- If your LG TV has no signal or your cable receives a weaker signal
- If there is a technical issue with your cable or satellite box

How to Fix LG TV Auto Tuning Not Finding Channels
Here are the troubleshooting methods that help you resolve the LG TV auto tuning not finding channels issue.
Adjust the TV Antenna
If the TV Antenna is not in the right place, then probably the auto-tuning will lose the ability to find channels. So, try to adjust the TV Antenna by moving it to a different/higher place or rotating it accordingly. If there is any physical damage to Antenna, you need to contact your cable provider for repair.
Check Signal Strength/Connection Type
Even if the TV Antenna is placed correctly, a problem may arise if the signal is poor. So, check if the signal strength of your cable/ satellite provider is stable or you can even contact the service provider for further assistance. If you’re using the coaxial connection, unplug your cable box and plug it back in.
Do Channel Scan on LG TV
If the TV’s tuner is not in use or the channels are out of tune, then you might not find channels on your LG TV. Here, are the steps to perform the channel scan.
 On your LG TV controller, press the smart button.
 Select the Manual Tuning or Auto Tuning option.
 Select your TV tuner. Using the left and right buttons, scroll through your channel lineup.
 Choose the channels that you want to add and click the option to add channels.
 If you want any other channels to be added or the channels you can’t find, you can manually type the channel name in the keypad.
 Once you added all the channels, exit the screen. Now, you will not have difficulty finding the channels.
Check Channel Input
Another reason for the LG TV auto tuning not finding channels is, that the input channels are not plugged properly or in the right way. If the input is connected wrongly, you will see no signal message while watching the channels. So, ensure to connect the input properly and make sure the wires are not loosely connected.
Note: It is recommended to change the input on the LG TV to the one you have connected a cable or satellite box.
Update LG TV
Because of outdated TV firmware, auto-tuning won’t be effective in scanning channels in some situations. So, you should update your LG Smart TV to fix the issue.
 Click the Settings icon on your LG TV remote.
 Select All Settings and click General.
 Tap About This TV and select Check for Updates.
 Click Download and Install, if an update is available.

 Turn on your LG TV and navigate to the Settings menu.
 From the menu list, select the General option.
 Then, click on reset to initial settings and hit the Confirm button, if required to confirm the process.
 Now, wait for a few seconds for the resetting process to get complete.
 Once done, see if you can find your channels. If not, you must contact the LG TV support team for further assistance.
Perform Manual Tuning
When auto-tuning does not work, you can manually tune and add the channels. Manual Tuning on LG TV allows you to tune the channels specifically to the transmitters your aerial is pointed toward. Here are the steps to do so,
