    • With the hinge free to move, the iMac will be unbalanced and hard to work on. Place an iMac service wedge, in the stand to stabilize the iMac.

    • 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 side 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 the gap, cutting the foam adhesive in between the frame and display.

    • Be sure to always push with the cutting wheel forward. 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.

    • Gently twist the plastic card sideways to create a gap between the display and frame.

    • Move slowly and be careful not to stress the display glass too much—you only need to make a gap of about 1/4".

    • Gently twist the card upward, slightly increasing the space between the display and frame.

    • As with the other side, twist slowly to allow the adhesive time to separate, and be careful not to over-stress the display glass.

  16. iMac Intel 21.5" Retina 4K Display 2019 Left Speaker Replacement: 16 단계, 이미지 1/3 iMac Intel 21.5" Retina 4K Display 2019 Left Speaker Replacement: 16 단계, 이미지 2/3 iMac Intel 21.5" Retina 4K Display 2019 Left Speaker Replacement: 16 단계, 이미지 3/3
    • Slide the plastic card toward the center.

    • Stop sliding just before the iSight camera to avoid damaging the camera.

    • 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.

    • Continuing to support the display with one hand, flip up the metal retaining bracket on the display data cable.

    • Carefully pull the display data cable from its socket on the logic board.

    • Be sure to pull the display data cable connector straight out of its socket, keeping it parallel to the motherboard, to avoid damaging it.

    • 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.

    • 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.
