Is your LG TV freezing, lagging, or not responding to apps? Rebooting the device can quickly resolve most software glitches. A proper restart can refresh the operating system, clear temporary bugs, and improve performance without affecting your settings. This guide walks you through the best methods to reboot your LG TV, including manual and remote options, plus troubleshooting tips.
Understanding the Reboot Process
Why Rebooting Helps
Rebooting an LG TV clears temporary system memory, stops background processes, and gives the software a fresh start. It’s a safe, quick way to fix app crashes, sluggish menus, or frozen screens—without erasing your saved settings.
When Should You Reboot?
- Apps not opening or crashing
- Remote control not responding
- TV stuck on black screen
- Menu or settings lagging
- After a firmware update
- Problems with Wi-Fi or HDMI detection
How to Reboot LG TV (Standard Methods)
Manual Power Cycle
The simplest and most reliable way to reboot your LG TV is by power cycling.
- Turn off the TV using the remote or power button
- Unplug the TV’s power cord from the wall outlet
- Wait 60 seconds to allow system memory to clear
- Plug the power cord back in
- Turn on the TV and check for improved performance
This basic reboot works well for freezing or minor performance issues.
Soft Reboot via Remote
Some LG models allow you to do a soft reboot using just the remote control.
- Hold the Volume Down and Power buttons on the remote together
- Keep holding for about 10 seconds until the LG logo appears
- The TV will restart without unplugging
This method is handy when your TV screen is frozen but still receiving remote signals.
Reboot Through TV Settings Menu
Use the LG WebOS Settings
If your TV is responsive, you can reboot it directly from the settings.
- Press the Settings button on your LG remote
- Scroll to All Settings
- Select General
- Tap Reset to Initial Settings (for factory reset) or use the Reboot TV option if available
Note: The Reboot TV option may only appear on newer models or with software updates. If not visible, perform a manual power cycle instead.
Advanced Reboot Options
Reboot via LG ThinQ App
You can control and restart your LG Smart TV remotely using the LG ThinQ app.
- Open the LG ThinQ app on your smartphone
- Ensure your TV is connected and added in the app
- Tap on your TV model from the device list
- Navigate to Settings or Power options
- Tap Restart TV (if the feature is supported on your model)
This remote restart is great for when you’re away from the TV or using your phone as the main controller.
Reboot with Quick Access Shortcut
On some LG TVs, you can set a Quick Access shortcut for rebooting.
- Press and hold a number key (e.g., 1–8) for a few seconds
- Assign Settings or Restart TV to the shortcut
- Next time, just hold that number key to access reboot functions
Not all models support this, but it’s worth checking in your quick access menu.
Troubleshooting: When Rebooting Doesn’t Work
TV Doesn’t Power On
- Check the power outlet and cable connection
- Try plugging the TV into a different wall socket
- Hold the Power button on the TV (not the remote) for 10 seconds
- If there’s still no response, check the surge protector or contact LG support
Screen Frozen Even After Restart
- Remove external devices like USB drives or HDMI cables
- Reboot again using the manual power cycle
- If the issue continues, check for software updates or try a factory reset
TV Keeps Restarting (Boot Loop)
If your LG TV is stuck in a continuous reboot loop:
- Unplug the TV for at least 5 minutes
- Remove any external storage devices or HDMI-connected devices
- Reconnect directly to the wall socket (avoid using power strips)
- If the problem persists, it may indicate a deeper software or hardware issue—contact LG support
Reset vs. Reboot: Know the Difference
Reboot
- Restarts the TV system
- Keeps your apps, Wi-Fi, and settings
- Best for temporary lags and app glitches
Reset

- Used for major bugs, selling your TV, or starting fresh
How to Factory Reset Your LG TV
- Press Settings > All Settings
- Navigate to General
- Select Reset to Initial Settings

Only reset when necessary. You’ll need to reconfigure your TV afterward, including apps, Wi-Fi, and login info.
Tips to Keep Your LG TV Running Smoothly

Too many background apps can slow the system. Keep only the ones you use regularly.

Reboot your TV once every 1–2 weeks to prevent memory buildup and system lag.
