Einleitung

Um das Display am iMac Intel 21,5 " EMC 2638 auszutauschen benötigst du ein spezielles iMac Opening Tool.

  1. SrDNTSYqyhGMRNDC

    • Mit einem frei beweglichen Gelenk kann der iMac unkontrolliert pendeln, das macht es schwer an ihm zu arbeiten. Es geht leichter mit einem iMac Service Keil, es kann aber auch ohne ihn durchgeführt werden.

    • Wenn du die iFixit-Reparaturhilfe aus Karton verwendest, dann baue sie zuerst mit Hilfe dieser Anleitung zusammen.

    • Bevor du beginnst an deinem iMac zu arbeiten: Ziehe den Netzstecker, drücke und halte den Ausschaltknopf für mindestens zehn Sekunden. Dadurch werden die Kondensatoren im Netzteil entladen.

    • Sei sehr vorsichtig und berühre nicht die Leitungen oder Lötstellen an den Kondensatoren auf der Rückseite der Platine des Netzteils. Fasse diese nur an den Kanten an.

    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 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.

    jerrid_foiles -

    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!

    Sam Fung -

    “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.

    Chris Hughes -

    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.

    Phil Tesone -

    I used this service wedge but also found it a very tight fit. The same stabilization can be achieved by using a big rolled up towel.

    Ernst -

    While this is a good instruction guide, I recommend to also look at OWC’s instruction video about drive installation, before starting the exercise. Those install videos are very detailed and useful.

    Ernst -

    Main advice: TAKE YOUR TIME with the pizza roller.

    Make several passes, until you really feel like there's no more sticker in the way. Stay away from the camera though (approx. 1inch / 2.5cm on both sides). This will reduce the work left with the plastic card. Adhesive is really on the edge of the screen so there is absolutely no need to go any further than the recommended 1cm / 3/8inch depth.

    Where are the sensitive parts?

    Facing your iMac, imagine you're looking at a watch. There are antennas on 1, 2 and 4 o'clock. Do not insert any metal piece there (nor anywhere else, btw). Other than that AND the screen cables underneath the camera, not much danger.

    • Setze das iMac Opening Tool an der linken Seite des Displays, in der Nähe des An/Aus Schalters beginnend, in die Spalte zwischen Glaspanel und Rückgehäuse ein.

    • Die Achse am iMac Opening Tool verhindert, dass du es zu tief einschieben kannst. Wenn du ein anderes Werkzeug verwendest, musst du aufpassen, dass du es nicht tiefer als 9 mm in das Display einschiebst.Sonst riskierst du ein Durchschneiden der Antennenkabel, was zu ernsthaften Schaden führen kann.

    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.

    Richard Cook -

    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 Klebestreifen ersetzen

    Alan Digby -

    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 :(

    Nikolay -

    This part of the exercise should be done with extreme patience. I took my sweet time with the opening tool, rolling it through the entire panel and enclosure gap over and over again, until I was very sure no parts were sticking together anymore. And when I thought I was I done, I decided to do it over again.

    Ernst -

    You can "warm up" the adhesive before try to cut it with the tool using a hair dryer. Heat the edges for about a minute, keep moving it so you don't cause stress in the glass. Also the above note.. use the tool and then the cards. Do not use a guitar pick or other objects as the thickness will cause you to break the front glass, which is a bonded part of the display (expensive).

    • Benutze es wie einen Pizzaschneider - Rolle es entlang des Spalts und trenne dabei den Klebeschaum in der Mitte.

    • Achte darauf, dass du es immer mit dem Handgriff hinter dem Schneidrad führst. Wenn du ziehst, kann sich das Rad aus dem Griff lösen.

    • Lasse das Werkzeug die linke Seite des Displays entlang laufen.

    Moreau -

    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.

    • Fahre fort und lasse das Werkzeug um die obere linke Ecke laufen.

    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.

    • Fahre an der Oberseite des Displays fort.

    • Du kannst das Werkzeug mehrmals hin und her schieben. So trennst du so viel wie möglich von der Klebeverbindung auf.

    In this step can I cut along the display without make any damage to the front camera?

    arisnordico -

    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.

    I did all steps like this manuell but now the Display wont work only some colered strips are to see! Whats happend??

    Can anybody help me ? Maybe the connector cable is broken?

    djfanta -

    Check both connectors, probably one of them not seated well

    pzhivulin -

    You can add a SATA SSD if you already have a PCIe SSD Factory?

    kaserlik -

    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.

    pzhivulin -

    omg - forgot to switch the termal sensor from the old display...

    now fan runs like crazy...

    Andrei Balotescu -

    The key thing is to never put any force on the opening tool when working through the tape. Just roll it back and forth with ease.

    • Beende das Schneiden mit dem iMac Opening Tool unten auf der rechten Seite des Displays.

    • An dieser Stelle solltest du noch einmal das Werkzeug um das ganze Display laufen lassen, um wirklich soviel von der Klebeverbindung wie möglich aufzutrennen.

    Yes, do it many times to loosen the adhesive.

    Noah Ralston -

    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.

    • Das Werkzeug hat den größten Teil der Klebeverbindung aufgeschnitten., aber das Display ist immer noch ein wenig mit dem Gehäuse verklebt. Den letzten Rest musst du mit einer Plastikkarte lösen.

    • Lege den iMac mit der Scheibe nach oben auf den Tisch.

    • Beginne in der oberen rechten Ecke und zwänge eine Plastikkarte zwischen Display und Rahmen.

    • Achte darauf, die Karte nicht tiefer als 9 mm einzuschieben. Du könntest sonst Bauteile im Inneren beschädigen.

    this step is extremely important NOT to stick in the cards too far….. doing so, you risk a 600 euro replacement as I experienced………

    Edgar Broekema -

    I drew a 3/8” line on my cards with a marker first.

    Max Romano -

    I’m reading this on the EU store, please change all measurements to cm/mm.

    Morgana Devina -

    @ifixit The next batch of cards you create should have a line printed on the card 3/8” in from the edges. Would make a nice reference.

    Richard Giratd -

    Here’s where OWC provides glass removal suction cups, which is a better solution than plastic cards.

    The suction cups help to easily lift the glass panel, without risking the damaging of any internal wiring that the plastic cards could cause.

    Ernst -

    Better to remove stand wedge at this point? Can’t see from pics

    • Verdrehe die Plastikkarte seitlich und vergrößere so den Spalt zwischen Display und Rahmen.

    • Bewege die Karte vorsichtig und langsam, damit das Displayglas nicht zu stark belastet wird - du brauchst nur einen Spalt von etwa 6 mm Breite zu öffnen.

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

    • Schiebe die Karte zur Mitte des Displays hin und schneide so allen Kleber an der rechten oberen Ecke des iMac auf.

    • Halte unbedingt vor der iSight Kamera an, damit sie nicht beschädigt wird.

    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.

    Felix -

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

    • Zwänge die Plastikkarte erneut in die obere rechte Ecke ein und lasse sie dort stecken. Damit verhinderst du, dass sich die Teile wieder verkleben.

    • Verdrehe die Karte nach oben, vergrößerte so den Spalt zwischen Rahmen und Display ein wenig.

    • Drehe, genau wie an der anderen Seite, langsam und lasse dem Klebstoff Zeit beim Auftrennen. Achte drauf, das Displayglas nicht zu stark zu belasten.

    • Verdrehe nun beide Karten seitlich, wie im Bild zu sehen an den Ecken eingesetzt, und vergrößere den Spalt zwischen Gehäuse und Display.

    • Wenn manche Stellen noch verklebt erscheinen und sich nicht trennen lassen, dann musst du aufhören zu verdrehen und mit einer der Karten die Klebestelle auftrennen.

    • Fange an, die Oberkante des Displays vom Rahmen weg zu heben.

    • Hebe es nur ein paar Zentimeter an - die Datenkabel und Versorgungskabel des Displays sind immer noch am Logic Board angeschlossen.

    • Während du das Display mit einer Hand nach oben hältst, trenne mit der anderen Hand das Stromkabel des Displays.

    • Hebe das Display nur so weit an, dass du genug Platz hast, um an den Anschluss zu kommen, jedoch nicht so weit, dass du die Kabel dehnst und ihre Anschluss überbeanspruchst (~20cm).

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

    bstaud -

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

    Noah Ralston -

    Head lamp gives you the best hands free view!

    Macrepair SF -

    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.

    Ted Horodynsky -

    When reassembling, make sure you get a “click” confirmation that both the levers have locked AND the pins have seated on this connector. I was treated to a black screen upon startup, and had to re-cut my newly installed adhesive strips to get back in to firm up this connection. Better would be power up with the bottom adhesive in place, screen resting in place and held on top with blue painter tape to confirm connections, THEN pull off screen-side adhesive tape covers for final re-bonding.

    Robert McKillip -

    Can someone post a link to actually purchase these cables?

    Jay Hernandez -

    E-bay had one for me

    • Klappe die Metalllasche am Anschluss des Display-Datenkabels mit einem Spudger hoch.

    • Ziehe das Display-Datenkabel vorsichtig aus seinem Sockel auf dem Logic Board.

    • Achte darauf, dass du den Verbinder des Display-Datenkabel gerade aus dem Sockel herausziehst.

    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.

    bstaud -

    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!

    Sam Goldheart -

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

    • Hebe das Display an, bis es fast senkrecht ist.

    • Es gibt immer noch einen Klebestreifen an der unteren Kante des Displays, der den Display wie eine Art Scharnier mit dem Rahmen verbindet. Klappe das Display einige Male auf und zu, um den Kleber zu lösen.

    Where can I find a replacement display for my iMac?

    iFixit has listings for replacements. Go to the Parts section

    • Wenn nötig, kann eine Plastikkarte helfen, den unteren Klebestreifen vollständig zu abzutrennen.

    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.

    phil -

    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.

    Rory McKenna -

    YES, exactly the same here. more but more simple.

    Lucio Alves -

    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.

    marty -

    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.

    Ben Varela -

    This worked great! look for small left over adhesive on either edge of the bottom of the screen and pull each one towards the center. Screen assembly removes after that with no fuss.

    • Hebe das Display nach oben aus dem Rahmen und entferne es aus dem iMac heraus.

    • Möglicherweise musst du an einer Seite anfangen, das Display langsam anzuheben, um den Rest des Klebebandes zu lösen.

    • Sei vorsichtig bei der Handhabung des Displays. Es ist groß, schwer und aus Glas.

Abschluss

Um dein Gerät wieder zusammenzusetzen, folge den Schritten in umgekehrter Reihenfolge.

I just broke mine... when i put inside the master card.... :(((( how to proceed? its a screen not a glass - need to repair whole screen from apple.... i was trying to put ssd drive inside...

Сracks only at the edge in one place and its work but :(((((( how can get in now???

Anushka -

Hi, where can I buy a replacement display for my iMac EMC 2742 (2742 is the same as 2638, I assume?)...Thanks so much!

Cameron -

I put off replacing my hdd with an ssd on my late 2013 iMac because it looked a bit tricky. This guide and an iMac opening tool made the job really strait-forward. Just be gentle and patient and the screen comes off with very little bother. Thanks ifixit!

Giles Tanner -

Used this and the adhesive guide to replace the cracked display on a relative’s 21.5 inch iMac. Thank you, iFixit! These guides and the toolkit I purchased from iFixit years ago have saved me roughly $200.00 vs. having a repair shop do it. I still have a 2008 24inch iMac up and running thanks to this website!

fo4ever -

I used this guide and successfully replaced the stock HDD with a Crucial 1TB SDD MX500 and upgraded the RAM to 16GB, blew out all the internal dust and now it runs beautifully and didn’t have to buy an entirely new iMac.
