How to Fix Black Screen Error on TCL Smart TV
The black screen issue may occur on your TCL Smart TV due to a simple or complicated reason. Before opting for help from a technician, make sure to resolve the issue yourself by following the simple troubleshooting fixes given below.
Check the Power Cable and Socket
Power cables play a vital role in the black screen issue. If you face a black screen issue on your TCL TV, the first and foremost thing to check is whether the cables are securely connected to the power socket. Any loose connection between the TV and the power outlet will prevent the flow of power and thus lead to the black screen issue. So, ensure that the cable is connected tightly to the socket without any loose connection.
If the cables are connected properly, and you are still facing the issue, try plugging the TV’s power cable into a different power socket to find out the problem.
Verify the HDMI Cables
Another major cause of the black screen issue is the damaged or loose HDMI cables. If you have connected your TCL TV via HDMI, you must ensure the connections are proper and secure. Connecting the cables to the wrong HDMI port will display the TV with a black screen. To resolve this issue, check with the following conditions.
- If the HDMI cables are connected loosely to the HDMI port of the TV, without any delay, unplug the cable from the TV and re-plug it properly without any loose connection.
- A faulty HDMI port will not allow the TV to function properly and thus result in the TCL Roku, Android, Google, and Fire TV or black screen issue. So, try connecting the cables to different HDMI ports and resolve the issue by yourself.
- Another possibility is a faulty or damaged HDMI cable connected to the TCL Smart TV. This results in the break of the flow of pictures/video, and thus you may get a black screen on your TV.
- Ensure that the input of the TCL TV is changed to the right HDMI port you have connected to the TV. If you’re changing the input to the wrong HDMI port number, you may face the black screen issue.
By performing these functions with the HDMI cable, the black screen issue might be solved. If you still face the issue, get to the next troubleshooting method.
Check the Backlight Settings of TCL TV
If your TCL Smart TV is turned On, but there is no picture displaying on the screen, then this is due to the backlight failing on TCL TV. If the backlight is damaged, there will be no light to illuminate the images, thus will cause a black screen. To check so, follow the below steps.
1. Turn On your TCL TV and point a flashlight towards your Smart TV screen.
2. If your TV backlight is working well, you will get the image on the TV screen.
3. In case you find any dull or blurred image on the screen, then confirm that the problem is with the TV’s backlight.
Once you confirm the defect is with the backlight, it can be solved by replacing the LED strips on the TV screen. Since it is a risky process, it is advised to reach out for help from a technician to get the issue fixed.
Power Cycle your TCL Smart TV
One of the most effective fixes to solve the black screen issue is power cycling your TCL Smart TV. Power cycling is simply unplugging or removing the power cables from the power outlet and replugging them back into the socket. Doing so can clear the temporary bugs, errors, and internal glitches in your TCL TV. The power cycling process is the same as that of a soft reset, and here’s how to do it.
1. Turn Off your TCL Smart TV and unplug the power cable from the power socket.
2. Rest the TV unplugged for 2-3 minutes and plug back the TV cable into the socket.
3. Press the Power button on your remote to turn On the TV.
Now, the black screen issue might be solved on your Smart TV.
Adjust the Picture Settings
Incorrect or messed up picture settings can cause the black screen issue on your TCL TV. Navigate to the picture settings of your TV and check the brightness, contrast levels, and also the other picture settings. If these settings are too low, increase the brightness and contrast levels on your TV to see if the problem gets solved.
This change will have a major impact on solving the black screen issue. If you are still facing the problem, head over to the next troubleshooting method.
Enable or Disable the Fast Start Option
If you own a TCL Roku or Android TV, you have the added advantage of resolving the black screen issue by enabling and disabling the Fast Start option on your Smart TV. Follow the below steps to tweak the Fast Start option on the TCL TV.
To Disable Fast Start on TCL Roku TV
1. Grab your Roku remote and press the Home button.
2. Go to Settings and select System from the drop-down menu.
3. Look for the Fast TV Start option and tap on it.
4. Now, toggle the switch and turn Off the feature to save your changes.
To Disable Fast Start on TCL Android TV
1. Fetch your TCL Android remote and hit the Home button.
2. Choose Settings and select the Power option.
3. Adjust the Instant Power On settings and restart your TCL Smart TV.
Now, check if the problem is solved on your TV.
Update the TCL Smart TV
At times, every Smart TV, including the TCL TV, will release new software to fix the bugs and to improve the TV’s performance. A TCL Smart TV with old firmware will lead to a black screen issue. So, it is mandatory to check for the available updates and update the TV to the latest version frequently.
Since TCL TV comes with a different OS, the steps to update the TV firmware vary accordingly. You can update the TV either manually or automatically. Below are the steps to update the TCL TV manually via TV settings.
TCL TV | Update Steps |
---|---|
TCL Roku TV | Home button → Settings → System → System Update → Check Now → OK → Update Now. |
TCL Android TV | Home button → Settings icon → More Settings → Device Preferences → About → System Update → Network Update → OK. |
TCL Google TV | Profile icon → Settings → System → About → System Update → Network Update Download. |
TCL Fire TV | Settings → Device & Software → About → Check for Updates → Install Update. |
Replace the T-CON Board of your TV
A T-CON is a timing control circuit board that controls the timing of the video signals and is responsible for creating the image on the TV screen. If the T-CON board on the TV is damaged or broken, you cannot see any image on your TV. Instead, you will get a shapeless line, images, or a grey and black screen.
In this case, you can replace the T-CON board with a new one from the online stores. Since it is a risky process, you can opt for a technician to change the T-CON board on your TCL Smart TV. After replacing the T-CON board, the problem should be solved on your TV.
Reset the TCL TV
A reset should be the last option to resolve the black screen issue because a factory reset will wipe out all settings and the stored data on your TCL Smart TV. Though factory resetting is risky, you can try it once before seeking help from customer support. Resetting the TCL Smart TV can be done with and without using a remote controller, and below are the steps to reset your TCL TV using a remote.
TCL TV | Factory Reset Steps |
---|---|
TCL Roku TV | Home button → Settings → System → Advanced System Settings → Factory Reset → Factory Reset Everything → Enter Reset code → OK. |
TCL Android TV | Settings button → More Settings/System → Device Preferences → Reset → Factory Data Reset → Erase Everything → PIN code. |
TCL Google TV | Settings menu → System → About → Reset → Factory Reset → Erase Everything → Factory Reset code → OK. |
TCL Fire TV | Home button → Settings → Device & Software → Reset to Factory Defaults → Reset. |
