Fix LG TV Flashing Red Light Issues

After understanding the red light on LG TV, you can dive into troubleshooting according to your specific situation. For your safety, if you’re not experienced with troubleshooting electrical devices, it’s advisable to consult a qualified professional.

Solution 1. Power Cycle LG TV

Remove the power cable from your LG TV for a few minutes, then plug it back in and try turning it on again. During the process, you can check whether the power outlet is working or not.

Solution 2. Check the Connection Cables

If your problem isn’t solved, please inspect whether the connection cords are damaged, or if they are plugged properly or securely.

Try disconnecting the cables from the TV to see if the flashing light stops. If it does, reconnect one cable at a time to identify the problematic device or cable.

Solution 3.Check Software Update

Sometimes, the red light on LG TV results from a software update stuck. Wait for 10-15 minutes to see if the TV is in the process of updating. If the light keeps flashing, unplug the TV for at least 30 minutes to reset it.

Solution 4. Check the Remote

Moreover, LG TV remote control malfunction or low batteries may cause your LG TV red light on but won’t turn on. If you primarily use the remote to control your TV, try pressing the physical Power button on the TV itself.

Bonus: You can also install a virtual LG TV remote on your mobile device to control the LG TV. Just make sure both devices are connected to the same wireless network. After finishing the pairing process, tap the onscreen Power button to turn on your LG TV.

Solution 5. Factory Reset the TV

However, if your LG TV red light stays on and all the mentioned steps can’t work out, go to Settings > General > Reset to erase all your personalized settings and data to factory reset your LG TV. While this reset procedure may seem thorough, it often resolves the majority of issues.

Solution 6. Advanced Troubleshooting

Besides, there are some advanced troubleshooting you can adopt, but note these solutions may void the warranty.

• Check the power board or main board for any capacitors that are swollen or bulging at the top. These are signs of faulty capacitors, which will need to be replaced.
• Check for any other visible signs of damage, such as burnt components or loose connections.
