Remove the LCD to access most of your iMac's internals.

    • Before beginning, unplug your iMac and lay it on a soft surface as shown.

    • Stick a suction cup near each of the two top corners of the glass panel.

    • To attach the suction cups we sell, first position the suction cup with the movable handle parallel to the face of the glass panel. While lightly holding the suction cup against the glass, raise the movable handle until it is parallel with the other handle.

    • If your suction cups refuse to stick, try cleaning both the glass panel and the suction cup with a mild solvent.

    Very easy to lift the glass out. Don't jerk too hard.

    Another comment on DATA & LCD Temp. Sensor cables: I had to remove the vertical sync, and the backlight cable, however, if you have an assistant or/can carefully rotate the screen clockwise/and then have it held up about 5" to 6" at a slight angle, you do not need to remove LCD data cable or LCD thermal cable, however - IMPORTANT: you must have a second pair of hands/or way to securely prop up the LCD. Also, don't rotate too much, since then you will pull out LCD data cable, and it renders the whole exercise moot, or can damage the cable or connector.

    MaximBorzov - crwdns2853112:0crwdne2853112:0

    You don't need suction cups. The screen, held by magnets, can simply be pried off using a very thin blade such as a screw driver and fingers.

    Deepsurvival - crwdns2853112:0crwdne2853112:0

    That's a bad idea. using a metal tool to pry off glass is likely to end with an expensive broken front glass.

    Suction cups are common. Find a couple and do it the safe way. I use some cheap ones that came with iPhone repair kit.

    max damage -

    No need for suction cups, I just stuck my nails (short like guys usually have) between the top part of the screen and body, and it came off easily. I've never done it before, so it seems to be very easy.

    Just completed the replacement of the optical drive with an SSD using an OWC Data Doubler kit. Attempted to remove the optical drive without disconnecting any cables but found it a bit fiddly to orient the screen for good access. I bit the bullet and disconnected them and found the process less daunting than I imagined. Reconnecting them was similarly straightforward if you're careful.

    Tip: you can skip the step for removing the optical drive thermal sensor connector from the motherboard. Still need to remove the sensor from the optical drive but you can leave that hanging and reattach it to the SSD later.

    I’ve just successfully installed a 1TB SSD in place of my optical drive thanks to the information here- thank you to everyone who has contributed!

    3 comments- the procedure described here seems to vary between HD replacement and dual HD/optical drive replacement. This can be confusing at times.

    Expect there to be minor differences between the layout described and what you find when you open up your iMac. There are also, surprisingly, differences between the HD enclosure description, and the article provided by ifixit.

    I was able to replace the DVD/HD enclosure single-handedly without fully removing the LCD, or deconnecting any of the cables (steps 5-11). It’s a bit cramped, and fiddly, but I was not happy removing any of the cables despite watching videos, etc., since they all seemed to involve applying more force than I was comfortable with. A more detailed description of how to release them might have helped, but even here, there may be minor variations even within the 2389 model.

    Good luck!

    I did it several times with one suction cup at the end of a kitchen brush. Once with the blade of a swiss army knive, also ok. And i’m pretty sure it works with fingernails too

    Tai - crwdns2853112:0crwdne2853112:0

    Fingernails are all you need to free the glass from its magnetic hold. If you don’t have them, slip something thin and plastic, like a spudger, at a top corner.

    Minha dúvida é a seguinte: após o técnico trocar o HD do meu iMac de 21,5 polegadas, a câmera parou de funcionar. Seria por causa da troca do HD? Tem solução?

    Claudio - crwdns2853112:0crwdne2853112:0

    Creio que o cabo da camera não foi plugado ou deu mau contato… ou até danificado.

    I can’t get my glass to budge. I’m replacing a cracked one and now it’s about to shatter.

    jamboxmitchell - crwdns2853112:0crwdne2853112:0

    I know that I'm replying really late but I advise to use clear tape over any cracks so the cracks don't get bigger

    Jace Holmes -

    Check for chips in the glass BEFORE you do this step. If there is a chip when you pull up with the suction cups you will wind up with a jagged mess. If you do have a chip I would advise covering the screen near the chip with clear tape of some kind before lifting out. Mine shattered right at the chip and the resulting glass dust cloud got all over. My solution was buying a new glass screen.

    • Gently lift the glass panel perpendicular to the face of the LCD enough to clear the steel mounting pins attached along the underside of the top edge of the glass panel.

    • Pull the glass panel away from the lower edge of the iMac and carefully set it aside.

    • During reinstallation, be sure to meticulously clean the inside of the glass panel and the face of the LCD as any dust or fingerprints trapped inside will be annoyingly visible when the machine is turned on.

    What's the best product to clean the face of the LCD?

    Try your best not touch it in the first place

    Wearing Nitrile or regular surgical gloves helps prevent finger prints if you accidentally touch the glass.

    • Remove the eight 8 mm T10 Torx screws securing the display to the outer case.

    • The last two pictures are detail shots of each side of the display.

    On reassembly, it is REALLY HARD to align those screws, because of the field of the strong magnets that hold the glass cover on. I'm sure there's a trick to it, but I'd love to know what it is for future reference.

    Peter Shenkin - crwdns2853112:0crwdne2853112:0

    I used needlenose pliers and the T10 to align the screw into the hole. Otherwise the screw keeps jumping to the magnet. And patience with this NON-CAPTIVE screw design (c’mon Apple, even **I** came up with that, and I’m an idiot!)

    finnik2d - crwdns2853112:0crwdne2853112:0

    A short piece of small gauge vinyl tubing that fits tightly over the head of the T-10 driver leaving an 8th of an inch or so in which to insert the screw to engage the head will hold the screw long enough to keep it away from the magnet and get it going in the hole.

    Paul Boudreau - crwdns2853112:0crwdne2853112:0

    I use non magnetic SS curved tip tweezers together with a magnetized #10 torx bit both to remove and reinstall the screws. You can magnetize and demagnetize the bit using the strong magnets on the LCD frame. Don't worry too much during removal, you can recover the screw. But loath the moment you drop the last screw during reassembly. For that reason, reinstall the screws near the magnets and hardest to get to first.

    • Slightly lift the top edge of the display out of the outer case.

    • Do not lift it too much. There are several cables attaching the display to the logic board.

    When putting the display back I have resistance from the foam elements (on the top end where the iSight is) and have to press down really hard. Is that okay?

    • Pull the vertical sync ribbon cable out of its socket on the LED driver board near the top left corner of your iMac.

    • The vertical sync ribbon cable has a ZIF style end, but the socket has no lock or retaining flap. Simply pull the cable away from its socket toward the optical drive side of the iMac to disconnect it from the LED driver board.

    The vertical sync cable was snug initially and now is loose. I checked and the cable is intact. Has anyone had experience with making it fit better?

    Rajan - crwdns2853112:0crwdne2853112:0

    Scotch tape on the upper side and sliding this in helped to secure the cable.

    Rajan - crwdns2853112:0crwdne2853112:0

    Reassembly of this part was the closest I came to disaster on this project. I tried inserting the connector a few times without success, and when I looked it it the leads, which are fragile, were all mangled. I smoothed them out by hand as best I could and and reinserted, very carefully this time. The trick is that the tip of the connector should be pointed somewhat upwards when reconnecting.

    I was pretty sure that when I was done, I would reboot but have no display; but fortunately, everything worked.

    Peter Shenkin - crwdns2853112:0crwdne2853112:0

    Hi, I still have a question. What is the "Job" of the vertical sync ribbon cable. Thanks

    Lutz Blum - crwdns2853112:0crwdne2853112:0

    So let’s say someone wanted to suck some of the dust off the back of the display before reassembly. Let’s just say that. Someone would likely suck this forsaken cable up into the vacuum tube then, wouldn’t they? They might. And if it were to oscillate in a rushing torrent of air, it might get munged? It might.

    Here’s how you overcome such a disaster:

    1) cut the end fresh, as close to the end as you can while cutting off any frayed end.

    2) abrade the end gently, repeatedly, along the connector wire axis. I used emory paper. Your goal is to expose the copper conductors in the last 1/4” of the fragile evil wire.

    3) Tape a small stiff cardstock to the back of the end of the connector. This is essential to press the connector wires into the connector.

    4) Gently insert, taking special caution to not peel the copper off of the connector.

    5) Tape that connector down deftly, without letting it move a millimeter and securing it for all time.

    sydnius - crwdns2853112:0crwdne2853112:0

    I just leave it connected. After disconnecting the other cables, there is enough slack to lay the display on its backside if you’re working on a flat surface.

    Duane Johnson - crwdns2853112:0crwdne2853112:0

    I have replaced the hdd in this model about 8-10 times - I have never had to disconnect any cables other than the sata and temp sensor cables on the hdd. I just prop the lcd up with an egg carton (or something about 3 inches high that is soft and light) and access the hdd that way. The only thing I ever have trouble with are is putting the LCD screws back in around the magnets - but I have pretty much perfected that with a sissor/ tweezer tool.

    Danny Shaw - crwdns2853112:0crwdne2853112:0

    I followed Suzanne’s comment and also did not disconnect this cable (vertical sync ribbon cable) to avoid damage. I pivoted the screen about 110 degrees after the other cables where detached. On a flat surface, this is easily done and the cable is not tight. Image of my angle if I can drop a link. and cable in this position not in tension.

    • Rotate the display out of the outer case enough to disconnect the LED backlight power cable from the LED driver board.

    • Disconnect the LED backlight power cable by depressing the locking mechanism while pulling the connector away from its socket (toward the bottom edge of the iMac).

    I found it easier to very slightly lift the front edge of the black connector with a small spudger, then gently pulling away towards the bottom of the iMac. Pressing felt a little crude and didn’t work for me.
