When you say you have no GPU does that mean no video card or onboard video at all?
If so, do you have any type of video-out port?
I have a P5Q and my Video Card has HDMI out, but has no S-Video. It
does not work with my older TV either, but is all ready for a new flat hi-def TV.
I have not found any type of converter to allow use of HDMI-out or VGA-out into S-Video.
In the meantime I am using my older Video Card which has S-Video for TV-out until I get a newer TV.
