There are different connection options depending.
If your have HDMI on both then use an HDMI cable.
Next best connection requires 3 RCA cables for video and 2 RCA cables for audio.
Third option is 1 RCA for video and 2 RCA for audio.
On some TVs if you want to use the last option this connection is shared with the second option so you have to go into the TV menu and set the input for composite video instead of component video.
