Anyway, the first impression was quite disappointing with my PS2. Muddy CVBS, more I could not elicit the cable. But since I could not quite believe it, that would like to try bigben such a rough customer deception, I have the Scart connector opened just once and as expected, were (almost) all the necessary pins actually soldered.
The question remained, why I got to see no RGB image: it was the TV, which did not want to switch the signal input to RGB. So short-read and checked in Scart connector.
The pin carrying the corresponding switching voltage is not soldered.
Then I have the pins assigned to 5V, which provides the PS2 for these purposes. Was only a small cable bridge from pin 8 to 16 (see Wikipedia - SCART). In the same breath also equal to some sloppy running soldering improves (among others, are the masses of video and audio swapped) and reassembled.
Connected and finest RGB image to get face; So it is but with this cable :)
Who wants to test whether the connected cable is really RGB, can easily do with the PS2:
in the system configuration you navigate to the point "component video output". This is normally set to "RGB" and if you are now connected an RGB cable, the image after switching is green. Is it surrendered only composite remains colored in two settings, provided that the TV supports RGB.
With a little work pliers, the cable was connected also to a PS1. The modifications I had to perform in both the ordered cables and both now work as they should. Therefore, there still quite scarce, the 3 stars.
