Tcl Tv Screen Goes Black But Sound Still Works [Fixed]

For many fans of television, it is a scenario that causes a great deal of anxiety. 

You get ready or sit down to enjoy your show, and you have your favorite snacks with you.

Suddenly, the TCL TV screen blackens while the sound remains unaffected. 

This annoying situation happens all because we are trying to unwind and take a breather.

However, there is no cause for concern! This page is meant to assist people who are wondering why their TCL TV has a black screen and offer practical solutions to the problem.

Identifying and Defining the Problem: What Causes This?

Internal Hardware Glitches

A black TCL television screen with sound is unfortunately a common occurrence. This may be caused by hardware malfunctions. 

A television is essentially an electronic device with different components that perform different functions and have to work together. 

So a small temporary defect in the circuitry may result in a black screen.

Software Issues

It is also possible that software bugs can affect how your TCL TV functions. 

This includes firmware upgrades, trouble with one of the supported streaming services, or errors in the OS that do not let the video signal work properly where the audio does.

Problems with HDMI Connection

Another cause worth mentioning is the defective HDMI connection. A loose, damaged, or broken port HDMI cable can block the video signal, which in most cases results in a blank screen. 

This is particularly true if you have several devices such as a gaming console or streaming box connected to the television.

Problems with powering the set

Another cause of the black screen could be power supply failure. 

The TV may try to display while there is no constant power supply or a range of voltage fluctuations exist, further complicating matters.

Over Heating

It’s possible that the internal parts of your TCL TV may stop working for a while but only due to overheating.

 It is possible for the TV to overheat due to a poor location with little airflow or if it has been left on for a long period, causing a black screen.

Panel Issues

Finally, there could be problems with the screen panel of the TV or itself. 

This may be a missing panel, a defect, or damage that completely disables the display leading to a black screen.

Troubleshooting Steps to Fix the Black Screen Issue

Having diagnosed the potential causes, it’s time to get your hands汙up and dirty while following some steps to troubleshoot and fix the issue of the screen on your TCL TV turning black while the sound is still playing.

Step 1: Turn Your TCL TV Off And On Again

As often happens with electronics, the simplest solution is to turn the device off and on again. The process is as follows:

Switch the TV off: 

You can do this using the remote control or the television set’s power button.

Remove the power supply connector: 

Disconnect the TV from the mains and wait for about a minute. This is to ensure that any power left in the television dissipates.

Replace the plug: 

Then connect the power cord back to the socket and turn on the TV.

At times, turning off a device and subsequently turning it back on again often resolves all minor difficulties and the image is visible once more.

Step 2: Check HDMI Connections

If the restart doesn’t work, the next step is to check all your HDMI connections:

Inspect the HDMI Cable: 

Ensure that the HDMI cable is securely connected to both the TV and the external device (like a cable box or gaming console). 

If you notice any damage to the cable, consider replacing it.

Try a Different HDMI Port: 

Unplug the HDMI cable from the current port and try plugging it into a different port on your TCL TV. 

Sometimes, specific ports can malfunction.

Test with Another Device: 

Connect a different device (like a Blu-ray player or another console) to see if the issue persists. This can help determine if the problem lies with the TV or the original device.

Step 3: Execute Factory Reset

If the above method does not work, then the last option would be to execute factory settings. 

It’s important to understand that this option will wipe out all the settings and configurations, so be careful:

Navigate to Your TCL TV: 

By making use of the remote, go to the settings option on your TCL TV.

Under System: 

Locate the option that is labeled as System as you scroll down.

Select the option of advanced system settings: 

Here, you will find the option of missing settings and will perform a factory reset.

After that, you have to Choose Reset: 

Next, click on it and confirm the factory reset from the given prompts.

Setting the TV back should be followed after a complete factory reset but it quite often rectifies stubborn issues concerning software on the television set.

Step 4: Do Not Use the TV when hot

If your TV gets hot, it will lead to certain performance problems such as a black screen. To make sure that your TV can move the heat around:

Examine areas around the television: 

Ensure the television is in a dry place with no obstructions. Do not place it in a closet or too close to anything hot.

Hurry up: 

If you got the impression that your TV set was overheated, then it should be turned off with a plan not to use it for 30 minutes adjusting any settings before switching it on again.

Step 5: Update Software/Firmware

One can also prevent this issue from occurring by ensuring that your TV’s software is always updated. 

Here are the steps to be followed in updating the TV’s software:

Select About: 

Choose the About option to search for software updates.

Go to settings: 

Using your remote, go to the settings section.

Choose System: 

Locate the System section.

Select System Update: 

Click on check for updates.

Install Updates: 

Click on the update button if new updates are available.

Step 6: Contact Customer Support

All in all, if all the fixes above fail to fix the problem, it may be wise to get in touch with TCL customer support or service for assistance. 

When calling them, state your area of residence so that they can provide assistance catered to your TV model and the symptoms. 

They may also offer repair or replacement for your television if it is still under warranty.

Tales from My Life: 

The Case of the Black Screen

As a dedicated TV aficionado, I vividly recall one particular evening when my TCL TV screen decided to go black in the middle of an episode of my favorite series. 

There was still sound, which raised the tension as I sat there in that moment of helplessness, trying to comprehend why it was all happening.

I had given up on looking for the source of the problem and asked myself whether purchasing a new television was the only decent solution left. Thankfully, I calmed down and focused on systematically working through the troubleshooting manual. These observations became evident after I quickly rebooted the computer and then looked at the HDMI connections. 

The HDMI cable had been disconnected during my last marathon session.

As soon as I resumed power, I felt relieved as the screen came on and flickered. 

That evening was somehow useful, as I understood the need for patience and a systematic approach to technology troubleshooting in the future.
