One common issue is where your TCL Roku TV has sound but doesn’t show pictures. Fortunately, sometimes the problem is minor, meaning that you can fix it without calling a technician.

However, if it is an LED problem, you will need assistance from a professional.

How to fix a black screen on a TCL Roku TV?

Getting a black screen on your TV can be frustrating. However, some of the causes are minor and can be solved by simple DIY repair.

Try out these solutions one by one until the issue is resolved:

1. Reboot your TV

Rebooting is a solution that is given almost every time as a fix for devices, particularly routers and phones. And while you might be skeptical, it can work just as well for your TV.

A reboot will restart all the hardware and software in your device. As a result, any minor glitches that could be causing the black screen will be fixed, allowing you to enjoy quality pictures again.

To reboot your TCL Roku TV, simply unplug it from the power outlet (without powering off), wait for about one minute, then plug it in back and power it on.

This procedure will work most of the time, fixing any minor problems affecting your TV.

2. Factory reset your TV

Did the reboot not work? The issue could be a tad more serious, for example, corrupted settings on your TV. In such a case, a factory reset can help fix the issue.

There are two ways to reset your TV:

  • Through the settings menu
  • Through a hard reset

Since you cannot access the menu without pictures showing, the hard reset is the option to follow.

  • Go to the back panel or side panel of your TV (where HDMI and other connector ports are located).
  • Find the hard reset button and press it (you might need a sharp-pointed object for this).
  • Hold the button for about 12 seconds then release it (your TV will power off).
  • Power on the TV and complete the guided setup procedure

With a factory reset, all settings including network settings, and saved data will be removed. Therefore, you will have to set up your Roku account all over again when you are done.

3. Check the cable connections

Are you connecting the Roku cable box to your TCL TV? Loose cable connections could be the problem.

HDMI cables can be especially problematic if they are faulty, so check to ensure that they are not damaged. Loose or damaged power cables could also be causing glitches to your screen, causing the picture problem.

If the HDMI cable seems is faulty, consider getting the iVanky high-speed braided cable. It can stream HD content without lagging and it is braided meaning that there are minimal chances of damage. The cable is available on Amazon.

4. Update your TV firmware

TCL Roku TVs come with firmware that needs to be up-to-date for your device to function optimally. Therefore, if you are experiencing a black screen with sound, the issue might have to do with out-of-date firmware.

To fix the problem:

  • Go to the settings menu on your TV
  • Navigate to systems update
  • Select the update option to download and install the latest firmware

Now, this option will only work if the black screen does not affect the menu. However, if the menu is not visible, you will need to get in touch with TCL customer support. They will then guide you on how to troubleshoot and fix the problem.

Conclusion

Your TCL TV screen has gone black, but the sound still works – what can you do? Being interrupted from enjoying your favorite programs can be frustrating.

Luckily, with the above solutions, you can be able to fix most of the issues causing the black screen.

However, if the problem persists, your next best option is to call customer support. Alternatively, you should take your TV to an authorized TCL repair center for servicing.
