I've done a hard reset, the screen still was black. Sound still works, which is how I even knew it was still on and not dead in the first place. I'm unsure how it happened, I plugged it into the charger before I went to bed - placed it on my desk and that's all. Noone touched it, Noone threw it: it wasn't even splashed with water. It was just there on my desk charging.
So when I woke up to play it, all of a sudden the screen wasn't working but the sound was.
I will try and see if I can attach a video here as well, if not then I will upload to YouTube and put the link here.
