iMac Intel 21.5" EMC 2544 Right Speaker Replacement

Remove the following five Phillips screws holding the lower support bracket in place:

• Four 3.2 mm screws
• One 1.7 mm screw
• On at least some EMC 2544 machines, all five screws are the same size.

Remove the lower support bracket from the iMac enclosure.

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.

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 running 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.

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.

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.

Starting from the top right corner of the iMac, wedge a plastic card between the display and frame.

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".

Slide the card toward the center of the display to cut any of the remaining adhesive along the top right corner of the iMac.

Wedge the plastic card into the top right corner once again and let it stay there to keep the adhesive from resettling.

Insert a second plastic card into the gap between the display and frame located at the top left corner of the iMac.

Gently twist the card upward, slightly increasing the space between the display and frame.

Slide the plastic card toward the center, again stopping just before the iSight camera.

Wedge the plastic card back into the top left corner.

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.

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.

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.

Lift the display up to a near-vertical position.

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

Use a spudger to loosen the right speaker cable's connector from its socket on the logic board.

Pull the connector downwards to remove it from its socket.

Remove the two 10.0 mm T10 screws securing the right speaker to the rear enclosure.

Pull the top of the right speaker away from the rear enclosure, about half an inch, to expose the antenna cable running down its right side.

Insert the tip of a spudger between the right speaker and the antenna cable that is routed into the speaker's right side.

Run the spudger down along the right side of the speaker to pry the antenna cable from its channel in the right speaker.

Pull the right speaker straight up about an inch, toward the top of the iMac.

Lift the right speaker straight up and remove it from the iMac. This may take some force, both hands and rocking the speaker right and left to get it out.
