no idea about what support you can get from Samsung. For that you would have to try to contact them directly. As for the lines, we would have to see what they look like etc. Post some images of what your display shows with your question. Use this guide [guide|21499] for that. Could be a bad panel, bad t-con board or bad main board etc.
