    • 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're using the iFixit cardboard service wedge, follow these assembly directions to put it together.

    • If you don't have an iMac service wedge, work very carefully—the display can easily fall out and break if the iMac moves unexpectedly.

  2. iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement, Remove the old adhesive: 2 단계, 이미지 1/2 iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement, Remove the old adhesive: 2 단계, 이미지 2/2
    • Before you install new adhesive strips, remove all of the old adhesive from the perimeter of the rear enclosure.

    • If you are re-using your existing display, you must also remove the old adhesive from the back of the display.

    • Peel off the old strips of adhesive using tweezers or your fingers. Start at the bottom and peel upward towards the top of the device.

    • After all the old adhesive is removed, carefully clean off the adhesive residue with high-concentration isopropyl alcohol (90% or greater) and a lint-free cloth. Wipe in one direction, not back and forth.

    • Don't skip this step, or your new adhesive strips may not bond properly, and the display may fall out of your iMac.

    • Your adhesive strips should have a microphone notch pre-cut in the strip labeled 4R.

    • If your 4R strip does not contain a notch, follow this guide instead.

    • Lay out the adhesives strips beforehand so you won't accidentally install a strip in the wrong place:

    • Strip 01 on the top left

    • Strip 02 on the top right

    • Strip 03 on the right vertical

    • Strip 4R on the bottom right, dark side facing up

    • Strip 4L on the bottom left, dark side facing up

    • Strip 05 on the left vertical

    • Start with strip 03, which goes on the right vertical side of the rear enclosure.

    • Before you peel off any backing, line the adhesive strip up along the frame of the iMac to get an idea of where it goes.

    • Grasp the blue tab and peel the short piece of backing off the back of the strip to expose a section of adhesive to attach to the enclosure.

  6. iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement, Apply the first adhesive strip: 6 단계, 이미지 1/2 iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement, Apply the first adhesive strip: 6 단계, 이미지 2/2
    • Insert the tip of a spudger into the hole at the end of the strip where you just removed one layer of backing. Insert the spudger from the side that still has a layer of white backing on it.

    • With the spudger still poking through the hole in the adhesive strip, push the spudger tip into the corresponding hole in the frame of the iMac.

    • Using the hole and spudger to anchor the position of the adhesive strip, line the strip up against the right edge, gently pulling up against the spudger to ensure the strip is taut, and stick it onto the frame.

    • Once you've aligned the bottom half of the adhesive strip, peel the longer piece of backing out from behind the strip.

    • If the bottom half isn't aligned properly, you can carefully peel it up and re-stick it before peeling off the lower backing strip. Be sure to use the spudger tip to anchor the top.

  9. iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement: 9 단계, 이미지 1/2 iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement: 9 단계, 이미지 2/2

    • Use your finger to smooth out the strip. Make sure it is neatly aligned with the right side of the frame and that it sits flat.

    • Do not peel off the front adhesive backing yet.

  11. iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement, Apply the remaining adhesive strips: 11 단계, 이미지 1/1
    • Work your way counter-clockwise around the perimeter of the iMac, adding three more adhesive strips in the same manner:

    • Strip 02 on the top right

    • Strip 01 on the top left

    • Strip 05 on the left vertical

  12. iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement, Install the bottom adhesives: 12 단계, 이미지 1/3 iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement, Install the bottom adhesives: 12 단계, 이미지 2/3 iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement, Install the bottom adhesives: 12 단계, 이미지 3/3
    • The next few steps will show you how to install the bottom right adhesive strip (strip 4R), which includes a notch that must be aligned with the microphone.

    • Read through this step and the next four steps before you attempt the procedure.

    • Grasp the red pull tab on strip 4R and pull to separate about 2 inches (5 cm) of white backing from the strip.

  13. iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement: 13 단계, 이미지 1/3 iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement: 13 단계, 이미지 2/3 iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement: 13 단계, 이미지 3/3
    • Fold the loose white backing to a right angle and pinch the crease with your fingers.

    • This exposes 2 inches of adhesive while folding the red tab out of the way.

  14. iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement: 14 단계, 이미지 1/3 iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement: 14 단계, 이미지 2/3 iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement: 14 단계, 이미지 3/3
    • The microphone hole is the center hole flanked by two larger holes.

    • Align the adhesive strip to the bottom edge by positioning the microphone notch over the microphone hole.

    • If your iMac does not have a microphone hole, align the right end of the strip such that the L-bend sits next to the right vertical adhesive. The L-bend should not overlap the right vertical adhesive.

    • The adhesive tears easily. Be careful not to pull on the strip with too much force.

    • Once you have aligned the strip, carefully set the left exposed edge onto the iMac to secure the alignment.

  15. iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement: 15 단계, 이미지 1/3 iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement: 15 단계, 이미지 2/3 iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement: 15 단계, 이미지 3/3

  16. iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement: 16 단계, 이미지 1/3 iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement: 16 단계, 이미지 2/3 iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement: 16 단계, 이미지 3/3
    • Run your finger from left to right along the length of the adhesive strip to ensure it is straight and unwrinkled, pressing down as you go to adhere the strip to the iMac.

  17. iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement: 17 단계, 이미지 1/3 iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement: 17 단계, 이미지 2/3 iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement: 17 단계, 이미지 3/3
    • Repeat the previous steps for the 4L adhesive strip, placing it along the bottom left edge of the iMac.

    • The 4L strip should be positioned such that the L-bend sits next to the left vertical adhesive. The L-bend should not overlap the left vertical adhesive.

    • Use painter's tape or masking tape to temporarily secure the bottom edge of the display to the iMac's enclosure.

    • The tape preserves the display's alignment, and allows you to safely swing the top edge of the display open to access the display cables.

    • Don't wrap the tape around the back of the iMac, or you may shatter the screen when you connect the cables.

  20. iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement, Test the display: 20 단계, 이미지 1/2 iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement, Test the display: 20 단계, 이미지 2/2

    • If you've already verified that your iMac is working correctly and are ready to seal it up, skip the next step.

    • Insert the display power cable into its socket on the logic board.

    • Set the display back on the iMac's rear enclosure.

    • At this time, plug in your iMac, power it on, and test your repair before moving on to actually sealing up the computer. Be sure to check for full functionality of any hardware you removed or disconnected.

    • When you are finished, shut the iMac down and unplug the power cord before you continue.

  23. iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement, Seal the iMac: 23 단계, 이미지 1/3 iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement, Seal the iMac: 23 단계, 이미지 2/3 iMac Intel 21.5" Retina 4K Display 2019 Adhesive Strips Replacement, Seal the iMac: 23 단계, 이미지 3/3

I found the service wedge not necessary. Of course, because I didn’t have one, I didn’t know what I was missing, either.
