LG makes some of the most reliable and cutting-edge TVs in the market, but sometimes the TVs can start to malfunction with blinking lights.
Believe it or not, these is part of the programming, and they’re an error code that can tell you a lot about what’s wrong.
Manufacturers use the blinking light to convey the issue that the TV is facing. These error codes all mean different things but they are normally very easy to fix at home without the help of a professional…
Let’s take a look at what the different blinking error codes mean and how you can fix them…
What The Different LG TV Blinking Codes Mean
LG TV’s red light starts to blink whenever there is an issue within the TV, although it should be noted that pressing buttons on the remote can also lead to a blinking light, and they should not be confused.
If the LG TV is blinking 2 times, it could mean that there is a problem with the internal components within the TV or a sudden power outage.
It is also possible that the TV’s internal components got damaged due to a sudden power outage or surge in electricity.
Some of the common component damage includes a worn out or damaged capacitor, damaged inverter board, circuit board, or motherboard.
It is also possible that some of the wires or components within the TV have worn out if the TV is old.
If your LG TV is blinking 3 times, it could indicate an issue with the circuit board or the power board.
The power board is responsible for regulating the voltage supply within the appliance, and if it is damaged, some parts of the TV won’t be getting the correct amount of electricity,
Some of the most common reasons behind this include a damaged capacitor, high electrical surge through the socket, faulty wires, damaged FETs and ICS, or a broken circuit board.
If your LG TV is blinking 4 times, it generally means that the TV is facing overheating issues or there is a software issue.
This can be because of a variety of reasons, including high voltage surge, damaged power board or wire, the TV has been running for a long time or if it has been placed in such a manner that heat is not being able to dissipate.
If the LG TV continuously blinks, it could indicate a software issue or some problem with the internal components.
How To Fix LG TV Blinking Codes?
To fix the issue behind the LG TV light blinking, you will need to inspect different elements of the TV to figure out the problem.
Even though the blinking codes give the users an idea of what the problem is, a lot of components can have interrelated issues which need to be solved.
Check Components And Power
Problem With The HDMI Cable
The HDMI cable is responsible for providing the visual input to the TV, if the wire has been damaged, broken, worn out or disconnected, the TV won’t be getting any signal and there will be a black screen. In some cases, this can also accompany the blinking red light on the TV.
To check whether the HDMI cable has a problem, disconnect the cable from the TV and its other source.
Check the ends of the cable for any damaged or loose parts. Check the rest of the wire for any damage as well. Now connect the cable back into the slots and make sure your TV is on the right source channel.
Now turn off the TV and turn it back on after 5 minutes. If the wire was damaged, then replacing it would be the ideal solution, they are quite inexpensive as well.
If there are more peripherals attached to the TV, disconnect them all and try plugging them in one by one, trying to isolate which one is the problem.
If this doesn’t work, you can also perform a hard reset on the TV to refresh its software.
Problem With The Remote
A lot of times, the TV can keep on blinking because of a sub in the remote or if it is broken and a button is stuck on the same position. Even though this sounds trivial, it can be easily ignored.
Make sure your remote is not damaged and if possible, replace the batteries in case it has been in use for quite some time.
In some cases, in case your LG TV has an IR sensor remote, you can check if it is working by pointing a phone camera towards its sensor. It should be noted that some iPhone models might not be able to detect this.
Proper Electrical Supply
To check whether your LG TV is receiving enough power, first begin with inspecting the power cord, disconnect it from the TV and the socket and check for any broken or damaged connectors.
They might have also become loose. Then the check the cord itself for any worn out wire parts.
If the power cord is not damaged itself, check whether the power socket itself has a problem or not.
Use a multimeter to check whether there is a current supply in the socket and try connecting another appliance of the same voltage rating that you know works in the same socket. If the appliance works, then the socket is working properly.
You can also perform a hard reset or a factory reset on the TV after connecting all the cables to see if it turns back on or not.
Overheating TV
It is not rare for a TV to get overheated, especially if it has been in use for a prolonged period of time and in a hot environment. If your LG TV is overheated, it will shut down with blinking lights to protect itself from any further damage.
Your TV can be overheated either due to an electrical current surge, prolonged use, especially hot weather conditions, damaged invertor board which is responsible for regulating the voltage supply within the TV, and if the TV is located in an area which has poor air circulation.
Turn the TV off for a couple of hours to let it cool down and try turning it back on again, you can also perform a hard reset in case the TV doesn’t turn on.
Software Issue Or Outdated Firmware
If you have been using your TV for quite some time, it is possible that you might have missed some software updates.
Just like any smartphone, TVs also get software updates regularly. If you don’t update it for a long time, it might stop working with blinking lights.
- Go to settings on your TV
- Go to ‘General’
- Select ‘About this TV’
- It will show there whether your TV needs an update or not
- Install the update and restart the TV
Internal Component Damage
Internal components in your TV can get damaged either due to being worn out over time or due to overheating, electrical surges or physical damage.
To check whether these parts have been damaged, you will have to open the back panel of your TV to gain access to them. Keep in mind that doing so can void the warranty of your product. It is recommended to only do so if you have experience with handling electrical equipment or if your TV is old.
Mother Board or Faulty Power Board
The motherboard is the brain of your TV, there are a lot of individual components on it, so just check for any physical damage to any part on the board.
They might be burnt, worn out or just broken. If the mother board is damaged, you will have to get it replaced and it can be a bit pricey.
LG did acknowledge that some of their TV Models can face issues with their circuit boards and in case any buyer faces such a problem, they can get a free circuit board replacement. These models were released between 2016 and 2019:
2016: oled65e6, oled65g6, oled77g6

2018: oled65g8, oled65w8, oled77c8, oled77w8
Up to sept 2019: oled65w9, oled77b9, oled77c9, oled77w9
Damaged Capacitors
The capacitors in a TV are responsible for a steady flow of voltage to the TV so that it operates normally. A red light flashing and the TV not turning on is one of the results of a failed capacitor.
You can check if the capacitor had failed by looking for any swellings on the capacitor. You can also use a multimeter to check if the current is flowing through it.
Soft Reset LG TV
You can perform a soft reset on your TV to clear it of any glitches in the software and refresh its operating system. A soft reset normally helps rid you of all the LG TV error codes.
- Switch off the TV and unplug it from the electrical socket.
- Press the power button for about 2 minutes
- While pressing the power button, plug the TV back into the socket and switch it on.
- Wait for 1-2 minutes before trying to turn on the TV using the remote.
Performing A Hard Reset
Performing a hard reset is like refreshing your TV’s memory and to clear out any bugs in the system.
The advantage of a hard reset is that it doesn’t delete any of your settings and it is quite easy to perform, just follow the steps below:
- Turn off your TV and unplug it from the socket.
- Hold the physical power button on the TV for 30 seconds
- Wait for 15 minutes
- Plug the TV back in and turn it on
This is a temporary fix and if it doesn’t work, try doing a factory reset.
Factory Reset LG TV
A factory reset should be your last resort, as this will delete all your saved data, including downloads.
This should be done if you think there is a hardware issue with the appliance. Follow the steps below to perform a factory reset.
Step 1: Press the ‘Home’ button on your LG TV
Step 2: Go to Settings, then General, then Initial Setting Reset
Step 3: It will ask for a code. ‘1234’ or ‘0000’ are the default reset codes
Step 4: Confirm Factory Reset
Step 5: Reboot your LG TV and see if it still has a blinking red light
Step 6: Follow the on-screen steps to complete the reset setup
It’s important to remember that performing a factory reset will help fix a blinking red light but it may not address other potential causes of this problem such as faulty wiring or build-up debris within the inner layers of your TV’s hardware components.
LG TV Blinking White Light
In some LG TV models, the white light has replaced the red light. In this case the white light can indicate any problem with the TV, from a bad power board to minor errors like problems with the HDMI cable.
A lot of the steps in this guiie can help you fix this issue and get your tv to work properly in no time.
LG TV Blinking Green Light
Similar to the white light, in some TV models, the green light has replaced red blinking light, and it could indicate any problem with the TV.
But if both green and red light are present, then the former simply represents that the TV is switched on and has power.
If the screen is blank, try to reset the TV and make sure you are on the correct input source.
What To Do When Your LG TV Turns On, But The Screen Is Black?
There can be a lot of reasons for a black screen. From loose HDMI cables with other peripherals or no network connection, outdated firmware, wrong picture and backlight settings or hardware issues like damaged LED screen or circuit board.
