  2. Check and Reconnect Your Internet Connection

  3. Test Network Speed and DNS Settings

When to Call a Professional

If you have completed all steps including the factory reset and error code 9002 still appears, the issue may be caused by a failed internal motherboard component or a hardware fault affecting the TV's network module. At this point, contact LG Support at 1-800-243-0000 or visit LG's support website to check if your TV is still under warranty. A certified LG technician can run deeper diagnostics and replace internal components if needed. Also contact a professional if your TV becomes unresponsive or shows additional error codes after attempting these fixes.

In most cases, no. Error code 9002 affects voice recognition and AI features, but you can still watch regular TV channels, streaming apps, and use the remote normally. The error is a medium-severity issue that impacts smart features rather than core viewing functionality.
Why does LG TV error 9002 keep coming back after a restart?
If error 9002 keeps returning after a restart, it is likely due to a persistent network connectivity problem, an outdated firmware version, or corrupted Smart Hub data. Try updating the firmware, changing your DNS settings to 8.8.8.8, or resetting the Smart Hub to prevent the error from recurring.
Does LG TV error code 9002 mean my TV needs to be replaced?
