Common causes of an LG TV with power but no picture or sound

When a brand new LG Smart TV looks like it has sufficient power but there is no picture or sound, most of the time it is a simple fix that has to do with the settings, bad wires or cables, or an input device that is not functioning properly. 

Rarely, it is caused by a manufacturer defect, however, it is still possible. If it is because of a manufacturer defect, LG typically has a standard two-year warranty on all of their televisions. 

It may be a hassle to deal with, but just know that if the cause of your TV not having picture and sound is because of an internal electronic issue, there are processes in place to have your TV repaired or replaced at no cost to you. 

Also, if you happen to have picture and sound for a little while but then suddenly the screen goes black, this could be an indication of another problem different from having no picture or sound the entire time the LG TV is powered on. 

However, let us focus in on some potential problems and solutions that may be causing your LG Smart TV to power on with no picture or sound.

Power issues

If your LG Smart TV is not receiving enough power, it could still power on but then be unable to display the picture or produce the sound. 

This could be because the power outlet that the TV is plugged into is not supplying a sufficient amount of energy to properly power the television or that your home/apartment may be currently experiencing some electrical issues. If this is the case, you may want to try plugging your TV into a different electrical outlet and see if the problem gets resolved.

If it’s an issue that your entire home or apartment is experiencing, then you may need to contact your landlord or energy provider.

Faulty cables or wires

One of the most common reasons an LG TV may power on but fail to display picture and produce sound is due to faulty wires or cables. 

First, check the AC power adapter to make sure it is fully plugged into an outlet. Next, check every connected wire and cable to see that they are also fully plugged in and that they are plugged into the correct connections. 

Last, check all the wires and cables for any signs of damage that may have caused the wire or cable to stop functioning. If need be, you may need to purchase some replacement wires or cables at your local electronics store. 

Bad power supply board

If the issue is stemming from an internal electronic component like the power supply board, then you should be able to have your LG TV repaired or replaced as part of the standard two-year warranty that typically comes with an LG TV. 

However, if you bought the television used or from a private owner, you may be no longer covered under the warranty and will have to cover the cost of the repair yourself.

Capacitor issues

When it comes to potential internal electronic issues, if your LG television is powering up but there is no picture or sound, then there is a high likelihood that it could be because of the capacitor. Capacitors are electronics that store electric charges and then use them in the filter circuits. 

Again, if this is the issue, then it could be because of a manufacturer defect. You will need to contact the retailer where you purchased the television and see if you can exchange it for a different one or you will need to contact the manufacturer directly. 

Incorrect television settings

If everything seems to be running normally and there are no signs of damaged wires or cables, see if you can access the menu of your television by clicking on the menu button on your remote. This still should be able to popup even if your screen is black.

If not, then you may have a serious display issue in the actual television screen that needs to be inspected. When the menu pops up, go to settings and check to see if there is an energy save mode setting and if it is turned on.

Also, check the television’s picture mode, brightness, and backlight settings, and see if the television is on mute. 

Issues with the input device

If you are trying to use a PlayStation, Xbox, Roku, Satellite TV, or a cable box, you will want to make sure that the input device is properly turned on and that it is plugged into the correct input connection. 

Also, check to see that your LG TV is on the correct input mode.

For example, if you have an input device that is plugged in through your HDMI-1 port, make sure that your television is on HDMI-1 by pushing on the input source button on your remote control. 

Try this if all else fails

Powercycle the TV

Power cycling may not do anything, or it could potentially work on a whim. If all else fails, you should at least give it a try. First, go ahead and unplug the AC power adapter from its power source for about 15 or 20 minutes. 

Next, plug the TV back in and then force reset the TV by holding the power button located on the TV for 20 seconds. This may give your LG TV the reset it needs to automatically fix a software issue that may be causing the problem. 

Reset factory settings

Resetting an LG TV to its factory settings will delete all data, apps, software bugs, and any potential malware to bring it back to its default settings. To do this, simply go to the menu and find settings. In settings, you should see an option for “reset to initial settings”. 

Click on that and confirm. Once it resets, you can turn your TV on and see if the picture and sound are working properly. 

Check for any software updates

Smart TVs are kind of like computers. You may need to update the operating software on the television periodically. 

Updated software may have patches and fix any bugs that previous versions may have had. To check for software updates, again go to the menu and then the settings. In the settings go to the “About this TV” option. It should then display if there are any updates available. 

If so, go ahead and update the software by downloading the newest version. You will need to make sure your LG TV is properly connected to the internet before downloading the update. 

Contact the manufacturer

If all else fails, then it may be time to reach out to LG directly. If your TV is under warranty, then you may be able to return your television for a new one or LG may reimburse you to have your television inspected by a technician. 

If you are not covered under warranty, then you may need to contact a local television technician who can inspect, diagnose, and repair the TV for you. 

Since the television is no longer under warranty, you may need to cover any costs you may incur.
