Introduction
Use this guide to remove or replace the AirPort/Bluetooth card in your iMac Intel 27" Retina 5K Display.
-
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 case.
-
Use the tool like a pizza cutter—roll it along through the gap, and it will cut the foam adhesive through the center.
-
Run the tool up along the left side of the display.
-
Continue wheeling the tool up around the top left corner.
-
Cut the adhesive along the top left of the display.
-
Continue along the top of the display.
-
Push the tool around the top right corner of the display.
-
Wheel the tool down along the right side of the display.
-
Finish pushing the opening tool to the bottom of the right side of the display.
-
Set the iMac face-up on a table.
-
Starting from the top right corner of the iMac, insert a plastic card between the display and frame.
-
Gently twist the plastic card to open the space 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".
-
Slide the card toward the center of the display, to cut any remaining adhesive.
-
Put the card into the corner again and let it stay there to keep the adhesive from resettling.
-
Insert a second card into the gap between the display and frame in the top left corner.
-
Gently twist the card, slightly increasing the space between the display and frame.
-
Slide the plastic card toward the center, again stopping just before the iSight camera.
-
Insert the card back into the top left corner.
-
With the cards inserted as shown near the corners, gently twist the cards 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 adhesive in the problem area.
-
Begin to lift the top of the display up from the frame.
-
While holding the display up with one hand, use the other to unplug the display power cable.
-
Flip up the metal retaining bracket on the display data cable.
-
Disconnect the display data cable.
I replaced HDD to SSD and assembled parts again. When I boot up the iMac, I found black lines on display (looks partly not broken).
I searched Internet, and some says graphic card problem, but I didn't touch anything but cable to lift up.
Could the damaged display data cable cause this situation? I hope I could fix this by just replacing the cables..
-
Lift the display up to a near-vertical position.
-
If necessary, a plastic card can be used to cut any remaining sections of the bottom adhesive strip.
Would have been helpful to box the same red area when using the plastic card to separate the glue. Since the red blocked picture is inverted, if someone doesn't pay close attention it may not be obvious that the area of concern is at the right top of the graphic pictures in which the plastic card use is being demonstrated..
-
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.
-
With the hinge free to move, the iMac will be unbalanced and hard to work on. Repairs can be completed with the iMac laying down, but are faster and easier with an iMac service wedge.
-
Remove two 10.0 mm T10 screws.
-
Gently rock the right speaker slightly to the right, to allow access to its cable's connection on the logic board.
-
Use a spudger to loosen the right speaker cable's connector from its socket on the logic board.
-
Pull the connector to the right to remove it from its socket.
-
Lift the speaker straight up and remove it from the iMac.
-
Use the flat end of a spudger to disconnect each of the four antenna connectors from the AirPort/Bluetooth card.
-
Remove two 3.7 mm T5 screws securing the AirPort/Bluetooth card to the logic board.
-
Push the end of the AirPort/Bluetooth Card slightly toward the rear case and pull it straight out of its socket on the logic board.
