You’ve got a stack of old discs gathering dust. Maybe it’s a rare Criterion Collection print or just a home movie from 2004 that isn't on any streaming service. You want to watch it. But you look at the back of your brand-new, paper-thin OLED and there’s nowhere to plug in those yellow, white, and red cables. It's frustrating. Honestly, it feels like tech companies decided physical media didn't exist anymore the second Netflix went mainstream.
Learning how to hook up dvd to smart tv units shouldn't feel like a high-level engineering project. Most people think they need a degree in electronics or a whole new player. You don’t. You just need to understand how the "handshake" between old-school analog signals and modern digital screens works. Modern TVs expect a high-definition digital signal via HDMI, while your trusty Sony or Magnavox DVD player is likely screaming in analog.
Why Your New TV Is Missing Those Colorful Ports
Samsung, LG, and Sony basically stopped putting RCA ports on the back of their TVs around 2019 or 2020. They’re trying to save space. They’re also betting that you’ll just pay $5.99 to rent the movie on Amazon instead of digging through your closet. But if you have the disc, why pay twice?
The problem is the digital-to-analog gap. Your DVD player outputs a signal that fluctuates in voltage—that’s what those RCA cables do. Your Smart TV is essentially a giant computer monitor that thinks in ones and zeros. If you try to just shove a cable in there, they won't talk to each other. Even if your TV has a "Component" or "Composite" input, it’s often hidden behind a single 3.5mm jack that requires a specific proprietary adapter you probably threw away with the box.
The HDMI Solution (The Easiest Path)
Check the back of your DVD player first. Seriously. You might be surprised. If you bought your player anytime after 2008, there is a very high chance it actually has an HDMI port on the back.
If it does, your job is easy. Buy a standard HDMI cable for five bucks. Plug one end into the player and the other into "HDMI 1" or "HDMI 2" on your TV. Switch the TV input using your remote. Boom. You’re watching The Matrix. This is the best way to hook up dvd to smart tv setups because HDMI carries both the video and the audio in a single cord. It also "upscales" the image slightly so it doesn't look like a blurry mess on a 65-inch 4K screen.

Dealing With the "Yellow-White-Red" Problem
So, you looked at the back of the player and it’s strictly old-school. No HDMI. Just the "trio" of RCA jacks. This is where most people give up. Don't.
You need an RCA to HDMI Converter. This is a little box—roughly the size of a deck of cards—that takes the analog signal and converts it into a digital signal your TV can understand. Brands like GANA or Portta sell these for under $20 on sites like Amazon or at Best Buy.
Be careful here. There is a massive difference between an "RCA to HDMI" converter and an "HDMI to RCA" converter. They look identical. If you buy the wrong one, it won’t work. You need the one where the RCA cables go in and the HDMI goes out to the TV.
- Plug your RCA cables into the DVD player.
- Plug the other ends into the "Input" side of the converter box.
- Run an HDMI cable from the "Output" side of the box to your TV.
- Important: These boxes usually need power. They come with a USB cable. You can usually plug that USB cable directly into the USB port on the back of your TV to power the converter.
The Component Video Alternative
If your DVD player is "fancy" for its era, it might have five ports: Green, Blue, Red (for video) and another Red and White (for audio). This is called Component Video. It’s actually better than the single yellow plug because it splits the signal for better color accuracy.
If your Smart TV has these matching five ports, use them. If it doesn't, you can get a Component to HDMI converter. It works exactly like the RCA one but gives you a slightly sharper image. Is it worth the extra five bucks? If you’re watching an epic like Lord of the Rings, yeah, probably. For a workout DVD? Don't bother.

The Secret "Adapter" Cable Method
Some modern TVs, particularly from Samsung or LG, come with a "Breakout Cable." It looks like a headphone jack on one end and has three female RCA plugs on the other.
Check your TV's manual or look at the back for a port labeled AV IN or COMPOSITE. If you see a tiny round hole that looks like a headphone jack, that’s your ticket. You plug the adapter into the TV, and then plug your DVD player's cables into that adapter. It’s a bit of a "dongle-heavy" life, but it keeps the signal clean without needing an external power source.
If you lost that cable, you can find them online, but you have to search for your specific TV model. Not all of these cables are wired the same way internally. Using a Sony adapter on a Samsung TV might result in a loud buzzing sound or a black-and-white picture. It's annoying, I know.
Troubleshooting: Why is the Picture Black and White?
You hooked everything up and the movie is playing, but it looks like a 1940s noir film. This is a classic "handshake" error.
Usually, this happens when you plug a yellow RCA cable into a "Component" green port on a TV. Some TVs use the Green port as a dual-purpose jack. You have to go into your TV’s System Settings or Picture Settings and manually tell the TV to look for an "AV" or "Composite" signal instead of "Component."

Another culprit? The PAL/NTSC switch. Many of those cheap converter boxes have a tiny physical switch on the side. If it's set to PAL (the European standard) and you're in the US (NTSC), the picture will flicker or lose color. Flip that switch and it should snap into place.
Smart TV Software Hurdles
Sometimes the hardware is fine, but the software is being stubborn. When you hook up dvd to smart tv hardware, the TV doesn't always "auto-detect" the device like it does with a PlayStation or a Roku.
You might have to "Add Input" or "Manage Inputs" in your TV's home menu. On Roku TVs, you often have to go to Settings > TV Inputs and specifically enable the "AV" input before it even shows up on your home screen. Don't assume the port is dead just because it doesn't pop up immediately.
Sound Issues: Where’s the Audio?
If you have a picture but no sound, check your RCA cables. The Red and White ones handle the audio. Make sure Red is in Red and White is in White.
If you are using a soundbar connected via ARC or Optical, your Smart TV might be trying to send "Digital Surround Sound" to the bar, but the DVD player is sending "Analog Stereo." Try going into your TV’s audio settings and changing the digital output format to PCM. This is a more basic audio language that everything understands. It usually fixes the "silent movie" problem instantly.
Actionable Steps for a Perfect Setup
If you want to get this done today without a headache, follow this sequence. It's the most efficient way to get your movies running.
- Check for HDMI first. Look at the back of the DVD player. If there is a port that looks like the ones on your TV, buy a $7 HDMI cable and you’re finished in 30 seconds.
- Identify your TV's legacy ports. Look for a yellow circle or a 3.5mm jack labeled "AV." If neither exists, you must buy a converter box.
- Purchase an RCA to HDMI Converter. Ensure it includes a USB power cable. Plug the DVD player (Yellow/White/Red) into the box, and the box into the TV via HDMI.
- Set the resolution. On the converter box, there is often a switch for 720p or 1080p. Set it to 720p first. Some older DVDs actually look better at a lower resolution because the TV doesn't have to work as hard to "guess" where the pixels go.
- Power everything on in order. Turn on the TV first, then the converter box (if it has a switch), then the DVD player. This helps the HDMI handshake complete successfully.
- Update your TV settings. Navigate to the Input/Source menu and label the new connection as "DVD" so you don't have to guess next time.
Physical media isn't dead; the ports just changed. By using a simple converter or checking for a hidden HDMI port, you can bypass the streaming wars and watch what you already own. It's cheaper, and honestly, the tactile feel of putting a disc in a tray is still pretty satisfying.
