First and foremost it is important to remove the battery and any slot in memory cards that are present.  Remove also any Game in the drive.

The Guarantee seal will need to be remove since two screws are beneath it so start with these four screws which are present in the battery compartment.  Two other screws are present on the other side of the PSP.

The next screw that needs to be removed is the external screw just next to the side bar code between the speakers.

Once these are removed the rear panel can be unclipped.

Now the screen can easily be seen but to remove the LCD screen you must first un clip the button bar which resides just below the screen.  Use a screw driver to un-clip . There is no need to remove the cable from the main board.

Once done unclip the screen with the same screw driver and slowly remove the two cables.  Before you do this you need to first lift the connectors slowly because they can be snapped very eaily.  Once this is done the screen is released and can be changed.

The same procedure can be repeated reversly to close the PSP back.
