first powerbook g4 and s-video out help please
sorry you're having trouble. i've got a 800 mhz tibook and connect it to my tv via s-video to rca fairly often without any trouble. i use the s-video to rca plug that came with it and then any old rca cable sitting around.
once it's plugged in and the tv is set to video in, i just hit "detect displays" and the computer recognizes that it's plugged into the tv. i can then mirror the display or use extended desktop.
it sounds like your s-video to rca cable is probably messed up, and i'd just try a new one, though it could be the s-video card as well i suppose, but i'd try to the cable first. i would imagine that adapter should be cheaper than a dvi to analog cable, though i could be wrong.
