How to Fix TCL TV Black Screen

Why does my TCL TV have a black screen?

The main reason your TCL TV is showing a black screen is because of a faulty HDMI connection or corrupt firmware.


Have you ever observed that while you’re watching a movie on TV, the screen goes black, and you can only hear the sound but not see the picture? This is a typical issue among TCL TV owners, and it has to do with the design of the TV. There are several easy things you may attempt that may resolve your issue.

One of the key advantages of the TCL TV is that it is a low-cost TV with large screen sizes, which means that it lacks some advanced capabilities that other TVs offer. One example of missing functionality is that all TCL TVs have a black screen problem.


To repair your black TCL TV, switch it off and on again. It’s also worth attempting a fresh HDMI cable to ensure that the port hasn’t been physically damaged — or if there’s a problem with the power supply.

  • There are several reasons why your TCL TV screen may not display video even though you can hear audio and your device is still operational
  • When your TCL TV goes dark, it’s typically not the end of the world. It’s most likely a problem with the HDMI connection that links the TV to whichever device is supplying the display


The simplest method to troubleshoot this sort of issue is to determine which piece of equipment — TV or source device — is to blame.

A malfunctioning backlight is one of the most common causes of a blank TCL TV. Many current televisions employ this technology to produce images, but when it fails, you’re left with a black screen that only serves to annoy you.


Possible Causes:

  • Power cycle issue
  • Faulty connections
  • Firmware issue


Power Cycle Issue

In any recovery method for TCL TV black screen issues, the first step is to reset the TV by removing it from any source of power and spending 30 to 90 seconds before connecting it back in. In this scenario, we’re going to try a power cycle reset.

The process of disconnecting or withdrawing the power supply from electronic equipment and keeping them off for up to a moment before putting them back in is known as power cycling.

TVs, like any other electronic item, can have system issues caused by an erroneous adjustment in the settings. A simple restart can remedy these issues, and you should utilize it whenever your TV’s screen fails.


Faulty Connections

When working with a broken television, the first thing you should do is ensure that everything is connected.

Sit down in front of your TV and double-check that all of your cables are correctly plugged in and operating properly.

If any couplings were loose, or if the cables were broken, you must change your HDMI cords as quickly as possible.

Check to ensure that all of your cords are firmly in place if you start experiencing black displays at random.


Firmware Issue

Software upgrades are critical on TVs, and TCL’s TVs feature an excellent means for doing so. Many TV manufacturers now manufacture their smart TVs, which implies that upgrades come directly from the company rather than via channels such as Roku or Chromecast.

The TCL TV has its built-in store, so you can discover updates by navigating to the settings menu and scrolling down to the applications area.

Firmware upgrades, like practically any other Android device, are rather straightforward to install; it’s a quick procedure that will only take a few minutes of your time.

The software on your television is always being upgraded. TV companies now distribute software upgrades regularly, much like they do new applications.

How do I fix a TCL TV black screen?

To fix a TCL TV black screen, switch it off and on again. It’s also worth attempting a fresh HDMI cable to ensure that the port hasn’t been physically damaged or if there’s a problem with the power supply.


Possible Causes:

  • Power cycle issue

Power Cycle Issue

Check that the power is turned off. Unplug the TV from the wall and set it aside for 1-2 minutes. Reconnect the TV. Typically, you will see the lights turn on and then be able to restart your television.

The remote serves as the machine’s signal repeater. It, like any other signal repeater, can become jammed at times, especially if you use numerous remotes nearby.

To resolve this, disconnect the remote from its charging cradle, wait a minute or two, and then plug it back in. One by one, the lights on the machine should come back to life.


Faulty Connections

If you’re having the opposite problem (for example, no signal at all), try pushing the TV’s Input button many times until you discover the port that works.

If your HDMI cable is growing old (they normally last approximately 5-6 years), I’d recommend replacing it.

Before investing in further equipment, consider replacing the HDMI cable that came with your TV and seeing if that fixes your problem.

If you’re still having problems, or if you have an older TV without an HDMI connection, a Belkin Ultra HD HDMI connection can let you run your cable through the walls to a new spot.


Firmware Issue

These updates contain bug fixes and enhancements to your operating system, so you should update them regularly to guarantee your TV performs optimally.

Look for and install any software updates on your TCL Android TV regularly to keep it up to date.


Here’s how it’s done:

  • Navigate to the Settings menu by pressing the Home button on your remote
  • Select More Settings from the Settings menu
  • Select About from the Device Preferences menu. Select System Update now
  • Select Network Update from the window that displays
  • Your television will now look for any available software upgrades
