Vertical lines appearing on display 3-4 times a day.
Hi. My niece just bought a used Iphone 8 plus and was told that just before receiving the phone, he would put a new display on it. Soon after, the phone started showing black and white vertical stripes a couple a times a day, and seemed to fix itself. Here is a photo:
I took the phone apart and had a look. Found broken glass pieces from the former display i would guess, cleaned that all out. Then I took a look at the connectors and the flex cables and everything seemed fine. So I tried turning it back on and everything seemed to worked fine, I had the phone for half a day after the cleanup and I checked the display multiple times and it was always working. But shortly after returning the phone to my niece it started to show these white, black and green stripes.
I am baffled. Is the LCD broken? Or maybe a bad chip. All help would be greatly appreciated. Thanks!
