Nvidia GF6600GT TV-out (s-video/composite)
I'm unable to get tv-out working on my 6600GT. Both with composite and S-video, I get diagonal colored scrolling lines all over the screen as if the signal is out of sync. It's like if you run your CRT with too high sync rates.
I only get this on a TV-card. When plugging into an ordinary tv, it doesn't even detect the signal (cause it's out of range I assume). I get the same behaviour in both Linux and Windows, and I have remembered to select the right standard (PAL-B). I've tried all kinds of resolutions and refresh rates / horisontal sync rates, they all yield that out-of-sync picture.
I haven't found anything similar on google, so does this mean my TV-out unit is fried or something? I'm suspecting this because I see sparks between the grounds of the male and female s-video connectors when connecting the tv to the card (possibly because of a ground loop), and this could have fried the output circuit on my 6600gt(?)
