Introduction

The speakers and 3D adjustment knob can all be found on the same ribbon cable. Replacing any of them requires first removing the entire speaker assembly.

  1. Nintendo 3DS Speaker Assembly Replacement, Back Cover: step 1, image 1 of 1
    • Unscrew the four Phillips #00 screws along the top of the back cover.

    • The screws are held in place by locking washers, and will not come out of the back cover.

    • The comments section is full of unlucky souls who will tell you that the screws here through step 4 will strip incredibly easily. Press down fairly hard, and go slow.

    • Remove the nine 6.3 mm black Phillips screws from the lower case.

    • These screws will strip very easily unless you use the correct size bit. Apply pressure to the screws while turning to avoid stripping them.

    • Remove the 2.4 mm silver Phillips screw above the game cartridge slot.

  5. Nintendo 3DS Speaker Assembly Replacement: step 5, image 1 of 3 Nintendo 3DS Speaker Assembly Replacement: step 5, image 2 of 3 Nintendo 3DS Speaker Assembly Replacement: step 5, image 3 of 3
    • Lift the bottom edge of the lower case off the rest of the 3DS.

    • There are still two ribbon cables connecting the mother board to the case, so be sure not to pull the lower case all the way off.

    • Use a plastic opening tool to pry the shoulder button ribbon cables off their sockets on the motherboard.

    • Remove the lower case from the device.

  6. Nintendo 3DS Speaker Assembly Replacement, Circle Pad Joystick: step 6, image 1 of 1

  13. Nintendo 3DS Speaker Assembly Replacement, Wi-Fi Board: step 13, image 1 of 2 Nintendo 3DS Speaker Assembly Replacement, Wi-Fi Board: step 13, image 2 of 2
    • Slide the flat end of a spudger under the corner of the Wi-Fi board, and lift it away from the motherboard.

    • The Wi-Fi antenna cable is still connected to the Wi-Fi board, so you cannot completely remove the Wi-Fi board yet.

  14. Nintendo 3DS Speaker Assembly Replacement: step 14, image 1 of 3 Nintendo 3DS Speaker Assembly Replacement: step 14, image 2 of 3 Nintendo 3DS Speaker Assembly Replacement: step 14, image 3 of 3

  16. Nintendo 3DS Speaker Assembly Replacement: step 16, image 1 of 3 Nintendo 3DS Speaker Assembly Replacement: step 16, image 2 of 3 Nintendo 3DS Speaker Assembly Replacement: step 16, image 3 of 3
    • Use the flat end of a spudger or your fingernail to flip up the retaining flap on the speaker assembly ribbon cable ZIF socket.

    • Be sure you are prying up on the hinged retaining flap, NOT the socket itself. Damaging the socket or cable will result in a 3DS that will blink its power LED when you press the power button - and do nothing else.

    • Disconnect the speaker assembly ribbon cable with a pair of tweezers.

  17. Nintendo 3DS Speaker Assembly Replacement: step 17, image 1 of 2 Nintendo 3DS Speaker Assembly Replacement: step 17, image 2 of 2
    • Use the flat end of a spudger or your fingernail to flip up the retaining flap on the camera ribbon cable ZIF socket.

    • Be sure you are prying up on the hinged retaining flap, not the socket itself.

    • When reassembling, note that the gold contacts face toward the motherboard (as opposed to the camera cable's gold contacts facing away).

  18. Nintendo 3DS Speaker Assembly Replacement: step 18, image 1 of 3 Nintendo 3DS Speaker Assembly Replacement: step 18, image 2 of 3 Nintendo 3DS Speaker Assembly Replacement: step 18, image 3 of 3
    • Remove seven Phillips screws securing the motherboard to the upper case:

    • Four 2.5 mm gold screws

    • Two 3.5 mm black screws

    • One 2.5 mm silver screw

    • When you remove this screw the volume slider can fall out.

    • Lift the side of the motherboard that sits along the bottom edge of the 3DS.

  19. Nintendo 3DS Speaker Assembly Replacement: step 19, image 1 of 3 Nintendo 3DS Speaker Assembly Replacement: step 19, image 2 of 3 Nintendo 3DS Speaker Assembly Replacement: step 19, image 3 of 3
    • Continue lifting the motherboard assembly and rotate it until it is resting next to the rest of the device.

    • Use the flat end of a spudger or your fingernail to flip up the retaining flap on the LCD ribbon cable ZIF socket.

    • Be sure you are prying up on the hinged retaining flap, not the socket itself.

  20. Nintendo 3DS Speaker Assembly Replacement: step 20, image 1 of 1
    • Remove the motherboard assembly from the rest of the device.

  21. Nintendo 3DS Speaker Assembly Replacement, Upper Display Front Panel: step 21, image 1 of 1
    • Before continuing with disassembly, use a pair of tweezers to remove the clear plastic diffuser for the wireless notification LED. The small piece is likely to fall out on its own, and may be difficult to find if it lands on the floor.

  22. Nintendo 3DS Speaker Assembly Replacement: step 22, image 1 of 2 Nintendo 3DS Speaker Assembly Replacement: step 22, image 2 of 2
    • De-route the Wi-Fi antenna cable from the bottom of the upper case.

    • This step is not necessary if you are only replacing the front panel; however, the replacement of the upper screen, speakers, cameras, and Wi-Fi antenna require it.

  23. Nintendo 3DS Speaker Assembly Replacement: step 23, image 1 of 2 Nintendo 3DS Speaker Assembly Replacement: step 23, image 2 of 2
    • Heat the edges of the upper display front panel with a hair dryer or heat gun to soften the adhesive holding it to the display bezel.

    • Begin prying the edges of the front panel off with a plastic opening tool.

    • If it is difficult to pry the front panel off, reheat the area you are working on with the heat gun, and then return to prying. Applying excessive force could crack the front panel.

  24. Nintendo 3DS Speaker Assembly Replacement: step 24, image 1 of 2 Nintendo 3DS Speaker Assembly Replacement: step 24, image 2 of 2
    • Continue prying the remaining sides of the front panel by sliding the plastic opening tool down each edge.

    • Too little heat will result in excessive bending/breaking of the front panel, and too much will melt and destroy the LCD underneath. Take your time.

  25. Nintendo 3DS Speaker Assembly Replacement: step 25, image 1 of 2 Nintendo 3DS Speaker Assembly Replacement: step 25, image 2 of 2
    • With all of the sides free, lift the upper display front panel off the display bezel.

  26. Nintendo 3DS Speaker Assembly Replacement, Rear Display Bezel: step 26, image 1 of 1
    • Remove the six 3.6 mm Phillips screws securing the rear display bezel to the front display bezel.

  27. Nintendo 3DS Speaker Assembly Replacement: step 27, image 1 of 2 Nintendo 3DS Speaker Assembly Replacement: step 27, image 2 of 2
    • Flip the device over so that the rear display bezel is on top and the hinge is on the side opposite from you.

    • Lift the edge of the rear display bezel closest to you and rotate it towards the hinge.

    • Continue to lift the rear display bezel off the rest of the device until it is free.

    • There are clips toward the bottom of the rear display bezel holding it in place. Use enough force to disengage the clips, but be careful not to break them.

  28. Nintendo 3DS Speaker Assembly Replacement, Upper Display Assembly: step 28, image 1 of 1
    • Remove the 3D adjustment switch from the front display bezel.

    • This step is not necessary for disassembly, but the switch is likely to fall out on its own. By removing it yourself, you reduce the chance of losing it.

  29. Nintendo 3DS Speaker Assembly Replacement: step 29, image 1 of 3 Nintendo 3DS Speaker Assembly Replacement: step 29, image 2 of 3 Nintendo 3DS Speaker Assembly Replacement: step 29, image 3 of 3
    • Insert a metal probe into the space above the ABXY buttons with the point touching the metal hinge.

    • Push the hinge towards the center of the upper case. This will require a fair amount of force.

    • Before and after images of the hinge location when looking at the back of the upper display are shown.

  30. Nintendo 3DS Speaker Assembly Replacement: step 30, image 1 of 3 Nintendo 3DS Speaker Assembly Replacement: step 30, image 2 of 3 Nintendo 3DS Speaker Assembly Replacement: step 30, image 3 of 3
    • Before proceeding, note how the 3 ribbon cables are oriented (what direction the gold contacts face) and layered together (which cable is on top of which). The cables are too short to reach if they are threaded through in any other orientation.

    • Slowly pull the upper display assembly away from the upper case.

    • Make sure that the various ribbon cables are being fed through the slit in the upper case.

    • Separate the upper display assembly from the upper case.

  31. Nintendo 3DS Speaker Assembly Replacement, Speaker Assembly: step 31, image 1 of 2 Nintendo 3DS Speaker Assembly Replacement, Speaker Assembly: step 31, image 2 of 2
    • Carefully feed the speaker assembly ribbon cable through the hole in the upper display bezel.

    • You must gently coil the ribbon cables (similar to an ice-cream cone) to allow them to fit - the cables are wider than the hole.

  32. Nintendo 3DS Speaker Assembly Replacement: step 32, image 1 of 1
    • Remove the 2.5 mm Phillips screw securing the right speaker board to the upper display bezel.

  33. Nintendo 3DS Speaker Assembly Replacement: step 33, image 1 of 3 Nintendo 3DS Speaker Assembly Replacement: step 33, image 2 of 3 Nintendo 3DS Speaker Assembly Replacement: step 33, image 3 of 3
    • Use the flat end of a spudger or your fingernail to flip up the retaining flaps on the parallax barrier ribbon cable ZIF sockets.

    • Be sure you are prying up on the hinged retaining flap, not the socket itself.

    • Use a pair of metal tweezers to disconnect the two ribbon cables.

  34. Nintendo 3DS Speaker Assembly Replacement: step 34, image 1 of 3 Nintendo 3DS Speaker Assembly Replacement: step 34, image 2 of 3 Nintendo 3DS Speaker Assembly Replacement: step 34, image 3 of 3
    • Use the flat end of a spudger to pry the left and right speakers out of their places in the upper display bezel.

    • Pry the camera status LED out of the upper display bezel with the tip of a spudger.

  35. Nintendo 3DS Speaker Assembly Replacement: step 35, image 1 of 1
    • Remove the speaker assembly from the rest of the display assembly.

Getting the new assembly ribbon cable through the hinge is excruciatingly tedious. I tore my cable when I tried fishing it through with a small hooked pry tool. Learn from my mistakes

Whatever you do, don’t accidentally hook the display ribbon cable into the slot for the speaker ribbon cable when reassembling. It holds it too firmly, and will rip easily. I now have to spend $15 on a new lcd ribbon cable.

For reassembly: when trying to put the ribbon cable through the hinge, you need to curve the end a bit to make it ‘flush’ with the hinge. I would also reccomend pulling the black hinge part out and lace the ribbon cable throught that way, then lace it through the hinge part, and then put the black hinge part back in the hinge socket.
