Hi I have a 17" powerbook G4 which I want to connect to the TV. I have the s video cable which fits and shows the same on the screen as is being displayed on the TV, apart from the fact that it is in Black and white on the laptop (black and white as in old movies not black and white as in pure black and pure white). Any ideas on how I can sort this out.

Cheers Alison.

Lovely Powerbook G4, Mac OS X (10.4.7)

    let me get this straight. the image on your TV is fine, but your PowerBook desktop is black and white? When you unplug the cable, does your desktop go back to color? while the cable is plugged in, can you still control your desktop like normal (aside from the lack of color)?

    Yes the image on the TV is fine but powerbook is black and white. When I unplug the cable it goes back to colour. When the cable is plugged in I can still control the desktop like normal.

    Thanks for your time.

    Ensure that the colour profile is set to 'Color LCD' for the Powerbook display under the 'Color' tab, in the Display preferences when the television is connected.

    Although, what you're describing sounds much like a hardware issue, and odd that the symptoms aren't the other way 'round (i.e. your Powerbook screen fine, and your television B&W/Grayscale).

    It sounds to me like a hardware problem with your PowerBook. have you tried this with a different s-video display?

    Duh!!! What a fool I am, it is the other way around. The laptop is colour, and the TV screen Black and White. So problem still happening, just other way around.

    What was I thinking, sorry.

    Are you using an S-Video to SCART adapter in order to connect your Powerbook to your television? If so, then it may be the case that your television doesn't support the colour sent via S-Video, since it has no true S-Video connection.

    However, if your television has a true native S-Video connection, and you're not using an adapter, you should look through the menus on your television, and make sure that the S-Video input is set to your Powerbook's format (i.e. either PAL or NTSC). You should try this, even if you are using an adapter. It may work.

    If you're still having problems, then I would suggest that you should contact Apple, and/or the manufacturer of your television.

    That could be it, my TV is an old Sony, around 12 years old. And I am using the svideo to scart cable.

    Cheers so far, will have another fiddle with it.

    In all honesty, it doesn't sound like it's an issue with the Powerbook at all. It sounds like it's an issue with the television, whether it be a simple menu thing, or whether it be due to its age (i.e. its lack of a native S-Video connection).

    I use an S-Video to SCART adpater with my television (which is about five years old), and if I have the S-Video set to NTSC, is displays in back and white (or greyscale). If I change it to PAL (which is what it should be set to), it displays in mighty-fine colour!

    Have a flick through your television's menus.
