Introduzione

Rimozione del display per la sostituzione o l'accesso ai componenti interni del computer.

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.

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...

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!

I followed the procedure in the Apple Technician Guide and it was a lot easier. Stand the iMac upright on the stand (as per normal operation) and then carefully tilt the top of the unit towards you while holding the top of the LCD. The LCD just falls forward into you hands. It is also then easier to disconnect the cables.

iandh - Replica

This procedure can be VERY dangerous. Why? Because there is the possibility of a gravity disaster if you lose control of the screen and it falls before you disconnect the interface cables. I know. It happened to me. After studying the Apple directions I came to the conclusion that I would need both hands on releasing a couple go the cables and decided to tape off the screen in the open position - which I did very carefully and securely. What I did not account for was the tape not adhering. Needless to say when it came loose the screen fell and ruined the connector sockets (and my computer). This could also happen just trying to hold the screen with one hand while spudging the connectors apart with the other as well. SO. LAY THE iMAC DOWN! DO **N O T** GIVE GRAVITY THE CHANCE TO RUIN YOUR DAY like it did mine!

After disconnecting the VSync cable, I was able to keep the screen wedged apart by 8" which gave me enough working room to extract and replaced the hard drive without having to remove Step 6 - 8. This resulted in a faster change out of the hard drive.

ITSupportGuy - Replica

Amen brother! These are great guides, but could be improved with tips to simplify some processes. I just did the same as you, and it was quick and easy, with less chance to damage cable connections.

Hobowan Kenobi -

thank you for the tip. faster swap-out and less risky. cheers

Eric -

Once I put the tip of a very small flat-head screwdriver on the other side of the spudger tip, the connector popped out.

Alex Reynolds - Replica

I've managed to break off the fitting in step 6 trying to remove the screen, would anyone know the part to buy or how to fix this?

jonostainsby - Replica

It is very hard to detach the connector with the spudger. I tried forcing the connector out with the spudger by pushing on one side and then the other repeatedly. After several times it finally came out. A tool would be useful for this; there must be special plyers for doing this. Fingernails on either side seems most obvious, but maybe there is a downside to this ?

Daniel - Replica

Rocking it back and forth with some “outward” pressure on both sides was the key. This was the only connector in this upgrade that gave me a problem.

Do step 7 first. The cable is much shorter and more fragile, you'll have more space to remove the other cables if that one is removed first. On my mac, the cable in step 7 was glued down and had to be freed up before I could pull the connecter out of its socket.

Hello Fabio, can you please re-up the picture? It doesnt seem to be online anymore :(

Thanx a bunch!

Esteban Garcia -

Good idea! I used two chopsticks as they are longer. Placed them near the corner and use one of the T10 screw's hole in the side of LCD panel to prop it up. Fit perfectly and very sturdy. This gave me plenty of space to work with the replacement.

I skipped step 6, 7 and 8 and were using some flip chart pens to put them between the frame and the display to make the work on the hard drive. Works great.

LUIS - Replica

me too. All went well expect replace this flat cable which is tricky almost when my view is low and I've got big finger. I broke the cable end connector to motherboard but I don't know if I damaged the connector on motherboard. I'm waiting from Apple service for diagnostic.

I would suggest on the guide to add a step to explain how sensitive is to replace this cable. iMac should lay on the back and it should have some stuff to maintain the motherboard elevated in order to insert the display port flat cable to the motherboard on a less stressful way.

This image is 100% inaccurate. My mac has a different style connector that needed to be pinched on each side to release the cable.

Alex Nelson - Replica

Its not 100% incorrect for him as this was his connector. It was only incorrect for you.

asthomas -

The ZIF display cable is tricky to get back in. I would suggest that this cable be the first one to be put back during reassembly. You need maximum wiggle room and visibility for this. Push in the display power cable *after* this one.

ganesh - Replica

How do you get the ZIF connector back in? Some screenshot or instruction would be very helpful. I cannot get mine back in.

Brian Bowlin - Replica

This is really difficult, but essentially it slides in - with no discernible click. A *slight* tug on the lever lets you know its connected. Horrible thing.

Use the ‘bic pen’ trick and you don’t have to remove this for most things but I had to go ‘back in’ to remove the super drive. I then used the tip next down and removed this connector at the screen also and put this end back in first with no screen in the way.

Jem Marsh -

I found the best way for me to reinstall the ZIF cable in was to lay LCD panel on its face and gently peel the black tape on upper part of lcd to expose and remove the connector there. At this point the ribbon cable is free and you can insert the hard to align connector to the board. Set LCD into imac and connect the small push connector next to the ribbon cable on board. It was easier to see and then reconnect the cable to the upper portion of LCD and tape it back over. Reinstall other connectors etc. This way worked best on my 27" iMac as it was much easier.

thewiseone71 - Replica

The is a great tip

Jem Marsh -

I had to replace the cable due to damage from trying to reinsert it at the logic board and I found it best to re-attach it exactly the way that thewiseone71 describes it above. If you disconnect the part at the top with the tape around it, this goes much easier and there is less of a chance of damaging the port on the logic board where it attaches at the other end. I think some photos of this port, and the way this cable goes back in would be a great addition to this tutorial. Replacing this cable would also make a great tutorial.

What would be really helpful to this guide, and this image is the closest I can find in the sequence, is a quick summary of exactly where the diagnostic LEDs are on this model (and what they mean, although the latter is easily googleable). I only mention this as I believe my PSU is goosed as no LEDs are illuminated anywhere, however I can only find references to 2009 and 2010 of the similar MYs which evidently have diagnostic LEDs in a different place, hidden under tape, and I suspect numbered differently. So I can't be 100% certain!

When I opened up my iMac, I was surprised at how dusty it was inside. You might want to have a vacuum cleaner handy to vacuum up the dust inside the case. Be careful not to vacuum up the screws, though!

FYI...I did this fix, upgraded my mid 2011 27" to a Samsung 850 EVO SSD Hard Drive. Everything went great except for two parts...

1. When I started up with my install media I got a three beep error and I could not install. I ended up using the CRTL-R at startup and did a network install that downloads an image of the original OS that comes with the system and allows you to install with the correct file.

2. Hard drive fan was spinning at full speed the whole time. This was annoying to say the least. Another person on this thread commented on this and said that you had to buy a $30 piece of software to fix it, I actually found another one that is free and works quite well (http://exirion.net/ssdfanctrl/).

There seems to be a missing step here. All the while one is removing the cables from their sockets it is supposed that the screen which is quite heavy is suspended in mid air… no, you are holding it up with one hand while doing everything single handed while in all honesty it would be nice to have both hands if for nothing else to steady your movements. So. Lets add a step. Lets figure out a solution and use some kind of prop until the screen is removable.

For starters, thanks for this great tutorial!

I have a small question though.

What is meant by "Carefully lay the iMac stand-side down on a flat surface."

If I lay the iMac on my desk, the mount is preventing it from going completely flat.

I find the 27" quite heavy to lift and was wondering if I was doing something wrong.

Anybody have any tricks to lift the LCD without too much lifting?

Thanks!
