Why does my TCL TV have no picture but sound?
This problem occurs due to a fault in either the software or hardware. A hardware issue affects the display screen. For example, the LED Lighting of the TV. A defect in the screen is also an example of a hardware issue.

HDMI stands for High Definition Multimedia Interface. It is responsible for transferring both HD audio and video over a cable. It plays an important role in the display of the television.

How to fix TCL TV no picture but sound?
Method 1: Make sure Power cord is firmly plugged
The first step is to make sure that the power cord is firmly plugged into both the TV and the wall outlet.
Sometimes, the power cord can become loose over time, causing the TV to not turn on or function properly.
Also, make sure that your wall outlet is working by plugging in another device to the outlet. If the other device doesn’t work, then the problem may be with the outlet and not the TV.
If the power cord and outlet are both working, but the TV still doesn’t function properly, it could be a problem with the TV’s internal power supply.
Method 2: Restart your television
This method will help your TCL TV start fresh and prevent the bugs affecting your television set. It will restart both your hardware and software.
