6 Things To Do When Your LG TV Won’t Turn Off

There are a lot of frustration surrounding TVs when they don’t work, but one of the worst is when the TV won’t turn off at all.

The LG TV not turning off problem can be related to SIMPLINK settings or the batteries in the remote being dead. It’s also possible that there’s a hardware issue that needs addressing.

Problems with your TV are frustrating, but thankfully, this helpful article will walk you through all you need to know to fix an LG not turning off.

Why This Happens

There are several reasons an LG TV won’t turn off, but the main cause is usually down to either the remote or the TV being unresponsive to commands.

If there’s no signal from the remote, then it can’t tell the TV to turn off.

Similarly, if the TV isn’t responsive when given the signal to turn off, then you could be left with this frustrating issue.

How To Fix This Issue

Now let’s get to the most important part, the troubleshooting.

1. Start by Checking Your Batteries

The first thing you should do when you notice your TV isn’t turning off is to check whether the remote is working.

Try turning off the TV directly from the console.

If it works, then it’s quite likely that your remote batteries need changing.

Some remotes also flash or blink when you press a button, so if there’s no visual indicator in the form of a blink on the remote, then the batteries might be dead, meaning that your remote isn’t sending a signal to the television.

You should also make sure you’ve got the right type of batteries and that they’re properly installed.

Check whether your remote takes AA or AAA batteries before putting new ones in.


Another problem that can occur, forcing the TV to stay on, is if you’ve got it connected to any of your other smart devices.

If you do, then the screen might freeze or malfunction if a SIMPLINK feature is enabled.

To deactivate it, just follow these simple steps:

  1. Tap the Home button on your LG remote.
  2. Choose Settings from the menu and go to General.
  3. Choose SIMPLINK Options.
  4. Set the Auto Power Sync mode to the Off position, and you should be all set!

Doing this may fix some common issues with the SIMPLINK, allowing you to get back to business as usual.

3. Power Cycling

If the issue isn’t with your other devices or batteries, then it’s quite likely that your TV just needs power cycling.

Power cycling is a fancy term for turning your TV off and on again, allowing the system to flush out any corrupted code and start afresh.

  • Turn off the TV and unplug it from the wall.
  • Wait several minutes before plugging it back in to see if the issue is resolved.

If so, then you can rest assured that the visual glitch was just a bug that should have worked itself out.

4. Deleting Your Cache

If your cache is overloaded, then your TV might freeze and be unresponsive when you try to shut it down.

This can occur while streaming and is a common LG problem.

To clear your cache, follow these steps:

  1. Open the Settings menu.
  2. Navigate to User Menu.
  3. Disable your Quick Start Plus and SIMPLINK setup.
  4. Unplug your unit from the wall, wait several minutes, then plug it back in.
  5. Return to the home screen.

And that’s the simple way to clear your cache!

It’s a generally good idea to close out any apps you’re streaming from once you’re done so that you don’t freeze up your television.

5. Perform Any Updates Needed

Sometimes, the problem is as simple as needing an update.

Updates are intended to address bugs, add new features, and improve the stability of the system. As a result, you always want to stay on top of the latest updates.

In addition, updating can sometimes clear out bugs in the system, since updates often do a hard reboot when they load up for the first time.

6. Check for Interference

Sometimes, the issue is as simple as something blocking your sensors.

If a signal isn’t getting to the TV, then it’s not going to respond to any inputs.

Remove any obstacles from the TV and remote and try turning it off again.


Final Thoughts

There are a number of problems that can cause LG TV not to turn off.

Most of the time, you can rectify this problem by replacing the batteries in your remote, but on occasion, you’ll have to fiddle around with some settings or do any firmware updates required.

Make sure to disable the feature called SIMPLINK and power cycle your TV by unplugging it from the wall for 1 minute.

If the issue still persists after troubleshooting yourself, you may need to call LG to have one of their repair technicians take a look at it.
