Replaced battery and waves noticeable on background
I replaced my iPad Air 2 battery and was able to take it apart and replace it using a kit and a heat gun. Unfortunately after turning it on everything works except that there is waves in the background which is extremely annoying when reading. Watching movies and YouTube you can’t see see it really. It usually shows up on lighter backgrounds. Any ideas? At this point I wish I never opened the thing up in the first place. See photo.
