Start by removing the two small screws on the top of the psp.
Take out your battery and remove the four screws accessible from the back.
Remove the last screw on the bottom and carefully take the faceplate off.
The blue strip under the screen is the home bar. Circled in red are the clips that hold the bar in place. Use your flathead screwdriver to pry the bar off the clips.
The lcd screen is also held in place by similar clips. Again, use your flathead screwdriver to pry between the screen and the black plastic part that it clips on to.
Do the same on the other side.
You should now be able to lift the screen up to get access to the cables. The backlight cable is circled in green and the lcd cable is circled in red.
The connectors have clasps that you have to lift up to release the cables. The picture shows what the clasps look like when open. They break easily so be careful and take your time!
