Hello
I am repairing an iPad 3 digitizer.
After removing the broken digitizer, I was testing the new parts and all was well at that time.
Don't ask me how, but I almost dropped the unit during this testing phase. No adhesive was applied, and it basically fell into the three pieces while turned on.
The LCD display cable came unplugged while the unit was powered on.
At this point, the device does not display anything at all now.
How do I determine if it is the display or the logic board that has failed?
