Reclaim your chat capabilities, use this guide to replace your combination iSight camera and microphone cable.

  • With the hinge free to move, the iMac will be unbalanced and hard to work on. Repairs are fast and easy with an iMac service wedge, but can be completed without one.

  • Before beginning any work on your iMac: Unplug the computer and press and hold the power button for ten seconds to discharge the power supply's capacitors.

  • Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply. Only handle the board by the edges.

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.

Starting on the left of the display, near the power button, insert the iMac Opening Tool into the gap between the glass panel and the rear enclosure. The hub on the iMac Opening Tool will keep you from pushing the wheel in too far. If using a different tool, insert no more than 3/8" into the display. Otherwise, you risk severing antenna cables and causing serious damage.

Use the tool like a pizza cutter—roll it along through the gap, and it will cut the foam adhesive through the center. Be sure to always push with the handle behind the cutting wheel. If you pull, the wheel might get pulled out of the handle. Run the tool up along the left side of the display.

Continue along the top of the display. You may want to run the tool back and forth through what you've already cut a few times, to ensure you get as much of the adhesive separated as possible.

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

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.

After doing the replacement the adhesive still sticks quite good enough to hold the screen in place. Maybe this isn't rock-solid, but enough for me.

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.

While the opening tool cut most of the adhesive, the display will still be slightly adhered to the case. A plastic card will be necessary to free up the last of this adhesive. Set the iMac face-up on a table. Starting from the top right corner of the iMac, wedge a plastic card between the display and frame.

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

Gently twist the plastic card sideways to create a gap between the display and frame. Move slowly and be careful not to stress the display glass too much—you only need to make a gap of about 1/4".

With both plastic cards inserted as shown near the corners, gently twist the cards sideways to increase the gap between display and case. If there are any sections that seem to stick and won't separate, stop twisting and use one of the cards to cut the remaining adhesive. Begin to lift the top of the display up from the frame.

While holding the display up with one hand, use the other hand to unplug the display power cable. Lift the display up enough to have easy access to the connector, but not so much that you stretch the cables and stress their connections (about 8").

Sure could use a magnified picture of this connector and socket, especially the first time you go in. And it is the most critical step of the whole operation — bung it up and we’re toast.

Hi bstaud! If you hover over the image you can click on the magnifying glass and get a large image of any guide photo. Hope that helps!

Lift the display up to a near-vertical position. At this point there is still a strip of adhesive along the bottom of the display, that will hold the display to the frame like a hinge. You can loosen this adhesive by working the display up and down a few times.

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 - Antwort

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.

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.

Lift the display up from the frame and remove it from the iMac. It may be necessary to slowly lift from one side, to peel against the remaining adhesive. Be very careful handling the display—it's big, heavy, and made of glass.
