Remove the display to access most of your iMac's internals.

Schritt 1 Display  ¶ 

Remove the eight T10 Torx screws securing the LCD to the outer case.

  • Remove the eight T10 Torx screws securing the LCD to the outer case.

Schritt 2  ¶ 

Carefully lay the iMac stand-side down on a flat surface. Due to tight tolerances, you will have to use a thin hooked tool to lift the display out of the outer case. As seen in the third picture, we made one out of a bent paperclip. Use a thin hooked tool to lift one side of the top edge of the display by its steel outer frame.

  • Use a thin hooked tool to lift one side of the top edge of the display by its steel outer frame.

  • After lifting the top edge of the display on one side, hold it out of the outer case while you use a hooked tool to lift the other side. A pencil or pen can be placed under the top edge of the display, parallel to the top edge and extending past the edge of the computer, to keep the first side propped up while lifting the second.

  • Do not lift the top edge of the display out of the outer case too far, as several short ribbon cables still connect the two components.

Schritt 3  ¶ 

Use a pair of tweezers to pull the vertical sync ribbon cable out of its socket on the LED driver board near the top left corner of your iMac. On some iMacs this may not be a ribbon cable but four separate, very fine and very fragile wires. Be very careful, if the tweezers slip off the plug, you will very likely pull a wire out of the assembly.

Squeeze the two display data cable connector arms together to unlock it from its socket on the logic board.

Schritt 5  ¶ 

  • Squeeze the two display data cable connector arms together to unlock it from its socket on the logic board.

  • Pull the display data cable connector away from its socket on the logic board.

  • Be very careful when disconnecting this cable as both the cable connector and logic board socket are extremely fragile. When reconnecting the cable later, use as little force as possible.

Schritt 6  ¶ 

Lift the display for enough clearance to disconnect the LCD thermal sensor cable connector from its socket on the logic board.

Schritt 6  ¶ 

  • Lift the display for enough clearance to disconnect the LCD thermal sensor cable connector from its socket on the logic board.

  • If your fan is spinning full speed after completion, check this connection or the hard drive's thermal sensor cable. The thermal sensor connector socket is very fragile, so be very careful when you connect back the sensor cable.

Schritt 7  ¶ 

Carefully pull the display toward the top edge of your iMac and lift it out of the outer case.
