3DS Bottom Screen Bright and Blue Filter

Some buttons on my 3ds weren’t totally responsive, so i took it apart to clean out. Good news is the buttons work fine. Bad news is that I now have a very bright blue filter on the bottom screen. This feels like the opposite of a bluelight filter and us super bright even after fiddling with brightness and power saving settings. Everything works fine but the bottoms screen being so bright and off-color is a bit disorienting. I have also tried opening it back up and blowing out possible dust from connectors with compressed air without success. Any help is greatly appreciated. (it won’t let me include pictures, sorry)
