Hold the power button on the TV itself for 10 seconds, or unplug from the wall for 60 seconds. Smart TVs accumulate memory leaks just like computers. A full power cycle clears everything.

Run a speed test on another device. Smart TV apps need at least 5Mbps for SD streaming and 25Mbps for 4K. If your connection is slow, the apps will buffer or fail to load.

WiFi signal issues cause app loading failures. If your TV is near your router, use an ethernet cable for a guaranteed stable connection. This fixes many streaming issues instantly.

On Samsung: Settings > Apps > select the app > Clear Cache. On LG: Settings > Application Manager > select app > Clear Cache. On Roku or Fire TV, uninstall and reinstall the app.

Outdated apps crash on updated TV firmware. Go to your TV's app store and check for updates for the specific app. Enable automatic app updates in TV Settings.

Go to Settings > Support > Software Update > Check for Updates. TV manufacturers release firmware patches specifically to fix app compatibility issues.

If one specific app keeps crashing, uninstall it completely and reinstall fresh from the app store. This clears all corrupted data for that app.

If multiple apps fail after trying all else, a factory reset restores the TV to original state. Go to Settings > General > Reset. You'll need to re-setup the TV but it resolves deep system corruption.
