Disassembling Nintendo DS Lite Lower Screen

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.

Place the battery cover on the top and gently screw in the phillips head screw to firmly secure the battery.

After this step you will have successfully relpaced your Nintendo DS battery.

Remove the following 7 screws securing the lower case to the DS Lite:

• 3 silver tri-wing screws (5mm long)
• 1 black tri-wing screw (4mm)
• 2 gold Phillips screws (4mm)
• 1 silver Phillips screw (3mm)

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

Remove the plastic insert (or cartridge) from the lower slot (Slot 2).

Flip the unit over.

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 pop off easily and are difficult to reassemble. Keeping the bottom case against your workbench will help hold them 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.

When reassembling the cover, make sure that the power switch cover on the bottom case is in the off (down) position. Otherwise, the power switch cover can break the very fragile power switch upon reassembly.

After taking the back panel off, locate and unscrew the two screws holding the logic board to the rest of the device.

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

Gently lift the hinged black cover on the connector.

The hinges are near where the ribbon is inserted.

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

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

Flip logic board over so 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.
