Fixed iPhone, tried turning on, worked, then stopped
Okay, I replaced my screen and battery. I also cleaned up all the corrosion around the connectors (but not inside logic board).
So I put everything back together and hold the power button. The Apple logo came up for 2 seconds, and then disappeared. Now, I connect my iPhone to the computer and it connects, but I cannot see anything on the iPhone screen.
Would it be my screen that shorted out? or would it be the backlight IC in the logic board?
I kind of peaked into the logic board and it looked kind of corroded around the area where the backlight IC is, but when I turned my iPhone on after replacing the screen, the Apple logo was bright.
Is this a good question?
