はじめに

iMac内部のほとんどにアクセスするためのLCDを交換しましょう。

    • 作業を始める前に、iMacの電源を切り、画像のように本体を倒して、柔らかい表面上に載せてください。

    • ガラスパネルの上部コーナーの2箇所に吸盤カップを取り付けます。

    • iFixitが販売している吸盤カップを取り付けるには、まず吸盤カップの持ち手ハンドルをガラスパネルの表面に対して水平になるように上げてください。ガラスに吸盤カップを軽く装着して、もう一方のハンドルも平行になるように上げてください。

    • 吸盤カップがうまく装着しない場合は、ガラスパネルと吸盤カップを中性洗剤などで綺麗に拭き取ってください。

    Success replacing the stock ST31000528AS with a STBD3000100 (Dead 1TB to new 3TB, both Seagate). First try. Using another Mac and a quality Firewire 800 cable, I formatted it using Target Disk mode, 2 partitions (defaults, except I made the first one bigger than the second). To the second, smaller one, I copied a bootable Install OS X Mavericks partition. Tried to boot. It booted, and I installed; nary a glitch. (Running the Installer over Firewire would have been faster, but I didn't want to reboot this machine.)

    See part 2 below...

    (Part 2:)

    I SKIPPED steps 6, 7 AND 8! Instead, after doing Step 5, I noticed I then had enough room and cable length to access the screws in Step 11 if I lifted the LCD up an inch or so, rotated it about 20-30 degrees clockwise and moved it a couple inches toward the base, and put it down. After removing them (Step 11), I propped up the LCD (with a spare spudger) and had enough room to do Steps 12, 13, and 14 without much difficulty. Felt safer/less work and risk than not skipping steps 6-8. No risk of the damage Ersan and Michael caused performing Step 7!

    Matthew Elvey -

    I just edited that step to add a note about the shortcut.

    What the ???

    Geoff Wacker has REJECTED my edit: https://www.ifixit.com/Guide/history/ste...

    I wonder why. What's the deal, Geoff? I mean I'd understand if I suggested folks didn't need the suction cups, as that could cut into iFixit's income stream, but what's wrong with suggesting that a few steps aren't needed? It worked for me; the EMC 2389 I fixed is humming along with a new 3TB HD I installed while skipping those steps.

    Matthew Elvey -

    I did not have to remove a single cable! After undoing the torx screws from the sides, I was able to rotate the LCD out of the way enough to reach all the screws holding in the ODD bracket. One of them was a bit challenging to get to, but I never felt that I was risking the cables by leaving them connected. Also, it wasn't totally clear, but you have to actually remove the ODD itself from the ODD bracket - 4 torx screws. The SDD mounts into the hard drive enclosure, then the enclosure is screwed into the bracket. Those holes (enclosure <-> Bracket) did not line up correctly for me, and I had to go with only three of them connected in the end. Seems to work fine.

    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.

    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 - 返信

    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.

    Hello, I just need to replace a slightly cracked screen on my iMac. Where is it best to place the suction cups? Thanks in advance

    michelemiller0 - 返信

    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 have an odd question -- I want to remove the polarizer from the LCD. With some monitors this is trivial, others not so much. My question is whether it is bonded to the Liquid crystal, or whether it's loose, or cutting it with a razor blade would remove it. Obviously I'd like to know before I go to the trouble of dismantling the thing... Thanks. Paul

    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

    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.

    The metal near the screws is VERY magnetic. Honestly, the hardest and by far most frustrating step was trying to put these screws back in.

    seancourtney - 返信

    I ran into the same problem - easily the most frustrating part of this process. To help deal with it, I took a drinking straw, cut it to be about 2 inches long, and used it as a chute to guide the screw to the hole. Dropping the screw down the straw, it'd still stick to the side due to the magnets, but using my screwdriver, it was easy to push the screw down to where it needed to go, and the straw kept the screw from being pulled out of place by the magnets.

    josh -

    +1 for the straw tip. Worked a treat!

    osienna - 返信

    Hmm… yes, the magnets sucks - literally. But if you use a normal screwdriver or a bit, the screwdriver tip or the bit can be “loaded” by the magnets too. Just move the screwdriver (or bit) over one of the magnets and then “plug” the screw onto the screwdriver’s tip (or bit). It will be held by magnetic force. Just enough to move the screw vertically and very slowly into the whole.

    There are some special screwdriver on the market with “claws” to hold screws, but they are hard to find/to buy and expensive. I sometimes use superglue (a LITTLE) to temporary fasten the screw at the screwdrivers tip. This technique can be used with destroyed screw heads too to optimize adhesion.

    • アウターケースからディスプレイの上部端をわずかに持ち上げます。

    • あまり高く持ち上げすぎないでください。ディスプレイとロジックボードには数本のケーブルが接続されたままです。ケーブルが付いたままディスプレイアセンブリをひねったり、引っ張るとiMac本体にダメージを与えてしまいます。

    You can use one hand to hold the edge up while reaching with the other hand to disconnect cables. You may want to have a prop handy (like a small book) or an extra person to hold the edge up while you disconnect cables.

    Use the teardown guide for your iMac to familiarise yourself with the layout of everything before you dive in. I was able to get an idea of how much clearance there was once the display is unfixed from the frame, where the optical drive was relative to the base etc

    osienna - 返信

    The harddisk can be removed WITHOUT the next steps. The opening angle of the partially lifted LCD display gives enough room to untighten the two Torx T9 screws of the hard disk bracket, to unplug the two SATA connectors and to carefully lift out the harddisk. There is absolutely no need to dismantle the whole thing.

    All you need is a screwdriver which fits into the room. I’ve used the “Pro Tech Toolkit” from iFixit. The screwdriver with Torx T9 bit fits perfectly.

    The other “tool” you need is either someone who holds the LCD plate or the inner leftover of a kitchenroll, a scrunched paper, a small towel or similar which has to be stuffed between the logic boards and the LCD plate to keep the LCD at its lifted place (careful! don’t unplug any of the cables).

    I’ve opened and changed the harddisks of those 21,5 iMacs a dozen times with the help of the “Pro Tech Toolkit” and a kitchen roll.

    If i want to replace the HD with a SSD, can i still skip the next steps? I think i can’t because i need to change the termal censor, but i would like an other opinion please.

    The connector needs to be carefully pushed in parallel to the board with a surprising amount of pressure and the pull tab must be folded back. Not super fragile, but not strong either.
