One HD channel has no signal - everything else is fine

[Agenais]

My Sky+ box is generally working fine.  But a couple of weeks ago one single channel - ITV HD - suddenly said it had no signal.  I have attached the signal strength pages from a working channel, and the ITV HD page showing no signal on that channel.

All suggestions as to how I can solve this irritating problem will be much appreciated.

I can get ITV. On SD, but obviously prefer HD.

Looks like a slightly misaligned dish

You can contact Sky using the number here (See the "Need more help?" dropdown near the bottom of the page)

Note: Make sure you have the correct country flag selected in the bottom-right of the page

@Agenais  If it's still not working after a couple weeks , all I can suggest is that it might be a dish alignment issue in which case the dish may need moving 

if you can't do this yourself phone sky and book an engineer visit (£65 roughly) or find a local installation company

Seems unlikely to me, since every other channel is fine.  I would suspect this if it was a group of channels affected, as when thunderstorms sometimes affect some channels but not others.  In this case it is one single channel.

As above, I can't see how this would affect one single channels, and even adjacent ones were unaffected.

@Agenais  I know it sounds strange but even the slightest of movement would be enough to knock just one channel off

i think your only course of action is what @Annie+UK  and myself have already suggested

Thanks for your help, which I do appreciate.

i will get it checked - it has been rather windy!

Could be a failing LNB either way a call to sky or a 3rd party satellite installer will be required to trace the actual issue

Having had problems all weekend (bit windy) and checked signal strength on other channels, I am sure you are right, so thanks for your help.  I will visit my local installer tomorrow.  I think the dish has moved (and is wobbling!)
