Colour issue with Sky box

[Jspencer00]

Turned on the Sky box after about 12 hours away, the screen is now only red, blue and black. Everything else is technically working (I can navigate between channels and the sound is fine) but the colour is completely off. Switched to a different HDMI cable but no luck. Any ideas?

@Jspencer00  Have you tried restarting your Sky Q by turning the power off, waiting 30 secs, the power back on?

I had a similar issue on my box today . 

Only thing I found that sorted it out after doing all the on /off shake it all about nonsense is changing the the picture mode on my TV . It's a hisense TV and the only picture mode that solves it is film.    As I cycle throught the picture modes like sport,vivid,film ect the only one that displays the sky picture is the film mode .

Give it a go may solve it for you

That looks like a TV issue to me. Do other devices (in the same port) work ok?

Just had this issue, and this resolved the issue, thank you. I also have a Hisense TV so not sure if there's been firmware updates recently thats caused it.

Just had this issue as well (Sky Q mini and Hisense TV).  Just posting in case anyone else comes across this issue in future.  This is the troubleshooting I done in order as I'm not sure if any of the steps helped in advance of turning everything off at same time.

1. Tried changing picture mode to FILM and yes, that brings the picture back, but refuses to work correctly on any other picture mode.
2. Turned off then on the Sky box.  No success.
3. Tried changing various picture settings on the TV with no success.
4. Under Picture Settings --> customise picture settings --> Reset standard settings then after resetting, I applied to all inputs.  Still no success.
5. Turned everything off at wall (TV and Sky box off at same time).  Left for 5 minutes to make a cuppa. 
6. Came back and turned everything back on again and voila! Picture mode settings working under all options (Standard, Film, Vivid etc).
