It can be highly frustrating when you sit down on the couch after a hectic day to watch some football and your TV refuses to turn on. While your initial thinking would be to take a trip to the LG store, put a hold on it. Try some of these remedies yourself before you contact the experts.
Your LG TV can fail to turn on due to multiple reasons, including power plug/socket faults, remote issues, and motherboard failure. You can employ different methods to fix these issues, such as troubleshooting your plugs, sockets, TV remote, and maintaining your TV’s panels.
Knowing why your TV isn’t working and how you can fix it can prove to be an essential skill. You’ll save time and money and be able to watch your favorite shows again in no time. So, without further ado, let’s dive right into the main causes of the issue and find their relevant solutions.
Main Causes Of LG TV Not Turning On
There are various reasons why your LG TV may not be turning on like it’s supposed to. Let’s pinpoint these before we go on to our solutions so you can diagnose and understand the problem better.
Cause 1: Faulty Power Cable Connection
A faulty power cable connection is generally represented by your power light simply blinking but not turning on entirely. You should check your power cables and the power socket you generally use for your TV to see if they are damaged.
Cause 2: Faults In The Remote
If your power light is stable, but the LG TV itself is not turning on, it typically means that the issue lies with the infrared sensor of your LG TV remote. You can check the connection between your TV’s remote and TV by pressing random buttons on the remote to see if you get a response.
Cause 3: Faults In Internal Circuitry
This refers to defects within your LG TV’s internal components, such as the backlight, capacitors, or motherboard. These parts will have to be tested individually to see where the issue lies. You can perform this personally or contact a local technician to help you to try and fix these issues accurately.

Solution For LG TV Not Turning On
Here are some things you should be trying on your own before concluding that you need to replace the TV or spend money on repairs:
Solution 1: Check The Power Cable And Socket Connection
You should check the state of your power cable to determine whether it is hindering your TV from getting turned on. Sometimes, the problem can be as simple as a loose or faulty power cable.

Rather than directly going to a technician, you should take some time to try and troubleshoot your power cable issues manually. This means checking both ends of the plug and trying a replacement cable. If the replacement cable works, the issue was with your old power cable.
Also, check the power socket you have plugged your TV into. Plug your TV into a different socket to see if that fixes the issue. If it does, the issue was with the previous power socket.
Solution 2: Perform A Soft Reset
Another fix you can try is to drain your TV’s power – the power drain cycle is a soft electrical reset. This process is a soft hardware and software reboot as it clears unnecessary data and physical static, giving your LG TV a fresh new boot.
How To Soft Reset Your LG TV
Soft resetting your LG TV is the go-to solution whenever LG TV issues first arise. Here is how you can do that:
Step 1: Unplug your LG TV from the power outlet for around 2 minutes.

Step 2: Hold the power button on your TV (not the remote) for approximately 30 seconds.
Step 3: Plug the power back in and start the TV.
The soft power reset might be enough to allow your TV to sort out any internal software or electrical charge-related issues itself and begin functioning as usual again.
Solution 3: Check The Remote Signals
Sometimes, your TV may be working fine, but your remote controller’s signals cannot reach it to turn it on. You can start by troubleshooting your controller first and then check your LG TV’s signal reception.
How To Check Your LG TV’s Remote
While this may be an unlikely oversight on your part, your TV remote may have simply run out of power and needs the cells replaced. If the TV has not been receiving any signals from the remote, it obviously will not be turning on.
Remove the back cover of the remote and replace the batteries. Then try to turn your LG TV on again. Alternatively, you can use a different LG TV remote or universal remote to test if it works and if the issue lies with your current remote.
Solution 4: Checking Your TV Signal Reception
The issue may lie within your LG TV’s signal reception. This can be due to an obstruction of signal or a fault in the infrared sensor of your LG TV. Obstruction refers to other objects and materials blocking the signal from your remote and can be dealt with by removing those items.
On the other hand, if your infrared sensors are faulty, you can try operating and turning your TV on using the physical buttons instead of the remote. If this works, then the issue was caused by your infrared sensors.
Note that the infrared sensor is generally located over the light on your TV that indicates power.
Solution 5: Check The Backlight
The backlight provides brightness to the images generated by your TV. If your LG TV turns on just fine, but the picture is not visible, it means your backlight may be broken and requires a replacement. Testing the backlight is a simple procedure.
How To Check For Faulty Backlight
You will need a flashlight to check for a faulty backlight. Turn your LG TV on and bring the flashlight close to the screen.
If you can see faint traces of images, then that means your backlight is faulty and needs fixing. If the light simply shines through the TV, the backlight is completely damaged. In that case, you can get the backlight replaced or repaired by a trusted source.
Solution 6: Check The Motherboard
If you have experienced any significant electrical surges or thunderstorms in your area, it is possible your LG TV’s motherboard has been fried. The motherboard is a delicate and vital component that handles the rest of the TV’s functioning.
How To Check For A Damaged Motherboard
The only way to test this is to lay the TV down and open up the back paneling. From here, you can check your motherboard’s sockets for any signs of damage. You can also connect the TV to the power supply and check if the motherboard connector pins are receiving the appropriate 5V voltage.
However, even if it’s broken, you will be happy to know that motherboards are relatively cheap; you just need to find one according to your TV’s model.
Solution 7: Check The Warranty And Contact Support
If all else fails, your best course of action is to check if your warranty is still valid. If it is, congratulations; you will be able to use it and get your compensation from the LG support team. Otherwise, depending on the type of damage and the amount needed to fix the LG TV, you might look into buying a new one rather than trying to fix a broken old TV.
