Here’s the exact game plan to fix your LG TV when it has stopped recognizing an HDMI port:
- Check for common issues
- Check the TV hardware connections
- Check the TV software
Let’s get started.
How to fix an LG TV when it says no signal
1. Check the external device power
Check that your game console or media center is powered on and the power cord for the external device is connected correctly. Also, make sure it is not in a power-saving mode.
2. Check the input source selection
A wrong input source selection could cause your TV to not display a signal. Most TVs have several HDMI inputs and can connect to multiple devices.
Check that the TV is set to use the correct input source.
How to select an input source on an LG Smart TV :
- Check the back of your TV to find the HDMI input number for the device you want to watch on the TV.
- Turn on your TV and grab your LG remote control.
- Look for the Input button on your remote and press it.
- Highlight the required input source.
- Press OK.
3. Power cycle the LG TV and check the HDMI ports
Loose HDMI connectors can commonly cause a TV to display the HDMI No Signal error. For example, one of the connectors may have become dislodged from an HDMI port or is not inserted correctly, leading to a disruption in the signal. Luckily, it’s a relatively easy fix.
This is also an excellent opportunity to power cycle the TV and clear the memory in case something has been erroneously set.
How to power cycle an LG TV and reseat the cables:
- Note the port number where each HDMI cable is plugged into the back of the TV.
- Now, disconnect the HDMI cables from your TV (yes, all of them!).
- Power off the TV and remove the power cord.
- Wait at least 30 seconds, then reconnect the TV power cord.
- Connect all HDMI cables to the TV to the appropriate ports. If using directional HDMI cables, connect the ends of the directional HDMI cables to the appropriate source.
- Turn the TV power back on and recheck the signal.
4. Switch to another HDMI input
If there is still no signal, try switching to another HDMI port by physically moving the cable to a different port on your TV. The TV Source settings must also be set to the new HDMI port. (See Step 2 again for a reminder on how to do that.)
5. Run an LG HDMI Self-Test
Did you know that some LG Smart TVs have a built-in HDMI Cable Test function that can help you diagnose any issues with your HDMI cable? It’s a handy feature but might not be available on TV models manufactured before 2020.
How to check your cable with LG HDMI Self-Test:
- Ensure the HDMI cable is properly connected and the external device is turned on.
- Select the HMDI port that the external device is connected.
- Open the user menu by pressing the Settings button on the remote until the menu appears.
- Select the Support menu at the bottom.
- Select Quick Help
- Select Check Items
- Now select Check the status of the TV
- And finally, select Check RF/HDMI
- Select Start Diagnosis
- Wait for the test to complete
- There are two possible results:
- OK – this means the cable is in good condition
- NG – this means the cable is No Good.
- Select Learn More for a list of reasons that could cause the problem.
If the cable diagnostic test result is NG, this is usually resolved by replacing the cable with a certified HDMI 2.1 cable.
6. Try Connecting Another Device
If you are having trouble getting your TV to display properly, a few different things could be the cause. Say your TV works fine when other devices are connected but experiencing issues with a specific external device. The external device itself may be causing the problem. We suggest contacting the device manufacturer and requesting a repair or replacement.
However, if you are experiencing problems with multiple devices when attempting to connect them to your TV. The issue is likely with your television. Continue on with the following steps to try correcting any software issues.
7. Update the TV Firmware
Smart TVs offer a ton of entertainment value and can make watching your favorite shows and movies super easy. But like any other techy device, they can sometimes run into problems.
One such problem is outdated software. If your TV uses outdated software, it may not perform as well as it can. That could mean your TV won’t be able to do certain things, or you might experience annoying glitches while trying to watch something.
But don’t worry! There’s an easy fix. Just check for updates! You’ll be able to enjoy all the latest features and functions. Plus, your TV will run smoother, and you won’t have to deal with annoying glitches.
To check for updates, follow these steps from the manufacturer at ‘How to update an LG Smart TV‘.
8. Factory Reset the TV to the default settings
Problems may arise with your LG TV apps, the internet connection, or the settings, and could cause the TV not to display a signal.
If you’ve tried all the other solutions and the problem persists, resetting your TV to its factory settings can help. But note, this should be the last thing you try, as it resets your TV to how it was when you brought it home. Erasing any profiles and downloaded apps.
Determine your TV WebOS version and follow the steps below to reset your LG TV:
How to reset an LG TV to Factory Reset:
- On your LG TV remote, press the Settings button
- Select All Settings
- Select Support
- Select Reset to Initial Settings
- Select OK
