To put it as simply as i can, I have a Radeon 4800 HD, with two dvi connectors and what i think is an s-video in the middle of them. I have an s-video to composite adapter which is plugged in as well as my lcd screen on the dvi next to it.

I am then running from the adapter the 3 normal composite cables, yellow for video and the other 2 (red,white) for sound. Now the pc detects there is a tv connected, via s-video. And i am getting the sound of my pc through the tv, but regardless of what i try the tv picture stays black.

I have tried pretty much all available options in ccc (catalyst control centre), including resoloution, refresh rate and forcing detection of a tv. Now i have had this working before with exactly the same setup including tv and graphics card. Also i have the most up to date version of drivers and ccc.

If anyone has any ideas or just anybody that has tried this before and had problems please post, ive been trying to fix this for nearly 2 days now and its driving me INSANE!!!!

Many thanks
Ben
