Hello!
My neighbours iPhone is only showing these black and white stripes.
When I change the display it's not showing anything (and I tested the new display on my own phone it definitly works!)
The old display sometimes shows these black and white stripes and sometimes it turns full white then black again.
My PC however seems to recognize the iPhone and it's also showing up on iTunes.
But it seems that I can't find a fix for the screen problem.
Here is the screen:
