Introduction

The guide will help take apart the Nintendo 3DS XL to uncover the motherboard, then identify the IR Board in order to be replaced.

Image 1/2: The screws have locking washers that prevent the screws from falling off of the back cover. Leave these locking washers on the screws, it is not necessary to remove the washers for this repair guide.

  • Unscrew the two 4.2 mm screws that are located at the top of the cover.

  • The screws have locking washers that prevent the screws from falling off of the back cover. Leave these locking washers on the screws, it is not necessary to remove the washers for this repair guide.

Note: If your top or bottom screen was working before disassembly and doesn't work after reassembly, then it's likely that the connector is loose or dirty or damaged or not clipped or PLACED UPSIDE-DOWN. I had this issue with my Super3DS XL(2015) and it turns out that the reason why my top screen wasn't working after put together, was because I had the top LCD connector upside-down. After I correctly put the connector in, It worked again!

  • Hold the device so that the cover is facing up.

  • Using a plastic opening tool, pry off the cover starting at the top right corner.

    • Hold the edge of the cover to ensure it does not reattach.

    • Look for the small section below the stylus compartment. Pry off the cover at that point if it is still attached.

  • Take off the cover of the device and set aside.

Note that on the lower side (opposite to the hinges), there are small hooking tabs. These require you to lift the top (screw side) off towards you, then the lower area.

  • Using tweezers pull out the rubber bumpers that are located at the top of the device on either side of the game cartridge compartment.

I found that the rubber bumps don't move easily, you'll likely have to use a lot of upward force to move them.

I torn one of the bumpers because I used a needle instead.

You do have a pry a bit. I tore one a little but not that big of a deal.

Christopher - Reply

I think the ease of this step would be subject to the age and condition of the 3DS. Mine came out with minimal leverage using my nails.

try twisting upward

I used a super tiny metal screwdriver to push the bumper against one side and then used the screwdriver to push it up and out

S Maduras - Reply

I tried tweezers but they were scraping against the plastic and I didn't want to leave any marks. Ended up using a tiny flat screwdriver to get them out like S Maduras said. Once I got them out I noticed there was a tiny bit of glue on the bottom holding them in place.

  • Remove the six 6.2 mm screws using a Phillips #00 screwdriver

#000 ifixit philips screwdriver does not fit the 6.2mm screws. Whats the deal?

sevenethshinobi - Reply

I have a 000 Phillips from tekton and it worked just fine.

Megan -

I stripped a good #000 screwdriver, and found that EVERY screw actually fit perfect and snug with a #00 screwdriver. Zero damage to the screws or the screwdriver with the #00.

Vannicke Trabeitt - Reply

Don't buy the #000 screwdriver from this site! It's poorly made and strips the screws. I had to drill the screws out and replace them, it was very tricky and nearly broke my DS. Get a screwdriver from an electronics store.

sharga - Reply

I bought and used the #00 screwdriver, and it worked perfectly for this.

I had also bought the #000, but I never needed it during the entire operation.

jconnell85 - Reply

All 6 screws are exactly the same so you don't have to worry about mixing them up.

Christopher - Reply

One of the screws in my 3ds XL seems to have its '+' engraving worn off, i can't seem to unscrew it, though the other 5 unscrewed properly. What should I do?

J000 works better here.

Make sure that you have removed your SD card, otherwise that'll keep you from completing this step.

The IR board is facing the wrong way.

Jordan - Reply

Thank you so much for pointing that out, it was keeping my system from starting up and I thought I blew it!

Ryan Hescock -

Yup, that is definitely an upside-down IR board, and will result in a silent post error. It was driving me crazy trying to figure out why the system wouldn't start up.

alexmouravskiy -

That's it!! Thanks so much!! I've tinkered around about one month and couldn't get this thing to work...all because I've followed the guide here and looked the picture up twice so I don't put the IR-Board in the wrong way...

chfreydank -

Hehe. That would explain why it was not working ;-)

boma40 - Reply

Thank you guys so much! I followed everything faithfully and it was DOA on startup. (Black screens, blue light). The IR board was backwards. These pictures need to be fixed. As-is, it shows a broken 3DS.

This IR is bad side, diode IR must be UP

Image 1/2: Do not use excessive force with the plastic opening tool. There is a ribbon attaching the circle pad joystick to the motherboard that will remain attached. Image 2/2: There is a loose washer located in between the circle pad joystick and the circle pad. Use caution and do not lose this piece.
  • Using a plastic opening tool pop off the circle pad joystick.

I found it easy to put my finger ontop of the board and apply a little pressure. When i popped off the board, my finger stopped it flying off.

  • Using the flat head side of the spudger carefully lift up the retaining flap that attaches the circle pad ribbon to the motherboard.

  • Remove the ribbon and circle pad joystick.

The 'flat head' holds it in place when down, and you can reattach your ribbon cable when it's up, it only needs to be partway in so when you close the flat head, if your joystick board can't move easily in place then you've done it right, it it's too loose, try again to work the ribbon cable under.

jconnell85 - Reply

The ribbon goes into the left side of the "flat head" right? Not the end that clamps down on the right? I'm having a !&&* of a time sliding the end of the ribbon into the little space between the flat head when it's up and the side of the terminal.

Sedroc Djeddi -

For those of you like me, who got stuck after the last step.

To understand how to actually remove the circle pad, continue with these steps at 21.

Nintendo 3DS Circle Pad Replacement

Hope it helps those after me. I almost ripped some cabling inside thinking I had to take out the motherboard.. luckily I didn't.

monk333y - Reply

Just as what monk333y said, follow the Original 3DS steps. They are identical and you don't have to remove anymore big parts. The only annoying part is taking out the circle pad.

luxusmirajane - Reply

I broke the retaining clip. It is not very strong and I used a bit too much force i think in opening the clip or pushing it back down. Thinking of using hot glue or something else to keep the circle pad ribbon in place.

Lawrence - Reply

How do you re attach the ribbons? do the just snap right into the motherboard?

petraogan - Reply

thank you monk333y, the author of this guide needs to correct a couple of things and how hard would it be for her to add steps 21 onward from the other guide?

S Maduras - Reply

step 11, if you're just replacing the button, you don't need to disconnect the circle pad ribbon from the motherboard.

S Maduras - Reply

During re-assemblhy, note that the peg between the joystick mechanism and the circle pad is rectangular, and must fit into the matching rectangular socket on the circle pad.

Image 1/2: Locate the IR board located on the upper right side of the motherboard. Image 2/2: The IR board is installed ''upside-down'' in these photos by mistake. Installing it this way will result in your DS failing to start. Note the orientation of your IR board before you remove it, and reinstall it the same way.
  • Position the device such that the game cartridge slot is located at the top.

  • Locate the IR board located on the upper right side of the motherboard.

  • Remove the IR board with a plastic opening tool by inserting the tool below the IR board and gently prying up.

The IR board appears to be upside down in this photo.

ealaney - Reply

One assumes they forgot to take the photo before removal and quickly put it back on upside down (accidentally) for the purposes of taking the photo.

Retro Gaming Repair -

Removing the IR board is actually a completely unnecessary step. It's absolutely fine to leave the IR board attached to the motherboard, it's then one less loose piece to go missing ;)

Retro Gaming Repair - Reply

The reason they remove these "easily loosable" pieces is because there's an order to put the board back together or the 3DS won't turn on. This is for replacing the motherboard, which most of the time you will buy and it won't come with the microphone, volume or IR board. Use your head kiddo. If it's so easy to loose these pieces, you should keep better track of them. We might as well just not take out any screws as well because those are very easy to loose

Miles Holiman -

You should add this note to the other uses of this picture; I accidentally knocked that chip off and reinstalled it upside down. I was referencing the photos for replacing the joystick.

Infernal Dalek - Reply

You skipped removing the microphopne.

In my 3DXL, there was no IR board: the parts were installed directly on the motherboard.

This guide was really helpful, I had to teardown my 3DS to remove a rice crispy that was stuck in the SD card reader, I don't know how it got there, I wasn't even eating cereals

was removing the analog stick really necessary?
