    I just bought the Apple Video Adapter for my 17" iMac G5 and a cable to connect it to my TV, but the picture on the TV is black and white. I have tried different settings like changing from PAL to NTSC and vice versa, and changing the resolution and color settings, but without any success.

    I also tried the spanning hack.

    Does anyone know how to get color picture on the TV? :)

    Thanks in advance!

    Maybe you ended up with a PAL one when you needed NTSC? Or visa versa, call Apple and see what's going on, maybe you have a defective cable. :confused:

    Same thing here. Using the S-Video output, I get black & white only. Using RCA, I get color. This cord was from ebay. So I bought a new one, and same thing. B & W when using S-Video. I don't have an S-Video TV anyway, but I was at a friend's house.

    Well my brother has a 17-inch iMac G5 2.0 at home, I'll use my PowerBook video adapter and see if it works, the VGA adapter worked fine...hmmm I think there are some iMac G5 repair programs right? You guys should call up Apple and see what's going on.....this all seems very strange to me. :eek:

    I just replaced my iBook's 500mhz Logic board and tried to use my PowerBook G4's video cable with it and all I get is a black and white screen with the image duplicated horizontally but not scrolling. This is odd...maybe some adapters are for newer systems and some are for older systems?

    Hmm... :confused:

    Alot of TVs don't accept S-Video over scart, and only take the luminance half of the signal, with no colour information overlaid on top what you get is exactly as you describe - a black and white picture. It may work if you have the option to enable s-video in amongst your menu options.

    If you were feeding into a dedicated S-Video mini-din plug then it may be a fault on the TV.

    Well in my case I'm using a US Video Adapter with an iBook G3, when I use it with the PowerBook G4 it works fine, maybe the iBook G3 is from Europe or something? I used composite and the PowerBook shows up fine, the iBook doesn't. I do have a PAL to NTSC adapter, I'll give that a try later. :D
