Are you having an issue with your TCL Smart TV where you have sound but no picture? You’re not alone. This is a common problem, and there are a few things you can try to fix it. In this blog post, we’ll cover five potential solutions for fixing this issue.

What is TCL Smart TV?



TCL Smart TVs are LED-LCD TVs with a built-in operating system that allows you to access streaming services, apps, and other features. They come with a variety of picture settings, and you can adjust them to suit your needs.


If you're experiencing issues with your TCL Smart TV, it's likely due to one of the following: power cycling your TV, checking the cable and connections, updating the firmware, resetting your TV, or a problem with the TCL TV screen. Let’s look at each of these potential fixes.

Fix 1: Power Cycle Your TV


Power cycling your TV is the first step in troubleshooting any issue. To do this, unplug the power cord from the wall outlet for 30 seconds and then plug it back in. After a few moments, your TV should power on and display a picture.



  • Unplug the power cord from the wall outlet.
  • Wait 30 seconds.
  • Plug the power cord back into the wall outlet.
  • Wait a few moments, and then turn on the TV.



    • If the picture still doesn't display after power cycling your TV, it's possible that there is a deeper issue at hand. Try checking the cable and connections (covered below) or updating the firmware before attempting a reset.

    Fix 2: Check the Cable and Connections


    If the picture still won't display after power cycling your TV, there may be a problem with the cable or connections. To check, start by determining what type of cable connection you are using. The most common types are HDMI, composite, and component.



  • HDMI: HDMI cables are used to connect your device to the TV. They can handle a variety of audio and video signals and provide the best picture quality.
  • Composite: Composite cables are usually used to connect older devices to the TV. They can only handle a single video signal, so the picture quality isn’t as good as with HDMI.
  • Component: Component cables are similar to composite cables but can handle a few separate audio and video signals. They are usually used to connect gaming systems and home theater systems.


    • Troubleshooting Steps for Checking Connections


  • Check the cable connections. Make sure all the cables are securely plugged into the TV and the other device.
  • Check the settings. Make sure the video and audio settings are configured correctly on the TV and the other device.
  • Try a different cable. If the problem persists, try using a different type of cable.

    • Fix 3: Update Firmware


    If you’re still experiencing issues after checking the cable and connections, it may be time to update the firmware on your TCL Smart TV. Firmware updates can fix bugs and improve the performance of your TV.



  • Check for updates. Open the settings menu on your TV and select “Updates.” Then, select “Check for updates.”
  • Download and install the update. Once the update is found, follow the on-screen instructions to download and install it.


    • Pros and Cons of Updating Firmware


    Updating the firmware on your TCL Smart TV can fix a variety of issues, but it can also cause new issues. If you’re unsure whether it’s worth the risk, consult with a professional.

    Fix 4: Reset Your TV


    If you’re still experiencing issues after updating the firmware, the next step is to reset your TV. Resetting your TV will wipe out all of its settings, so make sure to back up any important information first.



  • Open the settings menu.
  • Select “Reset.”
  • Follow the on-screen instructions to reset your TV.


    • Resetting your TV can fix a variety of issues, such as freezing or lag. After resetting, you’ll need to reconfigure your settings, but this can be a good opportunity to optimize your TV for the best picture and audio quality.

    Fix 5: Problem With TCL TV Screen


    If you’re still experiencing issues, it’s possible that there is a problem with the TCL TV screen itself. In this case, you’ll need to troubleshoot the issue to determine the cause
