Hello. I have a Sony AVD-C70ES connected via component video to a Vizio TV. The picture won't display on the TV when a DVD is playing ... the sound is good. All of the color plugs on the Sony's component outputs are aligned correctly as are the component inputs on the TV. The TV input is set to the component source. Any ideas? I have tried 2 other sets of component plugs & a different TV with the same results. Thanks.
