Stap 1 — Display ¶
Stap 2 ¶
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.
Stap 3 ¶
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.
Stap 4 ¶
Continue running the tool up around the top left corner.
Stap 5 ¶
Cut the adhesive along the top left of the display.
Stap 6 ¶
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.
Stap 7 ¶
Push the tool around the top right corner of the display.
Stap 8 ¶
Wheel the tool down along the right side of the display.
Stap 9 ¶
Finish pushing the opening tool to the bottom of the right side of the display.
Stap 10 ¶
Starting from the top right corner of the iMac, wedge a plastic card between the display and frame.
Stap 11 ¶
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".
Stap 12 ¶
Slide the card toward the center of the display to cut any of the remaining adhesive along the top right corner of the iMac.
Stap 13 ¶
Wedge the plastic card into the top right corner once again and let it stay there to keep the adhesive from resettling.
Stap 14 ¶
Insert a second plastic card into the gap between the display and frame located at the top left corner of the iMac.
Stap 15 ¶
Gently twist the card upward, slightly increasing the space between the display and frame.
Stap 16 ¶
Slide the plastic card toward the center, again stopping just before the iSight camera.
Stap 17 ¶
Wedge the plastic card back into the top left corner.
Stap 18 ¶
With both plastic cards inserted as shown near the corners, gently twist the cards sideways to increase the gap between display and case.
Begin to lift the top of the display up from the frame.
Stap 19 ¶
While holding the display up with one hand, use the other hand to unplug the display power cable. Make sure that you pull the cable out from the plastic tab, and not by pulling on the color wires.
Stap 20 ¶
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 logic board.
Stap 21 ¶
Lift the display up to a near-vertical position.
Stap 22 ¶
Stap 23 ¶
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.
Upon reassembly, now is the time to go to the Adhesive Strips Guide after cleaning off all the old adhesive. iMac Intel 21.5" EMC 2544 Adhesive Strips Replacement
