LG TV Won’t Turn On But Red Light Is On

If your LG TV won’t turn on but the red light is on, it can be due to several reasons, and the reasons can be the same as the previous ones. However, to fix it, you need to turn on the TV by using the physical button on the TV instead of the remote control. Note that the location of the physical button varies depending on your TV model.

If it does not work for you, then follow the other steps mentioned below to resolve the issue.

How to Fix LG TV Won’t Turn On

After knowing the reasons for the issue, you might be wondering how you can fix it. Worry not, let’s look at possible fixes to the LG TV won’t turn on problem.

Check the Power Outlet

The first thing you need to do is check the power cable to see if your LG TV won’t turn on by plugging another device into the outlet.

If the other device does not work, the issue is related to the power outlet in which you are plugging the devices. On the other hand, if it works without any issues, then move on to the next fix.

Check the Power Cable

Another thing you need to do is check your LG TV’s power cable, as it might be the reason for the issue. Hence, make sure that the cable is entirely undamaged by examining the TV’s power cable for exposed wires or damage. If this is the issue, you need to replace the cable. If the power cable is intact, move on to the next fix.

Power Cycle Your LG TV

Another thing you can do if your LG TV won’t turn on is to power cycle it. Simply turning your television off and on again is what power cycling requires. Yet, unlike a simple on/off, you must drain the circuit of any leftover electrical charge throughout the operation to ensure that the system restarts perfectly. Here’s how you do it:

Step 1: Disconnect your LG TV from the wall outlet.

Step 2: After around 60 seconds, hold down the power button on your television for 30 seconds.

Step 3: Reconnect your LG TV to the power source, and it should start working.

Replace the Remote’s Batteries

As mentioned earlier, if the LG TV won’t turn on with the remote when the red light is on, it’s due to weak or low batteries in the remote control.

Hence, replace the batteries on your remote and try turning it on again, and it should start working without any issues.

Reset Your TV Remote

LG TV won’t turn on could also be caused by a problem with the remote. In a situation like this, simply drain the excess battery from the remote control by following these simple steps:

Step 1: Remove your TV remote’s batteries.

Step 2: Long-press the power button on the remote for around 30 seconds.

Step 3: Put the batteries back in after 30 seconds and check the TV for functionality.

Check the Input Source

If the source of input does not match the TV preset, the LG TV won’t turn on. Also, if this is the case, the power light may also blink. What you can do in such instances is as follows:

Step 1: Confirm that the input source is compatible with the LG TV. You won’t be able to see anything if you choose HDMI 1 as your input but connect the source to HDMI 2 power.

Step 2: If the power light is turned off, your LG TV may be on but is attempting to connect to the wrong source.

Step 3: You must be able to switch the source with your remote (if the Settings menu is visible or if the remote has a direct Source button). If you are unable to change the input due to a blank screen, try clicking the Home button on your remote control, which should exit any HDMI input.

Disconnect External Devices

Additional devices, like gaming consoles or soundbars, can sometimes cause problems with a television’s power supply. Restart your TV after disconnecting any external devices. If it boots up without any external devices plugged in, one of them could be the cause of the problem. Reconnect them one at a time until you locate the one causing the LG TV won’t turn on problem.

Check if the Backlight is Broken

If the backlight of your TV is broken, it might be the reason why your LG TV won’t turn on. Here’s what you can do to verify:

Step 1: Hold a flashlight near the screen. The backlight has failed if you notice a little image in the illuminated region.

Step 2: It might be a faulty power supply to the backlight, or it could be the backlight components themselves. Another indicator of a shorted backlight is a blinking standby light.

Contact LG Customer Support

If all else fails and your LG TV still won’t turn on, you need to contact LG customer support, as they can provide expert advice and, if necessary, make professional arrangements. Make sure you have your TV’s model number and warranty information handy when you contact them.
