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:
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;
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.
hello about my post on break up of my picture on freeview the problem only happens in the winter as we are now in spring its perfect now no breakup of picture at all..does this mean the aerial wants tweeking answers please
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 Coldfieldtransmitter 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.
There has been no tv signal now for two weeks in Benaughlin park, Enniskillen yet we have our licence fee taken from our account just yesterday, what for I ask. They're cowboys here in Enniskillen taking us for fools.
Helen Hassard: In addition to, and as a back up to that said by MikeB, although engineering work has been taking place for just over a week now at the Brougher Mountainstation which covers your area, the work is involved with its DAB and FM radio service and not Freeview.
