    Chaps,

    Aquired an old Geforce 2 MX card with a TV out. Hooked it up to my TV, downloaded the latest XP drivers and was disappointed to see a black and white image ....

    I've checked the monitor is set as a Generic TV, Resolution is 800x600, refresh rate is 60Mhz (my TV is 100)

    I even had a play with Powerstrip... All to no avail...

    Can anyone help get a NICE colour image.....

    (The TV is the only monitor on this PC)

    ????????

    Sounds like you're using S-video out fed into a composite input?

    <how to suck eggs>
    S-video over SCART sends Luma (i.e. a black-and-white image) over the composite line and sends chroma (the colour information) over a second line. Hence, if you feed S-video into something expecting composite, you get a black-and-white image.

    Alternatively, you could have the graphics card outputtnig NTSC to a TV unable to handle it.

    HTH,

    Set the TV to receive an S-Video signal (if it can).
    Set the card to output in PAL (if it can).

    If the TV does not have an S-Video input then you will never get colour from the S-Video output on the card. Does the card have a yellow phono socket? That would be a composite output. S-Video or composite can be sent to TV via a scart socket.
    If the card can not output a PAL signal then your TV must be able to display NTSC. NTSC is the American video standard, UK uses PAL.

    It's usually possible to convert a graphics card to output to PAL from NTSC, however, it often involves flashing the bios of teh card. A process which CAN lead to failure of teh card. I flashed my Radeon 64 DDR VIVO to ouptut NTSC, as for my circumstances, it made life easier.
