Your LG TV light might be blinking due to damaged capacitors, power boards, software issues, faulty motherboards, or not getting enough power. To fix these issues, you will either have to replace the damaged component or reset your TV.

Unfortunately, repairing an LG TV can be challenging and tricky for individuals without technical experience. Hence, this article will provide you with all the information you need about why your TV has blinking lights and what you can do to fix it.

Why Do LG TV Lights Blink?

If your LG TV is displaying blinking lights, the first thing you need to do is to determine what color it is and what it means. Usually, a red blinking light means that there is an issue with your TV. On the other hand, if your TV is displaying green/white or blue blinking lights then it is not a huge cause for concern.

Blinking Red Light

Here are the possible reasons why your TV might be displaying a red blinking light:

Reason 1: Internal malfunction

The red blinking light can indicate an internet malfunction in the TV. The internal issue may include a faulty WiFi chip, broken inverter board, damaged motherboard, or any broken internal component.

By displaying red blinking light, your TV could be trying to warn you about this issue. Therefore, I would recommend that you get your LG TV checked by a professional before the problem worsens.

Reason 2: Power fluctuations

If your power supply is fluctuating or has power outages, your TV will try to let you know through blinking red lights. If this happens, it is best to get your power supply checked and fixed before it damages any internal components of your TV due to fluctuations. Possible reasons for the power fluctuations can be power line damage or bad weather.

Reason 3: Power board

If a red light is blinking three times on your TV before shutting down, this is an indication that there is a problem with the powerboard. Since the power board of your TV is used to distribute voltage throughout your TV, this issue is very serious. The red light could very well be pointing at a faulty capacity or a blown main fuse and you need to get it checked out by a professional.

Reason 4: Overheating

If your TV is overheating, this will most likely be indicated by a red light blinking four times. Possible reasons for overheating might be a blocked air vent or direct sunlight. The easiest way to prevent your TV from overheating would be to clean the back air vents of the TV to allow for proper airflow.

Reason 5: Software

A software issue is also indicated by a red light blinking four times. The reason for software errors can be apps getting corrupted, sudden power surges, or just some software bugs. Before doing anything else, you need to ensure that your TV’s software is the latest provided by LG.

Blinking Green/White Light

If your LG TV is displaying a green or white light then you don’t have to worry. These lights usually indicate that your TV is turned on or on standby and that there is no internal problem causing any performance issues. Older models mostly use white light while some newer ones use a green one instead and both mean the same thing.

Blinking Blue Light

A blinking blue light usually means that your LG TV is turning on. However, if the light has been blinking for a while and the TV has not turned on, this would indicate a problem with the power supply of your TV.

Now that you’ve taken a look at what might cause lights to blink on your LG TV, let’s head toward what you can do to fix this problem:

Fix 1: Soft Reset

Power cycling or soft resetting your TV might be one of the most efficient methods to solve any issues which might have occurred when powering on the TV. Believe it or not but it can even solve bugs and other app issues.

Follow the steps I have laid down below to easily soft reset your LG TV:

Step 3: Press and hold the power button on the TV for about 30 seconds to dissipate any residual power.

Step 3: After that, wait a couple of minutes before your switch on your LG TV.

Fix 2: Warm up the Capacitors

If you are certain that the issue with your TV is with the motherboard or the capacitors, you can try heating them up before turning on the TV. This will allow the capacitors to work even if they are a bit damaged.

Grab a hair dryer and plug it near your LG TV. You will need to heat up the back of the TV where all the air vents are placed. Be careful to try this hack for about five minutes. If the TV does not turn on, you will have to replace the capacitors or motherboard.

I do not recommend replacing the capacitors by yourself if you do not have any prior experience doing so. A much safer option would be to call a technician to replace the capacitors. Also, capacitors are usually cheap, and you will only need to spend a little extra over the technician’s fee to get your TV back in working condition.

Fix 3: Factory Reset

A factory reset might be your best bet to take care of any serious software issues; a factory reset might be your best bet. Keep in mind that a factory reset will change your TV’s settings to the ones it had when you bought it. So save any important files you may have on your TV on an external drive before performing a factory reset.

Step 1: Press the Home button on the remote and press Settings.

Step 2: From there, navigate your way to General and then select Reset to initial settings. The software will then ask you for a PIN. If you have not changed it yourself, it will either be or

Step 3: Wait for the TV to completely reboot, and then set it up and look to see if this has solved the issue.

Fix 4: Customer Service

Customer support call team center

If you have not been able to diagnose the issue and none of the fixes you have tried have worked, the issue is most definitely one that concerns hardware. See if you have a warranty for the TV, as this will help you get the new TV for free.

Otherwise, you can call LG customer support to ask for a certified technician to come to your place and look at your TV to find the issue.
