Substituição da tela do iMac Intel 21,5" EMC 2638

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.

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

It is very easy to crack the glass in front of the LCD during this step. I used the guitar pick, maybe it was too thick… crack is just on the frame but anyway it is disappointing :(

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.

Ne pincez pas l’écran avec l’autre main. Vous exercez une pression inutile sur le verre et empêchez la roulette de couper le joint.

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.

Yes, do it many times to loosen the adhesive.

Would be good data to show the 3 areas (wifi antennas where the "tape" is larger and covers them. The rest of the "tape" is 1.4" and easy. Also after removing the display, be sure to remove the old "tape" from both the display and the rubber parts of the case. Use the spudger to start an end and it should pull off easily. Careful on the baackside of the display as you can scratch off the black paint/covering.

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.

This part must be done very carefully or you can damage the flat cable from display, despite it was under a iron cover.

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.

Using glass removal suction cups will avoid running this risk of damaging the camera (or any wiring).

Pulling the display power cable by the wires makes me nervous..

I had a small flight light ready so I could see. Follow the directions - don’t blindly pull.

Head lamp gives you the best hands free view!

To clarify, the connector pulls out in the plane of the logic card, not perpendicular.

el flex de repuesto es el 923-0281 ?? muchas gracias

Cutting through this extra adhesive on the bottom took a bit more effort than the step and picture implied (to me). Unlike the other edges, here don't be afraid to really push the card in there to break the seal, there's nothing behind that adhesive that is breakable.

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.
