Introduction

Removing the display on an iMac Intel 27" Retina 5K 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 in place, so you'll need to apply a new set of adhesive strips.

  • 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.

I found that using a couple of paperbacks (one larger than the other) performed the same function - taller one placed to the rear of the stand and the other one in front accommodated the curvature perfectly.

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

    • You may need to use a small amount of isopropyl alcohol and a lint-free cloth to wipe away any left over residue.

I've done this on several iMacs now, but today I noticed another layer of thin black plastic stuck to the back of the display.

It was really tough to remove and left a lot of clear, sticky goop under it.

It's really thin, but it was strong enough to hold the screen in place by itself - I reconnected the display cables and tested before pulling the backing off the new adhesive strips - and it stuck together!

I had to pry it apart again and it actually ripped my new glue strips in 2 or 3 places. I was able to still use them, but it did not go as smoothly as other iMacs I've upgraded. Everything was fine in the end, but I left some blue painters tape on the top of the screen overnight so the glue strips will set up without the screen falling off - just to be on the safe side.

Does anyone know if this last layer of black plastic on the screen should be removed or left in place when replacing the glue strips?

That Black layer of plastic should not be removed. I found that on some segments, upon peeling back old adhesive remnants, the thin black plastic layer would also begin to peel off. STOP and cut off what has been removed, separate the black plastic strip from the adhesive remnant you are peeling off. The continue removing remnants.

  • Start with strip 13, 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.

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

Add Comment

  • 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 pull down against the spudger to ensure the strip is taut, and stick it onto the frame.

  • Once you're satisfied that the top half of the adhesive strip is neatly aligned, peel the longer piece of backing out from behind the strip.

    • If the top 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.

  • Align the lower portion of the strip with the right edge of the frame, and stick it down.

  • Use your finger to smooth all of strip 13. 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.

Add Comment

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

  • Working counter-clockwise from strip 13, place:

    • strip 12 on the top right

    • strip 11 on the top left

    • strip 16 on the left vertical

    • These three strips have a hole at each end—always use the smaller hole for alignment for more precise placement.

  • On the iMac Intel 27" Retina 5K Display, strip 12's blue tabs will not line up with the top antenna in the same way as the regular model. This is perfectly acceptable and won't impact the performance of the strips or antenna.

  • The two remaining strips (14 and 15) 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 14 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.

Using iFixIt’s adhesive strips, i cannot strip off the white backing. Pulling on the tab pulls the wrong backing off, the black backing. I can:t figure a way to do this correctly!

The video shows the correct method - attach these strips to the back of the screen rather than the iMac itself.

  • Repeat the previous step for the 15 adhesive strip, placing it along the left half of the bottom of edge of the iMac.

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

You've really got to pay particular attention to exactly where to stick these - especially the short right-angle part as it doesn't go on the back of the glass as you might expect but actually over part of the edge of the LCD. It's also really difficult to remove and reposition the stickers since they will stretch when pulling them off.

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

  • 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.

  • 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 16.

  • Gently insert the display data connector into its socket on the logic board. Be sure to press it straight into the socket, and insert it completely.

  • Flip the display data connector lock down onto the socket.

  • Insert the display power connector 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.

Add Comment

  • 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 15 strip by reaching in from above and pulling the tab straight up from the bottom edge of the display.

  • Repeat the previous step for the 14 strip.

This guide works great. Replaced a 2015 IMAC 27" screen without any difficulty especially since I purchased the Ifixit tape kit and removal tools. Thanks guys and gals. Couldn't do it without you.

will this work on late 2015 27"5k iMac

Hello, I got a Late 2015 iMac 5K, are the stripes the same?

filmore - Reply

yes .it works

Walter Fontes -

Yes this adhesive strip replacement kit works for the Late 2015 Retina 5K iMac. As mentioned in step 8, the tabs for strip 12 won't line up exactly the same as shown in the guide but it does not matter. It still works and will not interfere with that antenna.

Does this work with iMac 27 2017?

macdeutsche - Reply

Used these guides to replace the cpu and ssd’s in my 2015 iMac 27”. Super easy! And yes with a late 2015 model, the cpu is replaceable with a regular Skylake cpu. I bought a 3.2 i5 model and replaced with a 6700K ! And yes these also take 64GB of DDR3. For the PCIE SSD you can get an adapter off of ebay…look for m.2 to iMac adapter…since they’re cheap I recommend getting like 2-3 and figuring out which one works best with your m.2 ssd. So yeah, you can get a 1TB m.2 AND a 1TB 2.5” ssd in this and have a nice little box for peanuts.

Friends! This manual and accessories are compatible with the iMac 27 5K 2017?

Hi,

I done all of the above on my 2017 27inch iMac and now my microphone won’t work, when I tap the enclosure it reacts but it doesn’t hear my voice commands. Maybe the adhesive tape got stuck on the microphone somehow. where is the microphone located exactly? Help please……

Best regards, Henk
