LG TV No Signal: How to Fix
Often, the problem could be caused by bad weather like snowfall, winds, or heavy rain. But, modern devices are designed to cope with and endure bad weather. So, in most cases, all you have to do is turn off and then turn back on the device.
When it is not caused by bad weather, the LG TV no signal message could be caused by TV hardware, in which case you could repair it or replace it. In most cases, the problem lies in the connection via cables or cords.
However, if your LG TV has no signal, that could mean your HDMI connection is not working correctly. In other words, the TV is not getting a signal from an external device such as a Blu-Ray or DVD player.
Sometimes, the solution to this problem can be very simple. As you know, each TV has multiple HDMI ports. If you have chosen the wrong input channel, you have to select the correct HDMI port via the TV options.
Check out the number of the HDMI port you plugged the cable in. Then, check the HDMI port number you have chosen on your TV. If this doesn’t solve your problem, move on to the next step.
Switch Input Ports
As we said earlier, there are multiple HDMI ports on your TV. This means that you can not only connect multiple devices at the same time, but you also have a backup option. If one of the HDMI ports is not working properly, you can always switch to another one.
In this instance, you can switch input ports until the signal appears. Also, don’t forget to change the HDMI port number on your TV options, as we explained in the first step.
If you have checked all the existing HDMI ports, and the signal problem still exists, check out the next step.
Check HDMI Cable
The most common issue with the signal comes down to the HDMI cable. Sometimes the HDMI cable slips or is not inserted properly.
Just simply check whether the HDMI cable is inserted properly on both ends. The problem may still be there after completing this step. Therefore, try out our next step.
Replace HDMI (if necessary)
After you have confirmed that the HDMI cables are fitting tightly into the ports, you can check out the state of the HDMI cable itself.
HDMI cables don’t last forever, unfortunately. Sometimes there is internal breakage or damaged ends, or it simply just wears out and degrades.
You should keep this in mind when you encounter the LG no signal problem. In this case, the solution is simple – just replace the HDMI cable.
Almost everyone has more than one HDMI cable in their home. Therefore, just use another HDMI cable to confirm that this is the problem or purchase a new one. If this doesn’t solve your problem, don’t worry, we have more solutions for you.
Check For Damage on HDMI Pins
Unfortunately, sometimes you can’t solve the problem by buying a new cable. You might have a problem, not with cables, but with the HDMI ports.
It means that they are slightly damaged and can’t hold the HDMI cable properly, or pins and needles are bent or broken. In this case, a mechanic can solve your problem easily. Get your port repaired or simply switch to another HDMI port if you have one.
Check IN And OUT Labels On TV
Sometimes the HDMI ports are labeled as HDMI in or HDMI out. It means that these are intended for sending or receiving information.
Inputs usually receive, and outputs send audio and video signals. If the HDMI ports on your TV are labeled with “in” or “out” then make sure that you connected the HDMI cables accordingly.
Unplug the TV’s Power Cable
From time to time, your TV just needs a simple restart to continue working properly. You can try to unplug your TV’s power cable from the outlet. Wait for a few minutes, and then plug it back in. In a lot of cases, this simple trick solves not only the signal issues on your LG TV but also other issues.
Try to Connect the Other Device to the TV or the Device to Another TV
If you’ve tried every possible solution, you can test whether the problem is in your TV or external device.
To find out if the problem is indeed in your external device, you can try to connect it to a different TV. This could give you the answer you are searching for.
Disconnect All HDMI Cables
Having multiple HDMI cables connected at the same time could be too much for a TV to process. In this situation, you can try unplugging all of the HDMI cables.
Next, unplug the power cable from the TV and wait for about 10 minutes. Then, plug in the power cable and all the HDMI cables, one by one.
This step is your last resort if any of the above steps don’t help you. You can do the LG TV factory reset. Since the factory reset deletes all of your existing data and goes back to factory settings, do this only if you have tried all of the other solutions.
Here is how to perform a factory reset on your LG TV:
- Click on the Settings button on your remote.
- Scroll down and select All settings or Advanced settings, depending on the TV model.
- Select General and Reset to Initial settings. Keep in mind that all your settings will be deleted and restored to their original settings.

LG TV No Signal: Why Does This Happen
Sometimes there is a problem with your TV’s internal parts. If the issue is not in HDMI cables, other cables, or the external device itself, it could be a TV part.
In most cases, the motherboard could be broken or malfunctioned. In this case, you should consult with an expert who can fix or change this part of your TV.
In some cases, the problem is not in your devices or cables but with mother nature. No signal problems occur due to the bad weather conditions. Whether it is a storm or heavy rain, nature is unpredictable, and you can’t really change it.
However, you can try turning off your television or/and cable box for a while. In the meantime, the signal could come back.
Input Issue with Cable Box
The cable box itself may have some issues which can cause the LG TV no signal problem. In this case, check whether the cords are properly plugged into the cable box.
The best step is to unplug the cords from the cable box, wait for a couple of minutes, and plug them back in. This could be an easy solution to your problem.
Weak Broadcasting Signals
If the problem still exists after you have restarted the cable box, the problem can be weak broadcasting signals.
The first thing you should do is restart the TV. But, make sure to unplug it from the outlet, wait a couple of minutes, and then turn it back on.
Check all the cables to see whether they are connected properly. Some cables could be loose or halfway inserted.
Then you can go to settings. Find the channel tuning option, and select the manual tuning. Then, select the channel you are watching at the moment and check the signal strength. If the strength is below 50%, you might experience blurring or no signal message on your screen.
You can also ask the neighbors if they are experiencing the same issue. If they are, this is a problem on a higher level, and it doesn’t depend on your devices.
LG TV No Signal: Other Troubleshooting Methods
Check Resolution Output Settings
Sometimes the resolution output is set to automatic. And maybe your video resolution output doesn’t match the external device. For instance, if your cable provider delivers 1080p resolution, it might be recommended to select this option. However, you can always change this setting if you need a higher video resolution.
Reinstall Chipset and Graphics Drivers
Another thing that could cause problems is drivers not being up to date. You can try reinstalling the chipset and graphic drivers. This could solve your LG TV no signal problem.
In this case, you need to update your TV software. Every new update brings new improvements, including new drivers, fixes, and patches.
To update your LG TV follow the steps below:
- Press the settings icon on your remote.

- Here you can allow automatic updates or check for updates.
- Click the check for updates option. At this point, make sure your TV is connected to the internet. Otherwise, your updates won’t be installed properly.
- Once the update is finished, restart your TV.
Change the Turning On Sequence
Each of us has a specific sequence in which we turn on our devices. For example, maybe you turn on your TV first and then connect your cables and external devices. Sometimes you can solve the problem by trying a different turning-on sequence.
For instance, you can connect all your devices to your TV. Once the devices are ready, you can turn on the TV.
