Yes, I did try booting with only the TV attached...nothing. I went ahead and tried the same TV with a GeForce4 video card with S-video with only the TV attached and it worked just fine. So it looks like a Savage video card issue of not auto-detecting the output.
Unfortunately they don't make drivers for this card anymore, and I haven't been able to find a user forum yet.
I guess the good news is that the card was only a couple bucks, so at least I'm not out too much. The bad news is that I now have to find a decent replacement from ATI or nVidia.
Do you guys know if ALL ATI and nVidia TV-out cards auto-detect the display?
Thanks.
