DISASSEMBLING PROCEDURE 
Unscrew the Phillips screw securing the battery cover to the lower case. The screw remains captive to the battery cover. Pry the battery cover upward with a spudger or fingernail, and lift out of the lower case.
Wedge the edge of a spudger in between the side of the battery and the lower case housing and pry upward to dislodge the battery. Remove the battery from the DS Lite.
Use the tip of a spudger to pry both rubber feet off the DS Lite.
Remove the following screws securing the lower case to the body of the DS Lite:
Two 4.3 mm gold Phillips screws
One 3.9 mm black Tri-Wing screw
One 3.3 mm silver Phillips screw Three 5.5 mm silver Tri-Wing screws
Insert the edge of a spudger in between the lower and upper case near the top right corner of the DS Lite. Carefully run the spudger along the right edge of the DS Lite, creating an opening in the process. Continue running the spudger along the backside of the DS Lite until the majority of the lower case has been separated from the upper case.
Lift the lower case away from the rest of the DS Lite.
Lift both trigger buttons out of the DS Lite. The trigger buttons are held in very loosely by small metal pegs and springs. Don't lose track of these pieces. The second picture shows the correct configuration of the trigger assembly for reassembly purposes.
Use the flat edge of a spudger to pry the Wi-Fi antenna connector straight up from its socket on the Wi-Fi board.
Use the flat edge of a spudger to pry the Wi-Fi board connector straight up from its socket on the motherboard.Use the flat edge of a spudger to separate the right edge of the Wi-Fi board from the motherboard. The Wi-Fi board is secured to the motherboard with a layer of adhesive. Remove the Wi-Fi board from the DS Lite.
Use the flat edge of a spudger to pry the microphone connector straight up from its socket on the motherboard.
In the following steps you must pull the antenna cable between the DS Lite game cartridge reader and motherboard. Pull slowly and stop when you feel resistance to avoid damaging the cable or motherboard.
Position the antenna cable with its connector facing up and away from the motherboard using a spudger to hold it down lightly in the gap between chips on the motherboard. Slowly and carefully pull the antenna cable until the cable connector is under the DS Lite game cartridge reader.
Continue pulling the cable until the cable connector comes out from under the game cartridge reader on the right side.
When reassembling and attempting to feed the antenna cable back under the game cartridge reader, the cable may kink or become difficult to feed through. If so, try feeding a piece of thread through first; then, tie the thread to one end of the cable connector and pull it through, guiding it past any obstructions.
Use your fingernail or the edge of a spudger to carefully flip up the touchscreen ribbon cable retaining flap. Make sure you are flipping up the retaining flap, not the socket itself. Use the tip of a spudger to pull the touchscreen ribbon cable straight out of its socket.
Remove the two 3.4 mm Phillips screws securing the motherboard to the upper case.
Open the display enough to use your finger to push the front edge of the motherboard up and away from the upper case. Do not try to remove the motherboard, as it is still connected to the upper display via the upper LCD ribbon cable.
Use your fingernail or the flat edge of a spudger to carefully flip up the upper LCD ribbon cable retaining flap.
Make sure you are flipping up the retaining flap, not the socket itself. Pull the motherboard away from the DS Lite to separate the upper LCD ribbon cable from its socket on the motherboard.
Remove the motherboard from the DS Lite. Now you may open the retaining flap for the lower LCD screen in the same way and separate the lower LCD screen from the motherboard.
Repairing a Nintendo DS that is not charging
The EM10 charging filter is located next to the power connector on the motherboard. If the filter is missing or obviously broken, move on to STEP 18 Use a multimeter to test the EM10 filter - measure the resistance between each of the yellow solder pads, and then between each of the cyan solder pads. If everything is OK you should have close to 0 Ohms between each set of pads. You should NOT have any connection between the cyan pads and yellow pads. If the filter fails either test it needs to be replaced.
