What inputs do you have on your TV? What inputs were you using when you had the vertical lines? Quite often, if you have component (yellow RCA plug for video, white/red for audio) and S-Video they are really two alternatives for the same input, so if you use both S-Video and component (and something connected to each) you'll get a bad picture.
It all depends on what inputs you have on your set and which outputs you have on your components (set-top box, DVD player, VCR).
