简介

音箱听起来怪怪的?更换新的扬声器来恢复立体声。

在开始工作前: 拔下电脑电源,然后按住电源键10秒来为电源上的电容放电。

小心 切勿触摸在电源上的电容、引线以及金属触点。

  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。
    • 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。

    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!.

    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

  2. 就像切披萨一样—在缝隙里划过屏幕,这会切除掉粘在中间的泡沫粘合剂。

    • 一定要推着转盘的后面让转盘旋转,如果你是拉的,转盘可能会掉出托盘。

    • 在左方划开显示屏。

    I found the 'pizza cutter' surprisingly smooth at cutting through four-year-old adhesive.

    Gerry - 回复

    • 继续用工具划过左上角。

    添加评论

    • 从左上方开始,沿边切除粘合剂。

    The pizza cutter will sink in all the way to the tool handle when the adhesive is full cut, but don’t feel you have to do this in one motion. Some parts cut easier and some require a lot (like 20x) of gentle back and forth.

    Anthony Zimmerman - 回复

    • 划过上方的屏幕。

    • 你也许要多划几次,大约3-4次,确保大多数粘合剂已经分离了。

    添加评论

    • 沿着缝隙划到显示屏右上角。

    添加评论

    • 转一下,让轮子沿着向下方向。

    添加评论

    • 把打开显示屏的工具推到显示器右边的底部。

    • 此时,您会希望在整个显示器周围使用该工具,以确保尽可能减少粘结。

    添加评论

    • 当打开显示屏的工具做了大部分工作之后,显示器仍然会轻微地粘附在外壳上。用一张塑料卡就可以把这种胶粘剂移除。

    • 将iMac屏幕朝上放在桌面上。

    • 从iMac的右上角开始,在显示屏和外壳之间插入一张塑料卡。

      • 小心不要插入超过3 / 8英寸,否则会损坏内部组件。

    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!

    Peter Fischer - 回复

    Same thing with me…. Pushed cards to far…. new panel needed…€600…..

    i think ifixit needs to place a bigger caveat, as I have missed it the first time

    Edgar Broekema - 回复

    i successfully upgraded two imacs. one opened with ifixit pizza knife and another with a regular paper knife. however, when i had to open the first one once again i broke its screen glass. it seems ifixit adhesive strips are too strong. next time i’ll try to use heater to weaken glue tension.

    • 轻轻移动塑料卡,打开显示屏与外壳之间的空间。

    • 慢慢地移动,小心不要给显示器的压力太大,你只需要大约1 / 4英寸。

    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.

    • 在碰到iSight摄像头前一定要停止切割,否则你可能会损坏它。

    • 将卡片向显示屏的中心滑动,以减少剩余的黏合剂。

    was denn jetzt? Vor der Kamera aufhören, oder in Richtung Bildschirmmitte schieben, um DEN REST zu entfernen? Wenn ich vor der Kamera aufhöre, kann ich nicht alles an Kleber entfernen.

    Julia S. - 回复

    • 把这张卡放在显示屏的边角处,让它留在那里,以防止粘结剂重新粘合。

    添加评论

    • 将第二张卡插入显示屏另一个边角处和外壳之间的空隙。

    添加评论

    • 轻轻抬起卡片,稍微增加显示屏与外壳之间的间隙。

    • 与另一边一样,慢慢地移动,让胶粘剂破裂,注意不要过度按压玻璃。

    添加评论

    • 把塑料卡滑到中心,再一次停在iSight相机前。

    添加评论

    • 将卡片插入显示屏的另一个边角处。

    添加评论

    • 只把显示屏抬起几英寸——它仍然是通过数据和电力电缆连接到iMac上的。

    • 将卡片插入到边角附近,轻轻地扭转卡片,以增加显示屏与外壳之间的距离。

    • 如果有任何部分看起来粘在一起,并且不会分开,那就停止扭转卡片,用其中一张卡片在问题区域中切下胶粘剂。

    • 开始从外壳中抬起显示屏的顶部。

    I would recommend using suction cups at this stage to lift the display.

    Marco De Palma - 回复

    • 用一只手握住显示器的同时,用另一只手拔下显示电源线

      • 把显示器提升到足够方便的高度,但不要太高,电缆还是连接在逻辑板上的(电缆约长8英寸)

    Mark all cable connectors with a spot of white correction fluid before removal. This will remove the risk, when reinserting them later, of getting them the wrong way round. Yes - I know they will only plug in one way round, but it does make life easier if you are not in perfect lighting!

    At this step, if you mess up anything with these 2 cables, especially when plugging them back in, even if you think you’re following the instructions here to a T, then you’re screwed.

    The display cable, the wider one, has a lock on it , usually a plastic tape lift tab to release it, once thats flipped it should come out fairly easily, if your experiencing resistance and the cable isn’t coming out then check for this lock/latch, the power cable just pulls out, just don’t rush it everything should go fine, fairly easy to do with the end result a working iMac

    • 打开覆盖在显示数据电缆上的金属盖片

    • 断开显示数据电缆

      • 这是一种很容易被打破的微妙关系。确保将显示数据电缆连接器直接从其插座中拉出,并拉向iMac的顶部

    I replaced HDD to SSD and assembled parts again. When I boot up the iMac, I found black lines on display (looks partly not broken).

    I searched Internet, and some says graphic card problem, but I didn't touch anything but cable to lift up.

    Could the damaged display data cable cause this situation? I hope I could fix this by just replacing the cables..

    chansung park - 回复

    Sorry, Black lines is a damaged display assembly ;-{ In the process of removing it you either pushed the tool into deep or you torqued the glass severing the tiny wire traces.

    Dan -

    Same trouble here, is it cable trouble or connector trouble?

    Sorry damaged display

    Dan -

    I think whenever words like "...is a delicate connection that can be broken. Be sure to pull the [cable in a certain direction] ANYTIME.... It is worth either a closeup or 2, maybe one with annotations or insertion directions and maybe a motion direction arrow with the something like and 'X' char or a circle division slash over the wrong one.

    Can anybody upload an image of how the display can get damaged from removing it? I find it hard to believe (though I’m reading the horror stories here) that a whole display can get damaged. Especially when many of us were following to a T and being VERY CAREFUL.

    Thanks.

    • 将显示器提升到接近垂直的位置

    • 此时,显示屏底部仍有一块胶粘剂,可以像铰链一样将显示器固定在外壳上。你可以通过几次开合来将这种粘合剂弄松

    • 通过抓住外部边缘多次开合尽可能多地去除粘合剂,然后将其拉到需要的位置

    Thank you Stef, that's what i will do next time, i cracked the lower part of the screen went opening very slowly, that's probably why those "tabs are for !!

    Thanks Stef, this has saved me! Simple yet very effective.

    David Zemsky - 回复

    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!

    Peter Haigh - 回复

    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.

    • 如果需要的话,可以用一张塑料卡来切割底部粘合带的剩余部分

    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..

    Wizbang FL - 回复

    you don't need to cut the bottom part as the bottom tape is stuck on each side and you can easily pull it out

    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.
