Samsung TV Has Sound But No Picture

Showing visuals and producing sound is perhaps the primary aspect of a TV. However, electronics like TVs may undergo some issue that prevents them from functioning properly. One of the common issues that occur is your TV producing sound but not being able to produce any visuals, rather hosting only a black screen.

Samsung TV that has a sound but is not able to produce any visuals may be due to connectivity, internal circuit boards, backlight, input port problems, or crashed software. To resolve these issues, you’ll need to replace the faulty hardware, such as the T-CON board or the backlight, and update the TV’s software.

If you’re someone who’s struggling with the issue of no visuals on your Samsung TV, don’t worry as this problem can frequently happen to anyone. Keep reading as I address the factors that may potentially cause this problem.

To address the black screen problem you are facing with your Samsung TV, you need to consider these five factors. Either of these five may be why your TV isn’t showing any visuals.

Factors And Their Reasons

The following table aims to help you know the possible factors that cause your Samsung TV to have sound but no display.

Factor

Reason

Connectivity

Fault in the cables such as HDMI or power cable.

Internal Circuit Board

An issue in the internal circuits, such as the T–CON board.

Backlight

The backlight is not working correctly or is completely off.

Input

Fault in the input ports.

Software

The software may have crashed.

Reason 1: How To Resolve The Connectivity Issue?

The connectivity issue occurs due to lousy cable connections on your TV. Resolving this issue can result in the restoration of the display.

Verify that all of the cable connections on your Samsung TV are secure and in good working order. Make sure that your streaming devices, such as Apple TV, Roku, and Chromecast, are securely connected to your smart TV’s HDMI port.

Other than that, you can also replace any damaged power or HDMI cables immediately to see if the Samsung TV black screen issue has been resolved.

Reason 2: How To Resolve The Internal Circuit Board Issue?

Images on your Samsung TV are produced by the T-CON board, commonly known as the logic board or control board. There is a good possibility that the T-CON board is broken if the display is blank, but the audio is functional.

Below are the steps you need to follow to resolve the internal circuit board issue.

Step 1: Find and purchase a T-CON that is compatible with the model number of your TV.

Step 2: Take off the back panel of your Samsung TV.

Step 3: Unplug the ribbon wire and swap the old T-CON with the new one.

However, if you’re willing to fix it by yourself, you should have some experience in dealing with technical things, as this can be a delicate task to perform. Having no such knowledge can result in potentially damaging other components.

Reason 3: How To Resolve The Backlight Issue?

If none of the remedies have worked to this point, it is possible that the backlight of your Samsung TV is broken. If you have an LCD TV, the problem is probably with your CFL lights. On the flip side, as far as LED TVs are concerned, the LED lights might be damaged.

Below are the steps you need to follow to resolve the backlight issue.

Step 1: Find and purchase a backlight according to the model of your Samsung TV.

Step 2: Open the back panel of your TV and remove the ribbon cables attached to the old backlight panel.

Step 3: Install the new backlight panel and connect the ribbon cables firmly.

You can replace the backlight yourself if you have some experience in handling electrical things. Otherwise, you may require an experienced technician to do this task for you.

Reason 4: How To Resolve The Input Issue?

Faulty input ports can also play a role in your TV’s black screen. Ports such as HDMI can get damaged as, most of the time, they are not easily accessible. Trying to connect the HDMI cable in the wrong position and smashing it in the port often cause damage to the input port.

Here’s how you can solve the input issue:

Step 1: Remove the back panel of your TV.

Step 2: Replace the defective port with the new port by desoldering the old one and soldering the new one.

If you don’t have any experience in repairing electrical components, I would advise you to not attempt this resolution and instead seek help from a professional.

Reason 5: How To Resolve The Software Issue?

The smart Samsung TVs have preloaded software, which can crash over time. They may either completely black out your screen along with no sound or just play the sound without any display. To resolve this issue, follow the steps below.

Step 1: If you have a remote, perform a soft reset by pushing and holding the power button on your TV remote until your TV turns itself off and back on.

Step 2: If you don’t have a remote, disconnect your TV from the outlet, wait for 30 seconds and then plug it back in.

If the five factors mentioned above don’t work for you, you may try some other ways that have been trusted to help fix a Samsung TV’s display:

Test Various External Devices

External devices can cause the screen of your Samsung TV to go black as well. One of the causes is a faulty HDMI cable used to connect an external device. So, the external gadget you’re utilizing is the last item to rule out. Use a new source port, or try connecting a different device. If the issue is still not resolved, try using a new cable.

Replacing the Damaged Screen

The broken TV screen is yet another potential explanation for why your TV isn’t showing any images, yet the sound is fine. Extreme temperature and electrical surges are only two of the numerous factors that might harm a TV screen. The good news is that a trustworthy TV repair professional can replace the broken TV screen quickly and easily.

Power Cycle

It would be best if you tried the traditional, old-fashioned power cycle initially. Unplug your Samsung TV from the wall and turn it off. Please wait a minute to allow any residual charge in the capacitors or memory to dissipate. Reconnect the TV’s power and turn it back on after that.
