Replaced LCD Now have Black Screen
I was repairing the LCD on a Iphone 4 CDMA and unplugged the LCD connector before the battery. I hooked it back up and the screen was black. The phone was on you could see the back light and you could hear it. I tried two other screens and the same except the last one the screen was a little gray. Did I do permanent damage to the logic board? I have tried the reset and it did not work.
Is this a good question?
