    • Lift the display up to a near-vertical position.

    • At this point there is still a strip of adhesive along the bottom of the display that will hold the display to the frame like a hinge. You can loosen this adhesive by working the display up and down a few times.

    • Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply (boxed in red).

    • Grasp the small tab at the end of one of the bottom edge display adhesive strips and pull the adhesive toward the top of the iMac to remove it.

    • Repeat this step with the other adhesive strip and remove it.

    • If either adhesive strip breaks before it's removed, use a plastic card to slice through the remaining adhesive.

    • Lift the display up from the frame and remove it from the iMac.

    • It may be necessary to slowly lift from one side to peel against the remaining adhesive.

    • Be very careful handling the display—it's big, heavy, and made of glass.

    • After the adhesive is cut, it cannot be used to re-seal the display in place. Follow this guide to replace the adhesive strips that secure the display to the rear enclosure.
