If your machine works as it should on an external monitor then the video problem on the internal monitor should be related to the LCD panel or the LVDS cable.

Here's a link with great pictures of someone who had the same broken screen problem you have. http://www.david-reitter.com/software/Po...

The first thing to do would be to reseat your cables and review carefully the installation instructions you can find here: PowerBook G4 Aluminum 15" 1.5-1.67 GHz Display Replacement

Are you sure thenew display was good? Where did it come from?

Looks like a LVDS (video) cable issue. Double check the connections to the main board and to the LCD panel.
