    Default Color bleeding with RGB

    I have a model 1 Genesis that I am having some video issues with. When connected via RF, everything is fine. I also have a scart cable and scart-to-component transcoder that I got on eBay and when using that, the colors of the image seem to bleed horizontally. The image also appears slightly too bright which makes it look a little washed out. Both my Genesis and TV are NTSC if that matters. In my internet research on the issue I hear a lot of talk about adding resistors or capacitors across some of the lines in the scart cable, but as I am not very knowledgeable on the subject, I would really appreciate some expert guidance.

    [Edit]

    Disconnecting the Red and Blue plugs results in a vary sharp Black and White picture with no bleeding. I don't know if this is relevant.

    Maybe ask this seller if he ships to the US for you: http://cgi.ebay.de/Scartkabel-fuer-M...mZ200351960154 (otherwise I'd order the cable for you)

    Of all the TVs I had access to, most would not display a proper RGB picture with the regular SCART cables carrying composite + RGB. With the above cable I get 100% pure RGB on every TV I tried.

    The Mega Drive was far inferior to the NES in terms of diffusion rate and sales in the Japanese market, though there were ardent Sega users. But in the US and Europe, we knew Sega could challenge Nintendo. We aimed at dominating those markets, hiring experienced staff for our overseas department in Japan, and revitalising Sega of America and the ailing Virgin group in Europe.

    Then we set about developing killer games.

    Too many of the German SCART cables I've ran into have had one issue or another resulting in less than optimal image quality.... one type had wrong value resistor so you got mix of composhit and RGB, and no colors in 60Hz...
    And other was perfect all around EXCEPT it had too few ground signals connected so image was having major ghosting horizontally...

    This is the problem I'm experiencing with the UK SCART cables I got. It displays a perfect RGB picture on maybe two out of ten TVs, and a mixed composite + RGB signal on the others.

    How can that fix anything ? MD does not have SoG so best you get by removing composite pin is rolling scrolling image....

    Oh, okay. Thanks for pointing that out. I just repeated something I read somewhere else... and wrong at that.

    Edited my recommendation.
