I had this problem yesterday.but now it works fine for me.i hope it never come back 
It's not about updating or Repairing !!! it happend suddenly !!! Sometimes it fix after shutting down the phone but sometimes it remains for hours !!!
I'm requesting SONY's Support Team to ask hardware and developers to find out it's a hardware problem or software problem 
Are you install Go Launcher EX or HD Live Wallpapers ?! or AmbiLight OR ColourBar Apps ?! It may because of them,i'm not sure,i'm asking you to clear it for SONY Support guys 
i'm afraid it's a Hardware problem 
Nobody's here ?! please give us a ture answer !!!
