Nintendo DS Lite Lower Screen Replacement

Place your device upside down and locate the battery compartment.

Find the Phillips head screw securing the battery cover in the bottom right hand corner of the device.

Slowly remove the battery cover with the iFixit opening tool.

Use the iFixit opening tool to carefully pry the battery out of the case.

After the old battery is removed replace it with a new battery facing the same direction as when the cover was opened.

Remove the following seven screws that secure the lower case to the DS Lite:

Three silver tri-point screws (5mm long)

One black tri-point screw (4mm)

Two gold Phillips screws (4mm)

One silver Phillips screw (3mm)

Do not remove the silver PH screw (3mm) in the battery compartment yet. It holds the main PCB in place.

On the front edge of the Nintendo DS between the headphone jack plug and volume controls remove the plastic insert (or cartridge) from the lower slot (Slot 2).

Flip the unit over so that it is facing right-side up.

Use a spudger to pry open the gap between the bottom case and the front panel. Work all the way around the case until the panel is free.

Avoid touching the L and R shoulder buttons, because they easily detach and are difficult to reassemble. Keep the bottom case flat against your workbench to help hold the shoulder buttons in place.

Carefully separate the two pieces by hand.

The two shoulder buttons are made up of three pieces -- the plastic button, a pin, and a spring. If they accidentally pop out while you are working, study the picture and make sure you put the spring in the correct position.

Remove the two screws holding the motherboard to the rest of the device using a Phillips #00 screwdriver.

Locate the small ribbon cable that connects the touch screen to the motherboard. Do not pull on this cable.

Gently lift the hinged black cover on the connector.

After lifting the black cover, the ribbon cable will disconnect easily.

With a plastic opening tool, gently begin to separate the motherboard from the rest of the device.

Flip the motherboard over so the touch screen is facing up.

Do not pull on the main ribbon cable.

Carefully lift the tiny hinged cover on the connector.

The ribbon cable will easily disconnect.

Remove the third ribbon cable the same way.

There is nothing else connecting the touch screen. Just pick up and set aside.
