24LF454B no signal - do I need an HDMI cable?

I've attached a picture showing how it's connected to cable TV. The previous TV worked with this configuration (and no HDMI cable), though with this setup I'm getting a "no signal" message on the screen. The owners manual says "For the best picture and audio quality, connect the external device and the TV with the HDMI cable", though it does not say its a requirement. Thank you for any suggestions.
