iMac Intel 27" EMC 2309 und 2374 AirPort Karte Austausch

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

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.

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.

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

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 :)

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

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…).

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 …

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.

Duct tape works too!

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

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!

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.

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.

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

I noticed that the vertical sync cable seems to have been updated since the guide was produced. It now has a more normal plug and socket and 'regular' wires instead of the flat ribbon cable shown here. I used narrow nosed pliers instead of tweezers to unclip it as I was afraid that just pulling on the wires could have broken them.

be sure to keep this cable, because it does not come with a new display!

I changed the HD yesterday and when I reinstalled the Display I had the same problem then Peter Sinclair. I started to panic first. But then I reinstalled the Pannel without re-insterting the cable at all and nevertheless my iMac works perfectly since 14 hours now. I'm really confused!

My vertical sync ribbon cable had two of the four contacts bent back, it may even have been like this originally. I straightened them out as best I could under a magnifying glass, and after reinserting, everything is working OK. Seems this cable is not particularly critical. Also, I used needle nose pliers for this and the other connectors, I can't get enough grip with tweezers.

Tweezers didn't work for me due to the angle and lack of grip (they kept slipping and I was concerned about squeezing any harder). I just used my fingers to grab the connector as close to the connection as possible for both removal and insertion and it worked just fine. I have big hands and meaty fingers, so this method should work fine for anyone.

I also did this step and then went straight to step 10. I installed a SSD so I didn't do step 15 either. You can use this to control the fans: http://exirion.net/ssdfanctrl/

Overall, great guide! Thank you.

Adam's technique with the chopsticks works great. I didn't even have to disconnect the V-sync cable. Mine wasn't plugged in for some reason. I guess the LCD works without it.

This was for me the hardest step when reassembling the iMac.

I had to open and close the iMac several times as each time some of the cables was not properly connected: The vertical sync, the display data cable connector, even the Bluetooth antenna was off at some point and I had to re-open every time! Finally I left the vertical sync cable disconnected as with each operation it was in very bad condition and impossible to plug in. I'm amazed at how bad designed is this cable and how easy is to break it! It's nice to know that they improved it, poor technicians.

I'd like to replace it in the future but I really don't know how or if it is available in its more up-to-date version… I didn't feel like dissasembling everything again to see how is it connected.

The portion of this little cable that plugs into the receptor is stiffer than the rest of the cable, but it is very slippery. For me, it was also very tight. Tweezers and fingers just slipped right off of it. Fortunately, I didn't tear the cable. I ended up using needle-nose pliers wrapped with cellophane to get traction. It was also very difficult to reinsert. By raising the display to the maximum level with all the other cables connected, I was able to push it in with my fingers.

Also: if you get any smudges on the display, a lens pen works great to remove them. I used a swiffer to pick up dust.

Pull the cable AWAY from the connector. Some cables have a plastic connector cap attached to the end. This one does not. The cable just slips out as if pulling a stick of gum out of a package. I used my index finger and thumb, no tweezers needed.

I also plugged it out with my fingers, got more feeling in them. Put it in the same way. There is no barb or something on the cable, so this should be quite safe when not using too much force. And I also used chopsticks to keep the display up, just like an engine hood.

This ribbon had me flumoxed for a while. I had expected to have to remove the terminal from the circuit board. All you need to do it gently pull on the ribbon directly and it will come out of the terminal.

I followed the above tips and used chop sticks as struts to support the internal screen at an angle, whilst I worked on the hard drive. Allowed me to skip the remaining cable removal steps and go straight to step 10. And I didn’t need an extra set of hands to hold the screen whilst I worked.

So far so good. Had trouble with this first ribbon wire and not even sure I got it back in all the way. Computer is working just fine right now with Windows 10. The chopstick idea was absolute genius and saved me so much time!

I found step 6 the most difficult of the whole procedure. The way I unclipped the connector was from the front, with my thumbnail. There's a little ridge over which the cable clicks tight. If you use your thumbnail to lift the connector over that ridge, you can then easily remove the cable. (Maybe iFixit should that advise to the guide, since especially step 6 is a bit too concise imho.)

Agreed with previous comment :You should be very careful after step 5 - it may be necessary to do the step 7 before the step 6 because the connector on the motherboard for the LCD data is very very fragile. I broke it and found that a lot of people broke it as well .

I ran into a big problem with step 7: my display data cable did not have any sort of plug to connect to the logic board. Instead, the cable seemed to be soldered onto the board or simply run under this small copper-colored band. There was no plastic plug to detach/attach.

I was afraid to pull on the cable and break something, so I simply had a friend hold up the LCD and I replaced the logic board without removing the display. I'm not sure what I would have done if I needed to replace the drive.

Has anyone else run into this issue where the display data cable doesn't have a plug? And are there alternative ways to detach it safely?

@fronesis - on my iMac it wasn't possible to pull out the connector at first. There was a small rectangular metal clip which locked the connector in place - this had to be pulled up first, and then the connector came out extremely easily.

I'm having blackscreen issue and this cable is my main suspect. Here is my post regarding this issue.

Black screen after SSD install (suspect is monitor cables)

you will break your computer if you follow this step during the reassemble!

it’s not possible to reconnect the display with the board because the cable is way to short to maneuver the connector in place and you have almost no sight - you’ll not see what you’re doing! the better approach is disconnect the cable on the display as well (since the connector here is more robust) and insert the connector on the board as a first step without having the display in front of your face..

This plug pulls out straight up towards the top of the screen. That is, standing above the top edge of the screen, straight towards yourself. DO NOT pull it ‘up’ 90 degrees from the board it is mounted on! You will deflect it away from the board—like I did, after reading this vaguely written instruction for this part of the procedure….

You can easily remove it by using two fingernails on either side of the plug to gently and slowly lever it out of the socket. BEFORE YOU DO, paint one side of it white or yellow, so you can re-install it properly….
