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 first picture, we made one out of a bent paperclip. A pair of angled tweezers can also work well.

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.

Raise and hold the display high enough to access the cables.

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.
