Smart TV models are getting popular nowadays as they offer a lot of features compared to traditional Tv models. One such Smart TV model that’s popular in the market is the LG TV. This South Korean manufacturer has several Smart TV models available in the market that can connect to the internet allowing you to access your favorite streaming services.
Why does my LG TV screen keep going black?
One of the issues that you might experience with your LG TV is the black screen of death problem. This is characterized by the TV screen showing nothing but a black screen even when pressing the power button or any button on the remote control or TV itself. This can be an annoying issue especially if it occurs randomly and constantly.
Here’s what you need to do to fix the LG TV black screen of death issue.
Solution 1: Power cycle your LG Smart TV
The first thing you will need to do in this case is to power cycle your LG TV. Power cycling is the process of turning off the TV then turning it on again. It refreshes the software of your LG Smart TV and removes any glitches that could be causing this problem.
Power cycle LG Smart TV and router
Unplug your router from the socket.
Unplug your LG Smart TV from the power source.
Wait for 3-5 minutes, and after that plug in your router and let it boot up completely.
Plug in your LG Smart TV and turn it on using the LG remote.
Try checking if the LG TV black screen of death issue still occurs.
Solution 2: Check the all the cables
You need to make sure that the cables connected to your LG TV are tight and secured. This includes the HDMI cables, power cable, and even audio cables.
If you have a faulty HDMI cable that connects your LG TV to a multimedia device then it’s very likely that you will be getting the black screen of death issue. Try using a new HDMI cable and check if this will eliminate your LG TV’s black screen problem.
Sometimes, even after trying multiple HDMI cables you will still get the black screen of death issue. If your TV has another HDMI port then try connecting the HDMI cables to this port as the problem could be caused by the HDMI port you are originally using.
Another thing to consider is a loose power cord. Make sure that the LG TV power cord is connected securely to the power outlet. It’s recommended that you don’t connect the LG TV to a power strip but instead connect it directly to the power outlet.
Solution 3: Check picture mode setting
Another factor that can cause this problem is your LG TV picture mode settings. If your LG Smart TV has incorrect picture settings such as zero brightness and contrast then you will most likely be getting a black screen.
Change picture mode on LG Smart TV
Press the “Home” button on the LG TV remote.
Toggle to Settings and go to All Settings.
Select Picture Settings.
Set Picture mode as Standard.
Decrease the backlight between 10 to 30.
Set brightness up to 50.
Try checking if the LG TV black screen issue still occurs.
Solution 4: Turn off Standby mode
You will get the LG TV black screen if you have set it in standby mode. When in this mode your smart TV backlight will turn off to conserve power.
To turn off this mode go to your LG TV settings menu then select Sleep Timer. Turn off this feature. Your LG TV will not automatically turn off unless you manually do so.
Solution 5; Perform a factory reset on your LG TV
Sometimes this problem can already be caused by a software glitch or bug. In order to fix this you will need to factory reset your LG TV.
LG TV Factory reset
Go to the Settings menu.
Go to All Setting and select General.
Select Reset to Initialize Setting.
Press the OK button to start the resetting process. This reverts the LG TV back to its factory settings.
After the LG TV has reverted back to its factory settings try to check if the black screen issue still occurs.
Solution 6: Contact LG TV for repair
In case the above troubleshooting steps fails to fix the problem then you will need to contact LG for repair.
If this is caused by a hardware issue such as a damaged power supply board or a faulty screen then this needs to be fixed at a service center.
