Quick Answer / Summary: On a TV with a composite input, plug yellow into the video socket and white and red into the audio sockets of the AV IN bank, then select that input (AV, VIDEO, or Composite) in the TV’s input menu. The signal is 480i or 576i. If the TV has no composite socket, a passive cable will not help – use a composite-to-HDMI converter, which scales the 480i signal to a format the HDMI input accepts.
Connecting composite to a television is a two-part job: the physical socket bank, and the input selection in the TV menu. Older sets have the yellow-white-red bank on the front or side panel and accept composite natively; modern sets have largely dropped the socket, which changes the cable decision entirely. This guide covers finding the input, selecting the source, and the converter path when the TV has no composite socket at all.
Finding the Composite Input on a TV
The composite bank is three RCA sockets – yellow, white, red – usually labeled AV IN, VIDEO IN, or COMPOSITE, and often shared with a component bank on the same panel. Shared banks are a common source of confusion: on many sets, the yellow video socket sits inside the component bank because the panel reuses the same physical space, and the TV routes the signal based on the input selection rather than the socket alone. On CRT and early LCD sets, the bank is often on the front or side panel for camcorder access; on later LCD and plasma sets, it moved to the rear. Sockets are usually color-coded but the color is sometimes printed rather than molded, so read the label rather than relying on color alone.
Older Sets: CRT, Early LCD, Plasma
These sets accept composite natively and often have two or more AV banks. The signal is displayed at its native 480i or 576i, or scaled to the panel’s resolution by the TV’s internal scaler. No settings beyond input selection are required.
Modern Sets: Smart TVs and HDMI-Only Panels
Most current televisions have removed the composite socket entirely. A composite cable has nowhere to go, and the fix is not a different cable but a converter – composite to HDMI – that takes the 480i signal and presents it to the TV as a digital input.
Selecting the AV Input Source
The physical connection is half the job; the TV must be told to display that input. The input menu lists each bank as a separate source – AV1, AV2, VIDEO, COMPOSITE – and selecting the wrong one produces a no-signal screen even though the cable is correct. With shared banks, the TV may also require the input to be set to composite rather than component mode for the same physical sockets, because the panel is deciding how to interpret the signal. When a source is connected and the TV shows no signal on every input, re-check the source’s own output setting before assuming a cable fault.
When the TV Has No Composite Input
An HDMI-only television cannot accept a composite cable directly, and no passive adapter can convert the signal – composite is analog standard-definition and HDMI is digital. The solution is an active converter: a small box that accepts the three RCA plugs, digitizes and scales the 480i signal, and outputs HDMI. Expect the converter to add a small amount of processing delay and to output the picture scaled to 720p or 1080p without adding real detail – the source is still 480i. Match the converter’s output format to the TV’s preferred input resolution and the picture will be as good as the source allows.
TV Composite Input by Type
| TV Type | Composite Socket | Max Input | Note |
|---|---|---|---|
| CRT television | Yes, often front panel | 480i / 576i | Native format, no scaling |
| Early LCD / plasma | Yes, rear panel | 480i / 576i | TV scaler upscales internally |
| Modern smart TV | Rarely present | 480i if present | Check the rear panel carefully |
| HDMI-only panel | No | n/a | Requires composite-to-HDMI converter |
Real-World Application Scenarios
Reviving a retro console on a CRT or an older LCD television. Connecting a VCR or camcorder to a secondary TV for playback. Classroom and hotel AV carts where a standard-definition player feeds whatever display is installed. Households with a modern TV and a legacy media source, where the composite-to-HDMI converter path keeps the old device usable without replacing it.

Frequently Asked Questions (FAQ)
Q: How do I connect a composite cable to my TV?
A: Plug the yellow connector into the video socket and the white and red connectors into the audio sockets of the AV IN bank, then select that bank (AV, VIDEO, or COMPOSITE) in the TV’s input menu. On shared banks, confirm the input is set to composite rather than component for those sockets.
Q: My TV has no yellow composite socket – what now?
A: An HDMI-only television cannot accept composite directly, and no passive adapter can bridge analog standard-definition to digital HDMI. Use an active composite-to-HDMI converter: it accepts the three RCA plugs and outputs an HDMI signal the TV accepts, scaled to 720p or 1080p without adding detail.
Q: Why does the TV show no signal with the cable connected?
A: Two usual causes: the wrong input source is selected, or the source device is not set to output composite. Check the TV’s input menu first, then the source’s video output setting – most multi-format devices let you choose composite, S-Video, or component.
