Loosen the single Phillips screw in the center of the access door.

This screw is captive in the access door.

Remove the access door from your iMac.

The glass panel is fixed onto the front bezel with fourteen magnets around its perimeter.

Stick two suction cups to opposing 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 such as Windex.

Gently pull the glass panel straight up off the iMac.

The glass panel has several positioning pins around its perimeter. To avoid shearing these pins off the glass panel, be sure to only pull straight up during removal.

Be meticulous about cleaning the LCD and the inside face of the glass panel before reinstallation, as any fingerprints or dust trapped inside will be annoyingly visible when the display is on.

Remove the following 12 screws securing the front bezel to the rear case:

• Eight 13 mm T8 Torx.
• Four 25 mm T8 Torx.

The front bezel is still attached to the iMac by the microphone cable.

Gently lift the front bezel from its top edge off the rear case. It helps to use your thumbs to push down very gently on the corners of the display.

Once the top edge of the front bezel has cleared the rear case, rotate the front bezel toward the stand and lift it off the rear case.

When reinstalling the front bezel, start at the lower edge and make sure it is flush with the rear case before lowering the top edge onto the iMac.

Disconnect the microphone cable connector, removing tape as necessary.

For the front bezel to sit properly, be sure to tuck the microphone cable and connector into the void next to the camera board.

Pull the LCD temperature sensor connector straight up out of its socket on the logic board.

If necessary, de-route the LCD temperature sensor cable from behind the logic board.

Remove the two 5.3 mm T6 Torx screws securing the data display cable to the logic board.

Use the attached black tab to pull the data display cable connector away from the logic board.

Remove the eight 12 mm T8 Torx screws securing the display panel to the rear case.

Lift the display panel from its left edge and rotate it toward the right edge of the iMac.

With the display panel still lifted, disconnect the four inverter cables.

During reinstallation, place the four inverter cable connectors in voids between components attached to the rear panel so the display panel will sit flush.

During reassembly, the order of the inverter cables is interchangeable within each socket.

If you are replacing a hard drive and have an extra set of hands, it is possible to reach in and remove the drive without disconnecting anything but the LCD temp and display connector in the previous step with the LCD in its propped position.

If necessary, remove the pieces of tape securing the hard drive/optical drive thermal sensor cables to your iMac.

Disconnect the optical drive thermal sensor connector from the logic board by pulling its connector toward the top of your iMac.

When removing this connector, it is helpful use your thumbnails to push the ears on either side of the connector toward the top of your iMac.

Remove the two fine-thread 7 mm T10 Torx screws securing the optical drive to the rear case.

Lift the free end of the optical drive slightly out of the rear case.

Remove the two 3.5 mm T6 Torx screws securing the optical drive connector to the optical drive.

Insert the flat end of a spudger between the optical drive connector and the body of the optical drive.

Twist the spudger to separate the connector from the optical drive.

It may be necessary to work from alternating sides of the connector until it is disconnected.

Lift the optical drive out of the rear case and pull it away from the side of the rear case to release the strip of EMI tape attached to its surface.

The optical drive thermal sensor is still attached to the underside of the optical drive.

Remove the two 13 mm T10 Torx screws securing the inverter to the rear case.

Pull the inverter away from the chassis and lift it slightly out of the rear case.

Disconnect the inverter cable by simultaneously squeezing the locking mechanism and pulling the connector away from its socket.

Lift the metal case off the inverter.
