You are flamed.

The two tests already tried, RGB SCART & Composite video should be good enough to prove that there is something wrong. There is no need to waste money on a S-Video amplifier board.

What is interesting is that there RGB screen does not look as it should if either G, B or both were not functioning. There is WHITE on the screen which is only possible if all three, RGB are working to some extent. Might be possible if you screwed up the cable and wired G & B together? Or perhaps it is just a side effect of having the contrast / brightness turned way up on your TV?

The composite screen looks more like you would imagine if some of the other colour components were low but not missing.

I made a few quick examples where I killed one or more of the colour component channels.

RED ONLY

RED + GREEN

RED + BLUE
