Trying to hook up a device like a DVD player with an AUX output that has the red, white and yellow phono plugs to a television that only has a coaxial connection cannot be done without the use of an RF modulator. The cable you use that goes into the phono plugs is called an AV cable. It is a connection designed to separate the right and left channels of the audio and gives the video it own path. A coax connection has all the information stuffed into one cable.

Skill level:
Moderately Easy

  1. 1

    Plug one end of the A/V cables into the AUX output by matching the colours on the plugs with the colour of the outputs.

  2. 2

    Plug the red and white plugs on the other end of the A/V cable into the red and white "Audio In" on the RF modulator. Plug the yellow plug on the A/V cable into the "Video In."

  3. 3

    Twist the end of the coax cable, which is called an F-connector, onto the connection marked "To TV" on the RF modulator.

  4. 4

    Twist the F-connector on the other end of the coax cable onto the cable connection on the back of your television.

  5. 5

    Plug the power cord on the modulator into your wall outlet.

  6. 6

    Turn your television to channel 3 and select channel 3 on the channel selector on the front of the modulator. If the picture doesn't come in clear, switch your television to channel 4 and flip the switch on the modulator to channel 4. Decide which channel will give you the best picture.
