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.
