Change Input Element TV: How to Fix It

Updated 7 November 2026 · Standard formula, shown below

If your TV is stuck on the wrong input source (HDMI 1, AV, etc.), you can change it using the “Input” or “Source” button on your remote or TV, or by using the TV’s on-screen menu. This article explains all the ways to switch inputs, why the TV might not respond, and how to fix common input-related problems.

What Is an Input Element on a TV?

An input element on a TV is the connection port (or the software that manages it) that receives a video and audio signal from an external device. Common inputs include HDMI, USB, component, composite (AV), and coaxial. When you press the “Input” or “Source” button on your remote, you are telling the TV to switch to a different input element, which changes the signal source it displays. The TV’s input menu is the on-screen list of all available ports, and you can select a different one to change what appears on the screen.

How to Change the Input on Your TV

There are several ways to change the input on a TV, and the exact method depends on your TV model and remote. Here are the most common methods:

Using the “Input” or “Source” button: Most remotes have a button labeled “Input,” “Source,” or a square with an arrow pointing inward. Press it once to open the input list, then use the arrow keys to highlight the desired input and press Enter/OK.
Using the TV’s on-screen menu: Press the “Menu” or “Home” button on your remote, navigate to “Settings” or “System,” then look for “Input,” “Source,” or “Channel” options. From there, you can select the input you want.
Using a physical button on the TV: Many TVs have a physical button (often labeled “Input” or “Source”) on the side or bottom of the TV. Press it repeatedly to cycle through inputs, or press and hold to open the list.
Using voice commands: If your TV has a built-in voice assistant (e.g., Alexa, Google Assistant), you can say “Switch to HDMI 2” or “Change source to AV” to change the input.
Using a universal remote or smartphone app: If you have a universal remote or a TV manufacturer’s app on your phone, you can often change inputs from the app’s remote interface.

Why Won’t My TV Change Input?

If your TV is not responding to input changes, there are several common causes:

Remote issues: The remote may have dead batteries, be out of range, or have a stuck button. Try replacing the batteries and pointing the remote directly at the TV’s IR receiver.
TV is frozen or unresponsive: A temporary glitch can cause the TV to freeze. Unplug the TV from power for 30 seconds, then plug it back in and try again.
Input source is not active: If the device connected to that input is turned off or not sending a signal, the TV may skip that input or show a “No Signal” message. Turn on the device and try again.
HDMI-CEC conflicts: Some TVs have HDMI-CEC (Consumer Electronics Control) enabled, which can cause the TV to automatically switch inputs when a device is turned on or off. This can sometimes override your manual input selection. You can disable HDMI-CEC in the TV’s settings (often under “System” or “General”).
Faulty port or cable: A damaged HDMI port or cable can prevent the TV from recognizing the input. Try a different port or cable.

How to Choose the Right Input

To choose the correct input, you need to know which port your device is connected to. Most TVs label their ports with numbers (HDMI 1, HDMI 2, etc.) and sometimes with names like “Game” or “ARC.” Here’s how to identify the right input:

Check the port labels: Look at the back or side of the TV for labels next to the ports. For example, if your cable box is plugged into the port labeled “HDMI 1,” select HDMI 1 on the input menu.
Use the TV’s auto-detection: Many modern TVs automatically detect when a device is connected and may show a pop-up asking you to switch to that input. If you miss it, you can still manually select it.
Label your inputs: Some TVs allow you to rename inputs (e.g., “Blu-ray,” “Game Console”) to make them easier to identify. This is usually found in the input settings.

Common Input Problems and Fixes

Here are some common input-related problems and what to do about them:

No signal on a specific input: If the TV shows “No Signal” on the correct input, check that the device is powered on, the cable is firmly connected, and the device is outputting video (some devices have multiple output modes). Try a different cable or port.
Input list is missing an option: Some TVs hide unused inputs. You may need to enable them in the TV’s settings under “Input” or “Source” management.
TV keeps switching back to a previous input: This is often caused by HDMI-CEC or a device that is sending a “wake” signal. Disable HDMI-CEC or turn off the device that is causing the automatic switch.
Remote’s input button does nothing: Try using the TV’s physical buttons or a smartphone app. If that works, the remote may need to be re-paired or replaced.

TV Input vs. TV Channel: What’s the Difference?

TV inputs and channels are two different ways to receive content. A channel is a broadcast signal received via an antenna, cable, or satellite. An input is a wired or wireless connection from an external device (like a streaming stick, game console, or DVD player). When you change the input, you are telling the TV to display the signal from that specific device, not a broadcast channel. Some TVs have a “TV” input (or “Antenna”) that shows broadcast channels, but most modern TVs separate these into different menus.

Frequently Asked Questions

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

If you don’t have the remote, look for a physical button on the TV itself. Many TVs have a button labeled “Input” or “Source” on the side or bottom. Press it to cycle through inputs, or press and hold to open the input list. If your TV has a joystick-like button, press it to open the menu and navigate to the input option.

Why is my TV stuck on one input and won’t change?

First, try unplugging the TV for 30 seconds and plugging it back in. If that doesn’t work, check if the remote is working (try the physical buttons on the TV). If the TV still won’t change, it may be a hardware issue with the input board or the main board, and you may need to contact a professional.

How do I set my TV to the correct HDMI input?

Press the “Input” or “Source” button on your remote, then select the HDMI port that your device is connected to (e.g., HDMI 1, HDMI 2). If you’re not sure which port, try each one until you see the device’s picture.

What does “Invalid Input” mean on a TV?

“Invalid Input” usually means the TV cannot recognize the signal from the selected input. This can happen if the device is off, the cable is faulty, or the device is not compatible with the TV’s resolution. Check the device and cable, and try a different input.

Can I change the input using my cable remote?

Some cable remotes have an “Input” or “Source” button that can control the TV if programmed. If your remote doesn’t have one, you can program it to act as a universal remote, or use the TV’s own remote.

How do I change the input on a Samsung TV?

On Samsung TVs, press the “Source” button on the remote (it looks like a rectangle with an arrow pointing in). This will open the source list. Use the arrow keys to select the input and press Enter. You can also go to Settings > General > External Device Manager > Input Source to manage inputs.
