Hello i have some issues with the set up for the gamecube! I connect the Yellow/white/red wire in the input device. My tv got only hdmi input so i used the hdmi output on the device. the sound works fine the the image is in black and white. I've try two diffirents Yellow/white/red wire so i don't think that the problem. is there anything i can do ? do i need to buy another wire?
Thanks, and sorry for my english it's not my first language
