If your iMac has suffered extensive damage from a drop or a spill and your warranty will not cover the cost of replacing the monitor, you can save money on repairs by replacing the monitor yourself. An iMac uses specially moulded shells, so you must purchase the correct replacement screen to ensure a successful swap. According to the Apple website, opening your iMac will void the warranty, so only perform this task yourself when the warranty and AppleCare support have expired.

  1. 1

    Lay the antistatic mat on a table and place the iMac facedown on the mat. Slide the wristband on your arm and clip the cord to a corner of the mat. Touch a piece of metal to discharge any static electricity.

  2. 2

    Unscrew the Phillips screw in the middle of the long aluminium panel covering the RAM. Remove the panel and unclip the black plastic tabs holding the RAM cards in their slots. Pull the cards out with your fingers when they pop slightly out of their slots.

  3. 3

    Flip the iMac onto its other side and stick suction cups on the plastic screen covering. Grab the suction cups and lift them up to remove the covering and reveal the T8 Torx screws holding the aluminium case to the display.

  4. 4

    Unscrew all the T8 Torx screws from around the frame of the display, and lift the aluminium case up from the computer. Unplug the iSight camera from the top of the case before removing the case completely.

  5. 5

    Unscrew the rest of the T8 Torx screws from the rim of the display to loosen it from the logic board. Disconnect the black wire between the display and the board near the black cooling fan. Lift the display slightly to find the other two connections between the display and the logic board.

  6. 6

    Detach the blue card from the lower right side of the logic board, and unplug the last black wire from the upper left side of the board. Remove the old display entirely.

  7. 7

    Reattach the black wire from the upper left side of the logic board to the new display. Replace the blue card to its connection on the lower right side of the display. Align the display with its holes in the frame of the computer and connect the black wire, near the fan, to the display.

  8. 8

    Replace the T8 Torx screws in the display to hold it to the logic board. Reconnect the iSight camera to the aluminium case and slide it over the display. Screw the T8 Torx screws into the aluminium case, and then replace the plastic screen over the display.

  9. 9

    Flip the iMac over and insert the RAM cards in their slots, fastening them down with the black plastic tabs. Replace the long aluminium panel over the RAM cards and attach it to the case with a Phillips screw.
