iPad Mini 2 screen keeps going black
My mums iPad mini 2 used to do this thing where there was white lines appearing all across the screen and recently it stopped doing it, but then the screen started going fully black. The thing with the lines could be easily fixed by pressing the on and off button (sleep/wake) and now her iPad screen keeps going plain black. I'm not sure if they're related cause it still does the line thing every now and then, but the screen keeps going black and she can't do anything on it. Can anyone help? If you need more information please ask.
