To deal with the problem you must clear the channel list completely and then rescan - if your box has it in the menus, please the 'installation menu' to do an initial scan or a reset to factory settings or First Time Installation. You MUST delete the entire existing list of channels. On most boxes this technique can be also be used:

Try this:

1) unplug your Freeview box (or idTV) from the mains;



2) unplug the aerial from the Freeview box by disconnecting the cable from the 'RF in' socket;



3) wait 30 seconds;

4) plug Freeview box (or idTV) mains back in;



5) do a complete scan for channels - it will fail without the aerial. (This may be in the installation or initialization menu, and is distinct from any 'add channels option'). Once this is done your channel line up should be empty;



6) reinsert aerial by reconnecting to the 'RF in' connection;



7) do a complete scan for channels again.



The Freeview channel line-up provided by six "multiplexes" - each of which carry five or more TV channels, radio channels, text services and EPG data. In this diagram each ROW represents a multiplex. If you are still missing a whole multiplex (ie everything on the row) you may need to replace your aerial with a wideband type, purchase a larger aerial or you may have interference from a VCR, games console, Sky Digibox or similar.

Hayley: Mendip is one of quite a number of transmitters listed as having ongoing engineering works:

I suggest you use manual tuning to restore the channels. Automatic tuning, as well as deleting everything already stored, goes through all the broadcast channels -- with manual tuning you can scan just those used by Mendip.

There are six multiplexes, each of which is a single signal which is on a particular broadcast (UHF) channel. The full list of Freeview channels is here, along with which multiplex ("mux") each is carried on:

Channel listings for Industry Professionals | Freeview

The UHF channels for the six multiplexes from Mendip are:

PSB1 - BBC A - C32 (BBC standard definition TV and radio)
PSB2 - D3&4 - C34 (ITV1, Channel 4, Channel 5 and some sister channels)
PSB3 - BBC B - C35 (all HD channels, BBC and non-BBC)
COM4 - SDN - C48
COM5 - Arq A - C33
COM6 - Arq B - C36

The manual tuning screen may give indication as to strength and quality of the signal. Enter/select the UHF channel number and give it 10 seconds or so and see whether it gives indication that there is a signal there. There might be but it's at too a low a level to resolve a picture. Having left it 10 seconds or so, try scanning the UHF channel to see if it can pick up the programme channels.

Some TVs have a built-in amplifier/booster that can be enabled, usually by individual channel. If there is such an option within the on-screen settings and you cannot get the TV to tune without it on, turn it on and try again. In some cases the amplifier may be called 'LNA' (low noise amplifier).

If your TV has an amplifier and you manage to get it tuned without the amplifier on but the picture breaks up, try turning the amplifier on to see if it makes things better.
