Not a new box, had for a year now. It’s a buzz 4000 series. Yes the issue just started now. It’s never happened before. I have tried unplugging from the wall for 30 minutes and still had the same issues. 

My buzztv box is not displaying any light colours ( white , yellow etc. ) I have confirmed it’s only through my buzztv box, as soon as I goto my tv menu or YouTube through my tv the colours are fine. Has anyone had this issue? How does one fix this!!
