Your DVD output may not going to component out (assuming your cables are ok-check the other DVD outputs on the TV). It may be going to s-video out or composite out (I gave a buddy a Toshiba DVD player and had the same problem). Check the manual or the menu. You'll be fine.
Why can't my 32" Sony LCD show component out?
I have a small home theater set-up in my basement. I use some of my older equipment. I hooked up my Zenith DVD player via component out to my Sony Bravia Component inputs and got no signal. I had the correct input selected on the Sony TV. Thanks for the help
