Why is it grey?

[RedlipsAndSlippers]

When I left for work this morning there was nothing wrong with the tv, but by the time I got home something weird had happened. We have sky, but the screen is all in shades of grey.
When we run a DVD it comes out in perfect colour, and when the turn the sky off the blue screen is still blue, so I don't think it's the tele. We've tried the obvious, turning the box off and on, unplugging, changing the scart lead, but whatever we do, all sky channels are in grey.
Anyone got any ideas on what may have happened? Really don't want to have to shell out for someone to come and tell me I need to spend money on it, I haven't got any to spare!
Thanks :)

Ring them, they're fab at fixing stuff over the phone.

Really? When our sky Internet router melted (scary!) they agreed to send us a new one, but only if we started a new year of contract with them, otherwise it was going to be something ridiculous like £70 to get a new one :/
Just worried that it'll be the same scenario, and since we have another little one due I don't want to lock myself into something that I may not be able to afford in the long run.

I'm in Ireland but I generally seem to be speaking to someone with an English/Scottish accent so it's probably the same call centre and they're always really helpful. They can tweak things from their end and diagnose the problem.

Have you tried fiddling with the wires at the back of the box. Ours goes funny sometimes and it's usually just a loose connection

Check cables are plugged in. Check settings on TV remote. On ours, we have 4 coloured buttons. One of them for Virgin box, another for wii. If pressed once, we get b & w, press twice for colour.

Yeah, DP has checked all the wires and stuff.
Guess I'll have to make the call tomorrow. Hopefully some of your positivity will rub off on me! Thanks :)

Littlefishes you genius! Had taken DPs word for it that he'd checked the settings with the tv remote already, but it's worked! Thanks :)

I had the same problem every time we switched from wii to tv or back again. Eventually my kids showed me what to do!

& I take it you still gave the old style TV like us, then?

gave > have

It's certainly not the newest Thanks again, I am now the techy one (the only time that's ever happened)
