If your speakers have stopped working, this is the guide for you! It will show you how to replace your speaker with a new one.
Use a T-9 Torx screwdriver to unscrew the four screws on the back cover.
Using the spudger, gently pry apart the back case from the front case. It is easier to start on a side and work your way around the device.
Once the two covers are separated, use the tweezers, or even your fingers, to gently disconnect the two sets of wires that are connected to the motherboard from the back cover. You may have to wiggle the wires a little bit to get them to disconnect.
Take the spudger and pry out the speaker.
