LG TV Apps Not Working
Apps Crashing, Loading, Or Refusing To Open
You press the Netflix button. Nothing. Or the app opens and crashes. Or every app you try refuses to load. Or the app store itself won’t open. The TV works fine otherwise, but the apps are unusable.
Here’s the thing most people get wrong: they assume the TV has failed and start looking for a replacement. In reality, app faults are almost always software or network issues, not hardware. And in the vast majority of cases, they’re fixed by checking the network, clearing a cache, or reinstalling the app.
Only when those are ruled out does the fault move to the Wi-Fi module or the main board. Even then, an external streaming device is often a cheaper and better solution than a repair.
This guide walks through the app chain in order, tells you how to isolate the fault, and shows you how to decide between repairing the TV and adding a streaming stick.
Why Your LG TV Apps Stop Working
LG TV apps run on webOS, and the app chain has several links. Any of them can fail:
-
Network connectivity fault — the most common cause. If the TV can’t reach the internet, no app will work.
-
Wi-Fi password change — if you’ve changed your Wi-Fi password and not updated the TV, every app will fail.
-
DNS fault — the TV may be connected but unable to resolve domain names. Switching to a public DNS often fixes it.
-
App cache corruption — cached data becomes corrupt over time, causing apps to fail or crash on launch.
-
App data corruption — beyond the cache, the app’s settings and login data can become corrupt.
-
webOS software fault — a firmware bug can break app functionality, often after an update.
-
Insufficient memory — too many background apps can crash the system.
-
App server outage — sometimes the fault is at the app’s end, not yours.
-
App deprecation — some apps are discontinued and stop working permanently.
-
Failed Wi-Fi module — if the module fails, the TV loses network connectivity.
-
Failed main board — in rare cases, a main board fault affects network processing.
Common Symptoms

-
Apps show a blank screen
-
Apps work intermittently
-
Apps fail after a firmware update
-
Apps fail after a network change
-
App store won’t load
-
Apps disappear from the home screen
-
Apps fail to update
What Causes These Faults
Network faults. The single most common category. Wi-Fi signal problems, router issues, and DNS faults all present as app failures. Check the TV’s internet connection first.
Cache and data corruption. Over time, apps accumulate cached data that can become corrupt. Clearing the cache or reinstalling the app resets this.
webOS software faults. Firmware bugs can break app functionality. These often appear after an update and are usually fixed by a subsequent update or a factory reset.
Memory issues. webOS TVs have limited RAM. Too many background apps can crash the system.
App server outages. Sometimes the fault is entirely at the app’s end. No amount of troubleshooting on your TV will fix a server outage.
Hardware faults. Wi-Fi module or main board failures are rare but possible. These are the last things to diagnose, not the first.

What You’ll Learn
You’ll learn how to confirm whether the fault is one app or every app, which splits the diagnosis immediately. You’ll learn how to test the TV’s network connection, how to change DNS settings, and how to diagnose a weak Wi-Fi signal.
You’ll learn how to clear app caches, reinstall apps, and reset individual app data. You’ll also learn how to safely perform a factory reset without losing the settings you want to keep.
You’ll also learn how to check for app server outages, how to diagnose a Wi-Fi module fault, and how to decide whether a hardware fault justifies a repair.
Repair or Bin?
Most LG TV app faults are free to fix. A network issue, a cache problem, or a software fault accounts for the overwhelming majority of cases. All are resolved through the TV’s menus without any hardware repair.
Where the maths changes is the Wi-Fi module or the main board. A Wi-Fi module is typically $30 to $70. A main board is $60 to $150. On a TV under five years old, both are worth repairing. On a TV over five years old, weigh the repair cost against the cost of a new set.
An alternative to repairing the internal Wi-Fi is to use a wired Ethernet connection or an external streaming device. For $30 to $100, a streaming stick gives you access to the same apps without relying on the TV’s hardware.
The guide includes a clear repair-or-replace threshold for each component, plus a section on the external streaming device alternative.
Frequently Asked Questions
Why have all my LG TV apps stopped working?
The most common cause is a network fault. Check the TV’s internet connection first. If the TV is connected but apps still fail, try changing the DNS settings.
Why does one app fail but others work?
This points to an app-specific fault, such as a corrupt cache or a server outage. Clear the app’s cache, reinstall it, and check the app’s status for outages.
Why do my LG TV apps crash on launch?
This is usually a memory or cache issue. Close background apps, clear the cache, or reinstall the app.
Why do my LG TV apps stop working after an update?
This is usually a software or compatibility fault introduced by the update. Check for a subsequent update, or perform a factory reset.
Is it worth repairing an LG TV with app problems?
Usually yes, and often it’s free. Most app faults are software or network issues, not hardware. If the Wi-Fi module or main board has failed, an external streaming device is often the better solution.
