    Hi everyone

    Basically im finally upgrading my antique sony 21inch tv with a sony fx68 which has two rgb scarts and i have a few questions about it:

    1)Can rgb scart cables be used for non rgb scart devices?
    2)I've read that some rgb scarts do not carry sound, so how do you get sound to the tv?
    3)As long as I stick to Ixos, Thor, or QED does it really matter which scart i choose as they are all around the same price range?

    Thanks for any help in advance

    Frankie

    1) There's nothing special about an RGB SCART cable. Only that all 21 pins are connected at both ends. Some cheaper cables only have selected pins connected, and these are not suitable for one purpose or another - eg may not carry sound, or may not carry RGB. Beyond that, it's down to how the sockets on the equipment are wired up. For example, a SCART socket on a TV that isn't wired for RGB won't work with RGB regardless of the cable. Ditto if the source device (eg DVD) isn't supplying RGB to the socket.

    2: What you say is true only if you have one with selected PINs connected. This would be a specialist cable; quite hard to find I suspect. If all 21 are connected (as most are), it will carry sound.

    3: Whatever you get, try to make sure that all the cables inside the bundle are separately screened. That, to my mind, is the most/only important factor.

    There is really no recognized standard for an RGB scart but it basically means that it will carry RGB signals but not other types of video signal or any audio signals at all. It is for those that want the best possible picture but aren't worried about sound as that will be handled by another cable directly from the DVD player or Sky box to the AV amplifier.

    If you are using the TV's amp and speakers for sound reproduction, make sure that you are buying a fully wired scart and any of the makes that you mentioned make decent scart cables.

    RGB uses six out of the 21 pins
    Red input, green input, blue input, red return, green return, blue return.
    a 21 pin wired scart (as already said) has always had these connections made.
    If the DVD/freeview/sky sends info down these and the TV knows to read them you get RGB.
