Paul: Bear in mind that Alexandra Palace will give you far fewer channels and also broadcasts at much lower power (it was only brought back in to service as a relay to fill gaps in Crystal Palace's coverage). Also, which transmitter is your aerial pointed at?

Further to that said by others, to check which transmitter your TV is tuned to go to the manual tuning page and not the channel number for several of the programmes. Freeview transmitters broadcast several programme on common channels known as a multiplex, so some will be thae same as others but some different. Once you have listed some of the different channels found go to the Digital UK Coverage Checker at Digital UK - Coverage checker and put iin your post code and house number. Then scroll down the list and check which transmitter matches the channels you have found on the TV. DO NOT RETUNE.

Yes, the BBCA multiplex will be on UHF Channel 31, the D3&4 mux on C32, the BBCB mux (HD) on C37. You may need a change of aerial to receive them satisfactorily, it was aerial group C/D and is now group A.

As you have posted on the Alexandra Palace transmitter page, there would be an assumption that normally you might be tuned to it. That said there are no reported problems that I can find for Alexandra Palace.
However, that said, depending exactly where you are within your postcode, higher street numbers are showing not only a slightly better prediction for Alexandra Palace but significantly better predicted reception for Crystal Palace. From your locale, both transmitters are easily within the beamwidth of your aerial.
If you normally receive the full list of available channels, see Channel listings for Industry Professionals | Freeview which also tells you which channels are on which multiplex (group of channels), then you will be picking up Crystal Palace
So you may be tuned to Crystal Palace which is currently listed for Planned Engineering, and was also listed before and just after Christmas with "Possible weak signal", this might account for your problems. Alexandra Palace is a relay of Crystal Palace so might have been affected at some point by the engineering work.
If you retune when you have weak or no signal, often it just clears the correct tuning, you can end up incorrectly tuned to other transmitters with weaker signals etc.
Again, depending on your precise location, predictions show several other transmitters might be received in the "wrong" (weather) conditions. So what does this all mean. You'll need to retune BUT do it manually in the manner I'll explain.
It'll be a good idea to start by checking that your aerial is still pointing in the correct direction and appears undamaged and similarly your downlead. The aerial should be pointing at a bearing of between 167 degrees for Crystal Palace and 173 degrees for Alexandra palace, ie between about 13 degrees and 7 degrees E of due South. If need be, also check all your coax plugs, connections, flyleads etc, unplug connectors check for corrosion or other problems and reconnect them. Flyleads are a common problem, try swapping/changing them. See what signal strengths and quality you are getting for the multiplexes (groups of channels) shown in your TV's tuning section.
Problematic connections, water ingress etc. can seem to affect reception of just AN individual or several multiplexes. Also make sure you don't have any HDMI leads near unscreened/poorly screened flyleads/aerial leads as that can cause interference.
Ok, retune as follows. First unplug the aerial and do a full automatic retune which should clear all existing (and possibly incorrect) tuning.
You now need to try a manual tune (look for Manual Tuning in the TV tuning section) on the following UHF channels listed in the following multiplex order -
BBCA/PSB1, D3&4/PSB2, BBCB HD/PSB3, SDN/COM4, ArqA/COM5, ArqB/COM6, COM7 (HD), Local.
For Crystal Palace - C23, C26, C30, C25, C22, C28, C55, C35
OR for Alexandra Palace - C31, C32, C37 (PSBs only here).
It will depend on your aerial installation which you can get, and if your receiver doesn't have a T2/HD tuner, ignore PSB3 and COM7. You might find that you'll be better tuning to Alexandra Palace for the PSB multiplexes and Crystal Palace for the remainder if Crystal Palace signals appear unreliable. BUT too strong a signal from Alexandra Palace may cause Crystal Palace signals to pixellate, so you might have to try to find a good balance. Sorry if this all sounds complicated.
If you can get PSB3 but not COM7 it may be you have an old Group A aerial. It may not be worth the expense of replacing as COM7 is a temporary multiplex and will close in due course at the latest end of June 2022. If the aerial needs replacing for other reasons then a Group T/Wideband is needed to get all multiplexes BUT your location might mean you'd be better with a Group A aerial to get the other COM multiplexes reliably. An aerial installer with good knowledge of your area would know. Also see what your neighbours get.
The above should enable you to resolve the problem, but bear in mind Crystal Palace is still listed for Planned Engineering at present. If you still have problems, post back with more details about your aerial installation, any splitters etc. and which multiplexes you have problems with.
