How to fix Multi color Vertical Lines on a Vizio E470i-AO TV


Does the menu function display the same lines? What kind of cables are using ? (HDMI, Component vid, S-video, co-ax)
Were you as tenacious checking all cables/connections as you were the electronics? Lets rule out this all too often over-looked possibility.
Do you still get the lines with nothing connected to the TV? (no source connected)
