iPhone screen went black but is on
I was using my iphone 5c just a moment ago and was on facebook, then the phone locked up, i couldnt do a thing, then the top quarter of the picture started to do almost like a dissolving thing so that the picture started disappearing, then the screen went blank,
Here's the steps i have taken to resolve this.
Tried turning it off using the power button - Did nothing, screen is still black
Tried holding the power button and home button together - Did nothing, screen is still black
Replaced the screen - Did nothing, screen is still black
Tried plugging it into the computer and doing a reset - Did nothing, screen is still black
However, i can ring the phone and it rings.
So whats the problem? why has my phone randomly died? could it be that the gpu chip has committed suicide?
