I have an Aluminum PowerBook G4 1.67Ghz since 2006.

3/4 (from bottom to top) of the LCD becomes either black or is jumbled each time I turn on the MAC or move the screen. I need to press the LCD at several locations in order for this problem to go.... any advice ?

re: Polanskiman; this is usually caused by a loose ribbon connector on the rear of the LCD. Open up the display, remove the LCD, lay flat and re-connect the ribbon plug.

First of all, awesome guide. I am using it in July 2015, and there is no way I could have successfully navigate the typical Apple laptop Rubik's cube of Powerbook maintenance.

Second, there is a REAL trick to removing the upper case here, and it involves knowing what those stupid internal metal catches look like so you can free them without folding your aluminum case into a pretzel.

re: ykuwabara; this is due to the differences between the Model A1095 (yours) and the newer A1138 (illustrated here). The A1138 combines the keyboard and trackpad signals into one cable.
