10 Common LG TV Problems & Troubleshooting Guide

If you have other devices like smart TV, you may see the same issue on the home screen.

1. TV Not Connecting to Wi-Fi

There can be several reasons LG TV is not connected to the internet.

  • First, make sure that LG TV is within range of your router. If it is, check to see if your router’s Wi-Fi connection is strong enough. If not, you may need to move your router close to the TV screen.
  •  Another possibility is that something is blocking the signal between your router and TV. This could be something as simple as a piece of furniture or a wall. If you suspect this, try moving your router with the box cable and setting the TV screen closer.
  • If you’re still having trouble, your router’s firmware may be outdated. To check, go to the menu button and log into your router’s settings.
  • Wait to look for an update. If there is one available, be sure to follow the instructions carefully. Install the update according to your TV, and after this, make sure to reboot the TV as this will help the software to get into effect.
  • Finally, if none of the above solutions works, you may need to go to an authorized repair center to check your LG TV.

This will erase all your settings, so back up any important data first. To factory reset your TV, go to the settings menu and select “Reset.”

LG TVs are known for their sleek designs and high-quality displays.

However, some LG TV users have reported LG TV screen problems, including TV screen flickering, ghosting, and image retention.

Screen flickering:

  • Screen flickering can be caused by various factors, including loose connections in the HD set-top box, damaged hardware, or software glitches.
  • If you’re experiencing TV screen flickering, you should first check all of your TV’s connections to ensure they’re tight.
  • If that doesn’t fix LG TV problem, you may need to replace some of the hardware inside your TV or check the TV remote control.

You can also go to TV settings to make sure that’s what the major problem is.

Ghosting screen

Ghosting is another common LG tv problem caused by loose connections of HDMI cables or damaged hardware. All LG TVs come with at least two HDMI ports. This results in disturbing sound output also. You might face this issue with your LG TV in that there is no sound output from the speaker or not having no audio signals.

  • If you’re seeing ghosting on your screen, you should try tightening all of the connections to your TV and secure your internet connection.
  • If that doesn’t work, you may need to replace the screen or some of the hardware inside your TV, just the external speaker

Image retention:

Image retention is another major problem that is causing many smart TVs.

3. LG TV Not Responding To Remote

common LG TV problems

There are a few possible explanations if your LG TV is not responding to the TV remote. The solution for LG tv problems that won’t turn on is the following.   

  • First, check to ensure that the batteries in your TV remote are fresh and inserted correctly. If the batteries are low or inserted incorrectly, the remote may not have enough power to control the TV properly.
  • If the batteries are fresh and inserted correctly, the next step is to check the TV’s infrared sensor. The remote control sends out infrared signals to power inputs that are picked up by the sensor.
  • So, if the sensor is dirty or blocked, it may not be able to receive the signals properly and distract the power supply. To clean the sensor, use a soft, dry cloth to wipe away any dirt or debris gently.
  • If the infrared sensor is clean and unobstructed, the next step is to check the remote control for any physical damage. You can also check the properly connected HDMI ports because electronic devices have such a problem.
  • If the remote control is cracked, chipped, or otherwise damaged, it may not send the proper signals. In this case, you will need to replace the remote control.
  • If you have followed all of these steps and your LG TV still is not responding to the remote, you may need to contact LG customer service for further assistance.

  • If the volume is turned up and you still don’t hear any sound from internal speakers, try changing the audio output setting on your TV. This is important to match the audio cable you use (e.g., HDMI, optical, etc.).
  • If you have tried all these things and still can’t get any sound, there may be an issue with both external and internal speakers on your LG TV. This also happens due to a bad motherboard.

Try testing the speakers by connecting another device (e.g., your phone) to the audio input on LG TV. If you still don’t hear any sound, the speakers may be defective and need to be replaced.
