I am experiencing the same problem on my iBook G4 14" (1.42 GHz).
 
I tried accessing Open Firmware but got a white screen. I powered down, rebooted, let it power up and waited for a few minutes. I was able to hear the beeps that result from adjusting the volume with a corresponding level of loudness. I then pressed the power button and the enter key, and the iBook shut down.
 
I rebooted with external video ready to go.
 
External video works!
 
The primary image went directly to the external video monitor. I was not able to set up an extension to the desktop. Any changes I made to either video failed to get an image on the LCD.
 
I'm thinking the video cable's gone bad (or perhaps needs reseating) because a good cable would at least signal the iBook to setup extending the desktop to the external monitor. I will confirm once I get a replacement video cable and/or LCD.
 
Thanks for reading!
 
== Update ==
 
I just replaced the LCD with another one. I didn't test whether the replacement was working.
 
I was able to replicate the same white screen.
 
I'm going to test/replace the video cable.
