IPhone 6 Black Screen?

Its a black screen and when I tried to turn it on, there's a white blur and a line going down. I've charged it for about 20 minutes and i also see no apple logo

Charge it for a minimum of two hours, then press and hold both the home and power buttons at the same time, for around ten seconds, until the Apple logo appears.

If it does not work first time, leave it another half hour and try again. It's a common problem with all smartphones & tablets if the battery goes totally flat and the device loses the information it needs to "wake up".

Whilst its in that state the battery fast-charge system does not work so it takes ages to get enough power for it to complete a proper start-up sequence…
