Backlight only no Apple logo or screen after screen replacement
I just replaced an iPad Air 2 LCD and digitizer but the display is only showing the backlight. I’m getting no Apple logo or any thing showing on the screen. I have also discovered when I push down on the longer LCD cable connected to the logic board I hear Siri chime. I can hear the click when pushing sleep wake but no matter what I do no display. I have tried reseating the cables, a hard reset as well as connecting the old damaged screen (minus the home button) but to no avail no screen.
Update: I should clarify the old damaged screen works but has lines all up and down it. But it does actually display something whereas the new screen shows absolutely nothing.
Has as anyone else experienced this?!
