Before you begin: what channels are on LG Smart TV by signal source
What channels are on LG Smart TV depends on your signal source: over-the-air channels appear after a broadcast aerial is attached to the coaxial port on the back of the set and the TV runs an auto-tuning scan. If you want to access free local broadcasts, you will need to connect antenna to LG smart TV by screwing the coaxial cable into the "ANT/CABLE IN" jack, navigating to Settings > All Settings > Channels > Channel Tuning, and selecting "Auto Tuning" with "Antenna" chosen as the source. This process pulls in every free local station the receiver can lock onto. A weak signal is often fixed by moving the aerial higher or near a window. If you want to understand the full method, you should read the article on how to connect a TV antenna to a smart TV, which explains the setup in detail. The TV's tuner only decodes unencrypted broadcasts, so you cannot watch encrypted cable channels on LG TV without a box, because those scrambled signals require a provider-supplied decoder.
Connecting a set-top box creates a different path for channels. You connect cable box to LG smart TV by running an HDMI cable from the box's output to any HDMI input on the television. After both devices are powered on, the input button on the remote switches the display to that port. A blank screen means the handshake failed; you can fix no signal on LG TV with cable box connected via HDMI by confirming the box is fully booted, the HDMI plug is pushed all the way in, and the on-screen input label matches the physical port. Some setups skip the box and use a direct coaxial line from the wall. You connect cable to LG smart TV by screwing that line into the "ANT/CABLE IN" port and running a channel scan. This method only finds unencrypted channels the provider leaves open, which is a limited list in most areas.
Input confusion is a common source of missing channels. The television can jump away from the correct source if a connected device sends a stray signal. You can stop LG TV from switching inputs automatically by opening the settings menu and turning off "HDMI CEC" or the "Simplink" function. Disabling this stops other hardware from hijacking the screen. The input list also benefits from clear labels, which the TV allows you to edit so each port shows a recognizable name instead of a generic number.
Game consoles deliver streaming channels and disc playback through the same HDMI path. You connect PS4 to LG smart TV by plugging the console into an HDMI port, switching the television to that input, and letting the console detect the display resolution. The TV's game mode then reduces lag for a smoother picture. This connection also turns the console into a hub for subscription-based channel apps that run directly on the PlayStation.
The single most important fact about channel sources on this platform is that the built-in tuner and the HDMI ports operate as completely separate ecosystems, and no amount of scanning will merge them. A channel scan only fills the live TV list from the coaxial input. Every HDMI device lives on its own tile, and its content never appears in the tuner's channel grid. This separation means you must always know whether the program you want is coming through the aerial socket or through an external box, because the TV will never combine those worlds into one seamless guide.
Getting free over-the-air channels with an antenna
Live local news, sports, and network shows arrive without a monthly bill when you connect a standard TV aerial to the RF (coaxial) input on your LG set. Once the receiver is firmly attached, use the remote to open the Settings menu, then navigate to All Settings, then General (on some models), then Channels or Broadcasting. Select the option to scan for available stations. The process to scan channels on LG smart TV models is essentially the same across recent operating system versions. The menu label may read "Auto Tuning" or "Channel Tuning" depending on your year of manufacture.

Missing stations after a finished scan often point to signal strength rather than a hardware fault. Common culprits include a poorly positioned receiver, interference from nearby electronics, or a loose connection at the back of the TV. When you troubleshoot an LG TV antenna scan not finding all channels, start by moving the reception device closer to a window or higher up on a wall. Then run a new scan from the same menu. Most LG sets will store and label the found channels automatically. You can switch between them using the channel up/down buttons without needing a separate remote. For a complete walkthrough on the physical setup, you should consult the guide on how to hook up antenna to LG smart TV.
Getting broadcast television working is the only setup that relies on a coaxial connection and over-the-air signals. Every other external device uses a different physical pathway into the TV, which changes the steps you follow on screen. The one sentence that separates this setup from every other guide is: the antenna input is the only port that requires you to run a channel scan after plugging in the cable, because the TV must decode raw broadcast frequencies into a watchable channel list.
Connecting a disc player uses the same core logic as any modern HDMI device. To hook up a DVD player to my LG smart TV, plug one end of an HDMI cable into the player’s output and the other end into any open HDMI port on the set. Turn on the player, then press the Input or Source button on your LG remote. Select the HDMI port you used from the on-screen list. The TV recognizes the player instantly and displays its menu without any additional scanning or tuning.
Older game consoles require a different cable type because they were built before HDMI became standard. To hook up a PlayStation 2 to a smart TV, locate the console’s composite AV cable with its red, white, and yellow connectors. Match those colored plugs to the corresponding inputs on the back or side of the LG panel. Some newer LG models omit the dedicated composite jacks and instead include a breakout adapter that plugs into a 3.5mm AV input. After connecting, press the Input button and choose the AV or Composite source to see the console’s output.
Connecting a computer or laptop turns the LG screen into a large wireless or wired display. For a Windows machine, press the Windows key and the K key at the same time, then select your TV from the list of available wireless displays. On a Mac, click the Control Center icon in the menu bar, choose Screen Mirroring, and pick the LG set. A wired connection using an HDMI cable works identically to the DVD player setup. The computer detects the TV as a second monitor, and you can adjust the display arrangement in your system settings.
Setting up a cable or satellite box combines the physical connection of an HDMI device with the channel-changing behavior of an antenna. Connect the box to any HDMI port on the LG panel, then switch to that input. Channel surfing now happens entirely through the cable box’s own remote. The LG tuner stays out of the process because the box handles all signal decoding internally. You never need to run a channel scan on the TV itself for this setup to work.
Several connection methods share the same fundamental steps of identifying the correct input port and selecting that source from the Home screen. These tasks, such as hooking up a antenna, a DVD player, or a game console, follow a similar process. They differ only in the device name and the type of cable it uses. Choose the one that matches the equipment you own and follow the connection sequence for its specific port: HDMI, composite, or coaxial.
Adding streaming apps and live TV services
Adding a streaming channel starts when you press the Home button on your remote and navigate to the LG Content Store. This marketplace holds apps for services like Netflix, Hulu, or Paramount+. You can add YouTube TV to LG smart TV just like any other app. Search for it in the store, install it, and sign in with your account to catch live sports and news from a cable-replacement service. If you ever need to manually bring in a missing app, you will want to read the article on how to "add a channel on LG smart TV" so that no streaming option is left out of your lineup.
Watching over-the-air broadcasts requires a different path. You can watch live TV on LG smart TV by plugging a coaxial cable from an antenna into the back of the set. Then run the auto-tuning function from the Settings menu under "Channels." That same scanning process is how you get local channels on LG smart TV. The tuner searches for available broadcast stations in your area and saves them to a numbered list.
Finding the CBS channel on an LG smart TV depends entirely on your setup. A connected over-the-air receiver will display it as a numbered station after your scan finishes. The streaming version requires you to install the Paramount+ app, which carries live CBS in many markets. No single button delivers both versions; the source determines the path.
Niche programming lives inside the app store. You can get cowboy channel on smart TV by searching the LG Content Store for "Cowboy Channel" or its associated streaming app. Rural sports and rodeo events arrive through that dedicated application rather than through a traditional channel scan.
The set merges the broadcast signal and the app-based version of a station into one seamless row on the home screen ribbon.
Displaying your own photos and camera feeds
Your LG Smart TV can do more than just play streaming shows and live broadcasts. It can also turn your living room into a personal gallery or a security monitoring hub. A USB drive with vacation photos plugs directly into the TV’s port. Navigate to the Media Player app to put pictures on my LG smart TV without any extra software. For a wireless approach, you can use screen mirroring or the LG Gallery+ app with Google Photos integration. That connection lets you upload photos to LG smart TV from your phone over the same Wi-Fi network. Sharing recent snapshots with the whole family becomes effortless. Home security is another use case. Owners of a compatible camera system can view blink camera on LG smart TV by checking if a compatible app is available in the LG Content Store. Linking your account lets you check the front door feed while cooking dinner. These options are not traditional “channels.” They are personal media sources accessed through specific apps or USB inputs. They remain distinct from the broadcast, cable, or streaming channels you might normally watch. Always ensure the TV’s software is up to date in Settings > Support > Software Update. This guarantees compatibility with the latest camera apps and photo file formats.
