Sony DAV-DZ260 bad picture on projector through s-video?

[jackrmee]

Hi, I am trying to connect mt Sony DZ260 Home cinema to an Infocus Litepro 580.

I bought a phono to s-video cable but the picture is black and white and fuzzy.
I can't understand why because my Sky box works fine in the s-video mode.

I tried connecting to the RCA (yellow port) but it doesn't seem to work. I think it may be faulty, so I need to use the s-video port.

Any idea what could be wrong?

Thanks
