Sony PlayStation 2 Repair Manual page 6

Before flipping the console over you will need to remove the screws holding the controller ports assembly in
place. Once the screws are removed place your hand over the controller port assembly and flip the console
upside down. – CAUTION- There is a ribbon cable connected to the controller port assembly. If you do
not support it when flipping the console over it could cause the controller port to fall and cause damage
to the cable or connector- Please be careful.
Once the console is flipped upside down just pull up on the case from the back. Be careful when removing the
case so that it clears the USB connectors in the front. Once they are clear set aside the cover.
When the cover is off you will see something similar to what is pictured here.
