RCA cannot connect directly to HDMI — you need an active AV-to-HDMI converter box to bridge the analog-to-digital gap.
- You use an active AV-to-HDMI converter with RCA inputs and HDMI output
- You match cable colors: yellow (video), red and white (audio)
- The converter is powered via USB and your TV is set to the correct HDMI input
- You try to connect RCA directly to HDMI with a passive adapter or spliced cable
- The converter has no power or is unpowered
- You select the wrong HDMI input on your TV
Why RCA and HDMI Are Incompatible by Default
RCA carries an analog composite signal — one wire for video, two for audio. HDMI carries a fully digital signal that includes video, audio, and handshake data on a single cable. These are fundamentally different signal types. No passive adapter can convert between them because there is no electronics doing the conversion — just metal pins.
You specifically need an active converter with its own processing chip to translate the analog signal into a digital one your TV can accept.
What You Actually Need: An AV-to-HDMI Converter
An AV-to-HDMI converter is a small box — usually powered by USB — that takes your RCA inputs and outputs a digital HDMI signal. These are widely available online for under $20.
- Plug yellow RCA into the video (yellow) input on the converter
- Plug red and white RCA into the audio inputs on the converter
- Connect an HDMI cable from the converter’s output to your TV
- Power the converter via USB (use a wall adapter or TV USB port)
- Switch your TV to the correct HDMI input using the source/input button
Common Setups at a Glance
| Setup | Works? | Need | Note |
|---|---|---|---|
| RCA → AV-to-HDMI converter → TV | Yes | Active converter + USB power | Most reliable method |
| RCA → passive HDMI adapter → TV | No | Nothing will fix this | No signal conversion |
| RCA direct into HDMI port | No | N/A | Physically incompatible |
What If You Still Get No Picture or Sound?
If you’ve connected everything and still see a blank screen, check these first:
- Confirm the converter is receiving USB power — most have a small LED indicator
- Double-check your TV is on the exact HDMI input the converter is plugged into
- Try a different HDMI cable to rule out a faulty cable
- Verify the source device (DVD player, console, camera) is powered on and outputting a signal
If you’re dealing with other digital connection issues, see our guide on why USB-C to HDMI is not working for related troubleshooting steps that apply broadly to HDMI setups.

Bottom line: RCA can connect to HDMI, but only through an active AV-to-HDMI converter box — never with a passive adapter or direct cable. Buy a powered converter, match your cable colors, and select the right HDMI input on your TV and you’ll have a working picture every time.
