Master Samsung TV Remote Input Button Guide: Locate, Change, And Troubleshoot Sources (2026)

The "Input" button on a Samsung TV remote is designated as the "Source" button on classic infrared remotes, whereas 2021 through 2026 Samsung Smart Remotes and SolarCell remotes omit this dedicated key entirely in favor of an on-screen navigation bar or voice control interface.

Understanding how to switch video inputs—whether between cable boxes, gaming consoles, soundbars, or streaming devices—requires knowing which remote model you possess and how the Samsung Tizen operating system manages connected devices.

Locating the Input Button Across Different Samsung Remote Generations

Samsung has altered its remote control philosophy significantly over the past decade. While older models relied on dense arrays of physical keys, modern Eco and SolarCell remotes prioritize minimalist design. Identifying your remote layout is the first step toward seamless input selection.

Standard Infrared (IR) Remotes (The Classic "Source" Key)

Standard Samsung remotes—commonly shipped with Crystal UHD, older Full HD, and budget commercial displays—utilize a direct physical button for switching connections.

• Button Placement: Located at the top right or top left corner of the remote, directly adjacent to or beneath the red Power button.
• Iconography: The button is labeled explicitly with the word SOURCE or marked with an icon depicting a rectangle with an arrow pointing inside it (representing an incoming signal).
• Functionality: Pressing this button repeatedly cycles through available active inputs (HDMI 1, HDMI 2, AV, Component, and Live TV) or opens an on-screen source selection menu.

Modern Samsung Smart Remotes and SolarCell Controls

Starting with modern QLED, Neo QLED, OLED, and The Frame models, Samsung removed the dedicated physical Source button. If your remote features a built-in solar panel on the back, a USB-C charging port, and a minimal button count, it lacks a standard Input button.

• Primary Workaround Key: The Home button (depicted by a house icon). Pressing Home brings up the Smart Hub launch bar.
• Secondary Workaround Key: The Settings/123 or Quick Menu button. On select models, pressing the Number/Color key opens a quick-access overlay with direct input shortcuts.

Operational Insight for Smart Remotes The elimination of the dedicated Source button is intentional. Samsung's automated device detection software (Anynet+) automatically registers when a console or set-top box turns on, prompting the TV to switch inputs automatically or create a dedicated icon on the Tizen Home interface.

How to Switch Inputs on Samsung Smart TVs Without a Dedicated Source Button

If your remote control lacks a physical Source button, switching between connected HDMI ports or external devices is performed through the Tizen OS interface using one of three primary workflows.

Method 1: Navigating the Home Menu Navigation Bar

1. Press the Home button on your Smart Remote to bring up the main dashboard.
2. Press the Left Directional Arrow on the navigation pad to open the left-side main sidebar menu.
3. Scroll down and select Connected Devices (or Sources on earlier Tizen software releases).
4. Select the specific device or HDMI port you wish to view (e.g., HDMI 1: PlayStation 5, HDMI 2: Cable Box).

Method 2: Utilizing the Quick Settings Overlay

1. Press the Settings / Quick Menu button (represented by a gear icon or a multi-function button with numbers/colors).
2. On the lower-third screen overlay, navigate horizontally to the Source / Input tile.
3. Highlight the tile and press the Center Select button to expand the list of active video inputs.
4. Choose your target input port from the pop-up list.

Method 3: Voice Control Commands

Modern Samsung Smart Remotes feature a dedicated Microphone button designed for rapid system navigation. Voice switching bypasses multiple menu layer interactions completely.

1. Press and hold the Microphone / Voice button on your remote control.
2. Speak clearly into the remote using precise commands such as:
   
   
   • "Switch to HDMI 1"
   • "Change input to Nintendo Switch"
   • "Open Connected Devices"
3. Release the Voice button once the command prompt registers on the upper right corner of the screen.

Comparison of Samsung Input Access Methods

The following matrix compares how input selection is executed across various hardware control interfaces found on modern Samsung displays.

How to Change Samsung TV Inputs Without Any Remote Control

If your remote control is lost, damaged, or discharged, you can switch hardware inputs using physical on-body controls or smartphone software integration.

Using the Physical TV Controller (Jog Switch / Function Button)

Every Samsung television includes a physical controller button, often referred to as the TV Control Pad or Jog Switch.

• Location: The controller switch is typically found underneath the bottom bezel in the center (near the standby light), on the lower-right rear panel, or on the right side of the frame.
• Single-Button Operation: Press the single button once to activate the Control Menu on the lower display. Single-press the button repeatedly to highlight the Source / Input icon. Press and hold the button for one second to select it.
• Five-Way Directional Controller: If your TV uses a 5-way joystick switch, press the central button to invoke the menu, push the joystick left or right to highlight Source, and press the center button again to enter the selection screen.

Using the Samsung SmartThings App

Samsung TVs connected to a home Wi-Fi network link directly with the SmartThings ecosystem on iOS and Android devices.

1. Launch the SmartThings application on your mobile device.
2. Select your Samsung TV from the registered device list.
3. Tap the Virtual Remote icon on the screen interface.
4. Tap the Source button tile, or select the Connected Devices card to choose your desired HDMI or AV input port directly from your smartphone screen.

Troubleshooting Input Switching Failures and CEC Conflicts

Input switching issues stem from corrupt HDMI handshakes, misconfigured consumer electronics control (CEC) protocols, or depleted hardware components.

Technical Diagnostic Check If an HDMI port appears dark gray and cannot be selected, the TV processor does not detect an active signal or electrical continuity from the external playback device. Ensure the source device (gaming console, decoder, media streamer) is fully powered on before attempting to switch inputs.

Resolving Greyed-Out HDMI Inputs

1. Disconnect the HDMI cable from both the Samsung TV and the external device.
2. Unplug the power cords of both devices from the electrical outlet for 60 seconds to discharge latent electricity.
3. Re-seat the HDMI cable firmly into the port (preferably HDMI 1 or HDMI eARC/ARC).
4. Reconnect power and switch on the external device before turning on the Samsung TV.

Resolving Anynet+ (HDMI-CEC) Control Glitches

Anynet+ allows Samsung TVs to switch inputs automatically when an external device powers up. If this causes erratic switching:

1. Press Home on your remote and navigate to Settings.
2. Select All Settings -> Connection -> External Device Manager.
3. Toggle Anynet+ (HDMI-CEC) to Off if you want manual input control, or toggle it On if auto-switching has stopped functioning.
4. Execute an Input Auto Detection Reset under the same menu to re-index connected equipment.

Troubleshooting an Unresponsive Remote Input Key

If pressing the Source key yields no on-screen visual feedback:

• Infrared Line-of-Sight Check: Ensure no soundbars, decorative items, or dust obstruct the IR receiver bulb located on the bottom bezel of the TV.
• Smart Remote Re-Pairing Procedure: For Bluetooth SolarCell remotes, stand within three feet of the TV, press and hold the Return/Back button and the Play/Pause button simultaneously for at least three seconds. A prompt reading "Pairing Complete" will appear on screen.
• Power Soft Reset: Hold the physical Power button on your Smart Remote down continuously for 8–10 seconds until the Samsung logo appears on screen, rebooting the internal Tizen operating system.

Frequently Asked Questions

Where is the input button located on a Samsung Smart Remote?

Modern Samsung Smart Remotes do not feature a physical button labeled "Input" or "Source." Inputs are accessed by pressing the Home button, sliding left to Connected Devices, and choosing the desired port.

This design relies on Samsung's Tizen operating system to aggregate all physical ports, streaming apps, and connected devices into a single unified menu rather than using dedicated hardware toggles.

Why is the HDMI source button greyed out on my Samsung TV?

An HDMI port tile appears greyed out when the television's video controller detects no active electrical signal or audio/video handshake from the connected hardware.

To resolve this, verify that the external device is powered on, test a different high-speed HDMI cable, or perform a cold reboot by leaving the TV and source device unplugged from the wall power outlet for one full minute.

How do I change the input on my Samsung TV without a remote?

You can change inputs without a remote by using the physical TV Control button located on the underside or rear of the TV chassis, or by launching the SmartThings app on a phone connected to the same Wi-Fi network.

Pressing the physical TV Control button opens a pop-up menu where you can navigate to the Source icon using single or long button presses.

How do I re-pair my Samsung Smart Remote if the buttons stop switching inputs?

Re-pair a Bluetooth Samsung remote by pointing it at the TV's IR sensor and pressing the Back and Play/Pause buttons simultaneously for 3 to 5 seconds.

A connection graphic will display on the top section of the screen indicating that the remote has successfully re-established its Bluetooth connection with the television.
