Why Does My LG TV Screen Go Black Randomly?

LG TVs have experienced some issues in the past, and this includes the screen going black randomly. The most common cause of the black screen is a loose connection between the power cord and the device or your LG TV has a bad connection to the internet or your cable.
However, this is not always the case, and in this guide, we provide all possible reasons and the best way to fix it.

Why Does LG TV Screen Go Black Randomly? [FIXED]
The LG TV screen goes black randomly, and it is not just a problem with the TV. There could be many reasons for this issue, but most of them are related to the power supply.
This is a common problem that LG TV customers are facing. The reason for this issue is that LG TVs are designed to be energy efficient, and they turn off their screens when they detect no signal.
They do this to save power when there’s no signal or low signal. The TV will go black for a few seconds and then turn back on.
The solution for this issue is to check your LG TV screen connections and make sure they are tight and secure. You can also use an HDMI splitter to prevent signal loss from your signal source if you do not have enough input on your LG TV screen.
If you are not sure what is causing your LG TV screen to randomly go black, consider these possible issues below.
Damaged Or Loose Connections
Sometimes, the simple reason for a black screen on your TV is something as simple as a loose cable.
It is not always necessary to call in a repairman if you know how to fix the issue yourself.
The most common cause of a black screen is an issue with the HDMI cable connecting the TV and the source device.
If you’re using an HDMI connection, make sure that your cables are in good condition and that they’re securely connected to both devices.
Depending on your TV setup, you should check for any loose cables behind the TV. You can also test the cables with a different TV to ensure they are working properly.
Power Source Problems
One of the most common problems with LG TVs is that they randomly turn off during use and show a black screen. This issue can often be fixed by replacing the power source with a new one.
This can be determined through general troubleshooting like a TV reboot. You should also avoid overloaded power strips when possible with your LG TV.
We recommend always plugging your TV directly into the wall.
If the problem persists, try the power source cable on another TV to see if it works. This will help you narrow down the problem.
The internal hardware problem on an LG TV is the most difficult to identify as a consumer.
This is because there are many parts inside of the TV that consumers can’t see and can’t access without opening up the TV. This makes it hard for consumers to identify which part has a problem.
We would recommend contacting a technician or LG technical support right away if you believe the issue on your TV is related to the internal hardware failing.
Software Or Firmware Issues
Depending on your model and year of the TV, it is a strong possibility the software or firmware is outdated. Many times, a quick update solves the black stream issue for customers.
You can head into the settings area on your TV and find the firmware updates section. If there are any available updates, this is where they would be.
If you see one available, simply click the update button to initiate the download. Depending on the update, it can take anywhere from a few seconds to a few minutes.
You will also see the TV turn off and back on. The reset is designed to force the new firmware to update without any action required.
Most LG TVs will include an array of different input options like HDMI with more than one for each too. It can be confusing at times for the owners of these TVs.
This leads to the problem where you have your TV connected through the HDMI 1 port, but you are looking at the black screen on HDMI 2.
Be sure to double-check the inputs and make sure you have the right one selected when determining what is causing your random black screen.
Power Save Mode
Another useful setting that could go wrong is the power-saver mode. This is meant to shut your TV off after inactivity so it doesn’t stay on all day.
When this is selected, it could cause your TV to go into sleep mode and give you a random black screen. Check your power mode settings as a precaution.
How To Fix Black Screen On LG TV
When watching a TV show or movie, the black screen can be an annoying experience. This happens when the TV is not receiving enough power to run the display properly.
This can be a frustrating problem as it means that you won’t be able to watch content, and you will have to do some troubleshooting to fix it.
Below are some quick and easy steps that will normally fix the random black screen on your LG TV.
Unplug Your TV
In many cases, you can get rid of the random black screen on your LG TV by tinkering with the power source. Start by unplugging your TV from the outlet and allowing it to sit idle for at least five minutes.
We recommend starting here to try and diagnose the problem because it will instantly restore your screen if it is nothing serious.
However, if you continue to see the black screen, it could mean something more severe is wrong with your TV.
Test The Remote
It is not uncommon for people to experience problems with their TVs, remotes, or other electronic devices.
Sometimes these malfunctions can be caused by a simple software glitch, but most of the time, they are caused by hardware issues.
In this case, you should first try turning on your TV manually without the remote and then do some troubleshooting to determine if it is indeed the remote that is malfunctioning.
If you still cannot turn on your TV manually, you can eliminate the remote as a potential problem to address.
Replace TV Power Cables
If you were able to identify any faulty plugs causing your black screen, getting replacements is quite simple. They can be found online cheap, or you could directly contact LG for replacements.
Try A Different Input
You can also try different inputs on their television to see if one of them is defective. This process will help you troubleshoot the problem and find out which connection is not working properly.
A defective input connection can make it difficult to get your device to run. When trying to access the channel, the screen remains black because the connection cannot detect your TV.
Factory reset is a process that restores the device back to the default factory settings. This includes restoring the settings to their original state and deleting all personal data.
If you are having issues with your LG TV, it is possible that the issue is related to an internal setting and you will need to reset your TV. You can try this last-resort solution if you have exhausted all other options.
If this doesn’t work, you may need to contact your TV’s manufacturer for further assistance. This could indicate a manufacturing defect within the TV, and your warranty likely covers the cost of replacement.
