Chosen Solution
Just wanted to see if anyone else experienced the same issue I am having. The original digitizer was cracked on my mini 2 retina by my wife. I ordered and replaced the digitizer from one from iFixit. That digitizer died after a year of use so I got a new one via warranty. After installing the new digitizer the back of the iPad now gets hot with use, where the logic board is located. Does anyone have an idea what would cause this?
Have you already sealed the digitizer? If not, then I would double check the steps by following the guide. You may have damaged the connectors, or pinched the flexes on the digitizer. I would also inspect the battery connector and surrounding components. If the iPad seems hotter than normal, it’s because something is drawing excessive current. This could be a bad modular component or it could be a logic board issue.
