Step 8
¶
Remove the following screws securing the camera data cable and right speaker to the upper case:
One 9.9 mm partially threaded Phillips screw
One 9.6 mm threaded Phillips screw
One 4 mm Phillips screw
Slide the camera cable bracket out from under the subwoofer and remove it from the computer.
The iSight cable has an eyelet through which passes the left-most screw in these pictures.

Step 14
¶
Grab the upper case with your right hand and rotate it slightly toward the top of the display so the upper display bracket clears the edge of the upper case.
Rotate the display slightly away from the upper case.
Lift the display away from the upper case, minding any brackets or cables that may get caught.

Front Display Glass
¶
In the following steps, you will use a heat gun to soften the adhesive securing the outer black border around the underside of the front glass panel to the display. The area the adhesive is applied to is shown in red in the second picture.
With the heat gun set to low, start by heating the outer black border near the upper right corner of the glass panel.
Always aim the heat gun away from the soft rubber strip around the display glass. Heating the rubber will cause it to melt slightly, turning its finish from matte to glossy. Touching overheated rubber can cause it to permanently deform.
Due to the heat applied, it is normal for a layer of condensation to develop on the inside of the glass panel and/or the outside of the LCD. It can be removed with glass cleaner once the glass is separated from the display.

Step 16
¶
With the panel sufficiently heated, fasten a heavy-duty suction cup near the upper right corner of the display glass.
Don't fasten the suction cup on top of the rubber strip around the edge of the display glass.
To attach the suction cups we sell, first position the suction cup with the movable handle parallel to the face of the glass panel. While lightly holding the suction cup against the glass, raise the movable handle until it is parallel with the other handle.
Slowly and gently pull the corner of the display glass up off the display assembly.
If only the top edge of the glass lifts up (as seen in the third picture), repeat steps one and two until you can lift up the corner of the panel.

Edit
Step 17
¶
Gently lift the corner of the display glass enough to insert a spudger between it and the display assembly.
Use the flat end of a spudger to gently pry up the adhesive securing the front glass to the display.
Pry up the glass panel a few inches away from the upper right corner along the top and right edges of the display.

Edit
Step 18
¶
Use a heat gun to soften the adhesive under the black strip along the right side of the front glass panel.
Attach a suction cup along the right side of the front glass panel.
Pull up on the glass panel while you use the flat end of a spudger to separate it from the rest of the display assembly.
Continue working along the right edge of the front display glass until it is separated from the display.
It may be helpful to use a guitar pick or another thin plastic object to keep the upper right corner of the front glass panel from sticking back down to the display assembly.

Edit
Step 19
¶
Use your heat gun to soften the adhesive under the black strip along the top edge of the glass display panel.
Attach a suction cup near the top edge of the glass display panel and use it to pull the glass panel up off the display.
Work along the top edge of the glass panel, carefully using the flat end of a spudger to separate the adhesive if necessary.

Edit
Step 20
¶
Use a heat gun to soften the adhesive under the black strip near the upper left corner of the glass display panel.
Attach a suction cup near the upper left corner of the glass display panel.
Pull up on the suction cup and use the flat end of a spudger to carefully pry the glass display panel out of the display assembly.
Once the upper left corner has been separated from the display, it may be helpful to use a guitar pick or another thin plastic object to keep the glass from sticking back down to the display assembly.

Edit
Step 21
¶
Use a heat gun to soften the adhesive under the black strip along the left side of the front glass panel.
Attach a suction cup along the left side of the front glass panel.
Pull up on the glass panel while you use the flat end of a spudger to separate it from the rest of the display assembly.
Continue working along the left edge of the front display glass until it is separated from the display.

Edit
Step 22
¶
Now that the top, left, and right edges of the glass are free from the display, slowly lift the top edge of the glass panel and gently rotate it out of the display.
If necessary, use the flat end of a spudger to free the bottom edge of the glass display panel from the display assembly.
Before reassembling, be sure to clean both the inside of the glass display panel and the LCD as any dust or fingerprints trapped inside will be annoyingly visible when the machine is on. It is recommended to use a silicon roller and sticky sheets to clean well.

Step 24
¶
During the glass removal process, the camera cable may stick to the adhesive on the glass panel, disconnecting it from the camera board as the panel is lifted. If your camera cable is still connected to the camera board, skip this step.
To reconnect the cable, first use the tip of a spudger to remove the piece of foam tape over the camera cable ZIF socket.
Use the tip of a spudger to flip up the ZIF cable retainer on the camera cable socket.
Insert the camera cable into its socket on the camera board and use the tip of a spudger to snap down the ZIF cable retainer, locking the cable in place.
Reapply the piece of tape covering the camera cable socket.
