Step 2



• 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 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.

Step 3
• 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. Placing the glass flat, inside face down, on a fresh aluminum-foil surface is a good way to keep it clean.

Step 10
• 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.

Step 15
• Gently lift the CPU fan out of the rear case, minding any cables that may get caught.
• When reassembling your iMac, be sure the strip of foam near the top of the CPU fan does not get folded inward. It should rest on the surface of the CPU fan. We recommend using a credit card or another thin tool to hold the strip of foam clear of the CPU fan.
