My wife cracked her screen. I replaced it with a black one I had on-hand. But, she really wanted the original white color. So, I ordered one and installed it. Now, the screen is jumpy. Check the video in my Dropbox link to see what it is doing. Is this a bad connection or a bad screen? https://www.dropbox.com/s/ma15rjdl60pjc7…
It’s usually a bad LCD or a broken ribbon cable. Test it with the old black screen to see if it has the same issue. Hope this helps! Good luck!
