You noticed your LG TV is lagging and apps are taking a long time to open or close. In most cases, restarting a TV can fix these issues. Restarting your LG TV can also help when WebOS struggles with an app or certain features.
However, restarting an LG TV is not as straightforward as you might think.
I know what you’re thinking:
Doesn’t the power button on your LG TV’s remote shut down the TV? In most cases, the power button doesn’t completely turn off the TV. Instead, it puts the TV into standby mode. And when you press it again to turn on the TV, what really happens is you’re waking the TV up from standby mode.
There are a couple of reasons for that. For starters, waking the TV from standby mode is much faster than booting it from scratch. It skips the boot sequence. Secondly, most TVs will run through pixel refresh processes when in standby mode that help keep the panel fresh.
So rebooting a TV with the remote is not possible, even though that’s the most logical action to take. There’s another way to reboot your TV that can refresh the apps and operating system.
There are a few different ways to restart an LG TV from scratch.
How to Restart LG TV Web OS:
In some cases, the LG TV Web OS will not restart, even when you do a full power cycle. Web OS can sometimes run into bugs or issues that will make it lag and stutter. If you’re experiencing those issues, rebooting Web OS is a good idea, especially if it’s frozen. It’s very easy.
To restart the operating system on an LG TV, hold down the volume down button and power key for 12 seconds. You should see an LG logo boot sequence on the display. If the TV started with no logos, you might need to hold down the buttons for longer.
How to Restart an LG TV with a Remote:
- Press the settings button on your remote
- Navigate to General.
- Select User Agreements.
- Your LG TV will ask you to restart the device.
- Waiting for the LG TV to restart. It will perform a complete reboot.
- Continue using your LG TV.
Unfortunately, LG TVs do not have a restart or reboot option in the menus. However, you can do a fresh reboot with the above method by using your remote, from the comfort of your couch. This method should also reboot the operating system.
Here’s the thing:
If your remote is having issues, or the restart didn’t improve the performance on your TV, the next step is to do a power cycle.
It’s very straightforward.
Disable Quick Start+
Another way to restart an LG TV is to disable QuickStart. Not every TV will have this feature, but it’s worth checking the settings. When disabled, the TV will complete the entire boot sequence from scratch every time the TV is turned on.
As you might have guessed, it will take longer for the TV to start with QuickStart disabled. However it can solve performance issues, and you can always toggle it back on later.
How to disable QuickStart on an LG TV:
- Press the Settings button on your remote
- Browse to General
- You should see an option called QuickStart + and disable it
When a firmware update is available for your LG TV, it will automatically install and your TV will performance a fresh reboot.
To check for firmware updates, press the Settings button on your remote, open All Settings, and select General. Scroll down until you find an option labelled About This TV.
Select the Check for Updates button. If an update is available, it will automatically download (internet connection required) and install with a reboot required. It’s always a good idea to check for firmware updates, as many of them fix issues.
How to Restart an LG TV without a Remote:
If the above options did not fix your LG TV’s issue, the next best thing is to try a power cycle. Don’t worry, it’s not as complicated as it implies.
A power cycle will not only reboot a TV but also drain any excess electricity, which can fix a number of issues, such as the LG black screen problem.
How to power cycle an LG TV:
- Unplug it from the main outlet.
- Hold down the physical power button on the TV for 60 seconds.
- Plug it back in and turn it on.
In most cases, a power cycle and a fresh reboot will fix the performance issues with your LG TV. Of course, as a TV ages and components start to reach their end-of-life, these tricks will no longer work. It won’t help to constantly power cycle an old TV.
How Do You Know When LG TV Booted Normally?
You should see a WebOS logo and an animation sequence when starting an LG TV for the first time. If you don’t see any logos, chances are your TV is simply waking from standby mode.
In which case, you’ll need to use one of the options above to restart WebOS from scratch. In most cases, an LG TV will always run through the full boot sequence when you reconnect it to a power outlet.
The Bottom Line:
To summarize, the easiest way to force an LG TV to restart is to unplug the power cord and hold down the power button for 30 seconds. A forced shut down like this one will reset all the TV’s system apps which stop your TV from lagging as it did before.
