    Herramienta utilizada en este paso:
    iMac Intel 21.5" Cardboard Service Wedge
    $4.99

    • With the hinge free to move, the iMac will be unbalanced and hard to work on. Repairs are fast and easy with an iMac service wedge, but can be completed without one.

    • If you are using the iFixit cardboard service wedge, follow these assembly directions to put it together.

    • Before beginning any work on your iMac: Unplug the computer and press and hold the power button for ten seconds to discharge the power supply's capacitors.

    • Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply. Only handle the board by the edges.

    • Starting on the left of the display, near the power button, insert the iMac Opening Tool into the gap between the glass panel and the rear enclosure.

    • The hub on the iMac Opening Tool will keep you from pushing the wheel in too far. If using a different tool, insert no more than 3/8" into the display. Otherwise, you risk severing antenna cables and causing serious damage.

    • Use the tool like a pizza cutter—roll it along through the gap, and it will cut the foam adhesive through the center.

    • Be sure to always push with the handle behind the cutting wheel. If you pull, the wheel might get pulled out of the handle.

    • Run the tool up along the left side of the display.

    • While the opening tool cut most of the adhesive, the display will still be slightly adhered to the case. A plastic card will be necessary to free up the last of this adhesive.

    • Set the iMac face-up on a table.

    • Starting from the top right corner of the iMac, wedge a plastic card between the display and frame.

    • Be careful not to insert the plastic card more than 3/8", or you may damage internal components.

    • With both plastic cards inserted as shown near the corners, gently twist the cards sideways to increase the gap between display and case.

    • If there are any sections that seem to stick and won't separate, stop twisting and use one of the cards to cut the remaining adhesive.

    • Begin to lift the top of the display up from the frame.

    • Only lift the display a few inches—the display data and power cables are still connected to the logic board.

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