  1. iMac Intel 20" EMC 2266 Inverter Replacement, Access Door: adım 1, 1 resimden 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 - Yanıt

    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.

  2. iMac Intel 20" EMC 2266 Inverter Replacement, Glass Panel: adım 2, 2 resimden 1. iMac Intel 20" EMC 2266 Inverter Replacement, Glass Panel: adım 2, 2 resimden 2.
    Bu adımda kullanılan alet:
    Heavy-Duty Suction Cups (Pair)
    $14.95
    Satın Al
    • 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 - Yanıt

    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 - Yanıt

    for me one household plunger did the trick!

    • 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.

  4. iMac Intel 20" EMC 2266 Inverter Replacement, Front Bezel: adım 4, 1 resimden 1.
    • 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 - Yanıt

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

    maccentric - Yanıt

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

    Andy - Yanıt

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

    airira - Yanıt

    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 - Yanıt

    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 - Yanıt

    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 - Yanıt

    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 - Yanıt

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

    Andy - Yanıt

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

    • 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 - Yanıt

    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 - Yanıt

    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.

    • 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 - Yanıt

    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.

    • Pull the LCD temperature sensor connector straight up off its socket on the logic board.

    • (located at the top of the logic board on the 24")

    • Remove the two T6 Torx screws securing the display data cable to the logic board.

    • Use the attached black tab to pull the display data cable connector straight away from the logic board.

    I found this to be the most frustrating thing to remove out of everything under the hood. I had to have my wife use her skinny, smaller fingers to jimmy it up, but the tape kept pulling up and separating from the connector. I was worried that I was pulling in the wrong direction (what do I know about logic boards?) and that the tab was going to come off as it is slick tape. She eventually got it, but she did have to use some force. If you don't have a set of skinny fingers, just be patient and use a little force. I think the instructions should tell you to pull straight UP on the black tab, rather than 'away from the logic board', for those of us that don't really understand the technical components/guts of a computer. Honestly, my wife knows less than I do, but she could have done this as easily as me.

    • Remove the eight T8 Torx screws securing the display panel to the rear case.

    • Lift the display panel from its left edge and rotate it toward the right edge of the iMac.

    Some extra tools I found to be invaluable in this whole process was canned air (used for keyboards and office dust), a microfiber cloth (preferably the one that came with your iMac if you still have it, but you can get these almost anywhere these days)and one of those soft foam monitor covers to put over the monitor while your friend is holding it up (a soft sheet or towel might work too). If your computer is a few years old like mine, there will be a considerable amount of dust that you will want to clear out (and will fly everywhere anyway). Once you cleared that out and replace the hard drive, wait until you've got the bezel and screws back on before using the canned air and microfiber cloth to make sure all dust and lint is clear of the monitor. This is where the second person will come in handy again. They can wipe while you spray. Get your glass top with suction cups still attached ready and wipe that with the cloth and air as well. While your friend does one last wipe of the glass and then the monitor, put the glass on as soon as possible so no more lint or dust falls onto the monitor. I did this and the monitor looks as beautiful and clear as the day I bought the iMac. It is truly a brilliant and beautiful design by Apple and LG.

    In this step, as I lifted the display, there was also a small cord in the front, near the fan, that was connected from the display to the inside panel. As I lifted, it unplugged. Anyone know what this is and where it goes when I put it all back together? Pic of the cord I'm referring to: http://i68.tinypic.com/keubkg.jpg

    • With the display panel still lifted, disconnect the four inverter cables.

    • During reinstallation, place the four inverter cable connectors in voids between components attached to the rear panel so the display panel will sit flush on the edges of the rear case.

    • (combined into one plug in on the 24")

    • Be sure to keep track of the cables, as they do not have proprietary sockets. Mismatched cables can cause screen issues.

    I did a HD replacement on my 24 inch iMac. It's mostly the same, but it does not have disconnectable inverter cables. Instead, there's a single cable that can't be disconnected. It sits too tight to rotate the display to the degree that you can lean it against something, so the only way to get the job done was to call in an extra set of hands to hold the display while I took out the hard drive.

    Marijn - Yanıt

    I'm almost sure by HD you meant HDD (Hard disc drive).

    Charles Hess -

    As Marijn said, there are no disconnectable inverter cables on the 24" iMac, just a single thick cable in the middle of the back that is heavily taped with black electrical tape. I imagine you could remove that and retape, but it seems like it would be more trouble than it's worth. There is definitely enough clearance for someone else to hold the monitor up and away from the hard drive. For this reason, I would not attempt to replace the hard drive on a 24" without another person to help. The monitor is not heavy, and it doesn't take a ton of time to remove the old hard drive. It would also help if one of you has skinny fingers ;-).

    Len - Yanıt

    Mark them before unplugging so you can reconnect them the right way when reinstalling!

    Dirk Simons - Yanıt

    On the 24" iMac, the single inverter cable can be easily disconnected from the back of the LCD panel after peeling back some of the thin black plastic film. It is not necessary to disconnect the panel if you have four hands, but sure makes the job easier.

    Geoff Shepherd - Yanıt

    sh******t I didn't mark the connectors and now I don't know how to plug them back. I'm doomed ! any trick to identify them ?

    cheers

    Julien Waroux - Yanıt

    Same here. What did you do? Try them both ways?

    Leon Wagner -

    hold the led with my head lmao

    b12amyh - Yanıt

    You have to mark the Cables so you can reassembly them in the right order.

    If you don't (like me) and go with trial and error you probably have a purple screen.

    If so, you might also have been close to a heartattack… do a PRAM Reset by pressing command-Option-P-R at restart.

    My iMac works fine now.

    Pascal - Yanıt

    OMG, Thank you for this comment. I didn't initially label the inverter cables either. I did a fan replacement and RAM upgrade on a friends 20" iMac and had staticy, purplish screen. I thought I'd damaged the LCD. The PRAM reset fixed the display issue. Thank you so much for this!!!

    gwarren -

    I have the purple screen. :( I tried the pram reset. Do I switch the inverter cable connectors first?

    jaredrod - Yanıt

    I didn't mark the cables either, and now have a gray screen. I´m doing trial and error but can't get it to work. Any tips on finding the right cables?

    Marcus Svensson - Yanıt

    There should be a “star” at the beginning of this step to mark the wires as they are not color coded. Wish I read these comments first. Hope it works when I turn it on,

    John Rosati - Yanıt

    Of course I mismatched a pair and colors were distorted. After a trial by error switch of cables it worked perfect. MAKE SURE YOU LABEL THE CABLES AS NOT TO MIX THEM UP.
