更换您 2012 晚期 27" iMac的左扬声器。

  1. 从靠近电源按钮的左边显示屏,在显示屏和后盖的缝隙中插入iMac打开工具。 iMac打开工具的托盘会避免你把工具深入太深。如果你使用不同的工具,不要插过3/8英寸。操作不当可能破坏显示屏和破坏天线。 iMac打开工具的托盘会避免你把工具深入太深。如果你使用不同的工具,不要插过3/8英寸。操作不当可能破坏显示屏和破坏天线。

    Would a heat gun make this step easier? Or damage the iMac?

    Clark Green - 回复

    A heat gun wouldn’t help you here as you still need to cut though the adhesive. You also risk damaging the display with the excessive heat.

    Dan -

    Removing the original adhesive is easier than removing newly applied adhesive (e.g., if you have to reopen iMac).  If you should happen to need to reopen the iMac, please use extreme caution and highly consider my suggestions below.

    When using the pizza cutter tool, do the first few steps in reverse starting with step 8.  Starting on the left side is better since this is where the adhesive is narrowest.  The right side has two antennas and the top right has one, see the pictures for step 18-21, they are the brass colored metal rectangles near the edges.  The adhesive on these pieces are wider and therefore have more holding power.  The thickness of the pizza cutter tool is enough to crack the glass.

    Walter Hayden - 回复

    Continuing from my previous comment.  To remove the adhesive on the right side you’ll need to create a very slight gap to give the pizza cutter some more room.  Do this by cutting the adhesive on the left side up and around to the camera.  Before attempting to cut the right side. Carefully slide the plastic cards (I purchased two sets) to ensure the adhesive on the left top and side is completely free.  Now slowly move towards the right side.  After every inch or two of removing new adhesive, slide the card over to create this slight gap.  Be careful to not move the card too close to where the adhesive has not been cut.  You want to create a very slight gap without creating too much pressure.  Use extra caution with approaching the areas where the antenna are since the adhesive is stronger here and will need some additional cutting.  Follow this approach all the way around the right side.  Be careful to not create too much pressure at any one time.  Good Luck!.

    Walter Hayden - 回复

    I can confirm with Walter - trying to remove freshly applied adhesive is WAAAAY harder! My pizza cutter didn’t work correctly (the circle became a rectangle!) and I ended up with a small crack on the left of my screen. Dang it!

    Benon Koebsch -

    I would highly, highly, highly recommend AGAINST doing this at home. I followed these instructions to a T, and still somehow managed to have the screen not be able to turn on after the hard drive replacement. Then, once you’ve opened your Mac yourself, Apple will refuse to fix anything on the computer, and even other third party, Apple-authorized repair facility will refuse to repair it for you, and you will have to locate a non-authorized Apple repair facility. There, I am having to pay ~$600 to fix things that got screwed up, even though I followed the instructions here to a T, step by step, and did everything slowly and methodically.

    Beware, if you’ve never done this before, that be locked out of ever being able to use an Apple repair facility, or Apple-authorized repair facility, if you mess things up here now.

    I performed this on a Late 2015 iMac and there weren’t any significant differences to these steps, but I did find the repair to be nerve-wracking. My model cost nearly $3,000 and about 10 steps into this guide (which I did fully read ahead of time) I was thinking, “what have I got myself into?” But I didn’t rush and happily I’m typing this on my repaired iMac! I found a video from OWC that was more useful than the photos in this guide for certain steps: https://vimeo.com/139364064

    Don’t know if you are still around, but THANK YOU for posting this video! The video made it seem SO NOT SCARY and, in conjunction with the photos and comments and tips on this guide, was a lifesaver. Big thumbs up.

    Melissa Ortiz -

    First impressions so far: yes it can be a bit nerve wrecking if it is your first time doing this sort of thing and even with lots of experience with a 2011 model it’s still a bit unsettling haha (nervous laughter).

    What I recommend: use a guitar pick to start cutting the glue. You’ll need a bit of pressure so do just the tip.

    Once you’ve done the whole perimeter (minus bottom) do it again but now it should be easier to go deeper so go very slow and careful. Then get the old suction cups used to open older models and start lifting the display very carefully to see where it’s still glued and cut those as well.

    Then you should be done and now the real fun begins! :D

    Carlos Ferrari - 回复

    It’s ridiculous. Apple should pay for doing this. Like glue parts together to block a repair / make difficult. I smashed my iMac. FU Apple. Seriously, every product I owned had hardware issues. For example, bad solder joints. Never again Apple. I’m happy with Windows and in 2018 / 2019 there are many other manufacturers with high quality stuff. Apple is dying, if they do not change …

    Depple - 回复

    NOTE: I followed every step word for word, but the adhesive strips supplied are as bad as double sided tape. Within 48hours the screen had slipped off and cracked. Now I need to fork out for a new screen and try again.

    Not sure what to try next time with strips? Perhaps a bit of glue to help hold it??

    Hi @snappadoodle! The opening tool is included in the adhesive kit included in the tool list, but you can purchase it separately here.

    Sam Goldheart -

    After disconnecting the power cord and before cutting the panel adhesive, push and hold the power button for 10 seconds. This will discharge the power supply capacitors. In case you accidentally touch the solder joints on the board, you won't be shocked and drop the panel.

    Bottom line: This repair seems to have worked (so far no more intermittent shut-downs). Thanks iFixit!

    As a novice who fully expected to destroy the display or worse, I make the following recommendations: (1) Before you start, read the steps several (many) times; visualize doing them and imagine how things could go wrong; (2) Read all the comments—there were some really helpful tips—like simply displacing the left speaker rather than fully removing it; (3) Get the recommended tools*; and (4) take your time—if you start to feel frustrated—seriously, stop and take a calming breath. Time is your friend. Failure is not an option.

    *I would add a 3-prong parts puller to the tool list—it’s great for pulling and starting loose screws so you don’t drop them down into the chassis like I did. It’s also great for retrieving the screws you’ve dropped into the chassis.

    Hi brad, what exactly did you repair to stop the shutdowns? I’m having the same issue

    Brad Bauknecht -

    Just completed the Core i5 to i7 CPU upgrade and can strongly recommend getting the “pizza tool” to cut the display adhesive. It worked flawlessly and was done in less than 5 minutes. No inadvertent cables cut. No display problems.

    Thank you very much for the instructive tutorial. I just successfully replaced the hard drive on my 2012 iMac 27. I used a disposable surgical scalpel 15 blade, and locked the blade extending 9 mm from the scalpel shaft using office tape. I used regular double sided tape to reattach the screen. I cut the strips using the scalpel. I have no previous computer experience and this is the first time I replaced a computer part. This was easy and fun.

    You are very lucky! I’ve had three systems come in which someone did the exact same thing! All three cut the display ribbon cables. Please don’t use surgical knifes or any other knife! Use the proper tool the special pizza cutter wheel designed for the task.

    You likely spent more on the knifes than what the wheel cost with the correct tapes. You make the next time doubly hard to open not using the correct tapes! Hows the built in microphone? You may have messed it up.

    Gerry - 回复

    In my experience the cutter also worked very well for cutting the original adhesive. Unfortunately when I was reinstalling the display with the new adhesive strips, somehow the display power connector came loose. I had to open the display a second time and the cutter was not as effective against the new adhesive. I managed to break the cutter tool plastic wheel and cause a few small cracks in the edge of the displays glass as I worked! Be careful and go slowly!

    azaadkb - 回复

    The cutting tool worked great until I accidentally twisted it a bit while rounding a corner. A chunk of the wheel snapped off, making the rest of the job quite a bit more challenging. Just make sure you are keeping the tool directly parallel with the screen.

    BARRY RODRIGUEZ - 回复

    I concur, opening the screen a 2nd time is considerably more difficult because the adhesive strips are thinner than the original, which makes getting the cutting tool inserted much more difficult….as a result unknowingly I elongated a small crack to a much longer crack and somehow, the LCD now has a wide grey strip from top to bottom….The first time opening was easy, second time resulted in a ruined screen.. The cost of. a replacement LCD is the same has replacing the entire computer….I would recommend anyone attempting to remove the screen for any reason, do not use the aftermarket adhesive strips if you ever intend to open it up; again, or cut the strips much shorter, or possibly use a few pieces of scotch tape or similar to hold the screen in place….since the screen tilts back, this should not be a problem…Good luck…

    I actually DESTROYED my display (black vertical strips) by pushing the card in a bit TOO DEEP. So it is REALLY important to insert the card only a bit (1-2mm) more than the cutter wheel, in particular at the top side, where many flat cables connect the panel with the PCB. These can be damaged very easily!

    I broke one too. And even if you think you did it correctly, you’ll not be able to see where you might have gone too far. You would think it’s very protected behind that metal plate, but no.

I mean replacing a hardrive that is very likely to fail over the course of time, or even a simple desire to upgrade to an ssd!.

    I’m thinking I might just use vinyl tape to keep the screen in place for at least a little while after an upgrade. The extra strength of the replacement tape sounds scary.

    Art Hackett - 回复

    I wrapped two layers of vinyl electrical tape around the short side of an old gift card 3/8” from the edge. This “stop" prevented the card from going in too far. The card really helps to break the panel free.

    Umm.. I’m not sure that I’d recommend using a repurposed credit card to open the display - I found that using the “pizza tool” to cut the old adhesive then using a pair of suction cups to gently pull the display up worked perfectly well.

    My children tend to collect cards like this from hotels, Disneyland, old IDs, iTunes cards, gift cards etc. They came in handy for this step. After wedging in the first card into the left corner, I wedged the left corner, then added cards along the bottom edge. Finally I continued to push in additional cards to existing cards and found that this created a smooth even pressure along the display top. At 2-3 card-thickness the last of the adhesive let go, gentle as a baby.

    After finishing my hard drive replacement I reconnected these connectors to test my display before using new adhesive. Everything was working beautifully. But then when I applied the new adhesive and went to seal the display on for good - the display power cable somehow became disconnected! I had to reopen the Mac for a second time which was far more difficult with new adhesive. When reinstalling double and triple check that the cables are securely inserted before the final seal. Sounds obvious but it’s quite the annoyance if something goes wrong at this point.

    Interesting comments.. personally, I didn’t find the cables particularly difficult to detach and reattach. You do have to be patient and gentle. Personally, I found that a rolled up beach towel gently wedged between the unit and back of the display helped keep the glass up. Also, a small flashlight can be helpful to see the cables and connectors if you’re lighting isn’t perfect.

    John Fisk - 回复

    I’d agree to John - not overly difficult. My workaround was to prep the screen for re-installation and then place it in front of the standing machine. The cables are long and flexible enough to be put in place even in this state. You can easily attach the cables and continue with fixing the screen to the housing.

    stefan - 回复

    I would not recommend doing this step as pictured. The cable you are removing has little tabs on the wide side that can be depressed inwards towards the center of the connector, releasing the cable. If you just grab the cable as pictured and yank it out, without depressing the side tabs, you are likely to damage something. Don’t pull on the wires, use your fingernails at the connector to squeeze the very small little tabs inward to release the cable from the connector.

    First: During reassembly, I highly recommend you connect these cables and do a test boot BEFORE you remove the protective tape on the adhesive strips. That way you can fix any issues(like a damaged cable) if something is not right and you have not re-glued the screen back down which will cause a problem. If you have a second person and everything is working after test boot, you can just leave the cables connected, lift the bottom of the screen and have 2nd person pull the protective tape on the adhesive strips and you can set the screen in place. Second I damaged the video data cable during reassembly on my late 2015 iMac- I did not get the connector straight and I damaged the wires on the cable. I recommend you have someone else hold the screen while you attach the cables - they are fragile. Luckily, the data cable was easily replaced for only about $20. If you must do this by yourself, just be careful I highly recommend have 2 people at this step during reassembly.

    At least on my “late 2013” model, the smaller display cable connector has tiny, tiny clips on the outside edges. These must be squeezed to unlatch it. Don't pull on the cable itself or the wires can be pulled out. Even with my small fingers, it was hard to grip the clips. When reconnecting, the connector will lightly snap into place.

    I managed this step without any problems, but I had my wife hold the screen up while I disconnected/connected the cables. I STRONGLY encourage another pair of hands here so you can focus your full attention on being ultra careful with the cables.

    On the 2015 there are 2 cables.

    1. Once the display is loose use the Mac foam block sold from Ifixit to keep the display from rocking to hold open the glass

    2. Blow out dust with canned air

    3. Get a flash light and small flat edged screw driver

    4. Use the screw driver to slow pry loose the connector from the socket by gently inserting it in the gap on the left and then on the right slowly easing the connector from the socket towards the top of the glass

    5. The more center connector has a pull tape and a wire loop. Lift pull tape and the wire loop will raise up.

    6. Pull the wire loop towards the top of the glass to slide out the connector from its socket

    Have a late 2013 model and went to do the SSD upgrade. When going to remove the display we cracked the bottom left corner of the glass (just the glass frame part - not part of the screen that displays anything). We were also having difficulty putting re-attaching the display flex cable. Whenever we finally went to test it before re-sealing the screen back on with new adhesive it would sound like it is turning on as it makes boot-up noises and the fans start running, but the screen would just remain black. Just wondering if the crack in the bottom left-hand side of the glass/display would have damaged a part of the display assembly or if it would be more likely that we just damaged the display flex cable (which can be replaced for $26)?

    I’ve completed the upgrade to SSD, but while restarting my screen remains black. As if no connected.

    I assume I broke the sensitive connector.

    Yep, I cracked the lower corner of the display as well. I failed to work the adhesive enough to loosen it sufficiently. Be careful, I just had to buy my customer another screen!

    There seems to be missing a step or two. As I was removing the old display, there are two wires that need to get transferred to the new replacement display. There is not note about these two wires located at the top of the display. The 1.128-inch ribbon cable and then this other 4-inch long, two-wire cable that goes to a very small circuit board that is 1/4 by 3/8 of an inch and seems to be adhered to the panel.I have not been able to get this cable off the old display. There is a port for it on the replacement display.

    Note: When ordering this screen, and plastic cards as noted tools, ifixit.com did not list the pizza cutter or the new replacement adhesive strips. So now I’m not sure how to get the new one on and secure.

    Todd Derek - 回复

    The adhesive strip along the bottom is designed with a pull tab on each outer end. Rather than lever and pull the screen simply carefully pull the tab which removes that half of the lower adhesive strip and frees up the screen.

    Andrew Stephens - 回复

    Niemals den unteren Klebestreifen mit einem scharfen Gegenstand wie Rasierklinge oder so versuchen zu trennen, davon geht die Beschichtung des Displays kaputt und man hat hässliche Streifen unten hinter dem Glas. Stattdessen lieber versuchen, das Display nach oben zu klappen und abzuziehen.

    Bas ti - 回复

    translation from Bas Ti because this is very important:

    Never try to separate the bottom adhesive strip with a sharp object such as a razor blade or something, the coating on the display will break and you will have ugly strips at the bottom behind the glass. Instead, try to flip up and pull off the display.

    Kurt Grootjans - 回复

    If you are just replacing the hard drive, I have found that it is quite possible to do while leaving the screen connected, making the process much easier. The amount you need to tilt the screen to access the little pull tabs at the bottom to release the screen is also sufficient to access the drive. I remove the drive while the iMac is upright. I also heat up the bottom of the screen to soften the glue and to help with the possibility of the glass cracking while doing this step.

    Would have been helpful to box the same red area when using the plastic card to separate the glue. Since the red blocked picture is inverted, if someone doesn't pay close attention it may not be obvious that the area of concern is at the right top of the graphic pictures in which the plastic card use is being demonstrated..

    What is the twisted wire taped to the back of the display that can bee seen in the upper right of the first two pictures? I have an 27” iMac without a screen an my replacement does not have this wire. I think it is a temperature sensor but do not know where it connects to.

Bien calé et assuré l’écran n’a pas bougé et j’ai pu changer mon disque dur facilement. Le grand avantage et d’avoir l’écran toute suite juste quand on le recolle par la suite.

    Well, I of course touched a soldering point in the red area as my hand slipped. I heard and felt a tiny “click” and after replacing the HDD with SSD etc I can not power the iMac up anymore.
