Is your LG TV giving sound but no picture? When you turn the TV on, the screen goes black. So, the audio is delivered but the video vanishes. This can happen with any TV including LG. There are different reasons for this issue. For example, a problem in the remote control, power outlet, TV’s firmware, connection cable, or backlight. You can try some very useful tips before consulting a technician.
This article will provide you all the working solutions. Let us explore the reasons for LG TV’s black screen with sound and apply the solutions.
1. Check the Remote Control
A faulty remote control may be the reason your TV screen is black. Turn the TV on/off using the power button on your LG TV. If it works then your remote has stopped working. You need to fix it. Just change the batteries of your remote. If it does not work then you need to replace the remote.
2. Change the Wall Power Outlet
Another reason for the black TV screen is a faulty power outlet. Maybe it is not supplying full voltage that’s why your TV is giving sound but no picture. So, plug out your LG TV. After a few minutes, plug it in the same power outlet. Another solution is to plug in your LG TV to a different wall power outlet. This trick can help you in solving your problem.
3. Check the Connection Cables
Usually, people do not bother to check the connection cables. A damaged connection cable is one of the major causes of a black TV screen. Check the connection cables like HDMI. Maybe the cable is faulty, not inserted in the relevant port, or not plugged in properly.
Plug out the HDMI or other audio/video connection cables. Wait for a few minutes and again plug in all the cables properly in your LG TV’s connectivity ports.
A loosely connected HDMI cable causes a black screen. You should also try to insert the HDMI cable in another connection port on your LG TV. Another trick is to use your HDMI cable with a different TV or device.
In this way, you can find whether the problem persists in the cable or in your LG TV. If it does not work then you should try a different HDMI cable for your LG TV. You need to replace your older cable if the new one solves the issue of the black LG TV screen.
4. Change the Settings on Your LG TV
If your LG TV is giving sound but no picture, it may be due to the wrong settings. One possibility is that the backlight is expired. While the other reason is the wrong picture mode. So, you need to check both these settings.
You can check the backlight issue by projecting the torchlight on your TV screen in the dark. If the screen is displaying images in the background then there is an issue in the backlight. It needs replacement. However, you can fix this issue to some extent at home. Follow the instructions given below;
- On your LG TV’s menu, open ‘All Settings’.
- Click on the ‘Picture’ settings and navigate to the ‘Picture Mode’ settings.
- Select the ‘Standard’ picture mode.
- Next, reduce the backlight brightness. Select the minimum backlight value, from 10-30.
- Change brightness settings and set it to 50.
These settings lower the risk of backlight overheating. So, your LG TV screen will not turn black.
5. Reset Your LG TV
Another reason for the black TV screen with sound is some problem in TV’s firmware. First of all, look at the power indicator light. If it is on, your LG TV has a software issue.
The software creates problems when it has been affected by bugs or errors. Software issues may also arise when you do not shut down the TV properly. Moreover, the older software version can also affect the picture display. The most effective method to fix this issue is power cycling your LG TV.
Follow the instructions given below;
- Turn your LG TV off and disconnect the power supply.
- Leave it turned off at least for 10-15 minutes.
- Next, connect your LG TV to the power outlet and turn it on.
- Hold and press the power button at least for 10-15 seconds.
Another method to power cycle your LG TV is;
- Press and hold the ‘Volume Down’ and ‘Power’ buttons simultaneously.
- Unplug your LG TV from the power outlet.
- Wait a few minutes and turn the power supply on.
You can try either of these solutions or both. They will fix the issue of the black LG TV screen with sound. However, if it does not work, move on to the next solution.

7. Update the Software
Usually, when an LG TV’s screen goes black but with sound, it keeps on performing other functions. For example, the LG logo appears on the screen when you turn the TV on. Further, the settings, apps, and audio also work. But, you get no picture display. If your LG TV is in a similar mode, you should check for software updates.

8. Hardware Issues
If none of the above-suggested solutions works, your LG TV has got some hardware damage. Contact with water or moisture can damage the hardware. Another reason is that your TV has hit the ground or something else.
There may be a fault in the motherboard or power supply board. Your LG TV has integrated multiple power supply boards. A fault to any of them can create the black screen issue.
In this case, you should consult a TV mechanic. He can sort out the real hardware problem. The other option is to contact the manufacture. If your TV is under warranty then you must consult the LG customer’s support.
