The motherboard is the central control circuitry of the Nook HD and is directly connected to many of the other internal components. While repairing a broken motherboard is beyond the scope of this guide, removing and replacing the motherboard is very doable.

Be sure the device is powered off. Clean the device to prevent any dirt and dust from entering into the device.
-
Use the plastic opening tool to gently pry the plastic screen frame away from the screen. Run the plastic opening tool along the interior edge of the screen until the screen frame is completely separated from the glass.
-
The screen frame is held onto the Nook by a set of tab that run around the outside of the frame. There may also be a line of rubber cement around the Nook under the screen frame. If your Nook has this, you will have to dig deep to separate the frame from the Nook.

what is the name of the connector in step 7?
This is by far the hardest step, if your Nook is like mine. There was a line of rubber cement around the Nook under the cover. If you have trouble removing the cover, do not be afraid to dig deep with your plastic prying tool. BTW, do not try this without the plastic prying tool!
