You just need a new LCD. I see the behavior a lot with various displays when they are damaged. below is a link to the part on the frame, just verify the model number I think there are some variations with the Z3 line. http://www.ebay.com/itm/Black-Touch-Screen-LCD-Digitizer-Display-Frame-For-Sony-Xperia-Z3-D6603-D6616-/401025112941?hash=item5d5ef59b6d:g:7IsAAOSwnH1WXrIv Here is a video of a tear down. You just need to gut the frame and then place it back into the new one. The back cover is a bit of a pain. Depending on how you pull it up you can sometimes reuse the adhesive that was on it. Just be sure not to pull crack it during removal.
