Introdução

The motherboard should only be replaced as a last resort. Be careful removing it!

  1. Ensure your device is powered off before proceeding. Failure to do so may result in electrical shock or damage to the device.

  8. To separate the cover, carefully lift it up and away from the hinges (in order to clear the headphone port), then pivot it towards the hinges to expose the circuit boards. Don't fully remove the cover yet, or you may damage the delicate ribbon cable that still connects it to the motherboard.

    • Use a pair of tweezers to disconnect the single ribbon connector.

    • Don't do what we did -- be very careful not to pull on the red cable.

  14. Using tweezers, gently pull the five marked ribbons out of the ZIF connectors along the sides of the motherboard. Note that these ZIF connectors are held in place by friction and do not have locks -- lifting the flaps on these connectors will break them! 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.

  16. 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.

Could someone point out where the fuses in the motherboard are hidden?

With some digging, I managed to find this on the GBAtemp forums , which host a community of 3DS modders:

Seems like no one's quite sure, but it could be a start. Unfortunately, the N3DS components are largely small black boxes with no labeling.

If you have a multimeter, it might help to test some of these mystery boxes.

Question: Seeing as how you pulled the red cable in the photos, how was that fixed? Asking for a friend.

We...never fixed that actually, as we didn't have the tools for it and the device had been loaned to us specifically for tearing down.

I don't know if iFixit themselves ever did anything with it, but I would imagine soldering the frayed end of the cable back onto the plug would work. (Here's a guide on that: http://www.instructables.com/id/Solderin... )
