Introduction
This is a guide to help walk you through how to replace the lower LCD and the Touchscreen Digitizer.
What you need
-
-
Place the 3DS upside down. Remove the game card, headphones, charging cable, stylus, or anything else that may be connected to the device.
-
-
-
Using a JIS #00 screwdriver, remove the six 6mm screws around the edges of the secondary cover.
-
-
-
-
Use tweezers to flip up the small, hinged locking flap in order to unlock the ZIF connector securing the Circle Pad ribbon.
-
Slide the ribbon out of the ZIF connector.
-
-
-
Using tweezers, gently pull the four marked ribbons out of the ZIF connectors along the sides of the motherboard.
-
Three of the ribbon connectors have plastic clamping flaps that cover the ribbon to prevent slippage. Use the tweezers to flip them up before ribbon removal.
-
This one ribbon connector may also have a plastic clamping flap, but it's not like the others, rather it's similar to the one used for the Circle Pad. Gently flip up the flap on the side opposite the ribbon cable to remove the cable.
-
-
-
Carefully pivot the motherboard 90 degrees toward the hinges to reveal two more ZIF connectors on the underside of the motherboard.
-
Both have latches that must be flipped up. The left, longer latch is black; the right, shorter one is white. Flip up the flaps, slide the ribbons out and remove the motherboard.
-
-
-
Using a JIS #000 screwdriver, remove the three screws.
-
Next, remove the game card reader by lifting it up.
-
-
-
The part marked in red is the support bracket for the NFC antenna. You must remove this before proceeding with the LCD/digitizer assembly.
-
Release the plastic support clips of the NFC antenna using a thin tool on the top and bottom. Then, detach it.
-
-
-
Slide a flat tool between the LCD/digitizer's black support and the console casing, then lift it gently. Next, slide an opening pick underneath to hold it.
-
Next, you can either lift the whole thing from underneath by pushing it up or continue to make your way around, unclipping the whole assembly and extracting it.
-
-
-
Slide a thin pry tool between the LCD and the black casing of the whole display, then lift it gently. The LCD comes out without forcing it.
-
-
-
Warm the edges of the touchscreen to peel it off more easily, then push it gently from underneath with your fingers to remove it.
-

I followed this guide to the letter last night on my hyrule gold new 3ds XL (from hence forth I will refer to this unit as my “old n3dsXL”) before attempting the same repair on my new unit. It worked fine on my old n3dsXL. So I went ahead with doing the same repair on my new unit.
Well it went fine till I tried to turn it on. The blue light comes on then after a few seconds there’s a “pop” sound and the unit turns back off. Can anyone tell me what just happened here?
Also tried putting the original touch screen back in the new unit and it still does the same pop sound and shuts off
You might need to reseat the cables i had this issue on my old ds lite and my old n3ds all i had to do was that and it fixed it for me also if that doesn’t work get a cotton swab and dip it in rubbing alcohol and clean the end of the ribbon cables then re insert them.
Same thing happened to me my first time—brief blue light but would not power on. Tore it down and re-connected all the cables more carefully the second time. That fixed it.

I just disassembled my new 3ds xl to clean my lower screen and touch sensor following this guide, it went smoothly but now everything works except the touch sensor, why??
I have done this successfully three times now—thank you for the excellent guide. Newcomers should know there is one ERROR and one OMISSION in the procedure. (1) ERROR - In Step 13, the topmost ZIF connector marked in red *does* have a clamp, unlike the other four. If you attempt to pull the connector loose without opening the clamp you will break it—see the frustrated comments to Step 13 for examples. (2) OMISSION - At Step 16, before removing the cartridge drive you must unplug the connector at the top of the component. This is shown as unplugged in the photo, but the step is missing from the written instructions. The clamp on this plug loosens on the *opposite* side from where the cable is inserted, unlike the other clamps in the guide.
