Not working after screen replacement
Had a cracked screen on iPhone 5, so replaced it.
Switched it on and left side of screen was white, right side black.
Opened it back up and checked everything again, but now nothing happens at all?
No lights, no Apple, no noise or vibration, just blank.
Now I'm going blind from squinting at small screws and parts and having a minor tantrum, any ideas before I start chucking it about?
