LG TV No Signal (How To Fix It FAST!)

Is your LG TV showing a “No Signal” error message and you’re wondering how to fix it?

Fortunately, there is a quick fix that should fix about 90% of LG Smart TVs that show “No Signal.”

And if that solution doesn’t work, we put together a complete troubleshooting guide to help you solve the issue.

How To Fix No Signal on LG TV

If your LG TV is showing a “No Signal” message, you must reset it. Unplug your TV from the wall outlet and wait 60 seconds. While the device is disconnected, press and hold the power button for 30 seconds. Then, wait a minute and reconnect your TV’s power cable.  The TV will soft reset, and your LG TV should display a signal again!

Check Input Source

Oftentimes, the fix to this problem is very straightforward. As you may know, every TV includes several HDMI ports so you can use multiple devices. You may have plugged your connected device into the wrong input, or your television is on the wrong input source.

Verify that your connected device is plugged into the same input source you selected on your LG TV. Skip to the next step if this doesn’t fix your problem.

Switch Input Ports

Since your LG TV has multiple HDMI ports, you can try a different one to see if it fixes the issue.

Make sure you change the input source on your television to the one you plugged the external device into, or else it won’t work!

If you’re still having issues after trying the other input ports, the next fix should help you.

Check The HDMI Cable

After checking the input source and trying different ports, you should ensure that the HDMI cable is plugged in properly — on both the television, and your device.

It may have come undone without you even realizing; I can’t tell you how many times I’ve tried different troubleshooting methods just to realize the HDMI cable was slightly loose.

Try A Different HDMI Cable

If the HDMI cable is plugged in all the way and you’re on the correct input source, it may be a problem with your HDMI cable.

HDMI cables don’t last forever; it may have rusted, broken internally, or the ends have been damaged.

This may also fix your television if it has no sound, which is another common issue.

NOTE: If you don’t have a spare HDMI cable around, I’d recommend trying the other troubleshooting solutions before buying a new HDMI cable.

Check In and Out Labels On The TV

There are two HDMI ports on LG TV’s: in and out. Both of these serve completely different purposes!

HDMI In means it’s receiving an input signal. This is where your HDMI cable should be plugged in.

On the other hand, HDMI Out means it’s sending an output signal. This is where you can send the picture from your TV to another device.

Restart Your LG TV

Every once in a while your TV will need a simple reset for whatever reason.

To do this, turn your TV off then unplug the power cord from the power outlet.

Wait about one minute, then plug the device into the power source and turn it back on!

Try A Different Device

If you’ve tried all the previously mentioned solutions, it’s time to try a completely different device to see if it’s a signal issue.

Plug in any device you have lying around, whether it’s a Firestick, Apple TV, or PS5.

If it picks up a signal, the problem is with your previous device, not your TV!

You can confirm this by plugging in the device in question into a different TV. If it’s still not working, it’s definitely a device issue and not a TV issue!

Disconnect All HDMI Cables

Most TVs have multiple HDMI cables plugged in at the same time.

While this shouldn’t be a problem, it can sometimes become too much for your LG TV to process.

You should unplug each HDMI cable from the TV, wait about 5 minutes, then plug them in one by one.

Factory Reset Your LG TV

Lastly, you can factory reset your LG TV if none of the above solutions helped you out.

A factory reset will delete all of your account settings and applications, so make sure you’re certain you have everything you need off of the device prior to the reset.

Here’s how you can factory reset your LG TV:

  1. Click the Settings button on your remote control.
  2. Scroll until you see All Settings then select it.
  3. Choose General then Reset to Initial Settings.

NOTE: Resetting your LG TV to factory settings should be a last resort, as it will clear all of the data off your device.

Why Does My LG TV Say No Signal?

There are several reasons why your LG TV may display a no signal message.

Weather Issue

Sometimes, factors outside of your control like the weather will affect your signal.

While there isn’t much you can do, try resetting your cable box and television!

It may help reset the connection for when the weather improves.

Broken Motherboard

If you’ve tried all the troubleshooting strategies above without help, your motherboard may be faulty.

Any electronic device can give out, so it wouldn’t be a shock if it happened to your television as well!

You can either consult with a professional to diagnose the problem, or go buy a new television.

Input Issue On Device

Your cables need to be entirely plugged in to have a strong signal.

Check your HDMI and power cables to see if anything’s loose and plug them in fully.

NOTE: This happens all the time mainly if you have young kids or pets, so double check on those wires!

Weak Signal Quality

There are times when the broadcast will have a weak signal.

No matter how strong their connection is, this causes a poor signal to every viewer.

If the original broadcast has poor quality, then the receiver will too. There’s no way around it!

To check this, ask your neighbor if they’re experiencing similar issues or not.
