Touch screen does not respond, display works just fine
last week my iPhone stopped working, it had greenish stripes and the touch screen did not respond. I figuered I should buy and replace the entire display, which I did. Before I replaced it I tried to turn it off by pressing the home and the sleep button and letting go when it turned black, unfortunately this caused my screen to stay black. (Black but still on).
After replacing the display it still stayed black, so I put in the display of another old iPhone 5c, whose touch screen did not respond. This brought back the stripes and the touch still did not respond.
I then tried out each of the displays on the old iPhone, which brought the same results each time: display working just fine, touch not responding.
So basically I now have three perfectly working displays and two iPhone 5cs, with a touch screen that does not work. (and some other funky issues that caused two out of three displays to stay black on one phone and work on the other)
Anyone any idea what's wrong or how I can fix an iPhone, whose display works, but the touch screen does not?
PS there's no software problem
