Kindle Fire HD 6 – Disassembling procedure – How to replace the Mother board


Kindle Fire HD 6:  DISASSEMBLING PROCEDURE 
Place the device face down on a clean cloth or another smooth surface. In the following steps, you will need to apply some force to your device. If your device is on a rough surface, you may scratch the screen. Insert the plastic opening tool between the device’s front and back panels. You might need to wiggle the tool up and down to wedge it in the gap. Maneuver the tool around the device until the back unclips from the front panel. Carefully separate the back panel from the rest of the device internals.
Unscrew the two 3.5mm T5 Torx Screws from the top of the camera.
Be careful not to damage the camera lens as you remove the camera. Gently pull the camera up and out of the device. As you pull, unclip the black and white connector with orange tape by popping it off at its base.
Unscrew the two 3.5mm T5 Torx screws at the base of the speaker.
Unclip the wire connected to the battery that runs up the side of the battery and clips into the motherboard by gently pulling it straight up.
Lift the speaker out of the device.
Using the flat side of the spudger, gently pry the battery off the adhesive. Be careful not to yank the battery you'll need to disconnect a connector before removing the battery completely. Remove the multi-colored connector that joins the battery and the motherboard by pulling it straight up. Lift the battery out of the device.
Use the tip of the spudger to disconnect the two zero insertion force connectors on the bottom and top of the motherboard.
The first connector is attached to an orange tape, and is located in the bottom-right corner of the motherboard. Remove this connector.
The second connector is long and thin, and is located at the top of the motherboard, a bit to the right of center. Remove this connector.
Disconnect the black and white connector at the very top-center of the motherboard by unclipping it using the flat side of the spudger.
Unscrew the ten 3.5mm T5 Torx screws around the edge of the motherboard.
Starting from the bottom, lift the motherboard out of the device. You will have to push the motherboard about two millimeters toward the top of the device to unhook the top edge.
