I. Disclaimer

First, you need to know if your DS has a fuse problem. It has been reported that DS Lite with blown fuse(s) starts with the Power LED on and immediately shutdown. Another symptom of blown fuses is when your DS will start and run normally but when the ac adapter is plugged in the charging LED doesn't come on and the battery doesn't charge. In this case it is F1 that has blown. In some cases it is because there is a short circuit in the upper screen, detectable by the top screen turning white partially. It is recommended that the top screen is replaced before the fuse is shorted. If you're not sure you have the same problem and still want to try bridging fuses, you can do so. I'm not responsible for any damage caused to your device. If you're not sure about what to do, stop it. However, you shouldn't get in trouble as you remove the battery and power plug during the manipulation.

II. What you need

  • Two DS Lite
  • A tri-wing screwdriver (to open the DS)

(A 1.4mm precision straight slot screwdriver can also be used but be careful)

  • Thin wire (to replace the fuse, should be QUITE THIN)

Even better, use the correct fuse for replacing...... see a video of repalcing the fuse below.

  • An iron solder (to solder the small wire replacing the fuse)

  • Wire solder (also used during solder)

III. Open the DS

  • Remove the battery cover
  • Remove the battery
  • Unscrew every tri-wing screws with the screwdriver

IV. Finding F1 & F2 fuses

To find the F1 and F2 fuses, take a look on the DS motherboards pictures below (there are several kinds) and locate them on your DS too.

These are DS Lite motherboards with different serials (USG-CPU-01 and USG-CPU-X3).

These pictures are from an old DS (serial NTR-CPU-01), in case you want to repair one.


V. Testing and bridging fuse(s)

As I don't know what kind of fuse are used in the DS and as users reported that using wire to bridge the fuse wasn't harmful, I'll explain you with this method. You should first check with a multimeter which fuse is blown, then bridge it. Most of the time, F2 fuse is the blown one.

      • Imortant, if you replace the fuse with a wire bridge and the DS has a fault again it will blow the entire motherboard not the fuse - they are there for protection and are VERY important, especially if you use a flashcart - REPLACE FUSES WITH FUSES!!!***

Bridging Fuse 1/2 (method 1)

Take a look at the pictures below.

Image:dsfuse2ei1.jpg

The red line represents the small wire. It has to touch both contacts. Now solder by doing two little points of wire solder (represented by the blue squares). An alternate method is to simply solder across the two terminals. Scratching any coating from the surface of the terminals helps insure connectivity.

Bridging Fuse 2 (method 2)

If it's too difficult to solder in top of the fuse, you can use this alternative method. But this is ONLY FOR FUSE 2

You only need to make a point between BAT+ and VDET.

After soldering the blown fuses, assemble your DS back and try to start it.

Your DS should work after that :).

Thanks to scdev.org members for information (bitblt for F2 pictures too).
