Hiya... I just received a powerbook 3400c/240 which boots up fine and will display video on an external monitor just fine. It doesn't have any video output showing on the internal LCD, even when the settings are at 800x600 @ 60Hz. I've been searching the web for days to find out what is necessary to fix this or what the problem is. I've seen a few instances at other sites where another person asked for help on the same topic, but never found any answers. I would appreciate any help I could get with this. Thank you for reading this far.
