hello-

I have a Ti G4 powerbook(dvi) that will not display to the screen. The machine boots up, but only shows to the external display. I got this computer like this....broken so you will understand this next comment. When the computer boots and as I am looking at the external monitor, I do not see any thing besides a white screen. After about 30 seconds, the login screen just appears. The question is....shouldn't there be some type of display activity between pushing the power button and seeing the login screen? I thought that this was out of the ordinary so I thought to mention it. If not, then I am hoping I can diagnose the screen issue.

I am trying to rule out the inverter, or the cable before I replace the LCD.

thanks,
Bob
