Open Settings, remove or clear the app if possible, or uninstall and reinstall via LG Content Store.
I have worked with many LG TVs and helped people fix app crashes, freezes, and login problems. This guide shows practical, tested steps for how to reset apps on LG TV. I explain simple app-level resets, when to uninstall and reinstall, and when a full TV reset is needed. You will get clear steps, troubleshooting tips, and real-world advice so you can fix app issues fast.
Why you might need to reset apps on LG TV
Apps can slow down, crash, or stop signing you in. This happens with streaming apps, games, and utility apps. Resetting an app often fixes glitches without touching your other settings. Knowing how to reset apps on LG TV saves time and avoids a full factory reset.
Common causes for app problems
- App cache or temp files that grow too large.
- Corrupted updates or failed installs.
- Account or sign-in errors inside the app.
- Network or software version mismatches.
When to reset an app versus the whole TV
- Reset the app when only one app misbehaves.
- Uninstall and reinstall the app if resetting fails.
- Use a full TV factory reset only when many apps or system features fail.
How to reset a single app on LG TV: step-by-step
These steps work on most webOS LG TVs. Exact menu names can vary a little by model and webOS version. Follow them in order. If a step is not available, move to the next recommended action.
Restart the TV first
Turn the TV off, unplug it from power, wait 30 seconds, and plug it back in.
Power cycling often clears small app errors and is fast to try.
Close and reopen the app
Press the Home or Back button to exit the app.
Reopen the app from your launcher to see if the issue is gone.
Sign out and sign back in
Open the app, go to its account or settings area, and sign out.
Sign back in using your credentials. This fixes many playback or license issues.
Remove and reinstall the app
From the Home launcher, highlight the app icon.
Press and hold the OK or Enter button until options show, then choose Remove or Delete.
Open the LG Content Store, find the app, and reinstall it.
Reinstalling removes app data and gives you a clean start.
Clear app cache or data (if available)
Some apps offer a clear cache option inside their settings screen.
If you see Clear Data or Reset App inside the app’s settings, use it to wipe local data.
Notes about app-level reset
- Many LG webOS versions do not offer a global “clear cache” for apps. Uninstalling is often the most reliable reset.
- Keep your login info handy. Reinstalling may require signing in again.
How to reset all apps or perform a TV factory reset
A full TV reset removes all installed apps and returns the TV to default settings. Use this only when multiple apps fail, the system is unstable, or other fixes fail.
Steps to factory reset most LG TVs
- Go to Settings or All Settings from the home screen.
- Choose General.
- Select Reset to Initial Settings or Reset & Admin depending on model.
- Confirm the reset. You may need your TV password or the default PIN (often 0000).
- Set up the TV again and reinstall apps from the LG Content Store.
What a factory reset does
- Removes all installed apps and their data.
- Restores default settings for picture, sound, network, and system.
- Keeps the TV’s firmware version but clears user data.
When to avoid a factory reset
- If only one app is failing. Try uninstall or sign-out first.
- If you rely on many custom settings and profiles you’d rather not rebuild.
Troubleshooting tips and best practices
Use simple routines to prevent app problems. These tips helped me avoid repeat issues across multiple LG TVs I maintain.
Keep software and apps updated
- Check for TV firmware updates in Settings > General > About This TV.
- Update apps from the LG Content Store regularly.
Check your network
- Test the internet in Settings or by running another streaming app.
- Restart the router and use Ethernet for a stable connection.
Free up storage and avoid many small issues
- Remove apps you do not use.
- Reinstall apps periodically if they act up.
Use account and privacy steps
- Revoke device authorizations from the service provider if sign-in fails.
- Use two-factor authentication only when supported by the app.
When to contact support
- If apps still fail after reinstall and factory reset, contact LG support or the app developer.
- Keep logs: note app version, webOS version, and the exact error message.
Real-life experience, mistakes to avoid, and practical tips
I once helped a neighbor whose streaming app kept freezing every 10 minutes. We tried updates and restarts. The fast fix was uninstalling and reinstalling the app. A factory reset was unnecessary.
Lessons learned
- Always try a restart first. It fixes many issues.
- Uninstalling is safer than a factory reset.
- Keep your credentials and subscription info handy before reinstalling apps.
Common mistakes
- Doing a factory reset too soon. This costs time.
- Forgetting to update the app after reinstalling.
- Not checking network quality, which is often the real issue.
Quick practical checklist
- Restart TV and router.
- Close the app and sign out.
- Uninstall and reinstall.
- Update TV firmware.
- Factory reset only as last resort.
