Horizontal lines and color problems?


this could be a format issue. When you change the channel do the lines go away ? If so try to go into the cable box (assuming you have a cable box) and reset your formats and exclude the format causing the lines.Make sure if your using component cables all colors match up.If this does not fix it replace your component cables/hdmi.All else fails unplug your TV wait 5 min. and plug it back in. Hope this works for you.
