I don't have any component cables, but will try and get some and give it a go.
It's just really strange, on the old CRT TV the picture is great via SCART. On the new Flat screen I get nothing with HDMI and via SCART I get a picture but with a green colour. I have tried different cables, I think the only other test I can do is try a different TV, but I know my *** box and PS3 work fine on that TV.
When it boots on the new TV via SCART I get the proper loading screen from VIX in full colour, then as it loads, It flicks to the green picture and then finishes loading. It's like it loads something that affects the image, but again absolutley nothing via HDMI.
