    • The glass panel is fixed onto the front bezel with fourteen magnets around its perimeter.

    • Stick two suction cups to opposing corners of the glass panel.

    • To attach the suction cups we sell, first position the suction cup with the movable handle parallel to the face of the glass panel. While lightly holding the suction cup against the glass, raise the movable handle until it is parallel with the other handle.

    • If your suction cups refuse to stick, try cleaning both the glass panel and the suction cup with a mild solvent such as Windex.

  3. iMac Intel 20" EMC 2133 and 2210 Logic Board Replacement: passo 3, imagem 1 %32
    • Gently pull the glass panel straight up off the iMac.

    • The glass panel has several positioning pins around its perimeter. To avoid shearing these pins off the glass panel, be sure to only pull straight up during removal.

    • Be meticulous about cleaning the LCD and the inside face of the glass panel before reinstallation, as any fingerprints or dust trapped inside will be annoyingly visible when the display is on. Placing the glass flat, inside face down, on a fresh aluminum-foil surface is a good way to keep it clean.

  4. iMac Intel 20" EMC 2133 and 2210 Logic Board Replacement, Front Bezel: passo 4, imagem 1 %32
    • Remove the following 12 screws securing the front bezel to the rear case:

    • Four 25 mm T8 Torx.

  5. iMac Intel 20" EMC 2133 and 2210 Logic Board Replacement: passo 5, imagem 1 %32
    • Place your hands at the top corners of the bezel (to the side) and lift the bezel 2-3cm from the body by working from the top. After this you can also disengage the bottom of the bezel (the memory modules will prevent the bottom of the bezel to detach first). When reassembling, start with the bottom of the bezel.

    • The top of the bezel hosts a microphone attached to the logic board. Gently lift the bezel to not damage the microphone wiring or connector by accidentally pulling the cable.

    • At this point, you can either detach the microphone cable and remove the bezel, or keep the microphone cable attached and rest the bezel on your work surface or the chassis of the Mac.

    • To fully detach the bezel: disconnect the microphone cable connector, removing tape as necessary.

    • To keep it attached, leave the microphone cable attached to the logic board, and place the bezel 'above' the chassis, with the microphone cable forming a hinge.

    • If you keep the microphone attached to the chassis, make sure you don't accidentally damage the microphone or logic board by bumping into the loose bezel.

Superb instructions. just replaced my iMac 2007 with another motherboard as I had a faulty ram slot and put in a new SSD hard drive. Would have struggled without this step by step guide.

Thanks. I was able to successfully replace the logic board following these instructions. I'm not sure I would have been able to do it on my own.

How is named the block right above the ram slots? This thing covered with the bright aluminium « mini-Manhattan » :)  (or « porcupine »)?

I thought it was the CPU itself but if I read correctly, CPU is under the 45° structure. Right? Thank you.

Peri Vanvuchelen - Responder

I’m sorry for the late answer, but I believe the chip under that heat sink is the North Bridge. It controls data transfer between the CPU, RAM, and graphics.

What is the thing above the ram slots? That thing with the bright aluminium « porcupine » on top of it ;) thank you
