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 or six 13mm and two 25mm T8 Torx

Four 25 mm T8 Torx or two 25mm (outer) and two 35mm (inner) 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.

Disconnect the LCD temperature sensor by pulling the connector straight 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 display data cable to the logic board.
