The symbol shows the location of the Oxford (Oxfordshire, England) transmitter which serves 410,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Forgot to mention to take NO notice of the "Here's how to fix it" link on the channel list page, it's BAD advice as it takes no notice of possible faults anywhere (including your system) or Engineering (and their "auto" check isn't always correct), the transmitter is still listed for Planned Engineering as per the post just before your first.
Clearing old tuning and doing a manual tune is always the best method of ensuring you are correctly tuned.

Thank you! I tried the manual tuning and the maximum channels that managed to upload was 25. Therefore, the manual tuning didn't solve it unfortunately.
I've reset the tv and completed auto tune and now is back to 101 channels, but as per initial post, main channels sync has the BBCs, ITVs, Ch4/5 don't work at all, only the digital channels.
Will call the flat management to see what the resolution is. As I don't think it's the TV.
Any other suggestions are welcomed. But may have to wait for this work to be done maybe.

They are all "digital" channels! I assume you mean it's the HD channels that don't work.
If you only managed to load 25 channels with manual tune, it sounds a bit like you may have only tuned one multiplex. There's no good reason that an automatic tune would have found more TV channels than a manual tune of all the UHF channels. Actually it's normally the reverse. In cases where (for whatever reason, fault etc) where there may be weaker signals, the automatic tune cna miss then and a manual tune will find them.
Can you tell me which 25 channels it loaded, when you tried manual tune?
It's sounding like there could be some very intermittent connection here. Works (badly maybe) one minute, then not the next.
Did you try swapping/changing that flylead/patch lead from the wall plate to the TV?
Is there more than one socket on the wall-plate? If so are they labelled?
Without clearing your now current tuning, try adding a manual tune to UHF channel 47. This is the HD multiplex carrying the HD channels.
Select Home/Menu button. Scroll to Settings. Select Installation or Tuning. (what it shows is model dependant). Then Select "Manual Channel scan". Follow the menu and enter UHF channel 47 when prompted for the channel number.
Can you give the Strength and Quality/error figures for the TV channels I suggested before -
eg. 1, 3, 101, 16, 11, 12, and 7
Without some of this information we are clutching at straws here.

jill:
You shouldn't have any problems with reception in your location BUT the Oxford transmitter has been listed for Planned Engineering for a few weeks.
If you made the unfortunate mistake of retuning when you had no signal, this will likely have just cleared your correct tuning.
You cannot tune to signals that aren't there or are badly pixellated and can't be decoded
I assume you mean the Create and Craft TV channel at LCN85 which is carried on the ArqA/COM5 multiplex, so I'd expect you to be missing other TV channels such as Sky Mix LCN11, Sky Arts LCN36, Film 4+1 LCN47 and others.
If so, your best bet will be to do a MANUAL retune (go into your TV settings) for Oxford UHF channel 37.

Chris.SE: thank you for your previous reply. I have tried a manual retune in CH37 but a message says No signal. When will work finish on the Oxford transmit and viewing return to normal.

Jill:
Just for clarification, were you missing those other channels as well? Or is it just Create and Craft?
I'm afraid Arqiva never provide details of the engineering work or how long it may last, some of which can be weather dependant.
I don't suppose there's any chance your loft aerial has been disturbed from its normal position?
Recently, anything external that may disrupt signals - scaffolding, solar panels, metal flues etc.?
After another check, I see you should have had a postcard from Restore TV, to check, put your postcode in https://restoretv.uk/post…ure/
It's possible you may now be getting interference from a new/upgraded phone mast which won't always have obvious/immediately noticeable effects on all multiplexes. So if this persists that is worth pursuing for the Free Filter.
Do you have any amp/splitters to feed more than one TV/box?

Transmitter engineering: you have been working on this since April when are you going to finish.. I didn't have any problems before now I either loose channels or they are so distorted you cannot watch or record them. Having just renewed my tv licence I am not happy with service I am receiving. Two months of disruption is not acceptable.. when will my reception return to normal.
Regards Jill

Jill F3nemore: This is an independent technical help website, nobody here has anything to do with any engineering work. Unfortunately Arqiva (the company who operate the transmitter) don't usually give any details of what works they are carrying out or when they are due to be completed.
