Help! Sound went on TV and picture has gone greeny-blue!

Found 10th Jan
I've made sure all the cables are plugged in properly at the back and after five minutes, the sound spontaneously came back on but the colour remains. Any advice would be appreciated! Thank you

I can't stand it, so no, lol

1) Do you receive your TV signal from a tuner built into the TV, or externally from a Sky / Virgin box or similar.
2) If internal tuner: are the same symtoms present when you attempt to view an external source such as bluray player, media box or similar?

I know what the problem is I think

Are you able to view any other source, such as internet stream or movie / image from USB?
And I assume you have power-cycled all items?

I have a Chromecast but can't remember how to use it. I'm a complete technophobe.

And yes, it could be a dodgy scart lead.

Powercycle all items. If still having same issue and scart lead has same connector both ends, remove scart lead from Sky box & TV, then invert connections so that the connector that was originally in the TV is now in the Sky box (that will not resolve an internal Skybox / TV issue but it may beneficially change mechanical forces on a questionable scart cable). If no different after cable reversal, you need to find a way of displaying another scart and non-scart source to assist in any further diagnosis (or test the Sky box and same scart lead on another display).

Thank you Andy, I'll try inverting the scart first.

...and by "powercycle" I mean at the mains socket, don't just turn off/on using the devices' power buttons.

what happens if u take the scary lead off all together does it stay green or go back to normal that should tell u if it's the tv or if it's something else. if tv goes back normal it's probably the scary or wiggle the lead it may not be on properly but u probably done that already.

lol scary * scart lead

haha scary lead give me such a giggle, thought I'd missed the bit where squiff had actually described it as that.

Sometimes cheap scart leads have 'soft' prongs. Eventually the weight of the lead pulls out slightly to one side causing a missed contact or two. You can, using a pair of needle nose pliers, twist each one a fraction (not to much or you will snap it) this will ensure each one makes contact. If this works you need to replace with a better quality lead as soon as possible.

Had that before on a sky box, Press and hold backup, Turn off at mains for a 10 second, Turn back on keeping hold of backup and all lights should come up, Let go of backup and wait for it to reset.

Thanks everyone. Just got in but will try all suggestions and check the scary lead properly very shorty and will get back to you.

No, it turned out not to be the scary lead but the (coaxial?) cable.
