Hello everyone one of our techs was working on a iPad Pro 12.9 screen replacement today and when testing the new screen the iPad would not turn on at all any more. I put it under a microscope and saw something missing I have no idea what it is. I’m going to attach an image please help me identify what it is and if I can pull it off of a iPad mini, Air etc and replace it? Thanks in advance

Unfortunately there are no schematics available for the 12.9 iPad and I don’t have one laying around either. However what you are pointing to are capacitors around the PMIC so I would say that a missing capacitor is unlikely to be the reason why the iPad is not turning on.
