Hello! I have replaced the digitizer on an iPad Air, and the top rows of pixels are grey after that. It is about half a centimeter of mostly gray pixels, but below that, the screen works just fine. What can have happened? Thanks!
Probably didn’t connect it properly. Could possibly be a bad part iPad Air Screen Digitizer
Your lcd was broken during your digi replacement. That’s what they look like (sometimes) when they’re broken.
