Try holding down Command-V while the system boots to boot it into verbose mode -- you should see some debugging output (white text on black background). You might also try "safe mode" to see if it helps -- see Apple's Mac OS X keyboard shortcuts for more info. Did it work before you changed the LCD? (Why did you change it?)

What should he do after entering verbose mode?
EFI (which displays the Picker) can talk to his display; XNU apparently can't. If it is able to display the debug spew in verbose mode, then that means the basic console driver works and somehow the normal CoreGraphics library doesn't like his screen; booting from a restore disk might work, or booting from a working Mac drive with the latest patches installed might work. We also might get some useful error messages.
Of course, if it stays black ... then, beats me. :)
+ OK, since it shuts down during the boot process I would guess when it goes to check the screen it finds the wrong one and ends the boot.
