    • 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.

    • Continue along the top of the display.

    • You may want to run the tool back and forth through what you've already cut a few times, to ensure you get as much of the adhesive separated as possible.

    • Push the tool around the top right corner of the display.

    • Wheel the tool down along the right side of the display.

    • Finish pushing the opening tool to the bottom of the right side of the display.

    • At this point, you'll want to run the tool back around the entire display, to ensure you cut as much adhesive as possible.

    Plastic Cards
    $2.99
    구매
    • 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".

  12. iMac Intel 21.5" EMC 2638 Display Replacement: 12 단계, 이미지 1/3 iMac Intel 21.5" EMC 2638 Display Replacement: 12 단계, 이미지 2/3 iMac Intel 21.5" EMC 2638 Display Replacement: 12 단계, 이미지 3/3
    • Slide the card toward the center of the display to cut any of the remaining adhesive along the top right corner of the iMac.

    • Be sure to stop before the iSight camera, or you may damage it.

  13. iMac Intel 21.5" EMC 2638 Display Replacement: 13 단계, 이미지 1/2 iMac Intel 21.5" EMC 2638 Display Replacement: 13 단계, 이미지 2/2
    • Wedge the plastic card into the top right corner once again, and leave it there to prevent the adhesive from resticking.

  14. iMac Intel 21.5" EMC 2638 Display Replacement: 14 단계, 이미지 1/3 iMac Intel 21.5" EMC 2638 Display Replacement: 14 단계, 이미지 2/3 iMac Intel 21.5" EMC 2638 Display Replacement: 14 단계, 이미지 3/3
    • Insert a second plastic card into the gap between the display and frame near the top left corner of the iMac.

  15. iMac Intel 21.5" EMC 2638 Display Replacement: 15 단계, 이미지 1/2 iMac Intel 21.5" EMC 2638 Display Replacement: 15 단계, 이미지 2/2
    • 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" EMC 2638 Display Replacement: 16 단계, 이미지 1/3 iMac Intel 21.5" EMC 2638 Display Replacement: 16 단계, 이미지 2/3 iMac Intel 21.5" EMC 2638 Display Replacement: 16 단계, 이미지 3/3
    • Slide the plastic card toward the center, again stopping just before the iSight camera.

  17. iMac Intel 21.5" EMC 2638 Display Replacement: 17 단계, 이미지 1/2 iMac Intel 21.5" EMC 2638 Display Replacement: 17 단계, 이미지 2/2
    • Wedge the plastic card back into the top left corner.

  18. iMac Intel 21.5" EMC 2638 Display Replacement: 18 단계, 이미지 1/3 iMac Intel 21.5" EMC 2638 Display Replacement: 18 단계, 이미지 2/3 iMac Intel 21.5" EMC 2638 Display Replacement: 18 단계, 이미지 3/3
    • 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.

  19. iMac Intel 21.5" EMC 2638 Display Replacement, Display: 19 단계, 이미지 1/2 iMac Intel 21.5" EMC 2638 Display Replacement, Display: 19 단계, 이미지 2/2
    • While holding the display up with one hand, use the other hand to unplug the display power cable.

    • Lift the display up enough to have easy access to the connector, but not so much that you stretch the cables and stress their connections (about 8").

  20. iMac Intel 21.5" EMC 2638 Display Replacement: 20 단계, 이미지 1/3 iMac Intel 21.5" EMC 2638 Display Replacement: 20 단계, 이미지 2/3 iMac Intel 21.5" EMC 2638 Display Replacement: 20 단계, 이미지 3/3
    • Use the tip of a spudger to 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.

    • 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.

  22. iMac Intel 21.5" EMC 2638 Display Replacement: 22 단계, 이미지 1/2 iMac Intel 21.5" EMC 2638 Display Replacement: 22 단계, 이미지 2/2
    • If necessary, a plastic card can be used to cut any remaining sections of the bottom adhesive strip.

  23. iMac Intel 21.5" EMC 2638 Display Replacement: 23 단계, 이미지 1/3 iMac Intel 21.5" EMC 2638 Display Replacement: 23 단계, 이미지 2/3 iMac Intel 21.5" EMC 2638 Display Replacement: 23 단계, 이미지 3/3
    • 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.

Hi, where can I buy a replacement display for my iMac EMC 2742 (2742 is the same as 2638, I assume?)...Thanks so much!

Cameron - 답글

I put off replacing my hdd with an ssd on my late 2013 iMac because it looked a bit tricky. This guide and an iMac opening tool made the job really strait-forward. Just be gentle and patient and the screen comes off with very little bother. Thanks ifixit!

Used this and the adhesive guide to replace the cracked display on a relative’s 21.5 inch iMac. Thank you, iFixit! These guides and the toolkit I purchased from iFixit years ago have saved me roughly $200.00 vs. having a repair shop do it. I still have a 2008 24inch iMac up and running thanks to this website!

I used this guide and successfully replaced the stock HDD with a Crucial 1TB SDD MX500 and upgraded the RAM to 16GB, blew out all the internal dust and now it runs beautifully and didn’t have to buy an entirely new iMac.
