43pp925 video-inputs-dead

[mahal]

I have a philips rear projection tv model no. 43pp925. All my video inputs are not working in the main screen but you can see it in picture n picture.
Component input works but theres to much red color on it. I tried to use the video output from my DVD(yellow) and connect it to the "green" input of the component video, it work but thers not much color on it. Can anyone tell me what's the problem. Thanks in advance
