Why is My LG TV Screen Black?
There are several reasons your LG TV screen could be black. Here are the common ones you need to know to avoid bad experiences when watching or turning your television on:
- Remote not working: A black screen could be an indicator that your LG TV has been turned off. However, if it’s producing sound, that’s not the case.
- In either case, the first thing you should do is to establish whether the remote is working. To do this, power the television on using its power button instead of the remote. If that solves the issue, but the remote still doesn’t work, it has a problem.
- Issues with the TV’s firmware: If there are no remote issues, check whether the power indicator light is on. If so, software issues could be the underlying cause of the problem. If you don’t follow the recommended way to shut off the TV, the TV software may experience technical difficulties. The inability to install new updates in time is another possible reason. In some cases, software issues can emerge without any known reason, but you can solve them.
- Failure in the TV’s power supply board: A wide variety of power supply issues can hinder the normal functioning of the screen. Failure in the power supply board is a major problem. The TV might have several power supply boards. So, a failure in one of them could interfere with the ability of the screen to function normally.
- Connectivity issues: A faulty HDMI cable can cause lots of issues with your TV display. It could have been damaged or malfunctioned due to tear and wear. Alternatively, the HDMI cable and power cables could be loose.
- Backlight issues: If your LG TV is using an LCD screen, you should consider whether the backlight is functional or not. Use a flashlight to try to see if images appear in the background. If you are experiencing backlight issues, you’ll see the pictures if you do this in a dark room.
Why Does My LG TV have Sound But No Picture?
- Your LG TV can have sound but no picture due to software-related complications. Depending on the nature of the problem, it can cause the TV to have sound but no picture, picture but no sound, or none.
- Since HDMI cables deal with display, you are less likely to get quality images if damaged or malfunctioned. The same problem can occur if the cable is loose.
- Backlight issues are another major cause of this issue. This can be a concern if your LG TV uses an LCD (liquid crystal display). Please remember that the advanced OLED (organic light-emitting diode) TV doesn’t use a backlight to transmit light.
- If the LG TV’s input source is damaged or not turned off, the screen can turn black too. The same can also happen if the source is not connected to power.

- Plug the TV into different outlets
- If it works, call a competent electrical to address the issue or use the functioning wall outlet.
4. Check all the Cables Plugged into Your TV

Change the faulty ones even if they appear to be in the right physical state. They could be interfering with the current flow.
5. Check the Backlight and Power Supply Board
Check the backlight if you are using an LCD screen since it uses the backlight to enable you to see images.
If it stops working, the screen will appear black, but you can still see images if you shine a flashlight on the screen when the lights in the room are turned off.
