I have an iPad mini 4 that needed a dock replacement and battery. I changed them out. When putting the screen back together there is now vertical lines on the screen or sometimes like a white tent over the screen. Prior to the repair the screen was perfect. I don’t think it would be the screen because I carefully removed it like I usually do and disconnect the battery and then everything else. I’ve done tons of screen replacements but just stumped on the iPad mini 4 because this is the second time it’s happened. The other iPad mini 4 the only thing I replaced was the wifi antenna but came out to the same issue.. I noticed on one of your other videos on older models the iPads had magnets and were important have those magnets back in place where they belong but in my case the iPad mini 4 don’t have magnets. Would be able to guide me through or hint me specific spots to check for please. Btw the dock charges perfect and new battery is good.I’ve already ordered two replacements screens to narrow down the problem.
