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:
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.

David Hewitt: There's no work indicated as taking place at Winter Hill this week. You could give at800 a call to see if the issue coincides with a new 800MHz 4G base station coming on air. Channel 59 is closest of all Winter Hill's to the 800MHz band which is C61 upwards.
With reference to resetting and retuning, Einstein said "Insanity is doing the same thing over and over again and expecting different results". If the box is tuned correctly -- i.e. to the right frequencies and therefore correct transmitter -- then it will give you the best picture for the signal being fed into it.

David Hewitt: You havn't given a postocode, so we have no idea where you are in relation to the transmitter.
BT boxes etc are all Humax, which are known for their sensitive tuners - so are Panasonics! Could just be that your signal strength is a little on the high side for the tuners. Check your signal strength. Your TV might just be less sensitive.

m.whitbrook: Re: Picture break up only occurring during winter months. On having read through your various postings made on this subject, I note that in your Jan 12th @ 7.47am posting you reported that both your kitchen TV and also the one used by your son, both of using indoor aerials, also break up, should this still be the case? then it would be interesting to know the result if you temporarily connected your sons TV into the roof aerials outlet socket.
The second point being. You also state in your 4th Feb @ 10.27am posting that an attenuator did not make any difference to the situation, what value of attenuator did you try? because at only 5 miles from the Sutton Coldfield transmitter and with (according to info on terrain) a clear line-of-sight from same, any attenuator under 12dB or so is not likely to make any difference as far as excessive signal level problems are concerned.
However, if you still have the attenuator? then no matter what its value might be, there is a test you could try that would give you an idea as to whether or not your problem is definitely being caused by a slightly over the top signal level, although the test will only work if whatever you are using is capable of indicating the "quality" of the signal and not just the strength, the former being essential for the test.
The procure being, connect the roof aerial directly into the TV (or box) and select BBC (or ITV) then carry out a signal check on the levels received, making a note of the "exact" quality level being indicated, that is if its not diving up and down? which of course makes things slightly more difficult.
Once the quality level has been noted insert the attenuator in line with the aerial lead and note if the quality has improved any, if it has (even if only fractional) then this is a positive indication that the signal being fed into the TV (or box) is a tad on the high side.
