How to Plug Composite Into Component

How to Plug Composite Into Component

Traditionally, almost everyone is used to the red, yellow, and white cable you connect to your device for video and audio output. This 3-head cable is known as a composite cable, RCA cable, or AV cord and is available on old devices. However, newer TVs don’t have an AV input. They feature a component input with two reds, white, green, and blue ports. This connection type is designed for enhanced video output.

To connect your RCA cables to your component input, simply plug the red and white composite cables into the corresponding component input (this transmits audio signal) and plug the yellow RCA cable into the green component input. The green component on your TV or device is often labeled as “Y “or “video” for video signal transmission. Set your device to AV input with a remote and you are good to go.

You want to set it up like this:

Composite  🠢   Component
Yellow          🠢   Green (Y Video)
None           🠢   Blue (Pb Video)
None           🠢   Red (Pr Video)
White          🠢   White (L Audio)
Red             🠢   Red (R Audio)

We will break down the complexities of connecting an RCA/Composite input to a component port in this post.

What You Need To Connect Component into Composite

  • 3 RCA cables (Red, Blue, and Green) and two stereo RCA connectors.
  • TV with component video-in or an adapter or receiver if the TV does not have a component video in. the adapter function is to convert the component video cable 3 ports into an S-video output.
  • Screwdriver
  • Wire strippers

Other alternatives you might need for the connection are:

  • HDMI to a monitor’s DVI connection.
  • Receiver With Components Video-In
  • Relevant hookup cables
  • An F-type Coaxial cable connector.

How to Plug Composite Cable Into Components Video Inputs Directly 

Step 1: Turn Off All Power Source

Following the first rule of all electrical works, you need to turn off all power sources. Ensure that all power sources are turned off and remove all electrical attachments like extensions, electrical cables, and other electrical connections from the socket. This is to prevent short circuit or electrical accidents.

Step 2: Identify the Different Colors on Your Composite Video Cable

These colors are Red, White, and Yellow. An easy way to go about the connection is to ensure the colors are the same on the composite video cable and the device you want to connect to. You will find a red and white audio input on your component supporting device. You will also find a green, blue, and red video input. In most devices, the input ports will be labeled as Y, Pb, and PR. Even if this is not the same on your devices, it will be something similar.

Step 3: Connect The Component Cables

Look for the part labeled “Components” behind or by the side of the device and plug your compost audio cables into the red and white port of the component input. After this, look for the video input of your component with the color code green. While there are three video inputs, we will only make use of the green input. Alternatively, if you can’t find a green input, look for ports marked with Y, Pb, and Pr and plug your yellow cable into the port marked “Y.”

Step 4: Change your Device Or Tv Input to “AV Input”

Once your composite or RCA cables are plugged in successfully, pick up your remote and change the input mode of your device to “AV input”. Your video should pop up instantly.

Other Ways to Connect Component to Composite

Composite Connection With Coaxial Wire

This will be almost similar to the initial step too. Coaxial wires are also known to have the following wires, namely shield wires, Y-wires, and a red or white wire.

The first step will be to connect the component video cable to the red, green, and blue ports of your TV. These ports will most likely be labeled as Y, Pb, and Pr on your TV and on the other end into the antenna decoder. If you use an over-the-air antenna signal, then plug one end of the coaxial cable into the port labeled “RF in” or “antenna in”.

Connecting Component Cable to AV Receiver

To make the video component connection, ensure to plug in one to one of the available component video input ports. Once this connection is established on the receiver, plug in the other end of the cable to the connected device, e.g. a VCR player.

Turn on your Devices

Note that all your devices were turned off before you made any connection. Now that all connections have been made, turn the devices on with the TV first and the receiver as the last to be turned on.

Technical Steps To Plugging Composite into Components

What you need:

  • RCA cable (composite video cable)
  • RGB cable (Component Video cable)
  • Male to female RCA adapter (3:2)
  • Soldering iron
  • Solder

How to go about it

  1. Get 3 male RCA adapters and 2 female RCA adapters.
  2. Strip one end of the 3 RCA cables
  3. Strip and unscrew one end of the RCA cable at the point they connect to the red, green, and blue wires.
  4. Connect the black component video cable wire to the red one on the 3 RCA cables. This should be done with a soldering iron and a solder and finished up with a tape covering.
  5. The white wire of the component video cable should also be soldered to the green wire of the 3 RCA cables and completed as step 4 above.
  6. If there is a ground wire in the component video cable, then twist it up with the others i.e. the black and white wire. And finish it up with electrical tape for holding them together.
  7. Connect the 3 RCA cables into the 2 female RCA adapters. Make sure these are properly connected with no exposed wire.
  8. Screw the blue end of the adapter (male) to the red/green end of the female adapter.
  9. Connect the red, green, and blue component video cable to its corresponding color on the TV. Now, you should have a crystal clear signal on your TV. If for any reason the signal is not clear enough, check through the steps to see where you made the mistake to correct the error.


You can now plug your component to composite or vice versa like a professional. If you follow these steps to the letter, then you should have an error-free connection.
