Sky not working, HELP

[Dracata]

Sorry if this is the wrong forum, doesn't seem suited to Networking etc!

SO. I moved into my new flat today. Sky engineer arrived, put in our shiny new Sky HD box and connected it to the TV. It worked, he left, all was dandy.

We needed to move the TV Stand, and the coax cable was all tangled, so I powered everything off, unplugged, moved stand, plugged it back in. Nothing more, didn't stretch/bang it or shove it in too hard, put it back exactly where it is.

Now I'm just getting "No satellite signal is being received"

I googled and it said check your signal strength, but I can't find out how to! all the guides on the interwebs are from Sky/Sky+ but the Sky HD interface is quite different and i'm not sure where it should be.

Help?

Edit: Oh and it must *kind* of be working, because I can get all the tv listings, guide etc. If I unplug the coax completely I get nothing, with it plugged in I get all the channels and what's on/when, just not the actual picture!

is it raining?

Nope, clear and lovely outside. I wondered if it was the weather, but it hasn't changed, and seems too much of a co-incidence.

Does anyone have any idea how to check signal strength on a Sky HD box?

It seems to think the signal strength and quality are very high? Picture to follow.

Edit: Thanks, by the way.

When you say unplugged, did you remove either of the f-connectors?

Not quite sure what the f-connectors are, what are they?

The only thing I unplugged was the black coaxial cable, and I carefully put it back in the same connector.

if you unplugged the white cables, have you put them in the right holes?

there are 2 white cables, try them the other way round.

There's only one coax as our block of flats only give you one feed. This mean that everything works fine, but you can only record the channel you're watching as Sky+ recording needs a second feed to record a second channel. Our flats have a notice about this on the website, and the engineer also said its fine.

So there's one black coax cable going into a connector. I tried plugging it into the other connector for the hell of it, but then I get absolutely nothing (no tv listings etc)

At the risk of sounding like a PC helpdesk:

Have you tried turning it off, leaving it a minute, then turning it back on again?

Yup :/
