Dead spot in new digitizer. Replaced twice. Dead spots.
Customer brought in an iPad Pro 12.9" with a cracked screen. I replace the screen and soldered the new one on properly 100%. Customer has issues with the dead spot on the screen. So I ordered a brand-new digitizer assembly and install that one. Exact same issue as the first one. Anybody have any suggestions? No apparent damage to the control board and soldering is good. Thanks!
Is this a good question?
