    How do you tell if a scart cable is RGB? :lease:
    The ones I own have 20 pins and look exactly the same as the scart on my Xbox advance scart pack (except they are not gold).

    i can't remember where I bought them from or how much i paid as i don't think my (Old) CRT is RGB Enabled.

    Have a Hitachi 32LD7200 on order though so I'll need to know!

    THanks,

    Matt

    To do the new screen justice it would probably be a good idea to buy a new scart lead to use with it anyway! LCD do seem to show up faults that you wouldn't see on a crt.

    I'd suggest at least a Thor cable or, if you can afford it, buy an Ixos or some other well known brand.

    This is yet another thing I cannot stand about SCART. There's no way of telling until you plug it in and see (unless you have the tech knowledge to open up the cable and tell from hte way it's wired).

    If the scart lead is fully wired, then it will support RGB. 20pins showing would indicate a fully wired lead.

    I beg to differ. The number of pins is meaningless.

    Check for connectivity between pins 7, 11 and 15 using a multimeter. ie, pin 7 to 7 at each end, and so on.

    I still think you should buy a new cable!

    Yeah, my Sega Dreamcast RGB SCART cable only had about 9 pins.

    Not totally. Most scart leads that simply have AV-OUT -> AV-IN on either end usually have the required number of pins for the job (5/6 pins either end). Of course the best way is to continuity/bell test as you suggest, but 21 pins in either end is a good indicator, but not a conclusion, of a fully wired lead

    But you should always open any SCART connector before using it!

    Open one of the caps (usually after unscrewing a cap around the cable), and see if you have a bundle of similar wires inside a single shield.
    If so, discard cable.

    Check if all pins are present and connected. If not, discard cable.

    Finally, check if there are some separate coaxial leads in the cable that are connected to the pins near the notch and to three sets of pins along one of the sides. And some possibly thinner shielded cables to pins near the square end of the plug. The remainder of the pins can be connected with unshielded wires.
    That is a good SCART-RGB cable.

    Really, what you should look for is a bundle of different sizes and shapes of wire in the cable, not 20 similar wires. Then it should be fine.

    There is a quick and dirty way to tell if a TV is displaying RGB. Very gently pull one end of the SCART plug from the socket. You need to pull it out very gently and at an angle so some pins disconnect before the others. If the signal is RGB, you should see a colour cast on the picture as one of the colours will be lost (depending which is on the pin that you have removed first). If difficult to describe but easy to do.

    Depends on the make and model of the set. Many don't give any indication.

    Hi
    when you select an av input on the hitachi it also displays the connection type on screen. eg. AV1 composite only!, AV2 & AV3 composite or RGB depending on the cable, AV4 component and so on. I still can't beleive how many inputs this thing has :D
    I use a QED rgb scart to connect my dvd player and IXOS component cables for my xbox which is chipped and switched to ntsc to support hd modes.

    Hope that helps!

    Cheers,
    H
