    • Befestige je einen Heavy Duty Saugheber in den beiden oberen Ecken der Glasscheibe.

    • Um die Saugheber zu befestigen, platziere sie erst mit dem beweglichen Henkel parallel zur Glasscheibe (wie im zweiten Bild gezeigt).

    • Halte den Saugheber leicht an der Scheibe und hebe den beweglichen Henkel bis er parallel mit dem anderen ist (wie im dritten Bild gezeigt).

    • Wenn deine Saugheber sich nicht befestigen lassen, reinige sie und den Bildschirm mit einem angefeuchteten, fusselfreien Tuch. (Am besten verwende destilliertes Wasser und, wenn das nicht hilft, ein 50/50-Gemisch aus weißem Essig und destilliertem Wasser.)

    • Hebe die Glasscheibe nicht nur an den Saughebern hoch, da sie dir sonst runterfällt, wenn ein Saugheber sich löst.

    • Die Originalverpackung des iMacs ist ein guter Ort, um die Glasscheibe abzulegen. Andernfalls tut es auch eine weiche und ebene Fläche, zum Beispiel ein Handtuch auf einem Tisch.

    You can easily lift the glass panel off the magnets with only your fingernails (or something thin like a credit card or a guitar pick). No need to buy suction cups you will only use once.

    Nick Caron -

    Yes, you don't need the specific suction cups to remove the display cover - it's held on by magnets, and if you start at the center by the iSight you can work out to the edges and remove it. I had an iPhone screen suction cup around and it helped with balancing the screen when you pull it out fully, but by no ways is it required.

    Great guide and pretty straight forward the only thing that took me ages and I didn't manage to undo were the power btn cable (step 28) and the thermal sensor (step 25) Seemed like they were glued on! Very difficult to remove and obviously conscious so I didn't break anything!

    Eddie -

    Thanks!!! Worked excellently.

    I used a plunger (clean first ;-) to get the screen off, and http://exirion.net/ssdfanctrl/ for fan control.

    Then, i did not take out the whole display and left it in the hinges on the bottom side and held it up with two small cardboard boxes. Easy enough to disconnect the hdd then.

    I replaced with an ssd, put that into a ssd enclosure. Had to drill an extra hole in it to fasten the pins that hold it in place.

    Used Carbon Copy Cloner to make an image from the old hdd, with the sad connected via usb. Checked it of it booted via System Preferences > Startup Disk. It worked so the took the imac apart and replaced the disk. Booted, everything was working as always, only faster!

    I'm replacing my optical drive too. what exactly needs to be plugged into the SSD? I don't have the kit - as I am not sure one is required if I buy something like this: http://www.amazon.com/gp/product/B0056OB...

    Can you please advise? Can I do it with this piece, or do I need to get the entire bracket kit?

    Allen Borza -

    My display data cable forks, with a smaller section going up near the camera board. Where it forks, it is attached to the aluminum plate that attaches around the cpu board. I haven't seen any images that look similar, and I'm stumped at how to remove this second section of the cable. 2010 i7 build to order

    Awolf -

    Agree with the other comments here. Despite buying suction cups, not sure they were necessary as the screen removed very easily. A sat nav suction cup would do the job fine.

    Stuart Bloomfield -

    I can confirm that it is possible to remove the front glass using fingernails rather than suction cups. It isn’t easy, but if you try you should be able to pry off the glass.

    I did this twice: once at the beginning of the procedure and once again at the end, when I realized that a big pice of lint was trapped under the glass.

    gordonhamachi -

    Don’t use suction cups. totally unnecessary. screen pops off with fingernails.

    Kieran Hobbs -

    The reason for caution about suction cups tends to be making sure you don’t apply uneven pressure on the edges of the glass and crack it in the process of removal. I do agree however that some pretty small suction cups would do fine. These suction cups can be had at your local princess auto (Harbor freight) for a few bucks and are useful elsewhere as well. if you use your fingernails or other items just try and do it evenly :)

    Abirinder Brar -

    good duct tape or gaffer tape wrapped around your hands makes an excellent glass removal 'tool'. Even clear packing tape works a charm.

    Stu Blair -

    A great first step that minimizes that first gust of dust migration when the glass is lifted is to clean the glass, sides *and the back* before lifting the glass, and then lift SLOWLY. Most of that dust is already trapped inside and pulled up as the screen lifts, but with care you can keep it there (or gently vacuum out with a micro vac…).

    John -

    before starting any of this…there is a device that you can use that comes with the IFixit kit to format and either clone or restore your hard drive to the new drive…it will save you a lot of headaches..it is a SSD enclosure that you can plug into your existing computer …

    Tom Richter -

    Thanks for the instructions. Before doing this the first time, suggest to everyone, read through at least twice. This is the easiest step, as you’ll soon see. As for removing the glass, USE suction cups, either the ones the sell here, or others. DON’T skimp. Also wear gloves when handling the glass. Don’t take chances.

    ECJohansen -

    Duct tape works too!

    • Hebe die Glasscheibe rechtwinklig so weit vom Display weg, dass sich die metallenen Befestigungsstifte an der Unterseite der Oberkante lösen.

    • Ziehe die Glasscheibe weg von der unteren Kante des iMac und lege sie vorsichtig beiseite.

    • Trage die Glasscheibe nicht nur an den Saughebern, da sie dir sonst runterfällt, wenn ein Saugheber sich löst.

    • Löse die Saugheber, nachdem du die Glasscheibe sicher abgelegt hast, da der Unterdruck auf Dauer das Glas beschädigen kann.

    • Denk dran, den Bildschirm und die Innenseite der Glasscheibe vor dem Wiederzusammenbau sorgfältig zu putzen, da eingeschlossener Staub oder Fingerabdrücke deutlich sichtbar sind, sobald du das Display einschaltest.

    you should do this mac up, because, for me, one of the suction cup failed, and the glass fall into the lcd screen. Now there is a big hole in it...

    Lau -

    do you still have this panel?

    Alpha Dimension -

    Reassembly: After powering on and running for a few minutes, found a large whitish patch on the screen. Persists after powerdown.

    Turned out to be condensation, though it didn't look like it - more like fine white powder rubbed in. Humidity is very high this time of the year. Fix: start airconditioner in a room, leave it running a while, take iMac in, prise open the glass again. Condensation vanishes instantly. Keep it out for a ~15 minutes running infinite loops to get iMac nicely heated up and fans running. Snap glass back.

    I used a Swiffer dry cloth to get all the dust off the screen while just blowing with my mouth at a steep angle. I know I didn't get every speck, but the screen looks perfect once assembled and lit again. Removing the glass from the screen is pretty easy if you need to re-clean it.

    Jay Gillibrand -

    I used a microfiber cloth instead, which worked well. The same type as yo use to clean eye glasses, but in a larger form factor.

    Daniel -

    The Swiffer idea worked great! I just brush it over the LCD and glass panel lightly, and all dust particles are gone quickly. The screen after boot up looked beautiful. Thanks!

    I strongly recomment to detach the suction cups while working at the rest of the steps. In my case after half an our i heart a crack noise behind me on the table... The vacuum of one of the suction cups braked the glass! maybe there should be a warning in the Repair guide

    shippe -

    I didn't crack the screen, but it popped out of the shims and then popped back in, as if the glass edge is magnetic or has steel in it to connect to magnets. Be careful with this step — it is pretty nerve-wracking, but doable!

    Alex Reynolds -

    You need a big clean surface free, or at least 2 or more free surfaces because the iMac, the glass and the LCD display are quite bulky. You'll also probably need space for a tablet or a laptop to read this guide while you are working. And don't forget room to work on the optical unit and for the tools you are going to use. I covered a large table with a double layer of bubble wrap. In my opinion it's better to put the glass face down to limit powder sticking on the internal surface.

    Roberto Blandino -

    Thanks good advice! I was wondering exactly about the working space issue!

    matteoslataper -

    I am doing this repair now. After successfully lifting off the glass panel (yay!), dust blew out of the lower open edge. So I sprayed a can of air around edges. But a poof of the “air” condensated on the LCD. Does anyone know if I can clean the LCD same as how the glass is cleaned (damp cloth with equal parts white distilled vinegar/distilled water) and if not then how?

    Amy C -

    Hi Amy,

    To clean the LCD panel, I would suggest using a clean microfiber cloth and rubbing alcohol. Distilled water can be used, but avoid regular water, which contains minerals. Make sure the microfiber cloth is absolutely clean and has no hard particles sticking on the surface, which will scratch your LCD when you wipe it.

    Wet the surface with some alcohol and gently wipe with the microfiber cloth. Wipe in one direction.

    Arthur Shi -

    I find that the LCD is not as fragile as we all think. they are very much like any LCD on a tv or monitor. There is no extra glass on the front of a monitor. Not the 23 HP Pro Displays I have anyway. I know this because I punctured one moving my video wall. so I took it apart to know how its put together. I will say, there are several 'lens’ like sheets and a reflective (silver} sheets that are the same size as the panel. and a 1/8”piece of acrylic, all behind the LCD panel. Take care with them and clean as you would your monitor.

    My suggestion is to stand the iMac up after the panel is secured back into the body of the iMac and clean while its vertical. took me 3 attempts before I realized that while laying flat the surface is large and collects dust with mind blowing speed.

    Stu Blair -

    If the LCD glass is badly cracked and broken you need to be extra careful removing as the sharp shard of broken glass can scratch/harm the underlying screen as they may “fall in or onto” the screen below.

    I found that strategically putting sheets of 8x11 paper(s) under the sharpest, largest broken sections help protect the underlying screen. A vacuum was also helpful removing some of the small glass shards.

    Mark Hilliard -

    Be advised: I did a perfect replacement of the hard drive, temperature sensor to the SSD, LCD screwed in, glass cleaned. I went to put back the final glass, I set the bottom edge in place and as I slowly moved to have the magnets take hold, they pulled the screen out of my gingerly held fingers, and smacked into place……cracking the glass! Ugh! So, on this last step, hold tight as you put the glass back in slowly. It will cost you about 40-50 bucks for a new glass (mine is on it’s way).

    R R MOOS -

    Yikes... that sucks. thanks for sharing this information. I took everyone's advice and removed and placed this back very very carefully.

    iSeeU ChilinHomie -

    Don't trust the suction cups after you remove the screen cover. Used both hands to hold this piece carefully!

Your topic says "Replacement" not "Removal". There is nothing here about how to obtain a new glass panel and how to install it.
