Screen Television Tv Monitor Black

When the TV screen goes black, but the sound still works, it implies the TV is working fine. However, an interruption in the cables is preventing the device from displaying the picture on the screen. 

Outdated TV firmware and incorrect input sources can also trigger this problem. The TV screen might appear black due to a glitch in software or hardware.

Whatever the reason behind the TV’s black screen error is, it can be fixed easily. All you need to do is detect the source of the problem. After that, implement the right solution to restore the TV’s display connection. 

However, you might need an expert’s help if the error occurred due to a faulty or misaligned TV screen.

Now, let’s find out the possible causes and solutions for the TV’s black screen issue.

Why does the TV Screen goes black but Sound Still Works?

There are multiple reasons why the TV screen suddenly turns black, but the sound works. A malfunctioned TV panel can generate this technical issue. When this happens, you must consider replacing the screen. Otherwise, resolving this critical issue might be challenging.

Here are the other reasons why the TV screen goes black but the sound still works:

Power Failure on Supply Board 

The TV screen might go black due to a power failure on the supply board. Depending on the TV you use, there might be more than one supply board with a T-Con board. 

If the supply board stops functioning, the TV will fail to display any image. However, you can still hear background sound if the TV is on.

Backlight Problems

An LCD TV uses a backlight to light up the images displayed on the screen. If the backlight experiences any technical glitches, the screen won’t illuminate, and it will turn black. TV users might repair the faulty backlight strips to eliminate this hardware problem.

Faulty or Loose Wire Connections

Sometimes, the TV displays a black screen for loose or faulty wire connections. Thus, check if the cables and wires of the TV are fastened tightly. Besides, you must look for worn-out TV cables and wires. If you notice a frayed HDMI or power cable, replace it immediately.

Power Saver Mode and Sleep Timer Mode

The latest TVs’ feature a power-saving mode that turns off the screen when not in use. Users might hear the background sound in such instances, even when the TV screen is black. You can also experience this issue when the TV’s sleep timer mode is on.

5 Easy Fixes for TV Screen Goes Black but Sound Still Works

By now, you might have acknowledged what causes the black screen issue on the TV. Try to restart the TV using the remote control and check if that solves the problem. 

If the black screen error persists, try out these solutions to fix the complicated TV error:

1. Check and Change the TV Source

There is a high possibility that the source or channel that you are currently watching is causing an interruption. This is why the TV screen appears black. Thus, change the TV source to overcome this technical problem. 

Access another channel or source using the TV remote. If the black screen issue persists on different channels and sources, there is something with the TV settings. 

2. Disable the Power Saving or Energy Saving Mode

The high-end TVs come with a power-saving or energy-saving mode. It helps the users to conserve the TV’s excess energy consumption by turning off the screen. 

However, this feature can often interfere with the TV’s functions. As a result, you will notice no image on the screen. Thus, disable this advanced feature to avoid the black screen error.

Press the remote control’s “Home” button to access the TV’s home screen. Navigate to “Settings” and head towards “General”. Select “Eco Solution” using the “Up” and “Down” keys and choose “Power Saving Mode”. 

Toggle off this option and restart the TV afterwards. You can now stream your favourite channels without experiencing any glitches.

3. Turn off the Sleep Timer Mode

Does the TV screen go black after enabling the Sleep Timer mode? Consider disabling this feature to overcome the problem. Press the TV’s “Home” button and choose “Settings” using the “Up” and “Down” keys. 

Go to “System” and navigate to “Time” to turn off the Sleep Timer mode. Restart the LED or LCD TV after disabling this feature. Choose the correct input source and access any channel to check if the error is solved.

4. Update the TV Firmware

An out-of-date firmware can restrict the TV from displaying any picture, but the sound will work. Therefore, updating the TV firmware can help you to fix this problem. 

The old TV models update the firmware automatically. However, if you use an advanced TV, there are two ways by which you can update the firmware. 

How to Update the TV’s Firmware via the Internet?

Connect the TV to the internet and navigate to “Settings” via the remote. Choose “Support” and opt for “Software Update”. Check if there is any update available for the LED or LCD TV. 

If yes, tap on “Update Now”, and new updates will be downloaded and installed on the TV. Restart the TV once the update is complete, and the black screen won’t appear further.

How to Update the TV’s Firmware via a USB Flash Drive?

TV users can also update the software using a compatible USB flash drive. However, there is a risk of hardware damage in this updating process. Don’t press any buttons when installing the new updates. Otherwise, the TV set might become unresponsive and beyond repair. 

Connect the USB flash drive to the TV’s USB port and ensure it has at least sufficient storage. Access the manufacturer’s support website. Go to the search bar and enter the correct TV model name and choose “Search”. 

Head towards “Download” and follow the on-screen instructions to initiate the update. Reboot the TV when the update is complete and ensure the power cables are connected securely. You can now stream online media content without noticing a black screen.

Lastly, Restore the TV’s Default Factory Settings ….

TV users can experience the black screen error due to misconfiguration. If you fail to understand which incorrect TV setting is causing this problem, reset the device. Access the TV’s settings using the remote control. Go to “General” and navigate to “Reset”. 

Select “Factory Reset” and enter the PIN when prompted. Most advanced TVs have “0000” as the default PIN. However, it may vary from one TV model to another. The TV will restart automatically once it restores the previous settings. Access any TV channel and enjoy your favourite movies without further inconvenience.
