Stick a suction cup near each of the two top corners of the glass panel.

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.

If your suction cups refuse to stick, try cleaning both the glass panel and the suction cup with a mild solvent.

Gently lift the glass panel perpendicular to the face of the LCD enough to clear the steel mounting pins attached along the underside of the top edge of the glass panel.

Pull the glass panel away from the lower edge of the iMac and carefully set it aside.

During reinstallation, be sure to meticulously clean the inside of the glass panel and the face of the LCD as any dust or fingerprints trapped inside will be annoyingly visible when the machine is turned on.

Remove the eight T10 Torx screws securing the LCD to the outer case.

Carefully lay the iMac stand-side down on a flat surface.

Due to tight tolerances, you will have to use a thin hooked tool to lift the display out of the outer case. As seen in the third picture, we made one out of a bent paperclip.

Use a thin hooked tool to lift one side of the top edge of the display by its steel outer frame.

After lifting the top edge of the display on one side, hold it out of the outer case while you use a hooked tool to lift the other side.

Do not lift the top edge of the display out of the outer case too far, as several short ribbon cables still connect the two components.

Use a pair of tweezers to pull the vertical sync ribbon cable out of its socket on the LED driver board near the top left corner of your iMac.

Rotate the display out of the outer case enough to disconnect the LED backlight power cable from the LED driver board.

Squeeze the two display data cable connector arms together to unlock it from its socket on the logic board.

Pull the display data cable connector away from its socket on the logic board.

Lift the display for enough clearance to disconnect the LCD thermal sensor cable connector from its socket on the logic board.

Carefully pull the display toward the top edge of your iMac and lift it out of the outer case.

The next few steps bring your hands close to the exposed face of the power supply. To avoid a high voltage shock from the many large capacitors attached to the board, do not touch the face of the power supply.

Disconnect the DC-In cable by using your index finger to depress the locking mechanism on the back of the connector while you pull the connector away from its socket on the power supply.

Once the locking mechanism has cleared the socket, pull the DC-In connector away from the power supply.

Disconnect the AC-In cable by depressing the locking mechanism while pulling the connector away from its socket.

Remove the following screws securing the power supply to the outer case:

• Two fine-thread shouldered T10 Torx
• One coarse-thread shouldered T10 Torx
• One short coarse-thread T10 Torx
