iMac Intel 21.5" EMC 2638 显示屏更换件

你所需要的

  1. iMac Intel 21.5" EMC 2638 显示屏更换件, 显示屏组件: 步骤 1 中的图像 1,1
    在这个步骤中使用的工具:
    iMac Intel 21.5" Cardboard Service Wedge
    $4.99
    购买
    • 如果铰链可以自由活动,iMac将会失去平衡,维修很难进行。有了 iMac 维修支撑盒,维修操作将会更加丝滑,但是没有这玩意儿也行。

    • 如果你使用的是 iFixit 硬纸板维修楔,请按照 这些组装说明 将其组装在一起。

    • 在开始你的iMac的任何维修操作之前:拔掉电源线,按住电源按钮至少十秒钟,以释放电源的电容器。

    • 特别注意!不要触摸电源线上的电容器引线或任何外露焊点,只能触摸电路板边缘。

    The wedge is an extremely tight fit for this model. I was worried that the amount of force needed to use it as shown might damage the stand, so I used it with the long side down instead. It worked fine that way and didn’t need anywhere near as much force to insert.

    Here are a couple tips from me:

    1) Expose the adhesive to extreme temperatures. I did this by transporting my iMac in my car, screen-down on a piece of cardboard on a cold February morning (in Chicago). When I went to pick up the iMac, the screen practically fell off the chassis. I would have been distraught by this if I hadn’t already planned this replacement. So it was a happy accident.

    2) Remember to expell the residual power from the power supply by pushing the power button while the iMac is unplugged. This does NOT guarantee it’s safe to touch, but when I accidentally brushed the solder and exposed capacitors, I didn’t get shocked.

    jerrid_foiles - 回复

    Instead of using the wedge, I placed the iMac faced up with the top side (web cam) facing me while I ran the pizza roller around. It worked out great!

    Sam Fung - 回复

    “All iMacs also come with a traditional hard drive” mine doesn’t!! it’s HDD bay is completely empty, no SATA cable or anything. I guess I’ll have to upgrade the PCIe SSD instead.

    Chris Hughes - 回复

    There is no replacement glass for this model, it is part of the LCD and impossible to remove or replace- the entire LCD has to be replaced unfortunately if the glass is cracked or damaged. You will have to Google search for a replacement. Also be careful with some of the lock tight tork screws as I broke one of my screw mounts taking one out.

    Phil Tesone - 回复

    I used this service wedge but also found it a very tight fit. The same stabilization can be achieved by using a big rolled up towel.

    Ernst - 回复

    While this is a good instruction guide, I recommend to also look at OWC’s instruction video about drive installation, before starting the exercise. Those install videos are very detailed and useful.

    Ernst - 回复

    Main advice: TAKE YOUR TIME with the pizza roller.

    Make several passes, until you really feel like there's no more sticker in the way. Stay away from the camera though (approx. 1inch / 2.5cm on both sides). This will reduce the work left with the plastic card. Adhesive is really on the edge of the screen so there is absolutely no need to go any further than the recommended 1cm / 3/8inch depth.

    Where are the sensitive parts?

    Facing your iMac, imagine you're looking at a watch. There are antennas on 1, 2 and 4 o'clock. Do not insert any metal piece there (nor anywhere else, btw). Other than that AND the screen cables underneath the camera, not much danger.

    • 从显示屏的左边开始,就是靠近电源按钮的一侧。将 iMac 开屏工具插入玻璃面板和后部外壳之间的缝隙中。

    • 在 iMac开屏工具中心的支点会防止你将轮子插太深。如果使用别的没有防呆设计的工具,插入请不要超过0.95厘米。否则,您可能会切断天线电缆并造成严重损坏。

    Don’t get too worried about starting exactly where the picture says. The glue is stronger in some parts so just start wherever is easier and then work slowly and patiently around in the direction shown.

    As this guide doesn’t cover replacing the adhesive strips, I found referring to the following was useful (noting that it’s not for the same model of iMac, so the modification they mention wasn’t necessary): iMac Intel 21.5" EMC 2544 胶条更换

    It is very easy to crack the glass in front of the LCD during this step. I used the guitar pick, maybe it was too thick… crack is just on the frame but anyway it is disappointing :(

    Nikolay - 回复

    This part of the exercise should be done with extreme patience. I took my sweet time with the opening tool, rolling it through the entire panel and enclosure gap over and over again, until I was very sure no parts were sticking together anymore. And when I thought I was I done, I decided to do it over again.

    Ernst - 回复

    You can "warm up" the adhesive before try to cut it with the tool using a hair dryer. Heat the edges for about a minute, keep moving it so you don't cause stress in the glass. Also the above note.. use the tool and then the cards. Do not use a guitar pick or other objects as the thickness will cause you to break the front glass, which is a bonded part of the display (expensive).

    • 像用披萨刀一样用这个工具——沿着缝隙一直滚动就行,里面的泡沫双面胶就会被割开了。

    • 这个工具一定要用往前推的,不要往回拉,否则轮子会掉。

    • 按照如上所述方法,沿着显示器的左侧使用这个工具。

    Moreau - 回复

    If re-opening a screen that was opened and re-attached using iFixit’s adhesive strips, I would strongly recommend heating it first with an iOpener, heat gun or hair dryer. 20 minutes after attaching with the iFixit adhesive I tried to open it again with the pizza slicer to fix something and cracked the screen on the left-hand side.

    • 沿着显示器的顶部继续。

    • 你可能需要重复上述操作数次,以确保尽可能地将胶分开。

    In this step can I cut along the display without make any damage to the front camera?

    arisnordico - 回复

    Hi! Actually - there is no need to cut the tape around the camera area - there is no tape to cut at all! And so, the way go is easy - just pass 10 mm to the left and to the right from camera and start cutting!

    P.S. Just did the whole procedure to replace a RAM and to add SSD on PSIe an hour ago! Seems to be different reading the instructions... you know - 2/10 and so on. But it's really not that hard, trust me. I'll give it 5/10.

    P.P.S. By the way there is one trick to pass the difficult steps. Any action which requires pulling smth (motherboard, speaker, power supply unit) from the narrow crack (or should i say - slit?) at the bottom of your Imac is really not so easy.

    And the trick is to first remove a thin metal stripe with some kind of insulation on it which held by 5 small (very small!!) screws at the bottom of your Imac. After you done it - it's easy to pull everything! Pay attention to the fact that one of this 5 screws at the center are more shortly than others.

    You can add a SATA SSD if you already have a PCIe SSD Factory?

    kaserlik - 回复

    If you're changing cracked EMC 2638 display to new assembly, there's two more steps:

    Step 24: Use the tip of a spudger to flip up the metal retaining bracket on the display data cable.

    Carefully pull the display data cable from its socket on the display assembly.

    Step 25: Use the tip of a spudger to unplug bracket of the thermal sensor small cable near display data cable.

    Carefully remove scotch tape covering thermal sensor. Using iSesamo or flat tip of the spudger carefully peel the thermal sensor away.

    pzhivulin - 回复

    omg - forgot to switch the termal sensor from the old display...

    now fan runs like crazy...

    Andrei Balotescu -

    The key thing is to never put any force on the opening tool when working through the tape. Just roll it back and forth with ease.

    • 此时,你需要在整个显示器周围重复数次切胶操作,以确保可以去除更多的胶。

    Yes, do it many times to loosen the adhesive.

    Noah Ralston - 回复

    Would be good data to show the 3 areas (wifi antennas where the "tape" is larger and covers them. The rest of the "tape" is 1.4" and easy. Also after removing the display, be sure to remove the old "tape" from both the display and the rubber parts of the case. Use the spudger to start an end and it should pull off easily. Careful on the baackside of the display as you can scratch off the black paint/covering.

    • 虽然开屏工具切除了大部分的胶,但显示屏的些许的胶还是会黏在外壳。塑料卡是最后分离粘合剂的必要工具。

    • 让 iMac 躺在桌面上,屏幕朝天。

    • 从 iMac 的右上角开始,往屏幕和后壳之间插一张塑料卡。

    • 请注意不要将塑料卡插入超过0.95厘米,否则可能会损坏内部组件。

    this step is extremely important NOT to stick in the cards too far….. doing so, you risk a 600 euro replacement as I experienced………

    • 将卡片往前滑至机身顶端中间,以去除显示器右上角剩余的黏胶。

    • 请确定避开 iSight 摄像头,否则摄像头可能会损坏。

    You don't need to do it like this, simply open the iMac bendidng the LCD completely and use the pizza cutter to remove the adhesive.

    • 如图所示,将两张塑料卡片插入角落附近,轻轻地往侧边扭动来增加显示屏跟主机壳的间隙。

    • 如果有部分的黏胶而无法完全分离的时候,停止扭转,使用其中一张卡片来切开剩余的黏胶。

    • 开始将显示屏上部从框架拉起。

    • 只需抬起显示屏几英寸——因为显示屏的数据线和电源线仍然和主板相连。

    bstaud - The display power cable has two squeezable levers on each end of the cable’s width.

    Squeeze the left lever with your thumb while you simultaneously squeeze the right lever with your

    index finger, and gently pull the cable straight back and out, and the cable comes out very easily.

    Ted Horodynsky - 回复

    When reassembling, make sure you get a “click” confirmation that both the levers have locked AND the pins have seated on this connector. I was treated to a black screen upon startup, and had to re-cut my newly installed adhesive strips to get back in to firm up this connection. Better would be power up with the bottom adhesive in place, screen resting in place and held on top with blue painter tape to confirm connections, THEN pull off screen-side adhesive tape covers for final re-bonding.

    • 使用撬棒尖端撬起显示屏数据线上的金属固定盖。

    • 小心地将显示数据线从主板上的插座中拔出。

    • 确保将显示屏数据线接口从插座中直接拔出。

    • 请务必小心,不要触摸电容器引线或电源背面任何裸露的焊点(红色框内)。

    • 抓住底部边缘显示屏胶带之一末端的小拉片,然后将胶带向 iMac 顶部,将其除去。

    • 对另一条胶带重复此步骤并将其移除。

    • 如果任一胶带在移除之前断裂,请使用塑料卡切掉剩余的胶带。

    Cutting through this extra adhesive on the bottom took a bit more effort than the step and picture implied (to me). Unlike the other edges, here don't be afraid to really push the card in there to break the seal, there's nothing behind that adhesive that is breakable.

    phil - 回复

    cutting through the adhesive is unnecessary if it's not been opened before (outside of an apple store) there will be a tab at the end of each VHB strip that you can use to simply pull the vhb strips off.

    Rory McKenna - 回复

    YES, exactly the same here. more but more simple.

    Lucio Alves -

    To save a few steps and a bit of time, if you have a helper, they can hold the display at a 90° angle while you unscrew the brackets and remove/replace the hard drive rather than remove the display entirely. Also reduces the likelihood of damaging the display as you remove and handle it.

    marty - 回复

    The proper way to remove the display according to the Macintosh tech manual and videos is as Rory McKenna and Lucio Alves have learned is to pull the tab at the end of each VHB strip until it is off.
