I have a Toshiba SD 6000 DVD video player and my TV is not recognizing it. I am using the connections provided [red, white, yellow cables]. I have plugged them into the corresponding color coded links on the DVD and TV. The TV links indicate Component. When I go to Input on the TV, the selection for Component is grayed out and I only have highlighted selections options of TV and HDMI1-which is the cable connection. Do I need to purchase an HDM I cable? Why didn"t one come with the TV?
