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:

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.
