Dave Lindsay: Thanks Dave! As I see that david's original posting was made under the "Freeview modes - a simplified explanation" heading.

david durney: The only qualification I will put on what was originally said is that it depends up to a point on whether or not the signal you receive crosses the turbine blades in a diagonal fashion, as if it does then obviously the chopping effect of the blades would be of a higher and "erratic" intensity, this adding to any problems that you may experience.

mary owen: Mark Fletcher's request for your location (post code) was simply because you did not indicate whether or not your reception problem involved satellite TV (Sky or Freesat) or Freeview via a normal aerial.
However as you appear to be using a Sky+ box then press "services" and you will then see the main menu with "options" being highlighted, highlight the "settings" menu using the right arrow button and press select, then using the left /right arrow buttons scroll to "signal" and press select, this will then display the signal level indicator bars.
If the bars are indicating around the equivalent of 50% or under then the dish is slightly out of alignment, as 60%+ is the norm for reliable reception.
Further info dependant on results.

ian from notts: Although either device could be at fault I would suspect the TV as being responsible, if your TV has more than one HDMI input have you tried it in the other HDMI inputs?
If though the TV only has one HDMI input I would try resetting it to its factory default setting, and should this make no difference then try unplugging the Sky box for 30 secs or so before reconnecting the mains plug, as there isn't a single answer to this type of problem because its not a user setting issue.

Matt Jones: You do not actually require a card in a Sky box to view the majority of "Free to view" channels (if this is what you are meaning) with only an odd exception applying like Sony TV (157), sometimes though your box will default to a main region as far as local news channels are concerned if its been unplugged from the mains supply.
The other point being that you will require to have a quad LNB fitted to your dish if its only a dual output type, quad LNB kits being available from numerous e-bay outlets for around £10.00 or so.

Dave Lindsay: Thanks again Dave! and nice to be back, because terrible as it might be to say but I am not exactly a holiday type person.

Alan Clark: Thanks for the Heathfield TX report, the transmitter being located @ approx 12.5 miles / 345 degrees from your residence, the only unknown aspects being:(1) is the aerial referred to loft or roof mounted? and (2) are you using a passive (non amplified) splitter to feed the four TV's?

Maurice Rowley: It depends on what brand of Sky HD box that you have? as Thomson HD and Sky+ boxes are notorious for power supply problems of exactly the nature you have described.
Although in general terms the power units fitted into most Sky boxes do not take kindly to operating in excessively hot environments as they are inclined to run on the warm side at the best of times, this causing the electrolytic capacitors to dry out which results in a low voltage being supplied to the tuner, this on many occasions dropping out resulting in the "no signal" warnings to be seen.
Regarding the component at fault, if the box starts to operate again on being cooled down then its likely to be the voltage regulator IC, possibly (but not guaranteed to be) by it not being bolted sufficiently tight enough onto its heatsink.

jim: Nothing done at a transmitter can damage anyone's box and so your problem has to have an element of the coincidental attached to it.
However a better assessment of your situation cannot be made without knowledge of your location (post code or one from nearby) as this would then enable the signal levels expected in your area to be assessed, as if the signal level received by a box is running at either the top or bottom end of its operating range then even very slight changes in signal strength can cause its tuner to cut out, and so it would also be of assistance to know the model of Freeview box that is being referred to as tuner sensitivities vary between brands.

david durney: Your original posting was made on August 11th @ 10.07am and which I replied to at 3.29pm, a copy of pasted below.
>> I will be very surprised if they dont! and that is irrespective of where (distance from wise) they are located between Sudbury and yourself, as in some areas where Freeview reception has been ruined by these grossly inefficient abominations the energy company involved has provided Freesat installations to the viewers affected at no cost to themselves, not of course that I consider that adequate compensation for the loss of such a flexible system as Freeview where the one aerial can feed a number of devices, unlike Freesat that requires a separate dish feed for each location. <<
The only qualification I will put on what I said is, that it depends up to a point on whether or not the signal you receive crosses the turbine blades in a diagonal fashion, as if it does then obviously the chopping effect of the blades would be of a higher intensity.
