Cause of the LG TV Black Screen Issue with No Picture but with Audio Working

There are a few possible causes for your LG TV to experience a black screen with sound or audio still working. Below are the most common causes:
- The television is on an input that does not have a signal.
- The volume on the television is turned all the way down.
- The television is muted.
- The power saving mode or eco mode on the television is enabled.
Tips to Troubleshoot and Fix Black Screen Issue with No Picture but with Sound on LG TV
First, check to see if the issue is with the input by swapping to a different input or source. If the problem persists, try power cycling the TV by unplugging it for 30 seconds and then plugging it back in. If the black screen persists, try resetting the TV to factory settings.
This can be done by navigating to the Settings menu and selecting the Reset option. Finally, if none of these solutions work, you may need to contact LG customer support for further assistance.
What to do when your LG TV turns on, but the screen is black, and there is no sound?
The first thing to do is check all of the connections. Make sure that the HDMI cable is firmly connected to both the TV and the external device. Next, power off both the TV and the external device and then power them back on again.
Then, try hard-resetting the TV. To do this, unplug the TV from its power source and then plug it back in. Once the TV powers on, press and hold the reset button for 30 seconds. This will restore the TV to its factory settings.
If you are still experiencing a black screen or no sound, contact LG customer service for assistance.
How to Prevent the LG TV Black Screen or No Picture Issue from Happening
- Check that the power cord is plugged in correctly and that the outlet has power.
- If you have another TV or monitor, connect your LG TV to it using an HDMI cable to see if there is a picture on the other device. This will help you determine if the problem is with the TV or with something else, such as the cable box or HDMI input.
- Contact LG customer support for further assistance.
