Start with an app restart and an update; a factory reset should be the last step.
When an app returns to the TV home screen or refuses to open, the fault is not necessarily your internet speed. App crashes can be caused by device memory, software versions, corrupt temporary data or an unsupported application.
Try this first
Work through these checks in order. Stop once the problem is resolved.
- 1Close and reopen the affected app.
- 2Restart the television fully and check for available app and TV software updates.
- 3Check available device storage, then compare with another app.
- 4Reinstall only after confirming you can sign back in.
Begin with a proper restart
Close the app completely, then switch the television off and restart it using the manufacturer’s recommended method. Some TVs remain in standby when you use the remote, so a fuller restart may be needed. Check whether other installed apps work. If only one app fails, it is usually best to begin with that app rather than reset the entire TV.
Check app and system updates
Look for updates in the TV’s official app store and system settings. Apps may stop working on an older software build, and some services withdraw support from ageing TV models. Check the provider’s published compatibility requirements rather than relying on the presence of an old app icon.
Storage, cache and reinstalling
Low free storage can make apps unstable. Delete unused downloads and applications only if you know what they are. Some platforms offer a cache-clear option; others require uninstalling and reinstalling the application. Record any sign-in details first and avoid entering passwords into unofficial replacement apps.
When to contact support
If the app repeatedly fails after updates and a clean reinstall, note the TV model, software version, app version and the point at which it crashes. Support teams can work more effectively with an error message or a short description than with “it does not work”. A compatible external streaming device can sometimes extend an older TV’s usefulness.
Deleting application data may erase downloads and sign-ins, unlike a simple restart.
