If your TCL Tv screen gets black and no image appears on the screen, your TCL Tv screen has display issues. If not, even a small image is displayed on the screen. There might be two possibilities that should be discussed separately. 

One is the TCL TV screen goes black, but the sound still works, and the other is no image with no sound. Here I am talking about the second one. Your TCL Tv will stop displaying any image without sound. 

Possible Reasons

  • Your TCL Tv is incorrectly connected to the main power source, or the Cables used for connection are damaged.
  • Speakers have muted accidentally, or the volume is set too low.
  • There might be some issue with internal hardware like the motherboard or blacklight.
  • The TCL Tv is malfunctioning.


Connect your TCL Tv to a different power source or replace the cables. Go to the TCL TV’s settings and ensure the Volume setting. If the volume is low, increase it, or if the volume is muted unintentionally, unmute the volume. 

Check the TV’s Hardware to see if it is functioning well. In case of any hardware issue, analyze the problem. If you can fix the issue, fix it; otherwise, the best option is to contact TCL Tv customer support

2. Flickering Or Flashing Screen of your TCL Roku TV

Flickering and Flashing screens can cause health issues. Flashing affects your eyesight and causes other eye issues if you watch the screen for a long time. Therefore you need to solve this issue quickly to avoid any further disturbance.

Possible Reasons

  • Most often, the reason behind this issue is a loose Cable connection or poor Signal connection, which leads to a Flashing screen.
  • A wrong setting like refresh or incorrect picture settings.
  • Unstable power supply.


Repair all the damaged Cables or replace them if needed. Cables responsible for Image display on screen are most likely to be damaged. Therefore look for those cables first. Then Replace the cable to fix the issue. Keep changing cables regularly after a particular time. 

Flickering and Flashing can be due to poor signal, so remove all the obstructions and place the wifi device near the TV. Go to the settings and check if there is any incorrect setting. Set it accurately. The power supply may not be working if this is the case change the power board.

Suppose your TCL Tv is showing Horizontal or vertical lines on the screen. This is due to the following reasons.

Possible Reasons

4. Ghost images or burn-in on the screen

Ghost image refers to a left image from the previous screen display. Simply, it reflects the previous display in the next picture. A burn-in screen appears due to the dimming and discoloring of a group of screen pixels. Both issues have the same reasons and solutions.

Possible Reasons 

  • Displaying Static images for an extended period
  • Too high Brightness 
  • Turning on the TV for a long time without any break
  • Keep watching the same display or channel 
  • Low-quality LCD or LED panel


The most helpful solution is to display the same image briefly. Go to the settings and lower the Brightness because it causes overheating. 

Avoid sticking on the same channel for a long time. Note when you Turn on the TV, give it a break after some time and then turn it on again. 

Some TCL Tvs come with low-quality panels. Replace your TCL Tv’s old panel with a high-quality panel.
