sleep/lock button not working after screen assembly replacement
I just got finished plugging in a new screen assembly for the iPad mini 4. I moved the original home button over, put a thin layer of tape all the way around the screen, and moved the black fabric tape from the old screen at the bottom to the new screen. Everything seemed to work fine except the sleep/wake feature. I could hold the power button down to turn it on or off but I could not put it to sleep once the screen was on. Nor could I turn it on when the screen timed out with the power button, only the home button.
So I checked again and made sure that everything was covered up with tape or fabric and it looks good. Then I took the old broken screen and connected it without the home button and the power button worked fine with the old screen. But When I connect the new one, even not glued to the frame, the power button will not work to put it to sleep or wake the device up, only to shut down or off. Can someone tell me what I'm missing?
