I had previously tested a few universal remotes for my TCL TV, and the TV randomly gave me a black screen almost three times during my testing. Because I review a lot of products with my TCL TV, it was obvious that this would be a problem later on.
I contacted TCL support, did a lot of online research, and tried a slew of fixes. I meticulously documented what I discovered in order to create this guide to assist you in repairing your TCL TV that has gone black.
Restart your TCL TV to repair it if it has a black screen. If this does not resolve the problem, replace the HDMI cables. I’ve also gone into detail about how to Reset your TCL TV. When it comes to delivering high-quality audio and video, the TCL TV is a one-stop shop.
However, there is a common issue that most users face: the screen going black. Don’t worry if this happens; there is a solution. There are numerous reasons why your TCL TV screen may not display video even if you can hear the audio.
If the screen on your TCL Roku TV has gone black but the audio is still working, it is most likely due to a loose cable connection or a hardware issue affecting your TV’s LED lighting.

The problem is resolved by unplugging the TV from all cable connections, including power, and then plugging it back in after 5-10 minutes. However, if it is an LED issue, you will require the assistance of a professional.
POSSIBLE REASONS FOR TCL TV BLACK SCREEN
A black screen can be an indication of a more serious underlying issue, and determining what that issue is is the first step in troubleshooting. One of the most likely causes of this is a problem with the HDMI cable that outputs the display from whatever device you are using the TV with.
Another possibility is that the TV’s backlight is failing. Most televisions rely on a backlight to illuminate the image, and a problem with the backlight can result in black screens.
Another possibility is that there is a software bug in the TV or the device you are using with it. But don’t worry, with this guide, I hope to make repairing your TV as simple as possible.
1. POWER CYCLE THE TV AND REMOTE
The restart is the first step in any troubleshooting guide. In this case, we’re attempting a power cycle, which is a type of restart.
A power cycle, as the name implies, is the process of unplugging or removing the power source, turning off the device for up to a minute, and then plugging everything back in.
A power cycle can resolve issues that arose as a result of an unintentional setting change, either made by you or performed automatically, that caused the TV to go black.
To power cycle your TCL TV:
- Turn off the TV. Wait until all the status lights on the TV go off.
- Unplug the TV from the power outlet and wait for 1-2 minutes.
- Plug the TV back in and start it up again
To power cycle the remote:
- Remove the batteries from the remote.
- Wait for 1-2 minutes.
- Insert the batteries back in.
To see if you’ve resolved the problem, try to recreate what you were doing when the black screen appeared. Use the TV normally while keeping an eye out for the black screen to reappear.
2. POWER CYCLE THE TV USING AN ALTERNATE METHOD
If the method described above does not work, there is another way to power cycle the TV.
You’ll need a paperclip or something similar to get started. Then:
- Unplug the TV from the wall and turn it off.
- Locate the reset button on the TV’s side. It appears to be a tiny hole into which only a paperclip can fit.
- Hold down the reset button for at least 30 seconds.
- Restart the television.
Recreate the exact situation and confirm that the problem has been resolved.

3. RESTART THE TV USING THE REMOTE
This method is applicable only for TCL Roku TVs. You can restart the TV by pressing a certain key combination on your remote.
This combination is pretty easy to execute and is detailed below.
- Press Home five times
- Press Up once
- Press Rewind twice
- Press Fast forward twice
Once you correctly complete the combination, the TV will begin its restart. Use the TV as you would normally after the restart and look if the issue persists.
4. CHECK THE CABLE CONNECTIONS
I previously stated that a loose connection or damaged cables could be the cause of a black screen on any TV. Examine the back of the TV to ensure that all connections are secure.
If your HDMI cable is getting old, I recommend replacing it. Even if you are using the stock HDMI cable that came with the TV, purchasing a new one from a reputable brand such as Belkin is a good idea.
I’d go with the Belkin Ultra HD HDMI cable. It’s gold-plated, so you can be sure it’ll last forever, and it has fast speeds for a lag-free display.
5. UPDATE YOUR FIRMWARE
Since TVs switched to the Android ecosystem, software on TVs has gotten more frequent updates, and the TCL TV is no exception.
Software updates are constantly fixing major and minor issues, so it is a good idea to update your TV as well. A software update for Android TVs updates the TV’s firmware, making it simple to check for and install firmware updates.
To update your TCL Android TV:
- Navigate to the Settings menu by pressing the Home button on the remote.
- Select More Settings from the Settings menu.
- Select Device Preferences>About.
- System Update should be selected.
- Select Network Update from the drop-down menu that appears.
- The TV will search for and download any available software updates.
- When it’s done, click OK to confirm.
6. TWEAK FAST START OPTION
People on online forums reported that they were able to fix their black screen by enabling or disabling the TCL TV’s Fast Start option.
Enabling it if it was previously disabled or disabling it otherwise is something worth investigating, and I will walk you through the process below.
Follow these steps for the TCL Roku TV:
- On the Roku TV remote, press the Home button.
- Navigate to System > Settings.
- Select Quick TV Start.
- Enable or disable Fast TV Start as needed.
For TCL Android TVs:
- Open the Settings menu.
- Select Power
- Change the “Instant power on” setting as applicable.
Restart the TV and check if the issue has been solved.
7. FACTORY RESET THE TV
A factory reset should be your last resort, primarily because it will erase all settings and logged-in accounts from the TV. You’d also have to repeat the initial setup and reconnect to your WiFi network.
To perform a factory reset on your TCL Roku TV, follow these steps.
- Choose Settings.
- Scroll down and select System.
- Go to System Settings > Advanced > Factory Reset.
- Choose Factory Reset All Settings.
- To proceed with the factory reset, enter the code displayed on the screen.
To reset everything to factory defaults on an Android TV,
- From the home screen, press the settings button on the remote.
- Navigate to More Settings > Device Preference > Reset.
- Choose Factory data Reset.
- Select Erase Everything.
- Enter the PIN displayed on the screen and press OK.
TCL televisions are excellent value for money. It is an excellent choice for anyone looking for a 4K TV but does not want to splurge on a Sony or an LG while not sacrificing features. The TV isn’t the only thing that can break down from time to time.
The Roku remote occasionally fails to function properly, but this is a simple fix. Overall, TCL’s Android TVs and newer Roku TVs are excellent options for your first smart home entertainment system.
The fact that your TCL TV screen has gone black is not cause for concern. You can try restoring your TV screen with the above-mentioned simple fixes. However, if none of the suggestions work, contacting a technician should be your next step.
