How To Fix LG TV No Signal

LG TV No Signal

It is necessary to reset your LG TV if it is showing a “No Signal” message. Ensure that your TV is unplugged from the wall outlet and wait 60 seconds. During the 30 seconds, it takes to disconnect the device, hold the power button down for 30 seconds. Reconnect the power cable to your TV after waiting a minute.  As soon as the TV is softly rebooted, it should display a signal again!

1. Check Input Source

In most cases, the problem can be solved very easily. You can use a variety of devices with HDMI ports on every TV, as you may know. Perhaps you plugged the wrong device into the wrong input, or you set your television to the wrong input.

Make sure your LG TV is connected to the same input source as your device. If this does not fix your problem, proceed to step two.

2. Switch Input Ports

If the problem persists, try using a different HDMI port on your LG TV.

If your TV doesn’t recognize the device you plugged in, make sure you change the input source.

You should be able to resolve your issue by trying the next fix after you’ve tried the other input ports.

3. Check The HDMI Cable

When you have checked the input source and tried a variety of ports, you should ensure that the HDMI cable is plugged in properly – both on your TV and on your device.

It may have come undone without you realizing; I can’t tell you how many times I tried different troubleshooting methods only to realize there was a slight loose connection in the HDMI cable.

4. Use A Different HDMI Cable

The HDMI cable may be faulty if you have it connected all the way and are using the correct input source.

The ends of HDMI cables may be damaged, they may have rusted, or they may have been internally broken.

In addition to fixing no sound on your television, this may also resolve other common problems.

NOTE: The other troubleshooting solutions will probably work better if there isn’t a spare HDMI cable in the house.

5. Check-In and Out Labels On The TV

LG TVs come with two HDMI ports: an in and an out port. The purposes of these two are completely different!

It’s receiving a signal when HDMI In is on. You should plug in your HDMI cable here.

HDMI Out, however, means that it is sending a signal. A TV can be connected to another device via this method.

6. Restart Your LG TV

For whatever reason, your TV may occasionally require a simple reset.

The power cord must be unplugged from the outlet before your TV can be turned off.

You can turn the device back on after about one minute, after plugging it in and waiting.

7. Use A Different Device

You should try a completely different device if all the previously mentioned solutions have failed.

Use any device you have lying around, including your Firestick, Apple TV, or PlayStation 5.

The problem is not with your TV, but with your previous device!

If you plug in the device in question to a different TV, you will be able to confirm this. You’re definitely dealing with a device issue instead of a TV problem if it still doesn’t work.

8. Disconnect All HDMI Cables

There are usually several HDMI cables connected simultaneously to TVs.

Your LG TV will be unable to handle this sometimes, even though it shouldn’t be a problem.

The HDMI cables should be unplugged from the TV, then plugged in one by one after waiting about 5 minutes.

9. Factory Reset Your LG TV

Finally, if none of the above solutions worked for you, you can try factory resetting your LG TV.

You should only reset your phone’s factory settings if you’re out of options. This will delete all of your applications and settings on your account.

LG TVs can be factory reset in the following ways:

  1. On your remote control, click the Settings button.
  2. Select All Settings after scrolling until you see it.
  3. Select General, then Reset to Initial Settings.
