Jeff: Possibly yes, especially as the HD service is on relatively low power. The only way I see you getting over the problem is by carefully positioning the aerial, this not meaning as high as possible but preferably somewhere that an element of screening can be achieved from the offending transmitter.
Sandy at 22 miles on a bearing of 11 degrees, Crystal Palace at 30 miles on a bearing of 155 degrees.

Mike: I have to say that none of the two reception predictors (one being trade) indicate any reception being possible other than from Brampton at 1 mile away.
If you are high up then it might be possible to receive a signal from Stockland Hill, but I don't see you would really gain anything if you did as any signal received would likely only be from Stocklands three main multiplexes on high power, in other words not any more than you presently get from Brampton.
Two of Stocklands commercial Mux transmitters (ArqA & ArqB) are expected to be on low power until some time next year so the chances of picking them up could be quite limited, but if you are prepared to experiment then you don't really have anything to lose, but remember that as well as swinging your aerial around to face towards Stockland Hill to also turn it for horizontal polarisation.
Another point being, that your aerial might be group B (yellow) whereas Stockland is A (red), although for testing purposes this isn't of prime importance, and especially so "if" you decide to use an aerial amplifier during tests.

john Fuller: There is always the possibility
that your LNB is faulty or that the dish has moved very slightly, and you really should start afresh by checking this.
If you acquired another box and there is still a problem then it certainly points to one of the aforementioned applying, if not a cable / "F" plug fault. (short circuit)
Unless you are aware of a particular power surge problem, then I would dismiss this as a possibility.

john Fuller: Just in addition to above, you should use the signal strength / quality indicator on your box (services - 4 - 6) to detect if even the slightest signal is showing, as if it is then although not being enough to resolve a picture it would indicate a dish alignment problem.

phil w: Your location is indicated as being capable of having perfect reception from either Mendip (16 mls) or Wenvoe (18mls) but if you are using auto-retune for your TV it could be picking up the other more local possibilities shown (albeit poor) that use much lower channel numbers.
Try when on BBC1 going into the signal checking menu and have a look at what's shown as well as the Mux channel number associated with the signal, as if its Mendip it should be Ch61 whereas Wenvoe is Ch41.
Also do this test whilst on ITV1, Mendip Ch54
and Wenvoe on Ch44.
Your problem could be caused by other means out with your control, e.g: interference from other stations due to atmospheric conditions etc, but try what was mentioned giving the results.

Nick Madina: The post code provided is not recognised by the predictors, could you please check on this.

Stuart: What you mention is strongly suggestive of either the method used to couple up the PVR, or that your signal is below a level that they can resolve a picture, although this unlikely if experienced on more than one device.
What method are you using to feed the aerial into your PVR's aerial socket?

steve: Having knowledge of your location (post code) would be of assistance to enable signal checking, but what is the model number of the TV or box being used?

john Fuller: Yes! as I think your problem all along has possibly been caused by the dish (or LNB) rather than the box, although if you have tried to carry out the system resetting procedure whilst having no signal then you might have corrupted the software resulting in a real problem, but if its just the LNB procedure you tried then thats OK so long as you followed the instructions.
The main thing is that you will have to ensure that your dish is aligned properly for 28.2 degrees before trying anything else, this greatly simplified if you have access to another box that hasn't been altered in any way.

Angela: When this happens carry out a signal strength check (within tuning menu) whilst still on the same channel, (with blank screen) and also observe if the channel number has changed, or not even there at all!
Waltham (BBC1)Mux Ch61 and (ITV) Mux Ch54.
(that is assuming that you are receiving from there).
