LG TV wont turn on red light flashing 3 times

When the LG TV won’t turn on red light flashing 3 times in a row, you can be sure that this is a prime power problem indication.

In most cases, the problem can be solved with some easy steps but in other cases, this might be a sign of a faulty hardware component. Let’s learn more!

When LG TV refuses to turn on and the LED flashes red 3 times, users should first inspect the power source of the device and whether the power cable is connected properly. The solution includes a power cycle and, if necessary, a replacement of the power adapter.

Let’s learn more about what the 3 red flashes mean on LG TV:

What Does It Mean When LG TV Won’t Turn On 3 Blinks?

what means lg wont turn on red light

If your LG TV refuses to turn on and its LED flashes 3 times in a row, then it means that there is an electrical fault with the power board.

There’s a chance that this problem is caused by faulty capacitors that require technical skills to be replaced.

Here are other causes for the 3 red light blinks from your LG TV:

  • An issue with the power adapter.
  • A problem with the power adapter port on the LG TV.
  • No power from the power source.
You can take on these three possibilities by yourself and resolve them if possible.

Keep in mind that if the problem is related to a fault with the power board, you should deliver the TV for repair instead of trying to solve the problem at home.

How To Fix When LG TV Won’t Turn On Red Light Flashing 3 Times?

In the guide below we’re going to attempt every possible move against the problem by using a chronological solution list.

We strongly recommend performing ALL solutions in order before drawing conclusions about the state of your LG TV. Let’s jump right in!

Solution #1 Reconnect LG TV’s Power

A quick and effective solution to the problem with your LG TV is to reconnect the power.

If the issue is temporal and the three red blinks indicate a temporal electricity outage, you will be able to solve the problem by detaching the TV power adapter and then connecting back.

Follow these instructions to properly reconnect your LG TV’s power adapter:

  1. Grab the remote and point it towards the TV.
  2. Press and hold the power button for 3 seconds.
  3. Next, disconnect the power adapter of the TV.
  4. Count to 10 and reconnect the power adapter.
  5. Check if the same problem persists.

This method also discharges the TV so in most cases, it turns out to be effective!

Tip: Waiting for longer when the TV is disconnected provides a better power cycle!

Solution #2 Soft Reset With Power Button

If simply reconnecting the power didn’t fix the issue with your LG TV, there is an alternative solution.

You can perform a soft reset on the device, using the power button on the side or back panel (based on the model).

Here’s how to perform a soft reset on your LG TV using the hardware power button:

  1. Grab the remote, point it towards the TV and press the power button.
  2. Unplug the power adapter of the LG TV.
  3. Wait for 10 seconds.
  4. Locate the power button on the back or side panel of the LG TV.
  5. Press and hold the power button for 60 seconds.
  6. Release the power button.
  7. Plug your TV back to power and check if the issue is resolved.
Notice: Repeat the steps again if the issue is still there!

Solution #3 Plug To Different Source

The origin of this problem with your LG TV may have something to do with the power source.

If the TV isn’t withdrawing enough electricity to start up, it will indicate this problem with the three problematic blinkings you’re seeing on the LED.

Assuming that you’re pretty familiar with how to reposition your LG TV and plug it into a different power source, we leave that up to you.

Just make sure that the new power source for your LG TV delivers sufficient power and that there is no danger of a shortage.

Test the new power source by plugging another device in before the LG TV.

Note: A faulty power source tends to make a sound (buzzing noise), whenever a device is plugged in.

Solution #4 Replace The Power Adapter

The blinking that your LG TV makes to notify you of a power problem may be related to a fault in the power adapter.

There is not much that you can do to solve a problem with the power cable, and users simply replace the entire unit.

All LG televisions use a standard power adapter so you shouldn’t have a hard time finding a replacement.

You can use a replacement from your home or purchase a new one. The only thing you must be certain of is that the power adapter is functional.

You can for instance disconnect the current power adapter and take measurements.

If all entries seem to match, feel free to install the new power adapter and test your TV!

Note: It’s recommended to purchase a new power adapter since second-hand or used adapters can bring even more faults with the LG TV.

Solution #5 Replace Faulty Capacitors

Before delivering your LG TV for repair, there is one last thing you can attempt with the goal of resolving the problematic blinking.

Your LG TV will also notify you of a power fault with the LED if there are blown capacitors on the motherboard.

Although this is quite a challenging solution, using the steps below you can do it at home!

What Tools Do I Need For Replacing Capacitors?

You’re going to need the following tools:

  • Wire cutters.
  • New capacitors (LG TVs use Aluminum Electrolytic Capacitors).
  • Pliers.
  • Soldering iron (can be found for around 15 bucks on Amazon).
  • A Phillips-head screwdriver.

Once you have all of these tools, here’s how to identify and replace blown capacitors:

Alert: Opening your LG TV voids the warranty immediately!

  1. Locate and remove all screws on the back of your LG TV (should be around 16).
  2. Pop the back panel of your TV and remove it.
  3. Take a picture of the TV’s motherboard and the configuration of all wires.
  4. Remove all harnesses on the TV’s connector clip, using a simple tug.
  5. Undo all screws holding the motherboard down.
  6. Take a look at the capacitors (blown ones have their head wide open).
  7. Once you’ve found the faulty capacitors, remember the polarity and positioning.
  8. Grab the new capacitors and put them the same way as the old ones.
  9. Flip the motherboard once the new capacitors are installed and use the soldering iron to solder them up.
Tip: You may need assistance from a friend or family member to keep the motherboard intact while you head up the leads to tighten up the capacitors.

Solution #6 Get The Motherboard Checked

If replacing bad capacitors couldn’t help with the LG TV won’t turn on red flashing 3 times the problem either, then the issue is most likely to be with the motherboard.

As with all pieces of technology, your LG TV’s hardware components might have come to an end.

At this point we can’t tell for sure which component has to be repaired, you’ll learn that after servicing the TV.

However, if your LG TV’s warranty is still intact, you should attempt to use it since such problems can’t be caused by users’ actions.

Note: When contacting a support team, make sure to mention what you’ve already tried!

Quick Recap:

Hence, the 3 red flashes on an LG TV that won’t turn on mean that there is a power failure that could be related to the power input, power adapter, or power source. Users need to inspect these three factors to draw a conclusion as to why the problem appears.

Wrapping Up:

Now that we know why the LG TV won’t turn on red flashing 3 times and what the solution includes we can understand whether we need servicing for the TV or some troubleshooting at home.

It’s important to remember that opening the TV voids the warranty so in case it’s still intact the best move would be not to touch anything and leave the work for the professionals.
