The TCL TV’s black screen of death is an issue where the screen of your TCL Tv gets black, Blank, or dark. TCL Tv stops responding to any input command with no image display on the Tv screen. 

Sometimes, the screen gets Black or dead, but you can still hear the sound. The black screen issue may be due to poor cable connections, broken or damaged panels, a Blacklight issue, enabled power-saving mode, or Software issues. 

What Are The Reasons For TCL TV Black Screen Of Death?

There are many reasons for the TCL Tv’s Black Screen of Death. Here I will mention the most common reasons. The following are the reasons for TCL TV’s Black Screen of Death.

1. Manufacturing Defect

A manufacturing defect includes a damaged screen, corrupted motherboard, malfunctioning power supply, or blacklight. 

A defective screen or blacklight would not display any image on the screen. The faulty motherboard or power source would not respond to the given command, and the screen would remain Black.

2. An Updated Software 

Smart TVs come with software that needs to be updated regularly. Similarly, TCL TVs also require software updation. If you delay the updation, the Tv may perform slowly, and the Screen will stop displaying anything. 

3. Poor Or Faulty Cable Connection 

Poor cable connection is the most common reason for a Tv’s black screen death. It happens when any cable connection gets loose or breaks—a broken or loose cable connection cause weak signal strength and a Black screen. 

4. Panel Issue 

A TCL Tv’s Black screen death might be due to the damaged panel. Mainly the panel issue creates a horizontal or vertical line on the screen. But sometimes a broken or damaged TCL Tv screen gets black and stops displaying an image. 

During the panel issue, there are two possibilities. First, you can hear the sound but can’t see the picture—second no sound with no image on the screen. 

5. Tv’s Motherboard Malfunctioning

If you see the TCL TV’s Black screen of death, it is possibly due to the malfunctioning of the TCL TV’s motherboard. 

When your TCL Tv motherboard does not process correctly, the TV screen cannot function or display anything. That’s why the Screen looks dark or black without any image due to the corrupted motherboard.

6. The Sleep Time Is On 

Being a TCL Tv user, you often experience the Black screen of death due to the enabled sleep time. 

This is very frequent that we turn on the sleep time and then forget it. Then suddenly, while enjoying streaming on a TCL Tv or any other Tv, the TV Truns OFF. We consider it a technical issue, but it’s not. 

7. Blacklight Issue

A Blacklight on the TCL TVs is designed to control the image on the TCL TV screen. This light makes the image color vivid and vibrant on the screen. 

The Blacklight on the TCL Tv is also responsible for controlling the image or screen brightness. If the backlight of the TCL malfunction, it affects the screen image, and the screen gets black. 

8. Power Saving Mode Is On

If you have enabled the Power Saving mode, it saves electricity or lowers the brightness. 

If the TCL Tv is on and no one is watching for an extended period, the Power saving mode would automatically saves electricity. 

The power saving mode also activates when you watch the TV for a long time. When the Saving mode starts automatically, sometimes it lowers the brightness to such an extent that the screen looks darker. You can also enable the Power Saving mode from the TCL TV settings.
