another possibility might be causing confusion - that's something called CLM (Channel List Management) which is now operative for BBC channels on some of the latest Freeview Play compliant devices. This is where the BBC HD channels are copied to LCNs 1, 2, 9 (BBC4HD), 23 (BBC3HD) and the SD versions moved to 611, 612, 613, 614.
CBeebies & CBBC HD and SD are swapped LCNs to add to the confusion!
Apparently, if your internet connection goes down for a lengthy period, the channels can swap,back (or even end up in the 800s)!
