Common Reasons Why LG TV Won’t Turn On
Understanding the common causes of the problem can be extremely helpful when it comes to LG TV troubleshooting.
Power supply issues are among the most common causes of a TV not turning on.
This can include faulty power cords or outlets and issues with the TV’s power board or power supply unit.
It’s important to check that the power cord is properly connected to power cable between the TV and the power outlet and that there are no exposed wires or damage to the cord.
If the power switch, cord and outlet are working properly, it’s time to troubleshoot the power board and power supply unit.
Another common cause of LG TVs not turning on is remote control problems. If the TV doesn’t respond when you press the power button on the remote, it’s possible that the batteries are dead or the remote control is faulty.
To troubleshoot this issue, you can test the batteries to make sure they’re properly inserted and have enough power.
If the batteries are low, replace them with fresh ones and see if that fixes the problem.
If the remote control still doesn’t work, try using a different remote or contact LG customer support for further assistance.
Lastly, faulty cables can also cause an LG TV not to turn on. This includes issues with HDMI cables, coaxial cables, and power cables.
If you suspect that a faulty cable is causing the issue, try swapping out the cable for a new one and see if that fixes the problem.
It’s also important to ensure that all cables are properly connected to the TV and any other devices, such as a cable box or gaming console.
Whether you’re a new LG TV owner or have had your smart TV for a while, our troubleshooting guide will help you get your TV up and running again in no time!
How To Check Power Cord and Power Outlet
If you’re experiencing issues with your LG TV not turning on, the first step is to check the power cord and power outlet. Here are some detailed steps you can follow:
Make sure the power cord is connected to both the TV and the power outlet. Check that the cord is securely plugged in and that there are no exposed wires or damage to the cord.
If the power cord is correctly connected, try plugging the TV into a different power outlet or power strip.
This can help determine if the issue is with the TV or the original power outlet.
If the TV turns on when plugged into a different wall outlet or power strip, then the original power outlet may be faulty. You should have an electrician check the outlet to ensure it’s working properly.
If the TV still doesn’t turn on after trying a different wall outlet, the issue could be with the extension cord or the TV’s power supply.
You may need to replace the cord or take the TV to a repair shop to diagnose and fix the issue.
By following these steps, you can quickly determine if the issue is with the power cord, wall outlet, or TV’s power supply.
This can save you time and money by helping you diagnose and fix the problem quickly.
Troubleshooting the Power Board and Power Supply
If you’ve checked the cord and power outlet and your LG TV still won’t turn on, it’s time to troubleshoot the power board and power supply:
Unplug the TV:Â Before you begin, unplug the TV from the power outlet and let it sit for a few minutes to discharge any residual power(to be on the safe side).
Check the power board:Â The multi box is responsible for regulating the voltage that goes into the TV. To check the board, you will need to remove the back cover of the TV.
Look for any visible signs of damage, such as burnt components or blown capacitors.
If you notice any damage, you will need to replace the power board. If the power board looks fine, move on to the next step.
Test the power supply:Â The PSU is responsible for converting AC power from the wall outlet into DC power that the TV can use.
You will need a multimeter to test the power supply.
Set the multimeter to DC voltage, touch the black probe to a ground point on the TV’s chassis, and touch the red probe to one of the PSU’s output pins.
Check the voltage reading against the values listed on the power supply label.
If the reading is lower than the value listed, your power supply is faulty and will need to be replaced as soon as possible.
Reassemble the TV:Â Once you have replaced the power board or power supply, reassemble the TV and plug it back in. Turn on the TV to see if it’s working properly.
By following these steps, you can troubleshoot the power board and power supply of your LG TV and determine if either component is causing the issue.
If you’re uncomfortable performing these steps yourself, taking your TV to a professional repair shop is best.
How to Test and Replace Remote Control Batteries
Remote control problems are another common cause of LG TVs not turning on. If the TV doesn’t respond when you press the power button on the remote, it’s possible that the batteries are dead or the remote is faulty.
To troubleshoot this issue, you can test the remote batteries to make sure they’re properly inserted and have enough power.
Replace remote batteries if they are low on power and if the remote control still doesn’t work, try using a different remote or contact LG customer service for further assistance.
Checking the Input Source and Correct Channel
Checking the Input Source and Correct Channel
Here’s a detailed guide on how to check the input source and correct channel on your LG TV:
Check the input source: The input source is the device that the TV is currently receiving a signal from.
Make sure the input source is connected to the TV and turned on. To change the input source, press the Input or Source button on your TV remote control.
Check the correct channel: Make sure the TV is set to the right channel if nothing appears on the screen.
The right channel may differ from set to set and service provider to service provider.

Check cable connections: If you’re still not seeing anything on the screen, check the cable connections between the TV and the device you’re trying to use.
Make sure the power cable is properly inserted and that there are no signs of damage. Also look if there is a faulty power outlet that is the cause.
Try a different device: If you’re still having trouble getting an image to appear on the TV, switching to a different device can help you determine if the problem is with the TV itself or the source device.
By following these steps, you can quickly check the input source and correct channel on your LG TV and get it up and running again.
Always check your cable connections and try a different device if you’re still experiencing issues.
