I am trying to hook up a karaoke machine to a Samsung smart TV I cannot get that video to work without being fuzzy. I have yellow component plugged into the yellow and put on the TV but it is still coming up fuzzy, The same thing happens when I try to plug in my video camera and watch home videos. I currently have my cable hooked up with a green cord plugged into the yellow input and that works fine so what am I doing wrong?? Thanks
