The symbol shows the location of the Black Hill (North Lanarkshire, Scotland) transmitter which serves 940,000 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.

Are there any planned engineering works or unexpected transmitter faults on the Black Hill (North Lanarkshire, Scotland) mast?

Billy: While works is a possible cause, another could be the presence of a new mobile phone base operating in the band, a band which was previously used for TV. Restore TV [ https://restoretv.uk/ ] is the organisation responsible for addressing problems of to TV caused by these base stations. It says your postcode has received a postcard telling you that you are in an area that could potentially be affected. This isn't to say it will definitely be the reason for the issue because it isn't an exact science. Contact Restore TV and they should send you a free filter.

Billy:

As noted in the post before yours, the is listed for Planned and has been so for several weeks now. Arqiva never provide details of the work, what it involves or how long it may last, some of which can be weather dependant.

IF you are suffering from a new/upgraded mobile , then it's more than likely that your could be affected by the more recent engineering.
As noted by Steve, your postcode should have received a postcard, checked here -
https://restoretv.uk/post…ure/ so contact them for a Free Filter.

It sounds like the mistake you've made is to rescan/retune when you had , you cannot tune to a signal which is not there, the usual effect is it just clears the correct tuning that you previously had.
Also, your postcode is predicted to receive more than one transmitter, so to check that it is Black Hill that you should be receiving, check that your is pointing at compass bearing 99 degrees - that's just 9 degrees south of due E, and the aerial rods (or squashed Xs) should be horizontal.

If that's correct then your best option will be to MANUAL tune each of Black Hill's UHF .

As listed at the top of this page, Black Hill's UHF channels are , , , , , &
(where C means UHF channel).and that's in the order
BBCA/PSB1, D3&4/PSB2, BBCB HD/PSB3, SDN/COM4, ArqA/COM5, & ArqB/COM6.

For which TV channels are carried on which multiplex see
Channel listings for Industry Professionals | Freeview

If the signals are still weak, you may have to try manually retuning a given channel several times over a period, until you get them all back. Once you have a particular multiplex retuned do NOT retune it again (or do an automatic retune).

Apart from the possibility of interference causing your set to "see" weaker signals, your aerial installation may have issues, check that it's still pointing correctly, that the downlead isn't flapping in the wind, check all your accessible coax connections for corrosion or water. If you have flyleads between aerial connections and equipment, check these haven't gone faulty.
