TykeEL: On going engineering work has been taking place at the Waltham transmitting station for quite some time now and with random periods of weak signals being experienced by many, and so I would suggest that you once again blank out the channels already stored in the tuners memory then once completed proceed to manually tune in each of Waltham's muxes one at a time, and if all are successfully stored then do not under any circumstances be tempted to try another retune at any time as absolutely nothing is gained by doing this, because any channel that results in a blank screen is not actually lost but just sitting under the reception threshold of your TV or boxes tuner, a signal check whilst on the blank screen proving this point.

Steve Morton: Further to what I mentioned regarding your particular model NOT being fitted with an HD tuner, this info being from a technical manual, I had a quick scout around at the various companies selling that model and was quite simply appalled by the constant reference to HD quality being mentioned but without the proviso that it was via the HDMI input.
If you purchased that model purely on the basis of what the supplier advised then you are entitled to either a refund or exchange, reference to this being seen on the undermentioned link (4th article down on the user reviews) where someone else was misled.

Steve Morton: And of course the link!

James: You should carry out a "factory reset" or "default setting" on whatever you are using before carrying out another auto-tune, as dependant of the device being used an ordinary auto-tune does not always completely wipe out the tuners memory.
By the way the alternative to the aforementioned two titles used by some brands is "first time installation".

Judith: Provided that the satellite dish in your neighbours property is 18" away from your fence then he can have it at any height he likes, as restrictions only really apply to buildings such as a garages etc, and so "if" your newly constructed cabin is obstructing the satellite dishes view of approx 28.2 degrees East of South then there is nothing to stop your neighbour increasing its height.
By the way what's said only really applies to non-conservation areas, as rules can vary from area to area in the case of the latter.

matt: Unfortunately your link does not seem to work, at least with me anyway, so could you please supply the model number of the Samsung in question.
Regarding your query about requiring a booster, I very much doubt if this aspect is in any way connected to your problem and neither does the "dish" referred to, as the info provided suggests that you are receiving from the Emley Moor transmitter, the frequency given being the BBC mux.
It would also have been of assistance if you had provided your location, this in the form of a post code or one from nearby (e.g: a shop) as knowledge of this would enable access to the reception predictor.

matt: Thanks for the updated info and especially with regards to your location, because by residing at just under 8 miles from the powerful Emley Moor transmitter could suggest that the exact opposite of what you were wondering about is possibly the answer to your problem (i.e: an attenuator) as it might possibly be caused by your TV's tuner being overloaded by an excessively strong signal as Samsung tuners perform very badly with even the slightest overload, the other problem being that this also results in false strength / quality indications to be seen on any signal check carried out and is caused by instability in the system used to measure the signal.
The way to verify if this is the cause (or not) of the problem requires the signal from your aerial (unknown) being attenuated, this usually be done by inserting an attenuator (pref variable) in line with the aerial socket on your TV, but purely as a test if you have access to an old set top aerial then plug that in and see if an HD image of sorts is shown, it doesn't matter what the picture is like as its just really a way of sussing out the signal strength in your area, as I notice that the Primrose Hill relay is only about 2.5 miles away and this points to reception problems existing not too far away from your own location.

matt: This is a link showing an example of what I am referring to, and by it being a variable type of device it can be adjusted whilst referring to the TV's signal check screen, insomuch that its adjusted to give a signal "strength" of around 90% max, this level giving a good safety margin from both overload situations as well as dips causing the level to drop down too close to the cut off threshold.
By the way, in overload situations HD reception is always affected before SD, the latter sometimes appearing as being perfectly OK.

sharon: The method used to couple these various devices together depends on the number of scart sockets your TV is fitted with, is it one or two? and likewise is your Sky+ box a standard type also fitted with two scart sockets?

VALERIE: If anyone resides in an area where the signal being received falls off at various times of the day (especially in evenings) then this is inclined to point to the signal received being affected by not only atmospheric reasons but to changes in weather conditions (moisture content) affecting the blocking or reflective properties of any vegetation (trees) that may be partially obstructing (or even close to) the signal path from the transmitter to the receiver, this being something that is "very" difficult to find any effective cure for without a great deal of time being spent experimenting with different aerial positions (not necessarily higher) and even then with there being no guarantee that a cure would be found.
Just out of interest, although you have mentioned as having 100% strength at times (although 95% max more preferable) but what does the quality indicate? as problems caused by the aforementioned reasons is usually revealed by the signal indicating high strength at times but accompanied by large fluctuations in the quality, this being a situation that's very seldom ever really cured no matter what might be done as its basically out with local control.
Just another small point, I realise that you have said that your reside in Wimborne, but it would have been of considerable assistance in assessing your situation if you had provided a post code or at least one from nearby, e.g: a shop or a licensed premises etc as this would have enabled access to the reception predictor.
