OK, so I gather that you made the RGB cable (the one on the bottom) and not the VGA. As far as I can tell the only difference is that the RGB cable has a combined sync.

Problems could be:

Your TV has a YUV input and for some reason you thought it was RGB. In that case though there would be no picture at all.

It could be that your TV uses Sync on Green, but then it wouldn't be getting any sync information so again no picture at all.

My best guess is that you mixed the RGB channels up and probably mixed red with green or something.

Could you tell us a little more about the cable you made and the TV you're using?

The set is definitely RGB and it seems to only like using composite for the sync signals.

The cable is... Well, it's just Xbox 360 connector one end, SCART the other. It's just your average CRT set.

One thing I should add is that I can get luminance and chroma out of the lead, so the Xbox 360 unit is most certainly outputting component.

Oh, that's right. Your TV uses a SCART connector. I've never owned a television that had RGB input.

Did you make sure to link the proper pins together to make sure the xbox knows to output video in RGB+CSync and not Component/Composite mode?

I would go back and double check.

Then again you said you got a picture but with a green tint so again I'm inclined to think you mixed the color channels up. Double check to see if the color channels are in the right order.

I've definitely got the correct pins linked together, I've gone over that one so many times. This is why I'm baffled. I've tried mixing up the colour channels but all I get from every possible combination is weird colours, often with a dominant tint of R G or B (although FIFA 2006 looks pretty cool with a purple pitch).

make sure you removed the switch too.

I knew that.

Thanks Jim. Have a nice laugh-oh kitty picture for your trouble.

I guess it could maybe be the quality of the wires

If one of them was bad it could be causing resistance, causing the picture to shift towards another color.

Well, even with the switch in place the correct pins are shorted, so unless the switch isn't as simple as it looks (I was slightly "festive" at the time of making it all) then err... Yeah. I want a VGA cable now, but I'm not going to make one because it'll end up transporting me back in time or something.
