Use this guide to save money by replacing only the LCD, not the entire display.

  1. Remove the two 6.3 mm Phillips screws near the lower left and right corners of the display.
    • Remove the two 6.3 mm Phillips screws near the lower left and right corners of the display.

    • Removing these two screws may be difficult. It is helpful to open the display as much as possible for clearance to use a screwdriver. Also, a combination of #00 Phillips and small flathead screwdrivers along with a pair of tweezers may aid in removal.

    It is much safer to follow the instructions for removing the entire display (PowerBook G4 Aluminum 17" 1-1.67 GHz Display Replacement) before removing these screws by bending the display beyond its tolerances.

    I've already spent 30 mins trying to remove these screws. DO NOT attempt this unless you have plenty of time to waste. Just take the top case/keyboard off and remove the screen assembly to save yourself a big headache. Thanks for the great site.

This is not for the faint of heart I would not recommend doing this. Over 2 hours taking it apart another 2 putting it back. No real directions as to putting it back togeather. The Basel needs to be put on the top first for it has the most clips. Take a picture of it when you get it apart so you can see how to put everything back as in the cables and wires. This has got to be the worst design ever. Also for $20 replace the inverter board at the same time, so you don't have to take it apart again.
