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.
-
-
-
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.
Don’t get too worried about starting exactly where the picture says. The glue is stronger in some parts so just start wherever is easier and then work slowly and patiently around in the direction shown.
As this guide doesn’t cover replacing the adhesive strips, I found referring to the following was useful (noting that it’s not for the same model of iMac, so the modification they mention wasn’t necessary): iMac Intel 21.5" EMC 2544 Adhesive Strips Replacement

-
Use the tool like a pizza cutter—roll it along through the gap, and it will cut the foam adhesive through the center.
-
Run the tool up along the left side of the display.
If re-opening a screen that was opened and re-attached using iFixit’s adhesive strips, I would strongly recommend heating it first with an iOpener, heat gun or hair dryer. 20 minutes after attaching with the iFixit adhesive I tried to open it again with the pizza slicer to fix something and cracked the screen on the left-hand side.

Continue along the top of the display.
In this step can I cut along the display without make any damage to the front camera?
Hi! Actually - there is no need to cut the tape around the camera area - there is no tape to cut at all! And so, the way go is easy - just pass 10 mm to the left and to the right from camera and start cutting!
P.S. Just did the whole procedure to replace a RAM and to add SSD on PSIe an hour ago! Seems to be different reading the instructions... you know - 2/10 and so on. But it's really not that hard, trust me. I'll give it 5/10.
P.P.S. By the way there is one trick to pass the difficult steps. Any action which requires pulling smth (motherboard, speaker, power supply unit) from the narrow crack (or should i say - slit?) at the bottom of your Imac is really not so easy.
And the trick is to first remove a thin metal stripe with some kind of insulation on it which held by 5 small (very small!!) screws at the bottom of your Imac. After you done it - it's easy to pull everything! Pay attention to the fact that one of this 5 screws at the center are more shortly than others.
If you're changing cracked EMC 2638 display to new assembly, there's two more steps:
Step 24: 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 display assembly.
Step 25: Use the tip of a spudger to unplug bracket of the thermal sensor small cable near display data cable.
Carefully remove scotch tape covering thermal sensor. Using iSesamo or flat tip of the spudger carefully peel the thermal sensor away.
omg - forgot to switch the termal sensor from the old display...
now fan runs like crazy...

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

Starting from the top right corner of the iMac, wedge a plastic card between the display and frame.
this step is extremely important NOT to stick in the cards too far….. doing so, you risk a 600 euro replacement as I experienced………
I drew a 3/8” line on my cards with a marker first.
I’m reading this on the EU store, please change all measurements to cm/mm.
-
-
-
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".
This part must be done very carefully or you can damage the flat cable from display, despite it was under a iron cover.
-
-
-
Slide the card toward the center of the display to cut any of the remaining adhesive along the top right corner of the iMac.
You don't need to do it like this, simply open the iMac bendidng the LCD completely and use the pizza cutter to remove the adhesive.
Agreed. The card is too thick to cut through the adhesive in this way. Use the pizza cutter or a sharper blade at this point.

While holding the display up with one hand, use the other hand to unplug the display power cable.
I had a small flight light ready so I could see. Follow the directions - don’t blindly pull.
bstaud - The display power cable has two squeezable levers on each end of the cable’s width.
Squeeze the left lever with your thumb while you simultaneously squeeze the right lever with your
index finger, and gently pull the cable straight back and out, and the cable comes out very easily.

-
-
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.
Sure could use a magnified picture of this connector and socket, especially the first time you go in. And it is the most critical step of the whole operation — bung it up and we’re toast.
Hi bstaud! If you hover over the image you can click on the magnifying glass and get a large image of any guide photo. Hope that helps!
To clarify, the connector pulls out in the plane of the logic card, not perpendicular.

-
-
Lift the display up to a near-vertical position.
Where can I find a replacement display for my iMac?
iFixit has listings for replacements. Go to the Parts section

cutting through the adhesive is unnecessary if it's not been opened before (outside of an apple store) there will be a tab at the end of each VHB strip that you can use to simply pull the vhb strips off.
YES, exactly the same here. more but more simple.
To save a few steps and a bit of time, if you have a helper, they can hold the display at a 90° angle while you unscrew the brackets and remove/replace the hard drive rather than remove the display entirely. Also reduces the likelihood of damaging the display as you remove and handle it.
The proper way to remove the display according to the Macintosh tech manual and videos is as Rory McKenna and Lucio Alves have learned is to pull the tab at the end of each VHB strip until it is off.

Use the tip of a spudger to flip down the metal retaining bracket on the iSight camera cable.

Excellently described procedure - it worked ok not disconnecting the AC power cable. Only item missed was to disconnect the right speaker - and then not to forget about keeping it out ready to connect when reinstating the mother board!
Thank you very much
The wedge is an extremely tight fit for this model. I was worried that the amount of force needed to use it as shown might damage the stand, so I used it with the long side down instead. It worked fine that way and didn’t need anywhere near as much force to insert.

Here’s a good YouTube vid on upgrading the RAM: Can a Normal Person Upgrade the RAM in the 2017 21.5" iMac?

Here are a couple tips from me:
1) Expose the adhesive to extreme temperatures. I did this by transporting my iMac in my car, screen-down on a piece of cardboard on a cold February morning (in Chicago). When I went to pick up the iMac, the screen practically fell off the chassis. I would have been distraught by this if I hadn’t already planned this replacement. So it was a happy accident.
2) Remember to expell the residual power from the power supply by pushing the power button while the iMac is unplugged. This does NOT guarantee it’s safe to touch, but when I accidentally brushed the solder and exposed capacitors, I didn’t get shocked.

Instead of using the wedge, I placed the iMac faced up with the top side (web cam) facing me while I ran the pizza roller around. It worked out great!

“All iMacs also come with a traditional hard drive” mine doesn’t!! it’s HDD bay is completely empty, no SATA cable or anything. I guess I’ll have to upgrade the PCIe SSD instead.

There is no replacement glass for this model, it is part of the LCD and impossible to remove or replace- the entire LCD has to be replaced unfortunately if the glass is cracked or damaged. You will have to Google search for a replacement. Also be careful with some of the lock tight tork screws as I broke one of my screw mounts taking one out.
