Hi,
Not sure if this is similar to your situation so apologies if its not.
I got a philips 21" tv and bought a sapphire radeon 9250.
I got a vga to scart cable (as suggested by sailorsat, I think the website was german, wolfsat or something, thanks again) and used soft 15khz.
Works a treat, have been having a few resolution issues lately but I think thats my own fault.
I tried the cables from ebay and none of them worked.
Hope this helps.
Sham.
