Directions (All Models)

Power Off and Disassemble

NOTE: If available, use an anti-static mat and wear an anti-static wrist strap to minimize the risk of static electricity damage.

• Disassemble the device using a precision screwdriver set. Keep track of screws and components by organizing them in a way that makes reassembly easier.

Locate the Power Fuse

• The power fuse is a small rectangular component located near the power connector on the motherboard.

Desolder the Old Fuse

• Use the soldering iron to heat the solder joints of the old power fuse.
• Use a desoldering wick or pump to remove excess solder from the fuse's pads.
• Gently lift the old fuse away from the motherboard.

Replace with New Fuse

• Place the replacement fuse in the same position on the motherboard.
• Apply a small amount of solder to the pads, securing the new fuse in place.
• Be precise to avoid excessive heat, which could damage nearby components.

Reassemble the 3DS

• Carefully put the device back together, following the reverse order of disassembly.
• Ensure all components are correctly seated, and screws are tightened securely.

Test the 3DS

• Insert the battery and power on the 3DS.
• Confirm that the device powers up without issues. Check for any unusual behavior.
