For you guys that have one of these do you know why my display keeps flicking from this



To this



Sorry for the quality, it's off my mobile.

I hope you can see that it seems to flash so the whole screen is blue, as per second picture (more obvious on the right of the display). It's natural state should be the first picture.

It does not matter what background or movie I have on or even have the entertainment turned off altogether it still does it

Any ideas

Cheers
