The term "RCA" refers to composite video. These video cords typically have three plugs that are red, yellow and white. Composite video is commonly used on televisions and other electronics to carry low-definition audio and standard-definition video signals. RCA cables are popular pack-ins with modern DVD players and video game consoles. These cords are typically reliable--and do not break easily. However, if you're not sure that your RCA cables work, you can easily test them.
Instructions
1. Determine the type of RCA cables you are testing. The cord will have one end with red, white and yellow plugs. The other end may be the same style, or it may have a solid plug-in--depending upon the device.
2. Plug one end of the RCA cables into an electronic device. Use a DVD player, gaming console or VCR. If you have a solid plug, insert it into the "Video Out" port. If you have the color plugs, place them into the color-coded slots.
3. Hook the RCA cables into your television. The color connectors push into the respective ports. The "Input" port where you plug in the cable will be marked with a number.
4. Switch the television to the "Input" channel number from Step 3. Turn on the device on the other end of the RCA cable. Check for video clarity and sound quality. If you receive a clear picture and sound, the RCA cables are working.
