I had to buy a new screen for my iPhone 4 (LCD, Screen Digitizer, etc.). I installed the new assembly, and I turned on the power and the screen was all white, but it was not the "white screen of death". I could barely make out the Apple logo, and then about a minute later, I was at the lock screen and, again, I could barely make anything out. Now i can see better than before, but there are vertical lines and everything looks like it was on negative. I went online, did some research. These are the things I did: did the "white screen of death" procedure. plugged the phone in and restored it. And I took off the film on the LCD. If you could please help, that would be much appreciated.
