I bought a broken Iphone, and replaced the screen. It had black lines that ran down the scree, and the digitizer was screwy. I figured it was the assembly, and returned it and got a new one. Just put the new one in today, and it does the same thing.
iPhone 5, iOS 7.0.4
Apparently there is a different hardware problem.
Like the motherboard?
Could be, but I wouldn't be shooting in the dark.
Take it to a small electronics repair shop that specializes in repairing cell phones along with the iPhone to see if they can determine what needs to be replaced.
What else could it be?
I have no idea. I'm not in the small electronics business - namely not in the iPhone repair business.
Black lines running vertically down the screen?
