危险

简介

在开始工作之前 拔掉电脑电源,按住电源键10秒来为电源电容放电。

小心 请勿触摸电源处的任何电容和引线以及暴露的焊点

只可抓板的边缘位置

  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

    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.

      • 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…..

    • 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.

    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!

    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

    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..

    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.

    Two notes here:  If you are using OWC’s Thermal Sensor HDD Upgrade Cable, be sure to tuck the cable under the hard drive slightly.  You cannot allow the connector to sit near the top edge since this will not allow the monitor to sit flush with the chassis when it is reattached.  Additionally, the SATA connector does not seem to fit together as snuggly as when it was connect to the HDD, so tape or a plastic cable tie to keep the connection tight may be good insurance to prevent it from coming loose.

    If you are planning on dual booting with Windows 10, the Windows 10 installed failed when the SSD and HDD were both connected at the same time.  I had to disconnect the HDD until Windows 10 was installed.  Note: I did a fresh install on a new SSD not configured as a fusion drive.  If you are planning on doing this as well, use packing tape (or something similar) to hold the monitor in place until after installing the OSs.  Then reconnect the HDD and apply the adhesive to the monitor for a permanent seal.  Good Luck!

    Gregorio Alvarado Sahli -

    Full removal of the speaker is unnecessary - just very carefully unplug the two-conductor power button cable, which is routed through the groove along the edge of the speaker enclosure. Next, unfasten the two large torx screws holding the speaker enclosure to the chassis. Now you can easily scoot the speaker away from the drive mount - move it over just enough to reach the drive mount’s 2 torx fasteners beneath the edge of the speaker (a CM or two). There’s now enough room to easily remove and replace the drive assembly .

This just ended my love affair with Apple. This is the second PSU fault on 2 machines over a 5 year period and in both cases, the machines have (or, in this case, will have to) return to Apple for repair. I'm thankful that Linux has finally reached the point where I can use it daily without having to worry too much. I have a fairly heavy investment in Apple software but that's just going to have to wait until the company makes user-serviceable machines again... right now, Hackintosh looks the way to go for that. I can't abide having a machine that I can't reasonably service with commonly available parts.
