[Fixed] TCL TV Screen Goes Black But Sound Still Works

There are many reasons why your TCL Tv screen goes black with sound, but most probably, it is due to the damaged cable connection and any hardware issue of your TCL.

Check the TV cables first whenever you feel any issues with your TCL TV. These cables often get damaged or slightly disconnected from the main source or Tv. 

These input cables are responsible for displaying any content on your TV. Look at these input cables and repair or replace them if damaged.

2. Temporary TV Malfunctioning

If your Tv is getting old and faces different issues frequently, it may need to be fixed. This may be why this is the issue with your TV, not the screen. You can overcome this issue by restarting the Tv.

3. Software Os Issue

When our TV requires an update, it alerts us for updation repeatedly. Mostly we set the reminder to “remind me later” and forget to update again. 

Then often, the TV doesn’t work accurately due to outdated updates, and the screen gets black.

TCL Tv blacklight consists of many LED strips. Even a single faulty strip can damage the complete blacklight. 

If your TCL Tv blacklight stops working, it can stop displaying images on the Tv. Now the screen may be black due to any hardware issue. Then first check the hardware.

Turn on your mobile flashlight or hold any other flashlight. Take the light near the screen. Check it on the remote if you see even a light image on the screen. Test the screen by decreasing or increasing the TV volume.

If your TCL Tv remote can control it, it proves that the Tv hardware, like T-CON and Motherboard, works well. This indicates some issues with the blacklight. 

In this case, you need to replace the backlights of your TCL Tv. This is a difficult task. I suggest you contact TCL customer support or any other technical professional.

6. Power Cycle Your Tcl Tv

There are two methods of power cycling; one is the same as a reboot or reset. To try that method, follow the same steps you tried for the reboot. Now let me teach you the other method. 

  • Turn your TV Off and unplug it from the main source.
  • Find the reset button on the bottom of the Tv. 
  • Use a toothpick or paperclip to press the reset button.
  • Hold the Reset button for around 30 seconds.
  • Wait for a few seconds and Turn on the Tv back.

Sometimes you may need to power cycle your Remote. Follow the steps below to power cycle the TCL Tv remote.

  • Remove the back of the Remote.
  • Take off the batteries.
  • Wait for 2-3 minutes.
  • Lastly, Place the batteries back carefully.

  • Press the Home button on your TCL TV remote.
