Help using av jack on pi 2

Question

Help please I have a portable DVD player with an audio/video input and it works with all devices except my raspberry pi 2. I also need it to fit in the DVD player case so I soldered the video cable to pp24 video and pp6 ground on the pi but I get no signal. All help is appreciated
