Why isn't wifi enabling on my Samsung Galaxy S4?

AC Question

wifi not enable samsung galaxy s4

Strangest fault, can't enable Wi-Fi, Wi-Fi Hotspot or Bluetooth... When I pull down the screen from the top to bring up the quick select enable menu Wi-Fi will not turn on, it is preselected and a very light green colour instead of a grey for disabled or bright green when it is enabled... Holding the Wi-Fi button down and entering the option doesn't help either as it says "turning on" but does nothing... the toggle switch to turn Wi-Fi on also does nothing.
I have reset the device several times and have also now tried a factory reset... which I really didn't want to do and it still hasn't helped. I have searched forums and google for any sign of this same fault and found nothing. I also can't enable portable Wi-Fi hotspot or Bluetooth... Can someone please advise?
