How To Fix TCL Roku TV Black Screen
Restart Your TV
For a restart, we use a certain Key combination on TCL Roku TV remote.
The whole screen will be frozen for a while and reboot your TV. This simple reboot is really helpful in resolving the black and flickering screens.
Change Batteries on your Remote
You must change your remote control batteries. Because a fresh set of batteries might be all that you need to power your TV back on your TV
Plug in and Plug out | Power cycle
Most of the users will be able to resolve the black screen issue by following this approach.
Power cycling the TV can help resolve issues such as a frozen screen, a malfunctioning remote control, or problems with the TVs connected to the internet.
Did you know?
An interesting thing to note about TCL Roku TVs is that they feature a built-in troubleshooting tool called “TV Diagnostics” which allows users to quickly and easily identify and fix common issues. This tool can be found under the TV’s settings menu and can help users troubleshoot and fix issues such as a black screen, connectivity problems, and more.
Additionally, TCL Roku TVs are equipped with a built-in power cycling feature which can help troubleshoot issues that may be caused by the TV’s software. It’s also worth noting that some apps may cause the black screen problem, in that case uninstalling and reinstalling the app can help to fix the issue.
Check the power Source
Sometimes, you keep on the power button from your remote but your TV shows a black screen only. The reason could be that your TCL Roku TV hasn’t been turned on. You can verify this by checking the power indicator on your TV.
You must check the power outlet and ensure that it is delivering power to the source at adequate voltage. If the power outlet is faulty, change it before it may damage your TV. In most cases, TCL TV causes flickering due to bad power.
Check If Power cord is plugged in correctly
Locate the power cord on the back of the TV and check that it is securely plugged into the power port on the TV.
Now, Check that the other end of the power cord is plugged firmly into a working electrical outlet.
Because sometimes cord is faulty or it becomes loose which doesn’t make the connection intact and you may see a flickering screen on your TV.
So, either change your cord or fix the ends of the cord and reconnect both ends with the TV and socket.
If the TV still doesn’t turn on, check to see if the outlet has a switch and make sure it is turned on.
Check HDMI Cable Connection
HDMI input cables become faulty over time. That’s why you observe a black screen with no sound on your TV. You can perform a few steps to verify whether the issue is with your HDMI cable connection.
Make sure the TV and the device you are connecting (such as a cable box or gaming console) are both turned on and set to the correct input. Your TV has various HDMI inputs, so make sure that the correct HDMI input is being used.
Update Your TV Firmware
Updating firmware resolves many unknown issues because an older version causes issues that are only related to compatibility.
Updating the firmware on a TCL TV is a simple process that can be done through the TV’s menu. Here are the general steps you can follow to update the firmware on your TCL TV:
Tweak Fast Start Option
We had observed many users resolving their issues by only reversing the option in case of a Black screen on their TCL TVs. If you have enabled this option, I would recommend you disable it.
Factory Reset the TV
Factory Reset is usually applied when you have tried all the above methods and you haven’t found the solution yet. Performing a factory reset on a TCL TV will erase all of the custom settings, channels, and applications that have been added and restore the TV to its original factory settings.
Issue with TCL TV backlight
When you turn on your TV, see a power indicator on your TV, and sound is also coming through your TV. But, there is no video on your screen. This issue is generally called Backlight consisting of LED lights.
I recommend you check the following points before moving forward.
Now, bring a flashlight close to your TV screen and see if there are controls and text visible to you. You can also use your remote control to change the settings and witness moving prompts and settings. If you see text on your screen, this issue is with LED lights of TV and it is not a big issue. You can implement one of the two steps below.
- Exchange In-warranty TV
- Replacing TCL LED Backlight Strips
Exchange In-warranty TV
Chose a new TCL TV if your TV is under warranty. TCL will replace free of cost and you don’t even have to pay a technician fee as well.

By following the troubleshooting steps outlined in this FAQ, you can try to resolve the issue on your own. These steps include checking that the TV and any connected devices are powered on and set to the correct input, ensuring that the HDMI cable is securely connected, using a different HDMI cable or port, checking for firmware updates, unplugging the TV and connected devices and resetting the TV to factory settings.
