I have a 12" G4 867mhz. When I plug in the mini vga out, or the video out, the screen flickers, and the power flickers too. Also, when I plugged my PB into my parents emac via firewire to transfer files it flickers. I unplugged the power adapter, and I was able to transfer the files. as soon as I plugged it back in, it shut the powerbook, and the emac down.
any ideas what it might be? bad ground or something?
