    • Remove the two 0.7 mm Phillips #0 screws on the sides of the centerpiece motherboard cover.

    • Remove by hand the two hexagonal screws securing the digital visual interface (DVI) input.

    • The DVI is typically a blue/black connector with two built-in screw connections on either side. It is secured by hand tightening the two side screws.

    • Push the centerpiece motherboard cover toward the body to remove.

    • Caution: The circuit board contains capacitors (they look like cylinders) that can shock you if they discharge. Be careful not to touch them as you work. If possible, use a capacitor discharge probe to safely rid the capacitors of dangerous charges.

    • Remove the three 0.7 mm Phillips #0 screws connecting the motherboard to the monitor.

    • Remove the four 0.7 mm Phillips #0 screws.

    • Use a spudger or plastic opening tool to disconnect the two red and two blue connectors by placing the tool into the crevice and lifting up the connector.

    • Ensure that your pry tool is ESD-safe.

    • Examine the top of each capacitor to check capacitor life.

    • A domed top surface indicates a blown capacitor that needs to be replaced.

    • Replace necessary capacitors via soldering the old capacitor out and soldering a new capacitor in.

    • Refer to this soldering guide for How To Solder and Desolder Connections.


To reassemble your device, follow these instructions in reverse order.
