A couple of days ago a friend of mine asked me to have a look on her iPad, she accidentally dropped it and hit the ground and after that she iPad’s screen becomes green… unfortunately her iPad’s warranty was already expired and she doesn’t have enough money to spend to have it fixed.
Since that the iPad is working I told her to backup her files such photos, music, contacts, etc. and other important files that she needs before giving it to me.
Before I proceed, I told her that I’m going to hit/tap her iPad a couple of times until the screen return to its normal state its that the only way I can fix that’s why I asked her to backup her files so If everything goes wrong she still have her important files with her.
Depending on the damage on the iPad, I could say something might have been loosened inside the device and needs a little bit of shake to fix it. If after a couple of hits, punches or taps and it didn’t work it means you’re hitting it too lightly or you need a little bit of force to make it work (not too light and not too hard when hitting it).
This method works for me, If in case you want to want to try this method, do it at your own risk and make sure you backup your files first.
