Detailed Instructions for Each Solution
Now that you’ve identified the possible solutions to your problem, let’s learn how to carry them out!
Follow the instructions listed below to fix your input-related issues.
1. Try Another HDMI Port
Sometimes, TV ports can become corrupted and, consequently, stop working. This will prevent your TV from recognizing the input source.
So, it’s a good idea to try connecting your input source device to another HDMI port and see if that does the trick.
Unplug your external device from your TV’s initial HDMI port (taking note of which port you use for future reference) before plugging it into another port. Then, change your Vizio TV’s input to display the new HDMI port.
If it works, you’ve found the culprit and can start displaying your external device. Otherwise, proceed to the next recommended solution.
2. Unplug All the Cables & Perform a Soft Reset
Simple hardware glitches can cause your Vizio TV to struggle to recognize your external input source or change inputs.
So, unplugging all the connected devices and soft resetting your TV may be the best course of action to fix this problem.
Step 1: Power off your Vizio TV before unplugging all the cables you can (e.g. HDMI, power cable, VGA, etc).
Step 2: Once 30 seconds have elapsed, reconnect all the cables to your TV.
Step 3: Power on your TV and see if you can display your input source.
Note: If your source device has a USB power cable (e.g. Roku, Fire Stick, Chromecast), remember to plug it into a wall outlet using a USB power adapter instead of plugging it into your TV’s USB port. Using your TV to power your source device may prevent the TV from recognizing it due to the lack of power.
3. Try Using Another Source Device or Cable
If you suspect your TV’s port is working correctly, it’s a good idea to verify its functionality by connecting another source device or cable to it. At times, your source device or cable may be broken, stopping your TV from recognizing that any source device has been connected.
Step 1: Disconnect the initial source device and/or cable from your TV.
Step 2: Connect the other source device and cable to your TV and see the results.
If another source device or cable works with your TV, then you know that the original accessories you were using are the culprit.
4. Your Remote’s Input Button May Be Faulty
If you’re not sure how to change your Vizio TV’s input without a remote, head to the final section to learn how. If you can successfully change the input using that method, then your remote’s broken input button may be the problem.
Try one of the following three methods to fix the issue.
1. Clean the inside of the remote control by following the steps below.
- Remove the battery mount cover on the back of the remote before taking out the batteries.
- If you don’t see any screws in the battery mount, you should be able to pop open the remote by sliding and twisting a thin, firm object (e.g. flat head screwdriver, wine opener’s foil cutter, metal nail file, etc.) in the remote’s horizontal seam.
- Separate the remote’s rubber keypad from the case. Notice the rubber keypad’s conductive contact points and make sure that the input button’s point is in good condition. Then, thoroughly wash the entire rubber keypad using mild soap and water. Once washed and rinse, ensure the keypad is completely dry.
- Use rubbing alcohol and Q-tips to carefully clean the keypad’s buttons and contact points. Then, dry off the keypad with a clean paper towel.
- Next, it’s time to clean the circuit board with rubbing alcohol and fresh Q-tips before drying it off.
- Reassemble your remote, popping the case together to hold everything in place.
- Put fresh batteries into the battery mount, replace the mount cover, and see the results.
Watch the video below demonstrating how to clean the inside of a remote.
2. Change the Vizio TV input without the remote (proceed to the last section for instructions).
3. Purchase a replacement remote.
5. Check & Replace the HDMI Cable If Needed
Like everything else in life, HDMI cables do not last forever. Your cable may be rotting, missing pins, or have a broken connector. Needless to say, this will prevent it from doing its job correctly.
So, say goodbye to your favorite audio-visual cable and buy a working replacement.
I recommend the Amazon Basics High-Speed 4K HDMI Cable as it’s high-quality and durable.
6. Adjust Your Laptop’s Resolution
When connecting your laptop to your Vizio TV, you must ensure that their resolutions are compatible. So, it’s best to check your laptop’s output resolution and ensure it’s supported by your TV.
Follow the directions below or read our article to learn how to change your laptop’s output resolution.
Step 1: Open the Start menu.
Step 2: Navigate to the Settings.
Step 3: Go to System.
Step 4: Click on Display.
Step 5: Open Display Resolution.
Step 6: Select a compatible resolution from the drop-down menu.
Step 1: Head to the Apple menu.
Step 2: Open System Preferences.
Step 3: Go to Display.
Step 4: Click on Resolution.
Step 5: Head to Scaled.
Step 6: Select a compatible resolution.
7. Update the Vizio Firmware
If you suspect that your Vizio TV firmware may be glitching, try updating it. This will rid your TV of any firmware-related bugs and give you access to the latest features.
Follow the instructions below to update your Vizio TV.
Step 1: Hit your Vizio TV remote’s Menu key.
Step 2: Find and open System.
Step 3: Click on Check for Updates. If there are any, download and install them.
8. Factory Reset Your Vizio TV
If you’ve cleaned or replaced all of your TV and source device’s components but still can’t correctly adjust the TV input, you may need to factory reset your TV.
While tedious, this is an effective way to ensure your TV isn’t malfunctioning due to a glitch in the software.
Note: This process will wipe your TV’s data and apps, forcing you to re-enter and re-install them.
With the Remote
Step 1: Click the remote’s Menu button.
Step 2: Under TV Settings, go to System.
Step 3: Scroll down and select Reset & Admin.
Step 4: Click on Reset to Factory Settings.
Step 5: In the pop-up menu, click on Reset.
Watch the video below to learn how to factory reset your Vizio TV with its remote.
Without the Remote
Step 1: Find the control buttons on the back of your TV. With your TV on, simultaneously press the Volume Down (-) and Input buttons until you see a “Reset to Defaults” message on-screen.
Step 2: Then, long-press the Input button for 10 seconds or until a “Memory is being cleared” message appears.
Step 3: Wait for your TV to reboot before setting it up again.
Watch the video below demonstrating how to factory reset a Vizio TV without its remote.
9. Reach Out to Vizio Technical Support
Nothing is going as planned and none of the solutions have fixed your never-ending input-related problems on your Vizio TV.
While I don’t have any more troubleshooting tips to offer, Vizio technical support might.
Bear in mind that Vizio warranties usually only last a year, unless you’ve paid to extend it. If your warranty is expired, you may have to pay for any repairs yourself.

You can reach them via SMS by texting 205-301-3729.
They also have a live chat function.
Finally, you can call one of their skilled agents by dialing (844) 254-8087.
Make sure to provide them with your TV model number and summarize which troubleshooting solutions you’ve already tried.
