Rotate the LCD away from the PSP to reveal the LCD and home bar ribbon cables.

Use your fingernail or the edge of a plastic opening tool to flip up the retaining flap on the following four ZIF connectors:

Home bar cable

Microphone cable

LCD display data cable

Touchscreen cable

Be sure you are prying up on the retaining flap, not the socket itself

After flipping up the locking tabs on all four connectors, use your fingers or a spudger to gently pull the cables straight out of the connectors.
