Introduzione

Un iMac da 27" è una grande cosa. Un iMac da 27" con il display rotto è una grande cosa rotta. Non permettere a un LCD guasto di bloccare le potenzialità del tuo iMac. Usa questa guida per sostituire il display nell'iMac da 27" versione 2010. display dell'iMac Intel EMC 2390 da 27".[/summary]

Far aderire una ventosa accanto a ciascuno dei due angoli superiori del pannello di vetro. Per far aderire le ventose, per prima cosa posizionarle con la maniglia semovente parallela alla superficie del pannello di vetro (come evidenziato nella prima e nella seconda immagine). Tenendo delicatamente la ventosa contro il vetro, sollevare la maniglia semovente finché non è parallela all'altra maniglia (come evidenziato nella terza immagine).

  • Do not use the suction cups to carry the display glass because if one of them fails to stick, you could drop the screen and break it.

  • The original iMac box makes a good place to store the glass panel. Otherwise, a padded horizontal surface, like a towel on a desk will do nicely.

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 - Replica

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.

jtowner - Replica

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 - Replica

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!

Frank303 - Replica

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 - Replica

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 - Replica

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.

Sollevare il pannello di vetro in perpendicolare rispetto alla superficie dello schermo LCD, affinché sia possibile sgombrare i piedini di montaggio in acciaio inseriti lungo il lato sottostante al bordo superiore del pannello di vetro. Estrarre il panello di vetro dal bordo inferiore dell'iMac e riporlo da parte con attenzione. Durante la reinstallazione, pulire con attenzione la parte interna del pannello di vetro e la superficie dello schermo LCD, poiché la polvere e le impronte digitali saranno sgradevolmente visibili durante l'utilizzo della macchina.

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...

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 - Replica

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!

dtsai2 -

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 - Replica

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 - Replica

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 - Replica

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 - Replica

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.

The replacement display I received did not have a bracket around the edges so I can reinstall it. On the old display, it seems the bracket is screwed in, but even with all screws removed, I cannot get it to budge. Is there a trick? Is this even possible?

wooten1138 - Replica

Reassembly: be careful with the screws! The magnets attract them and the screwdriver as well! Better to use a screwdriver without replaceable end insert. I had to use one of this second type and I struggled a lot!

Be careful with any tool while lifting the edge of the display. Under the top left edge of the display sits the bluetooth-antenna-connector. I pulled it out while lifting. It was not such a great problem, cause i could just plug it in again. But maybe you could cut the small cable depending on the tool you use to lift.

Gee - Replica

The display is quite heavy, an is fitted with a tight tolerance. I found it very difficult and dangerous, lifting it with any tool in one corner while the iMac was lying down. Instead, after removing the T10 screws, it was quite easy pulling the display out of the iMac with my fingers on both sides, while the iMac was in the upright position. By doing that, you can easily hold the display with one hand and reach for the connecting cables with the other

Georg P - Replica

I broke the short ribbon cable that attaches to the inner top of the display but all the pics show the display completely removed after all cables are disconnected without the short ribbon cable intact. Does this short ribbon cable have a purpose and does it need to be reconnected? If so, how? Or is it just some worthless control put in by Apple to show its been messed with when brought back for repair? Thanks

This cable is very small and fiddley to remove if you don't have much in the way of finger nails. The cables are very thin and fragile.

James York - Replica

It took me a bit of work to remove this cable, it was a hassle actually. What worked for me, without any tools, was to use your index and middle fingers' nails and pull it. That worked better than the index and thumb. Took me like 15 minutes, more than what it should take.

thefinalzeta - Replica

Yes, me too! It stuck terribly hard and I spent most of the time for the repair for this s**** little connector. I thought all the time, I'm gonna break it or tear off these tiny cables... All the other cables were *rather* easy-going. In the end I finally got a new SanDisk Ultra II 480 GB SSD working.

And thanks to the SDD Fan Control app it is sooo silent. Thanks to Exirion!

Nick van Hill -

When the cable comes out, make note of which side has the gold contacts visible. On my cable, you could only see them from the "top" side (aka, as you look down on it). From the "bottom" or back side of the cable, you could NOT see any gold contacts. This will help to orient the cable when reconnecting it.

markcerv - Replica

In my case, all the cable connectors were oriented having the golden contacts, as seen from the wide side of the connectors, oriented facing away from the board

Georg P - Replica

From this point onwards I found very useful a flashlight to illuminate inside the iMac.

Roberto Blandino - Replica

Take care not to pull off the socket off along with the connector as happened to me.

Fortunately there are used pull on eBay. Even saw one that had the same socket ripped off also.

Joel Yang - Replica

FYI; Cable in 27 EMC 2390 I just worked on looked different. Was simple flat connecter with nothing other than blue coloring on end. Just flat gold connectors on bottom side. These kinds are very tricky to extract and even trickier to reinsert as there is too much flex and not enough slack/room for finger/tool to get back in.

My solution is unconventional but works. I do not remove the cables (!). I work on the floor, lying on my belly. I open slowly and carefully only as far as the cables inside will allow. Use a flashlight so you can really see clearly. Then I prop up the both sides of the display using anything the right size (box, a pair of boots…) It is crucial of course that you have things propped up securely so screen can stay a few inches up without hands! I use a very short #10 Torx so I can remove the old HD. There is barely enough room to work but it is do-able with care (and light!). As I am usually putting in an SSD these days, I simply use electrical tape to secure it. Close slowly. Test

This connection is very fragile, and many people have broken the display connector on the logic board. You need to carefully pull the connector out, and when putting it back together, you need to carefully push the connector back in.

i did break mine. do you know where to buy that component?

Cris - Replica

In my iMac the cable was stuck to the structure of the computer with a piece of foam tape. Pulling it very gently, gradually it detached with no damages.

I pulled a bit too hard and metal cover over the module attached to the logic board came off from one side exposing metal teeth. To my surprise I managed to put it back. Even bigger surprise Mac works just fine!

I replaced hard drive and added a second SSD on a 2010 27" iMac. Everything seemed fine for about a year, and now the fans run continuously. I think it's this cable in Step 8; I'll get around to opening it up to check.

Hard to learn, easy to master. There are a lot of trap cables that are not very long. For best results, I like to use cardboard hard drive boxes to prop up my LCD display to a 30° angle so I can reconnect cables with both my hands.

Does anyone know if the display from a 2011 27" iMac is compatible with a 2010 27" iMac? The 2011 in my office died, but the 2010 still works fine, albeit with color trouble due to a malfunctioning display.
