I replaced the top screen in my New 3DS XL, and now the screen works fine. The issue now is that when I enable 3D mode, the image just splits and is not correctable. I have run calibration but it doesn't do anything. I can definitely take it apart and re-examine the cables and all, but I'm curious what controls this? I'm pretty sure I need to check the camera, because that could be an issue, but what other cable/contact would control 3D mode?
