iMac Intel 27" Retina 5K Display 2020 Left Speaker Replacement

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.

If you are using the iFixit cardboard service wedge, follow these assembly directions to put it together.

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, and cut any remaining adhesive near the corner.

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.

Lift the display up to a near-vertical position.

Grasp the small tab at the end of one of the bottom edge display adhesive strips and pull the adhesive toward the top of the iMac to remove it.

Repeat this step with the other adhesive strip and remove it.

Lift the display up from the frame and remove it from the iMac. Lay the display face down on a flat, soft surface.

It may be necessary to slowly lift from one side, to peel against the remaining adhesive.

Use a Phillips screwdriver to remove the nine 3.2 mm screws securing the support bracket.

You may need to peel up the display adhesive lining the bottom edge of the iMac enclosure to access the screws.

Remove the lower support bracket (a.k.a. "chin strap") from the iMac enclosure.

Position the bracket diagonally.

Secure the rightmost screw enough to hold the bracket in place; keep it loose for now so the bracket can pivot.

Swing the left side of the bracket down until it sits horizontally in its original position.

Starting with the leftmost screw, install and tighten the remaining screws.

Remove two 10 mm T10 screws.

Unplug the left speaker cable by pulling it straight up out of its socket on the logic board.

De-route the cable from the gap between the hard drive and logic board.

Use a spudger to disconnect the power button connector from its socket on the logic board.

Lift the left speaker straight up, until the power button cable is exposed (about 0.5 inches).

Gently de-route the power button cable from its groove in the left speaker.

Lift the left speaker straight up and remove it from the iMac.

Push from the connector end as you pull from the speaker end to thread the cable under the hard drive's right bracket.
