Tim: Thanks for the update on the final situation and pleased to learn that all is now OK.
However on the subject of the booster, that's why I brought it into the equation emphasising about trying its power off test AFTER the picture went faulty, because trying the test whilst the picture was OK wouldn't really have shown any fault up as it was obviously working then, but if the same test was tried after the picture went downhill it wouldn't have made any difference by switching it off, this positively indicating the fault being associated with the booster circuit, which in this case was its power supply failing on a regular basis through thermal reasons, likely because of nightly heat build up in the loft.
Main thing is though that all is now OK!

Lawrence: Well in November they should be going up from 4Kw to 100Kw after channels that would be presently affected on a distant transmitter are cleared.
You cant really get boosters that can do as you were enquiring about, and all I was really meaning was that its far easier to obtain a happy medium if the booster being used is variable.
I really don't think it worth the cost though, as any booster purchased is liable to become redundant come November.

Lawrence: Just a point of clarification, the distance your various TV's are from the booster doesn't really come in to what I am referring to, which is trying to stop a powerful signal from overloading a set whilst at the same time not reducing other stations that are already weak.

Ricci: The spec I read on that model suggests that it cannot actually receive Freeview HD transmissions as the tuner is only shown as being a DVB-T type.
Have a check though on your user manual in the specifications section, as unless DVB-T2 is seen then it wont be able to receive HD, only showing HD images via an HDMI lead from some other device.
By the way, sets with DVB-T tuners will just ignore an HD signal whilst tuning, this making it appear as though nothing is there, HD from Belmont being on Mux Ch28 should you want to try a manual tune.

aaron: Stamford is, and always has been, a relay of Waltham transmitting Central TV programmes.
What I suspect is misleading you is, that in areas North of the Welland that are climbing up slightly from the waterfront levels (Broad Street / West street upwards) generally has their aerials pointing at either Waltham or Sandy, and if its Sandy they will be pointing very roughly in the same direction as for the Stamford relay, albeit it requires the aerial to be mounted vertically.
The problem there is that when they retune their TV's / boxes on auto-tune their devices will lock onto the stations nearest to the start of the tuning point, which will be Sandy on high power Mux Ch27, whereas Stamford is Mux Ch47, and as such if actually picked up will be in the EPG 800 ranges.
The Sandy transmitter is reaching many places in Stamford that analogue didn't, and its most likely that which is misleading you.

Richard: Taking it that you are referring to EPG Ch50, try going into the signal check screen (condition on some Panasonics) and note what Mux channel number you see, as you might find its Mux Ch47 HD from Sudbury / Rouncefall, as according to my info HD isn't transmitted from Tacolneston until November 23rd.
(The trade reception predictor does though indicate HD from Sudbury/Rouncefall as being possible for your code area)

aaron: Just to add, Anglia (Sandy) ITV being
on Mux Ch24 whereas Stamford is on Mux Ch41, likewise Anglia's HD service on Mux Ch21 and Stamford on Mux Ch44.
Anglia always taking up the EPG3 position (when received) over Stamford.

Rhys brooks: This can be simply because no two brands of receivers are the same as far as sensitivity is concerned. It could also be made worse by the method used to provide the extra sockets, as they shouldn't really be looped in the same way ring mains power sockets are done unless in a strong signal area, even at that its much better for each socket to have exactly the same signal, meaning that they should be fed as individual outputs from a powered splitter.
Just to test if its is a sensitivity issue, try one of the problem sets on the living room socket, if its OK there then what I mentioned about a powered splitter is the only answer.

Ricci: Yes, quite correct, as I managed to have a look at the more detailed spec and it does indeed state what you have said.
And as previously mentioned give it a manual tune scan on Mux Ch28, but if still nothing try a signal strength/quality check on either Mux Ch22 or Mux Ch25 to see what is indicated, as both these transmitters are on the same power as the HD one on Mux Ch28.
Another aspect that has to be taken into account is regarding your aerial, should it be roof mounted coupled to a booster take the latter off, as your signal could be on the verges of blocking the tuner input, as I am aware that Belmont really blasts in on quite a number of locations in a line between Lincoln and Newark, (and further afield!) although whats said obviously only applying should HD still not work.
Looking forward to update on outcome!

John Fuller: If referring to the Mux channel that Ideal World / ITV4 etc is on, its operating on a much lower power than the main stations and with many areas North of the transmitter such as yours finding it difficult receive, try a test by manually tuning Mux Ch67, as its temporarily operating on that channel number until 14th of September.
