iMac Intel 24" EMC 2267 CPU Replacement

Step 1

Lay your iMac front side down on a table with the lower edge facing yourself.
Loosen the single Phillips screw in the center of the access door.
This screw is captive in the access door.
Remove the access door from your iMac.

The grid won't fall off by itself. You'll have to help it. Use the smallest screwdriver you have; the Torx 6 worked fine for me. It should enter in one of the many holes composing the grid. Use it as a lever to ploy the grid a little bit. You may catch it with your fingers and that's it.

Be carefull not to damage the hole by a too strong leverage.

Laurent -

much more safer to use duct tape, instead of torx 6. (glue it along the length of the grid and pull). it will loose instantly and smooth;)

Anyone know a guide to replace the plastic piece this screw connects to? I accidentally forgot this step - went to remove the front bezel and bent the plastic piece the access door connects to.

Step 2

The glass panel is fixed onto the front bezel with fourteen magnets around its perimeter.
Stick two suction cups to opposing 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.

A good alternative to the two heavy duty suction cups is a regular household plunger.

Russell Knight -

Also, 2" wide packing tape. Maybe a 6 or 8" piece, folded in the middle to give you say, a 1-2" "handle". Make a pair of these. They look like a capital T but with a short vertical part (the handle), and a wide top I the sticky wings). Get the good 3M tape, it's strong, and it peels off clean without leaving any glue from the screen.

Barry Coyle - 30/01/16

for me one household plunger did the trick!

Ronald Huygen - 04/11/17

Step 3

Gently pull the glass panel straight up off the iMac.
The glass panel has several positioning pins around its perimeter. To avoid shearing these pins off the glass panel, be sure to only pull straight up during removal.
Be meticulous about cleaning the LCD and the inside face of the glass panel before reinstallation, as any fingerprints or dust trapped inside will be annoyingly visible when the display is on.
When replacing the glass, be sure there's nothing between the glass and the frame. Stray cables could be damaged or crack the glass.

Another approach that worked for us was to get 4 small plastic wedges (the kind used in iphone screen replacements). Working one corner at a time you can use a cheap suction cup to pry just that corner up enough to slide the wedge in. Then proceed to the next then next, etc. Once all 4 have the wedges under them the glass should be away from the body all the way around, then just carefully lift it the rest of the way up.

Step 4

Remove the following 12 screws securing the front bezel to the rear case:
Eight 13 mm T8 Torx.
Four 25 mm T8 Torx.
On the 24" iMac Intel Model A1225, the bottom center two screws are long (26mm), four on sides (two left, two right) are medium (18mm), and the remaining 6 (four top, two bottom corners) are short (14mm).

I would strongly suggest taping the screws down on a piece of paper towel or cloth in the same order you take them out, as there are different lengths in no particular order and they don't all fit into just any hole. Unless you keep track of which hole each screw belongs, there is no other way of knowing. I stress taping because I didn't tape mine down and after bumping the table I was working on they scattered, leaving me to guess.

Len -

Even better, use an ice cube tray to keep the screws from each step together.

maccentric -

how about using the magnets near the screws to keep their positions?

Andy -

I use an 18 count egg carton (or two) and label each egg slot with a Sharpie. Works great.

airira -

As a rule with iFixit repairs, for years I've been printing the guides, applying scotch magic tape near each picture (which allows me to reutilise the paper prints in the future), neatly putting the appropriate screw next to their picture and taping them down with scotch magic tape.

Even if I have to wait for spare parts, this allows me to neatly file the guide + screws in a copy safe and a binder (or in a cardboard filing box together with the rest of the parts) for later reassembly. Hardly any mistake possible...

Bart Van Dessel - 02/10/14

I think the caption on the picture is wrong here for 24" iMacs - it says: "On the 24" iMac Intel Model A1225, the bottom center two screws are long (26mm), four on sides (two left, two right) are medium (18mm), and the remaining 6 (four top, two bottom corners) are short (14mm)." I think actually bottom centre two are long, then all the rest are medium apart from the two either side of the CD/DVD drive

HBloomfield - 12/03/15

I print out the steps. Get a roll of scotch tape ready. Every screw, or set of screws I remove, I lay on some tape, and then tape them to the number on the directions. Then you have each screw labeled, with direction, and in order, or reassembly. Just working backwards in the directions.

Barry Coyle - 30/01/16

I agree with @HBloomfield’s comment overall, but to add to that comment, mine was a little different.

(2) Long: bottom center

(4) Medium: bottom left and right; on either side of the CD/DVD drive

(6) Short: everything else

Jake Thornberry - 04/08/20

Yes Jake I found the same with my iMac Model A1225.

Andy -

Be careful with the thermal sensor wire so that it won't get under the second bottom screw from the left.

Sami k -

Step 5

The front bezel is still attached to the iMac by the microphone cable.
Gently lift the front bezel from its top edge off the rear case.
Once the top edge of the front bezel has cleared the rear case, rotate the front bezel toward the stand and lift it off the rear case.
Rotate the front bezel away from the rest of the device and lay it above the top edge of the iMac.
When reinstalling the front bezel, start at the lower edge and make sure it is flush with the rear case before lowering the top edge onto the iMac.

Contrary to the pictures, to lift the front bezel off, start at top of the computer screen lifting up while apply a little bit of pressure to the foam in the upper corners of the screen. This will give you the leverage needed to get the bezel to lift up. Be careful to not pull to fast, as the camera cable is still attached.

armand - 07/08/15

you'll need to add this step in all the other tutorials about iMac 20" EMC 2210, where it is missing ; they all jump from step 5 to step 6, which is a little annoying...

Armel h - 10/11/16

Easy way to remove bezel, insert the longest screws a quarter turn into the two top most edge screw slots. Use the screws as anchors to press against as you pull the bezel toward you. Then a simple twist to remove the screws, and the rest of the bezel comes off easy.

armand - 14/04/17

Step 6

Disconnect the microphone cable connector, removing tape as necessary.
For the front bezel to sit properly, be sure to tuck the microphone cable and connector into the void next to the camera board.

During reinstallation of the LCD panel, be sure that the iSight microphone cable does not become trapped behind the panel.

Ocean Yamaha -

I actually didn't have to remove the cable. With the iMac laying on its back, just rotate the front bezel (bottom edge rotating around top edge) so that it's laying upside down, above the iMac. When reassembling, just rotate back into place.

Brian Tsai - 14/08/15

Step 7

Remove the two 5.3 mm T6 torx screws from the LCD connector.
Firmly grasp the pull tab on top of the connector and pull it straight up out of its port.
Make sure that you are pulling the tab and not the connector cable.

remove the 8 screws (torx) that is holding the screen.

Gideon Lamprecht -

I actually had to use my 6H torx. my 4/5/6’s wouldn’t grab. Whether its from stripping or whatever the 6H worked fine.

Thomas Keats - 07/04/21

I completely stripped one of the T6 screws. If you did too, they are M2 screws. An M2x6mm with a couple washers works fine.

When reassembling, it’s probably a smart move to reconnect this cable before putting the display-holding T8 screws in.

Dave - 13/11/21

Step 8

Remove the eight T8 Torx screws securing the display panel to the rear case.
The iMac shown is a 20" model, but the screw locations should be approximately correct.

Step 9

Place your hands on either side of the bottom of the display panel, and lift it up enough that you can reach the connectors inside.
Do not try to remove the display panel completely as it is still connected to the rest of the device.
While holding the display panel up with one hand, locate and remove the display thermal sensor cable from its connector.

Make sure you reconnect the cable for the thermal display sensor during reassembly. If you don't, the fans will be running at max speed and you might think it is from the drive thermal sensor afterwards (which is an issue some users have and which can be fixed in software).

jnavarro - 14/12/14

I had great success with just propping the top edge of the LCD display up with a box about 8" long. By doing so, I didn't have to remove the thermal sensor wire or the power cable.

Brian Tsai - 14/08/15

The thermal sensor connection is more of a pain than it seems. It's a cramped area and it's not clear when it's properly plugged in during reassembly. It may *feel* like it's in, but then pops free at the slightest touch. I guarantee that if as soon as you start up, fans running max speed instantly is the indication this is the issue. If you're ok with that, then fine, but otherwise, you'll have to pull it apart again.

Sheldon Carpenter - 31/07/17

Unplugging the thermal sensor connection is easier said than done, but using the spudger here is very

helpful

Peter Bull - 12/12/17

Brian Tsai has it RIGHT! I purchased the OWC SSD and bracket (NewerTech AdaptaDrive). Using the bracket box to support the LCD screen up on the upper left corner and getting adequate illumination it was really easy to change out the drive. Note - i used a knife to pop off the thermal sensor OFF THE DRIVE (not the PCB) as in Step 21, used the knife to pry off the connectors as in Step 16. I suspect you don’t even have to do Step 7.

don delwood - 06/02/21

Step 10

While still holding the display panel up, use two fingers to firmly push down on the power supply cable connector from its socket.
Be very careful not to touch the exposed face of the power supply to avoid electric shock from the many large capacitors attached to the other side of the board.

When putting this back together it can be extremely difficult to plug this cable back in without removing a guard that is held in by 2x T8 Torx screws just next to it.

Russell Knight -

I will suggest to remove the other end of the socket which is connected to the display panel. You can never imagine how difficult it will be to plug in on the main body, unless you know well about it.

Michael Shi -

I didn't realize these comments were HERE? Poor web design if you can't see comments in an obvious way. Step 10 will cause you the most trouble in reassembling the computer and I knew it as soon as I popped that connector out off the board. Its really f*cking hard to get that connector hooked back up in the way it should be and I have small hands. I managed to get it at least partly pushed in after several tries. Over all it took over half an hour to get it back in there right and scared the !@#$ out of me because I didn't think I could get it done. Those stupid little plastic things won't help you here, the connector really needs to be pushed hard to get it back in. I ended up using a big beefy screw driver for slotted screws, about a ten inch long screwdriver. I used the blade on each end of the connector and was able to give it a good hard push on one end, then pushed on the other end, slowly rocking the connector back into full flush contact. Be real careful you aren't pushing on the ribbon at all.

sdpickups -

Having done this procedure 6+ times now, I can tell you it's much easier if, instead of holding the panel up by the "bottom" as illustrated in the guide, instead raise it by the "left" side. It gives you (me) much more room to get fingers behind the connector.

May have been obvious to some, but this little adjustment didn't jump out at me until the 2nd or 3rd rebuild.

Jeff Dickson -

There are four screws holding the power supply in place. Two different thread types so make note! Then lifting the power supply enough to easily plug the power cable back in is MUCH less of a problem. Then put the four screws back and proceed on.

racecornell -

That´s exactly how I managed reassembling this connector very easily: Open the four screws, that hold down the platine and then lift it up a little bit.

info - 16/10/14

It isn't that hard if you start by hold the display panel up perpendicular to the case on the side of this challenging connector. From here you'll be able to connect the cable, then follow through with the two other connectors (two screws on the last one). Worked great for me.

cjrocksu2005 -

By far this was the most difficult cable to reconnect. I enlisted a second person to hold the display after I unscrewed the power supply (Torx 10, 4 screws) and was able to give my fingers adequate room to securely reattach it. There's no need to do this when disconnecting the power supply, but it would take more nimble fingers than mine to reattach it without loosening the power supply.

Ron Lockhart -

Do not remove this cable....! Too hard to get back there... I had to screw and lift up the whole platine to get the f**** cable back there....

EASIER IS:

# just remove the mic-cable (step6),the Thermal sensor (step9) the LCD-connector (step 10)...

# then let someone lift up (works also alone) the screen on the right side (there where Superdrive is)...

# remove Drive and Replace!!!!!

# Reconnect the easy cables....

anselm pavlik - 01/05/14

agree! this cable is really tricky ...

Johann - 02/09/14

This step is TOTALLY UNNECESSARY on a 24" model!

Skip it; you have enough space to lift the panel.

Robert MacLeay - 14/01/15

You don't need to do this step at all - you can leave the panel connected to the circuit board while you replace the hard drive. I did this while replacing the drive on my 24" iMac, just resting the panel on a box I had put next to the iMac on my desk, so that the panel stayed at the same level but was just moved and rotated sideways, with the cable still connected.

HBloomfield - 12/03/15

I had great success with just propping the top edge of the LCD display up with a box about 8" long. By doing so, I didn't have to remove the thermal sensor wire or the power cable.

The power cable actually has a fair amount of play in it IF you peel back the thin black tape that affixes it to the LCD panel side to expose the power cable connector on the LCD side.

Brian Tsai - 14/08/15

Note: SERIOUSLY:

- Disconnect the temp sensor from the iMac

- Lift up the screen from the RIGHT side (as if the iMac were standing up, facing you) to a vertical position

- Peel back the tape on the back of the LCD to expose the power supply connection

- Pull the connection from the LCD

- Attachment is the reverse

MUCH easier
