Below are ways to fix the problem of blinking red light on your LG TV set:

Do a Hard Reset

Performing a hard reset will help clear small errors from the TV’s memory, but is one of the only options if the screen is not coming up. This reset will also help secure all of your downloaded content and saved preferences. Follow the steps below to do the hard reset:

  • Switched off the TV and remove all connected devices.
  • Disconnect the TV from its power source.
  • Press the power button down on the TV (not the remote control) for about half a minute.
  • Switch on the TV back after 10 minutes.
  • Ensure the TV is working perfectly and reconnect all disconnected devices.

If the hard reset process didn’t work for you, try a factory reset. 

Do a Factory Reset

Doing a factory reset will erase all downloaded content and your saved preferences unlike performing a hard reset, so it is not usually recommended unless you are left with no other option.

Although, if you detect a hardware issue, it is easier to fix than opening the back of your TV. Follow the guidelines below step-by-step:

  • On your remote control, press the ‘Home’ button.
  • Go to ‘Settings > General > Reset to Initial Settings’.
  • Prompted to enter a code? Default code is usually ‘0000’ or ‘1234’.
  • Attest the factory reset has been done.
  • Hold on for the TV to fully reboot after a few minutes to see if it is working again.
  • To complete the setup, follow the on-screen instructions.

Fix LG TV Blinking Red Light Issue By Ensuring Your TV Is Not Overheated

Is your TV overheated? You are not sure because it also has the same indication as to if there were an internal failure of one of the circuit boards. With a flashing light, the TV will shut down to indicate there is a problem somewhere, but this is a mechanism to protect and prevent damage from the excess heat. Follow the steps below to ease the stress of overheating on your TV set: 

  • Perform a hard reset, mentioned above (the 10 minute period of waiting should help to cool the TV down). However, if it is still overheated, leave it unplugged for a night instead.
  • Determine why the TV is overheated in the first place.
  • Ensure the vents at the back of the TV are opened and free of dust.
