Check Audio Settings: Verify that the TV's audio settings are configured correctly. Ensure that the volume is turned up, mute is not activated, and the audio output is set to the appropriate source.
External Speaker Test: If possible, connect external speakers or headphones to the TV to determine if the issue is with the TV's internal speakers. If sound works with external devices, it could indicate a problem with the TV's speakers.
