iMac Intel 21.5" EMC 2544 Adhesive Strips Replacement

Replace the Adhesive Strips in your iMac Intel 21.5" EMC 2544.

Removing the display requires cutting through the adhesive around the perimeter of the screen. After the adhesive is cut, it cannot be used to re-seal the display in place, so you'll need to apply a new set of adhesive strips.

Edit Step 1 Adhesive Strips  ¶ 

  • Before you start placing strips, it is recommended to remove all of the old adhesive around the perimeter of the rear enclosure.

  • Use a spudger to scrape up an edge of the rear enclosure's perimeter, then peel with your fingers.

  • Repeat this process as necessary to remove all of the old adhesive adhered to the perimeter of the rear enclosure.

Edit Step 2  ¶ 

  • Start with the strip labeled 03, which goes on the right vertical side of the rear enclosure.

  • Before peeling off any backing, line it up against the frame of the iMac to get an idea of where it goes.

  • Peel the short piece of backing off the back of the strip.

Edit Step 3  ¶ 

  • Insert the tip of a spudger into the hole at the top of the strip from the side that still has a backing on it.

Edit Step 4  ¶ 

  • With the spudger still poking through the hole in the adhesive strip, push the spudger tip into the corresponding hole in the frame of the iMac.

  • Using the hole and spudger to anchor the position of the adhesive strip, line the strip up against the right edge, gently pulling up against the spudger to ensure the strip is taut, and stick it onto the frame.

Edit Step 5  ¶ 

  • Once you've aligned the bottom half of the adhesive strip, peel the longer piece of backing out from behind the strip.

  • If the bottom half isn't aligned properly, you can carefully peel it up and re-stick it before peeling off the lower backing strip. Be sure to use the spudger tip to anchor the top.

Edit Step 6  ¶ 

  • Align the upper half of the strip with the right edge of the rear enclosure, and stick it down.

Edit Step 7  ¶ 

  • Use your finger to smooth the strip labeled 03 along the right edge. Make sure it is neatly aligned with the right side of the frame and that it sits flat.

  • Do not peel off the front adhesive backing yet.

Edit Step 8  ¶ 

  • Work your way around the perimeter of the iMac, adding three more adhesive strips in the same manner.

  • Working counter-clockwise from strip 03, place:

    • Strip 02 on the top right

    • Strip 01 on the top left

    • Strip 05 on the left vertical

Edit Step 9  ¶ 

  • In some kits, the 04 strip may be split into a 4R, to be placed on the right half of the display, and a 4L to be placed on the left half.

  • Remove the leftmost backing of the strip labeled 04 and align it with the bottom left edge of the rear enclosure, about a 1/4 inch away from the edge of the display glass.

  • Repeat the process for the longer, rightmost backing.

  • Smooth out the strip from the center to ensure a good seal with no bubbles or wrinkles.

Edit Step 10  ¶ 

  • Peel up and remove the remaining backings from all of the strips around the frame.

Edit Step 11  ¶ 

  • Lay the bottom edge of the display glass against the top of the lower bezel. Be sure to align the edges of the display with the edges of the rear case.

  • Do not fully lower the display; there are still two cables that must be attached. Once you've set the display down, you won't be able to lift it again without damaging the adhesive.

Edit Step 12  ¶ 

  • While holding the display up with one hand, use the other hand to gently insert the display data cable connector into its socket on the logic board.

  • Be sure to press it straight into the socket, and insert it completely.

  • Secure the metal retaining bracket on the display data cable downwards towards the logic board.

Edit Step 14  ¶

Good Lord, why does Apple have to make it so difficult to upgrade or repair? There comes a point where design aesthetic just isn't worth it. Magnets, like I believe older iMacs use to attach the front glass, would have made it much easier. I'll take the extra bulk any day.
