Dark display after replacement, possible broken logic board?
Hello.
I replaced the display assembly yesterday. After some trouble with white streaks, I tried to clean the contacts with both oxide cleaner and bandaid-cleaner.
Now the screen is dark, and the phone vibrates in sequence when connecting the power supply.
I tried to connect the old display again, but still the same.
I have also tried to recover through Itunes without luck.
Could the logic board be damaged while cleaning?
Does anyone know if it's possible to get a replacement logic board?
Is this a good question?
