LG TV Light Blinking (Red/Green/Blue) & Won’t Turn On Fix

Most LG TVs eventually have the same problem: the light flickers and the television won’t turn on.

After seeing countless cases of LG TV owners claiming to have experienced this issue, we decided to investigate and offer troubleshooting solutions to help you out.

Fortunately, there is a quick fix that should fix about 80% of LG TVs that have blinking lights and cannot turn on!

How To Fix An LG TV Light Blinking But Won’t Turn On

An LG TV that has a light blinking but won’t turn on generally indicates an internal failure. The color depends on the model and issue at hand. To fix this, a soft restart can resolve any temporary issues. If that doesn’t work, you may need to repair or replace the circuit boards.

Perform A Soft Restart

If your LG Smart TV has a red, blue, or green light blinking and won’t turn on, the television is most likely having an internal malfunction.

You’ll want to fix this by performing a soft reset of the TV:

  1. Unplug the TV for an entire minute.
  2. While it’s unplugged, press and hold the power button on the LG TV for at least 30 seconds.
  3. After 60 seconds, plug the television back in.

After performing the soft reset, the television will power back on and any blinking lights should be fixed!

NOTE: This won’t work if you hold the power button on your remote control; you need to press the button on your TV.

Repair The Power Board

If a soft reset didn’t work, repairing the power board on the LG TV is the next step. It’s recommended to have a professional fix this.

An LG TV expert can easily replace your power board, but the cost will be substantial. In fact, you should budget at least $200 for this kind of repair.

If you’re not very confident about attempting to fix it yourself, it might be worth purchasing a new television when you consider that you can buy a new LG Smart TV for roughly the same cost!

Overheating Issues

When a television overheats, it acts the same way an internal malfunction would!

It will shut down, and the light will blink to indicate something has gone wrong — which is a preventative measure.

To fix this issue, perform a soft reset as previously mentioned:

  1. Unplug the TV for an entire minute.
  2. While it’s unplugged, press and hold the power button on the LG TV for at least 30 seconds.
  3. After 60 seconds, plug the television back in.

After performing the soft reset, the television will power back on and any blinking lights should be fixed!

Circuit Board Issues

Regarding internal components being damaged in a television, circuit board issues make up many of those issues.

Since the circuit board is responsible for transferring voltage inside the LG TV, if it doesn’t work properly, the television won’t either.

Most commonly, a power strip issue will be a worn capacitor. These prevent harmful currents from harming the TV’s other parts.

If that’s the issue, they are affordable and relatively simple to replace.

A worn capacitor will change shape, which is the most important thing to look for. It will go from looking flat or cylindrical to having a round top and a bulbous shape. There are so many capacitors on the power strip that it is easy to tell which one is worn out.

LG themselves have acknowledged that some of their television models may have a faulty power cable, which is why specific models (listed below) are eligible for a free replacement board.

Here are the models eligible for a free replacement circuit board:

  • 2016: OLED65E6, OLED65G6, OLED77G6
  • 2017: OLED65B7, OLED65C7, OLED65E7, OLED65G7, OLED65W7, OLED77G7, OLED77W7
  • 2018: OLED65G8, OLED65W8, OLED77C8, OLED77W8
  • 2019: OLED65W9, OLED77B9, OLED77C9, OLED77W9

Factory Reset The LG TV

If you’ve exhausted all the other troubleshooting solutions, it’s time to factory reset your LG Smart TV.

Here’s how you can do this:

  1. Press the “Home” button on your remote control.
  2. Select “Settings” near the screen’s top right.
  3. Go to “All Settings” then “General”.
  4. Press “Reset to initial settings”.

NOTE: This will remove all applications and account settings from your television. Please note any important information before factory resetting the TV.

What causes the LG TVs light to flicker?

The cause of the blinking light on an LG TV will depend on what color light is blinking.

It’ll be red, green, blue, or white, and here’s what causes each.

LG TV Blinking Red Light

Most of the time, a red blinking light is used for the above errors. When the TV is off but still getting power, most of them show a solid red light.

LG TV Blinking Green Light

Most of the time, a solid green light means that the TV is on. Some models, though, will use a green flashing light instead of a red flashing light to let you know that your TV has a serious problem.

LG TV Blinking Blue Light

Some LG TVs have a blue light that flashes when the TV is being turned on. If the TV won’t turn on and the blue light keeps flashing, it means that it is still trying to turn on but can’t.

When this happens, there is a possibility that the power supply is broken. You should try plugging the power cord directly into the wall or a different power outlet. Most of the time, this blue light will change to a flashing red light when there is a problem inside the TV.

LG TV Blinking White Light

Newer LG TVs are more likely to have a white light that turns on when the TV is turned on. This can be switched out for the green light on other models.

If your LG TV has a flashing red, green, blue, or white light, you should try one of the above solutions.

Final thoughts

That’s everything you should know about an LG TV Light Blinking.
