Forgot to mention to take NO notice of the "Here's how to fix it" link on thechannel list page, it's BAD advice as it takes no notice of possible faults anywhere (including your system) orEngineering (and their "auto" check isn't always correct), thetransmitter 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.

Chris.SE:

Thank you! I tried the manual tuning and the maximumchannels 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 thedigital 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.

Ben:

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 onemultiplex. 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 thewall 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 Channelscan". Follow the menu and enter UHF channel 47 when prompted for the channel number.

Can you give the Strength andQuality/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.

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 loosechannels or they are so distorted you cannot watch or record them. Having just renewed mytv licence I am not happy with service I am receiving. Two months of disruption is not acceptable.. when will myreception return to normal.

Regards Jill

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

Sorry we seem to have missed your post the other day, probably because of all the spoam that's appearing.
Your issue is most likely because of current weather conditions.

High pressure could affect reception across the UK this week | Freeview

It is NEVER advised to Retune if you were correctly tuned and haveNO Signal.
In these sort of conditions it will often clear your correct tuning and can tune you to the weak signals from a distanttransmitter which will eventually disappear!

You cannot tune to signals that aren't there or can't be decoded.

If you now have the incorrect tuning, clear the current tuning by unplugging theaerial and doing a full retune, then plug the aerial back in and do a MANUAL tune of the UHFchannels as listed at the very top of this page although if you can receive a Local mux you may find it onC22, it depends on your location for which we'd need a full postcode to advise further.
