I replaced a broken digitizer on an ipad mini, one that requires no soldering. After replacing it (not set it in place yet) there is a set of lines going down the lcd screen, sometimes they change position based on what is on the screen. When you first boot it, the apple logo's color is slightly green, and the colors are slightly off. I was very gentle with the LCD, I don't think I bent it. I reseated the plug a few times, still having a problem. Any ideas on what to try next short of replacing the LCD?
