iPad Works on it's Own - Like it's Possessed
An iPad 2 came into the shop I work at with a digitizer problem, the iPad would open apps by itself and type by itself obnoxiously, not recognizing anywhere I touched the digitizer. So naturally, I replaced the digitizer thinking that would fix it.
And because of my luck, it didn't. It still had the same issue, so I replaced it with another touchscreen, and the issue was still present!
Eventually after a bit of research online I decided to do a hard reset, which was futile. And furthermore a complete factory restore on the iPad, which was as useful as the hard reset... it wasn't.
So after multiple digitizers and restores and resets, i cannot do this on my own. I need the help of ifixit users.
By the way, the local private school near the shop I work for; all of their students are required to have iPads. Shop I work for has a deal with the school that we have to fix all of their iPads. This is one of those iPads.
I'm not sure yet as to whether go to apple is an option right now as it's a school owned iPad. So ANY input on how to fix this would be greatly appreciated. Thanks!
OK - So we know the iOS is clean and the digitizer it's self must be OK as you replaced it with the same reaction.
So, the next area to check is the connector its self could be damaged? It's also possible you have a bad contact, try cleaning the ribbon cable using a pencil eraser by wiping carefully with the grain of the contacts. Then use a damp stick sponge with isopropyl alcohol to clean the eraser residue off. As far as the connector its self you might try flushing it with some alcohol and using a dental vacuum to suck up the waste (or have it drip away from the rest of the internals).
If these don't improve anything you have a bad logic board (cold solder joint).
