Hi! I have a New 3DS XL and I recently repaired the top LCD by replacing it with the necessary OEM one. Now the LCD itself has its own issues, like a couple dead pixels and some color saturation. But my biggest concern here is that the 3d isnt working properly. With and without stable 3d on, the picture gives a 2d, very blurry image that worsens as the slider goes up, and stops when it’s low. What could be doing this?

@joeyw532 “the LCD itself has its own issues, like a couple dead pixels and some color saturation.” is a pretty good indication that your screen is defective. Replace it once more with a known-good part and then reevaluate.
