Removing the display requires cutting through the adhesive around the perimeter of the screen. After the adhesive is cut, it cannot be used to re-seal the display. You'll need to apply a new set of adhesive strips to ensure a proper seal.

    • With the hinge free to move, the iMac will be unbalanced and hard to work on. Repairs can be completed as shown, but are faster and easier with an iMac service wedge.

    • If you are not using an iMac service wedge, be very careful when installing and working behind the display—it can easily fall out and break if the iMac moves unexpectedly.

    2 Kitchen Paper Towel Rolls do the same job as the Wedge just fine .. :)

  1. Before you start placing strips, remove all of the old adhesive around the perimeter of the rear enclosure.
    • Before you start placing strips, remove all of the old adhesive around 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.

    • Use a pair of tweezers to grasp and peel up the edge of each adhesive strip.

      • Repeat this process as necessary to remove all of the old adhesive.

      • If necessary, use a spudger to scrape up the remaining adhesive, then peel with your fingers.

    it's not noted here, but if you are just replacing an internal part and intend to use the same display, you must also remove the adhesive from the display

    Noted and added to the guide! Thanks :)

    Depending on what adhesive you are removing, I find that using something like Goo Gone Goop adhesive remover is very helpful.

    If it is the original foam based adhesive, then that can usually be taken off without the adhesive remover, but with these after market glue strips, the adhesive remover is best.

    Spudger and tweezers couldn’t seem to get enough under the strip to grab. I had to use a low-angle edge of an Xacto blade.

    • Start with the strip labeled 3 (or 03), which goes on the right vertical side of the rear enclosure.

    • Before peeling off any backing, line it up against the frame of the iMac to get an idea of where it goes.

    • Peel the short piece of backing off the back of the strip.

    Добавить комментарий

    • Insert the tip of a spudger into the hole at the end of the strip from the side that still has a backing on it.

    With more than a little manipulation, the strips had a tendency to stretch, so the holes at each end did not quite align.

    bstaud - Ответить

    I agree, line them up gently, don’t pull on the strips too hard or they will stretch.

    fo4ever - Ответить

    • 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.

    Добавить комментарий

    • 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.

    The info comment makes no sense. If you have to "re-stick it" then you have already peeled off the lower backing strip. If "it" means the upper portion of the strip, the use of a pronoun instead of naming the part specifically is confusing.

    Mark - Ответить

    • Align the upper half of the strip with the right edge of the rear enclosure, and stick it down.

    • Use your finger to smooth Strip 3 along the right edge. 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.

    Добавить комментарий

    • Work your way around the perimeter of the iMac, adding three more adhesive strips in the same manner.

    • Working counter-clockwise from Strip 3, place:

      • Strip 2 on the top right

      • Strip 1 on the top left

      • Strip 5 on the left vertical

    Please update this pic with newer model 2017, where you can see the wholes for the mic!!! These must not be covered! I hope the set of tapes 4R considering this issue, otherwise the mic will not work, as I used to have it!

    • The two remaining strips (4L and 4R) do not have guide holes and are more difficult to place than the previous ones. Before sticking them down, we recommend first setting them in their respective places on the iMac to get comfortable with their placement.

    • Grasp the red film pull tab on the 4R adhesive strip and pull to remove the backing from the strip.

    • Align the strip on the bottom edge of the rear enclosure, directly to the right of the middle screw on that edge.

    • Run your finger 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.

    For some reason the adhesive strips for the bottom (4L and 4R) have the outer side as black whereas the others are white. A bit disorienting.

    bstaud - Ответить

    when i pull the red tab at least one of the bottom strips always has the wrong side peel off. Poor design.

    Charles Lindauer - Ответить

    Yes, all of the other strips go on without problem, but every strip kit I’ve ordered has the 4L and 4R strips reversed (like in the picture). And pulling the red tab usually doesn’t work at all. Why aren’t they just made like the rest of the strips?

    Brian Toth - Ответить

    • Repeat the previous step for the 4L adhesive strip, placing it along the left half of the bottom edge of the iMac.

    • Once you've applied all the adhesive strips, the iMac should look as shown in the photo.

    Unless my iMac was assembled incorrectly, the 4L and 4R strips are mislabeled and should be reversed . The right angles of the strips should be towards the outer bottom edges of the display. I have photos but not sure how to get them in here.

    The picture here doesn’t quite match the currently provided tape kit. You should see two sets of each number, not one number and a bit of blue tape.

    • Gently lay the display in place over the iMac, and align it carefully.

    It is important to wedge something between the unit and the base so it doesn't swivel down as you are replacing the front cover. An unopened 5 pound sack of flour works fine.

    • 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.

    1.Painter’s tape or masking tape (or low-residue duct tape, which I used) should be on the list of tools and materials.

    2. I made strap of tape for a side to prevent the display from hinging open too far.

    bstaud - Ответить

    Make sure the tape is put in place after you’ve got the screen in exactly the right spot! And no tape around the sides, the screen still needs to swing.

    • At this point it's a good idea to test your repair, in order to make sure your iMac works properly before you seal it back up. Follow the next three steps to temporarily reconnect the display cables and boot up your iMac prior to pulling the protective film off the adhesive strips.

      • If you've already verified that your iMac is working correctly and are ready to seal it up, skip to Step 17.

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

    • Use a pair of tweezers or your other hand to gently insert the display data cable connector into its socket on the logic board.

    • Be sure to press it straight into the socket, and insert it completely.

    • Secure the metal retaining bracket on the display data cable downwards towards the logic board.

    0. Put a loupe or magnifying glass on the list of tools and supplies.

    1. It would be good to show an enlarged picture of the data cable connector to see how it works.

    2. In my case, the metal retaining bracket did not hold the connector securely enough, so the connector kept popping out.

    • 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.

    Добавить комментарий

    • Verify that your iMac is turned off and unplugged from power before you continue.

    • After confirming that your iMac functions properly, disconnect the display cables and carefully lean the display forward.

    • Remove the film from the 4R strip by reaching in from above and pulling the tab straight up from the bottom edge of the display.

    i had to tip the display outward enough for the strip to peel off. Glad it had the tape hinge.

    bstaud - Ответить

    • Repeat the previous step for the 4L strip.

    • Reconnect the display power and data cables for the final time.

      • Remember to secure the metal retaining bracket on the display data cable.

    • Check the glass directly in front of the webcam for dust and other contaminants. If necessary, wipe it down with a microfiber cloth before you seal up the display.

    • Rest the display against the rear enclosure.

    • Remove the protective film from Strip 1 by pulling its tab straight up.

      • The film/liner may break if pulled too hard. Work carefully and make sure that there's no pressure on the display and that it doesn't pinch the strips.

    Pull them out slowly, cos you the coverstrips can rip easily resulting in having no adhesive in that area cos the strip is rendered unreachable… (happend to me twice) ..

    Stef999 - Ответить

    • Likewise, remove the protective film from the strip that was paired with Strip 1.

    Добавить комментарий

    • Repeat the previous two steps to remove the protective film from all the remaining adhesive strip pairs (labeled 2, 3, and 5).

    What can happen here is the protective covering can break be careful

    • Remove the tape securing the display to the rear enclosure.

Bring a loupe or magnifying glass, and a bright flashlight. And a pillow for the display.

Great guide, I highly recommend a service wedge. I bought a foam one on Amazon that has a removable section so it can be used on a 21.5 inch or 27 inch , and it made the job easy.

fo4ever - Ответить

Be VERY CAREFUL with the bottom strips. I found them very difficult. The front peeled off first allowing the strips to stretch. Made it work but went slow and meticulously. I found the use of a headlamp useful instead of a flashlight.

Danny McFarlin - Ответить

I’ve just upgraded the RAM in two iMacs requiring adhesive strips and had a problem both times. In the first, the white tape on the lower part of the ‘3’ strip broke leaving about 50% behind.. In the second, both ‘2’ tags came off the white tape leaving all the tape still attached to the sticky layer. Both these instances caused a major problem as part of the screen was already stuck down. I had to try to make a gap between the screen and the case to insert a craft knife to loosen an edge of the white tape so I could grab it with my tweezers. Nightmare! Perhaps the adhesive strip kits sold in Europe aren’t as good quality as the ones sold in the US.
