    • Use your index fingers to pull the small bridge of material on the front bezel toward yourself.

    • Pull the Front bezel up with your index fingers.

    • Once the small bridge of material has cleared the RAM arms, lift the front bezel by its lower edge just enough to clear the bottom edge of the rear case.

  4. Re-orient your iMac so it sits upright on the stand. Insert a plastic card up into the corner of the air vent slot near the top of the rear case. Push the card toward the top of the iMac to release the front bezel latch.

    • Pull the front bezel away from the rear case.

    • Repeat this process for the other side of the front bezel.

    • It may be necessary to apply several layers of duct tape to the top of the access card to aid in releasing the latches.

    • If the bezel refuses to release, try pressing the lower edge back onto the rear case and repeat this opening process.

  5. Lay your iMac stand-side down on a table.

    • During reassembly, it is helpful to use several small strips of tape to hold the EMI shielding along the left and right edges of the display footprint out of the way before lowering the display into the rear case of your iMac.

    • Allow the EMI shield to hang down from the display.

    • Remove the four 8 mm with 2 mm thick head coarse-thread T10 Torx screws securing the display to the rear case.

    • These screws are recessed, so a thin screwdriver such as this is essential for removal. Bit drivers tend to be too short for this application.

    • It is strongly recommended to use a magnetized screwdriver so the screws won't fall into the iMac.

  13. Lift the display from its lower edge and pull it toward yourself to peel off the EMI shield attached to its top edge.
    • Lift the display from its lower edge and pull it toward yourself to peel off the EMI shield attached to its top edge.

    • Remove the LCD inverter from the metal bracket. It is held in with some light adhesive.

    • You can use a spudger to lift the inverter board slightly. Then it will come out easily.

  16. Attach the included plastic adapters to the replacement LCD screen. These must be used because the replacement screen is likely much thinner than the OEM panel.
    • Attach the included plastic adapters to the replacement LCD screen.

    • These must be used because the replacement screen is likely much thinner than the OEM panel.

    • The adapter with the larger leg space has to be mounted on the "right" side of the LCD. That's where the LVDS connector is located.

    • The brackets screw directly to the screen using the included phillips screws.

    • You should now have a fully assembled display ready for install.

    • Be very careful not to apply too much force when attaching the adhesive tape. The back of the LCD is very sensitive!

    • Vertical alignment:

    • Each bracket utilizes 2 screws mounted through 2 slots. This allows a few inches of movement up or down.

    • You will likely need to go back and make adjustments after the install.

    • Just loosen the 2 screws and slide the bracket up or down as needed and then tighten screws.

    • Mounting screen:

    • Mount the screen using the original torx screws used the mount the OEM panel.

    • Plug the LVDS cable into the logic board.

    • Reassembly and test:

    • Double check everything and once you are confident everything went well, install the front bezel.

    • Attach the power cable, and hit the power button.

    • You should now be greeted by a white screen and the Apple logo.

    • It should now be apparent if any alignment adjustments need to be made.
