LG TV Red Light blinks three times

When LG owners acquire a new TV, they frequently discover an issue such as LG TV Red Light Blinks Three Times and Shuts Down. If you are a victim of such an issue, we have listed a few options for you.

This typically indicates bad power (the board, transformer, or caps) or another component, such as the backlight, which commonly malfunctions in such a way that it attempts to extract far more power than the power rail can deliver.

There are various ways to resolve the three red lights flashing on your LG TV, and we’ve compiled them all into one easy-to-follow guide so you can get back to viewing your favorite shows.

Every LG TV has a little light on the front that blinks every now and then. This blinking is generally just temporary when the TV is turned on or when you use the remote. When your TV light begins to blink on its own and refuses to stop, you know it is attempting to tell you something. This tutorial will explain why your LG TV light is flashing so you can choose the best solution for you.

An LG TV with a flickering light implies an internal problem. The hue of this light changes depending on the model. A factory or hard reset can remove software faults caused by a power surge or loss. Otherwise, faulty circuit boards must be rectified or replaced.

Possible Reasons:

Here’s the issue: when you switch on your LG TV, it flashes three times with a red light before shutting down. You could even see the LG logo display briefly before swiftly disappearing. It remains blank no matter how many times you try to turn it on.

An electrical malfunction with the power board is the cause of your LG TV flashing three times before shutting off. It’s almost certainly due to bad capacitors.

LG TVs frequently require new power boards or capacitors after only 3-4 years. If you are experiencing this issue, you may have had your LG TV for several years. The bad news is that you’ll need to invest a few pounds to repair it yourself, but it’s not too expensive. If you fix it yourself, you’ll need to know a few things about power boards, but you’ll save more money in the long run.

Nonetheless, here are a few approaches you may take to try to resolve this issue.

But first, here’s something crucial:

If you’re seeking strategies to save money on TV repairs, keep reading because we’ll show you how. However, if this is a major problem that requires immediate attention, it is recommended to contact a professional technician who can assist you in repairing your TV in no time! Some brands/shops even provide free service while under warranty; however, if you open the chassis or any other element of your set (even before) – there is a risk it will no longer be covered under warranty, so be aware of this as well.

How to fix this issue:

1)Disconnect the power:

LG is fully aware of the power board issue, and they have some recommendations for consumers who are experiencing it. However, this is merely a temporary repair that will allow you to view your LG TV for a brief amount of time.

To test this solution, disconnect your LG TV from the wall and keep it unplugged for 6 hours to allow the internal caps to drain. Reconnect it and check if it turns on.

2)Repair the Power Board:

You should always try to take your TV to an LG professional. An LG engineer will be able to simply replace your power board, but it will not be inexpensive. In actuality, this sort of repair will cost you at least £200. When you consider that a new LG TV can be purchased for roughly this price, it may be worth sucking it up and purchasing a brand-new TV set if you’re not confident in attempting to repair it yourself.

3)Hold the Power Button:

Another solution is to unplug the power line from the wall and then hold down the power button for 10 seconds before connecting your TV back in. This modification may allow you to get some short-term usage out of your TV.

4)Replacing faulty capacitors:

Assuming your power board is the source of the problem (which it most likely is), you may disassemble your LG TV and inspect the capacitors. The capacitors should be flat on top, but if they seem bulged or domed, you’ll need to change them to see whether they’re the source of the problem.

You’ll need to follow the following steps:

  1. Remove the screws from the back of your LG television. On the back of your TV, there should be 12-16 screws. Unscrew all of them and store them safely.
  2. You should now be able to remove the back of your television.
  3. Take a photo of your power supply. This will allow you to use it as a reference when reassembling your television.
  4. Using a simple tug on the connecting clip, remove all power harnesses (not the wiring)
  5. Remove any screws that are keeping the board in place.
  6. You must now identify the faulty capacitors. You may accomplish this by searching for any evidence of swelling or leaking at the top. Don’t be concerned about the huge capacitors (they seldom fail); instead, concentrate on the smaller ones.
  7. Polarity exists in capacitors. This implies that they, like a battery, have a positive (+) and a negative (-) side. Before removing any capacitor, make a mental note of which side the white stripe of the capacitor faces. The replacement capacitor must be installed in the same direction as the old one. Snap notes or take a photo, otherwise, your TV will be ruined.
  8. Turn your power board over and look beneath to see where the faulty capacitors are.

There may not be a need to replace the capacitors so make sure you have tried the other solutions to cross out their possibility, so you don’t have to spend your money on capacitors when you didn’t need them.


In conclusion, the methods and solutions discussed above will be able to help you fix this issue and with the knowledge of why it is happening, you will know better if it happens again.

You should always contact an LG representative if you are having trouble yourself as they can help resolve your issue fairly easily and quickly.
