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!
