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

  • 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 closer to your TV.
  •  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  • If you’re still having trouble, your router’s firmware may be outdated.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.
  • Finally, if none of the above solutions works, you may need to go to an authorized repair center to get checked your LG TV.

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 the LG smart 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. This results in disturbing sound output also.

  • 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 external speakers.

Image retention:

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

It can occur when an image is displayed on a screen for a prolonged period. This can cause the image to become “burned-in” to the screen.

If you’re experiencing this issue, you should try changing the display settings or power cord on your LG smart TV.

3. LG TV Not Responding To Remote

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.

4. LG TV No Sound

There are a few possible explanations if your LG TV has no popping sound. One possibility may be LG TV turns on but has no picture or sound. The solution to this problem is the following.

  • First, check to ensure that the volume is turned up on your TV and the external speakers (e.g., cable box, DVD player, etc.) you are using.
  • 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.

  • Another possibility is that one of your display drivers is corrupted. You can try updating your drivers to see if this fixes the problem. If not, you may need to uninstall and reinstall the drivers or remove the batteries.
