Flickering Screen on LG TV: What to Do?
Power Cycle the TV
- First of all, Unplug your TV from the power outlet.
- Now, Wait for at least 2-3 minutes for a complete power drain.
- Plug the TV back in and turn it on.
- This simple process can often resolve minor software glitches or clear any temporary data that may be causing the flickering issue.
Check Cable Connections
- Ensure that all cables (HDMI, component, coaxial, etc.) are securely connected to the TV and external devices (cable box, game console, streaming device, etc.).
- Loose or damaged cables can cause interference and result in a flickering screen.
- Try disconnecting and reconnecting each cable to ensure a proper connection.
Replace HDMI Cable
- If you use an HDMI connection and the flickering only occurs with a specific device, try replacing the HDMI cable.
- HDMI cables can degrade over time or become damaged, causing signal interference and flickering issues.
- Use a high-quality, certified HDMI cable for the best performance.
Check External Devices
- If the flickering only occurs when a specific external device (cable box, game console, etc.) is connected, the issue may lie with that device.
- Try disconnecting the device and see if the flickering stops.
- Check the device’s settings, firmware updates, and compatibility with your LG TV.
Adjust Display Settings
Sometimes, incorrect display settings can cause flickering issues on your LG TV. Here’s how you can adjust them:
- Press the “Settings” button on your LG TV remote.
- Navigate to the “Picture” settings menu.
- Adjust the brightness, contrast, and other display settings to see if it resolves the flickering issue.
- If the flickering persists, try resetting the picture settings to their default values.
Reset Picture Settings
- Access the Picture Settings menu on your LG TV.
- Go to the Advanced Picture Settings
- Look for an option to “Reset.”
- Confirm the reset and the TV will revert to the factory-set picture calibrations.
- This can eliminate any conflicting or incorrect picture settings that may be causing flickering.
Check for Overheating
Overheating can sometimes cause flickering or other display issues on your LG TV. If your TV is placed in an enclosed space with poor ventilation or is being used for extended periods, it may overheat and cause flickering.
- Turn off your TV and allow it to cool down completely.
- Check the vents and air intake areas on your TV for any dust buildup that may be restricting airflow.
- Use a soft-bristled brush or a vacuum cleaner with a brush attachment to gently clean the vents and air intake areas.
- Ensure that your TV has plenty of space around it for proper ventilation. Leave at least a few inches of clearance on all sides and above the TV.
- Consider using a cooling fan or air conditioning to help regulate the temperature in the room where your TV is located.
Update TV Software
- LG regularly releases software updates to improve performance and fix bugs.
- Navigate to the TV’s settings menu and check for available software updates.
- If an update is available, follow the on-screen instructions to download and install it.

- Access the TV’s settings menu and then go to the General.
- Locate the “Reset to Initial Settings” option.
- Follow the on-screen instructions to complete the reset process.
- Note that this will erase all your personal settings and preferences, so you must reconfigure the TV after the reset.
