Th screen stays black after a digitizer replacement.
I successfully replaced the digitizer of a customer's iPad Mini with the soldering method.
I connected everything and tested, and it was successful except for the home button. I disconnected the digitizer flex and the screen flex and the battery also. I wanted to test again and connected everything. I tried to turn on the Mini, but only had sound and no screen. The screen stays black.
iTunes recognises the Ipad Mini, and I did a DFU in hopes that it would work, but no success. NO SCREEN.
What can I do? iTunes says the battery is 100% charged.
