How to fix LG TV No Signal issue? Turn off all HDMI devices connected to the TV. Unplug the HDMI cables from the TV. Take a 60-second break. Plug all the cables back in. Step 1 Do the basic check first I always recommend this to everyone. Before engaging in any nonsensical activities, performing some basic checks can save you a lot of time. Here’s what you need to do Check cables and connections Make sure the HDMI cables and any other devices you use are properly connected and tightened. Select the correct input Check your TV’s manual or on-screen menu and choose the correct input. Power cycle the devices Power off all the devices such as cable box, DVD player, gaming console, etc. connected to your TV and unplug them from the power source. Wait for a minute and then plug them back in and power them on. Check for any service outages Contact your cable or satellite provider if there is an outage in your area. Try a different source if your source is set to cable or satellite, switch it and see if that changes anything. Or, try a different input device, like a Blu-ray player or game console. In some cases, you may need to restart your TV to recognize these devices after making these switches. Check the source device Connect a different device to your TV and see if the issue is with the device or with your TV. Step 2 Going Deeper If your TV is still throwing the same pesky error at you, consider resetting the TV to its original settings or running an auto-program scan. ♦ Factory reset the TV I know what’s on your mind! Have no fear, the reset process is a simple one and won’t harm your TV in any way. It will only delete any corrupted files or newly installed software and revert the TV back to its default settings. However, here’s how to do it Press the “Settings” or “Menu” button on your remote control to access the TV’s settings. Navigate to the “General” or “System” settings option. Select the “Reset” or “Factory Reset” option. Confirm the reset action when prompted. WARNING resetting will erase all settings and preferences, including network and cable settings, custom picture settings, and audio settings. You will need to set up your TV again from scratch after the reset is complete. ♦ Run the Auto program’ feature Sometimes your TV just needs to be re-programmed. This feature is specifically designed to automatically change specific settings and typically fixes the signal issue within one or two attempts. Here’s how to do this Press the Home or Menu button on the remote. Select Setup or Settings. Select Channel. Select Auto Tuning or Auto Program. Select Start. Ensure that your device completes the scan to 100%. Failure to do so may result in some channels not appearing in the list. If you encounter a “not programmed” message, refer to this article for further assistance. Every model has its own unique approach to auto-programming. The instructions and terminology outlined in the guide above may not match your model. Step 3 Thinking outside the box Sometimes the obvious solutions just don’t work. In these cases, thinking outside the box and exploring alternative approaches are important. Let’s start with the common causes. If the problem is due to a loose cable, instead of simply checking the connections, try using a different cable altogether. A new cable can often resolve the issue if the old one is damaged or worn. You can also swap the input source. For example, switch from HDMI to coaxial cable. This will help you determine if the problem lies with the input source or the TV itself. Q1 Why does my LG TV display a No Signal’ message? The No Signal’ message on your LG TV typically appears when the TV is unable to receive a signal from the connected source, such as a cable box, gaming console, or antenna. It could be due to a loose cable connection, incorrect input selection, or a problem with the connected device. Q My LG TV says “No input detected” If your LG TV is displaying the “No input detected” message and advises you to check the external input, it means that it’s not receiving input from your HDMI source. There are a few things you can do to fix this issue Check that all of your HDMI cables are properly plugged in. If you’re using an HDMI splitter, make sure that it’s properly connected. Check your HDMI source Blu-ray player, cable box, etc. to see if it’s turned on and set to the correct input. Try a different HDMI cable. If you’re still experiencing the issue, you may need to factory reset your Sony TV. Q Why does my TV display this message only on specific inputs? It could indicate a problem with those specific input ports on your TV. In such cases, you can try using a different HDMI port or other available input options to see if the issue persists. If the problem persists across all inputs, it may require further technical assistance. Q My LG TV occasionally shows No Signal’ for a few seconds and then resumes normal operation. What could be causing this? It could be due to signal interference or a weak signal from the source device. Check the cable connections and ensure they are secure. If the issue persists, try using a shorter or higher-quality HDMI cable to minimize signal loss. Additionally, distance from the source device or obstacles between the device and the TV can also affect signal strength.
