Fix a Nintendo DS Touch Screen

•Step 1
Remove any unlicensed screen protectors. These affect the sensitivity
of the screen.

•Step 2
Clean the screen with a damp soft cloth and wipe dry. Do this
especially if you were using an unlicensed screen protector, as they
can leave residue on the screen.

•Step 3
Check the edges of the touch screen for debris by holding the Nintendo
DS at an angle. Remove any debris with a soft-bristled toothbrush.
Press the screen gently with your thumb to separate it from the
housing and hold the system so the side with the debris is at the top,
letting gravity help with the cleaning. Do not let the hard part of
the toothbrush touch the screen, as this could damage it.

•Step 4
Remove any game from the Nintendo DS and turn it on. Press the "A"
button when prompted to touch the touch screen, accessing the settings
screen.

•Step 5
Tap the settings menu panel icon, which resembles a file cabinet, with
the stylus, or, if the icon does not respond to the stylus, use the
control pad to move the cursor over the icon and press the "A" button.

•Step 6
Four colored icons will appear. Use the stylus or control pad to open
the orange icon resembling crosshairs.

•Step 7
Tap the red square that appears on the screen with the stylus. Repeat
as the square moves around the screen.

•Step 8
Follow onscreen instructions to exit, and the system will shut down
automatically to save the new settings.

•Step 9
The screen might need expert repairs if the previous steps do not
solve the problem. Repair requests can be submitted online through
Nintendo customer service. The system's serial number will be needed
to determine repair options.

Replacing the Touch Screen
•Step 1
Unscrew the screws on the bottom of the Nintendo DS with a tri-wing
screwdriver. Use a Phillips screwdriver to remove the screw that holds
the battery in place.

•Step 2
Remove the two screws under the battery with the tri-wing screwdriver.
This allows the backing to be removed to reveal the motherboard.

•Step 3
Pull off the shoulder buttons at the corner of the motherboard, taking
care not to lose the springs underneath them. Unscrew the four screws
on the motherboard with the Phillips screwdriver.

•Step 4
Use your fingernails or a flathead screwdriver to loosen and pull back
the black ribbon on the bottom left corner of the motherboard. Gently
pull out the four black clips, two at a time, that connect the
motherboard to the front of the Nintendo DS, which will allow the
motherboard to be removed. Place the motherboard to the side, upside-
down.

•Step 5
Pull out the touch screen with your fingers and gently detach it from
its adhesive.

•Step 6
Peel the plastic cover off the new touch screen, making sure not to
touch anywhere but the edges. Line up the new screen on the base and
rub it to make it adhere.

•Step 7
Reassemble the Nintendo DS, following the above steps in reverse.
