Turn off the PlayStation 2 and carefully unplug it from the power source. Also, it is important to eject the CD from the console before flipping the it upside down.
Once all of the screws have been removed, pry apart the plastic covers. Start by lifting the side containing the power cable and Ethernet port. Then, lift the opposite side to fully separate the two sides.
You may need to apply some gentle force to detach the covers. Be careful not to break the plastic screw pins.
Using tweezers, gently detach all three ribbons from the motherboard terminal. Unlock the middle orange ribbon to lift the black tab up on either side.
IMPORTANT: The orange ribbon is glued to the metal chassis. Gently pull the ribbon upward to make sure that you don't rip it.
What you see in this picture is the electronic components found in the PS2. We are now going to remove the top metal casing found on top of the motherboard.
