iPad 2 A1395. I replaced the digitizer and the new digitizer works fine. But I found the following two problems: Home button stopped working no matter how hard I try;iPad is not charging properly. When plug in the cable there is no charging icon. However, after a while I can see the battery percentage ramps up, but very slowly, like 2% - 5% per hour when the iPad is on. If iPad is off and I plugged the cable the iPad would turn on as expected, but there is still no charging icon. I did broke the wifi antenna when trying to pry open the digitizer - the part close to the screws are torn off. But wifi still works so I guess that should be OK? Could it be a bad docking/charging connector? The connector does affect the home button as well, right (since there are two connection points)? Or can it be a bad connection cable of the digitizer? Thank you for the help in advance.
This is not a problem with the digitizer. You said yourself that the digitizer works fine. First, make sure all your connections are secure. The problem with the home button is likely that the bracket covering the home button is not secure. It could either be in the wrong spot or it might not be attached to the screen enough. All the home button does is press on a pad underneath it to register a click. As for the charging problem. Not sure what might be going on with that. Maybe the cable isn’t pushed in all the way or loose. You could have also accidentally damaged the ribbon cable when you where taking the screen off.
First of all it sounds like you bought a bad digitizer. You should use this one from IFIXIT. iPad 2 Screen Digitizer Don’t repair anything else until you replace the digitizer. After you replac it let me know what started working and what didn’t so we can work from there. Good luck.
