if its a close pair of scrolling horizontal bars , it "could" be due to a ground loop issue.what is the make/model of tv ?
Is the line blurry and grayish/black or is it just a discontinuity in the image?The former is possibly a ground issue. The latter means you need to enable wait for vsync in your video drivers or emulator as you are getting "tearing".
