analog stick, and other small parts.

This picture shows the parts of the bottom screen assembly. You'll

need something like a flat x-acto blade to separate the three parts

and replace whatever is broken.

1. This is the actual 3DS bottom LCD screen. If your new replacement

screen doesn't have insulation on the back, use some black electrical

tape. If it's allowed to touch the motherboard without insulation the

microfuses will blow and the 3DS will not turn on.

2. This is the touch panel / screen. It's attached to the LCD by a

thin adhesive strip. If you're replacing the touch panel you'll need

to reuse the adhesive strip.

3. This is a screen border that's glued to the touch screen. Can be

peeled off and reused on your new touch screen.

Reassembly is the reverse of removal.
