Solution #4 Disconnect Any Speakers
When the Hitachi Ultravision TV no sound appears, maybe you’ve connected external speakers or home cinema systems that don’t work, and in turn, the sound will be lost.
For that solution, you should disengage any external third-party devices that support sound transfers and test your TV’s default audio output.
Since we don’t know what type of devices you have attached to your Hitachi TV, disconnect ALL cables except for the power adapter of your TV.
That would include any AUX cables, HDMI cables, AV (component) cables, etc…
Even if you’re using streaming sticks, consoles, or cable boxes, disengage them and test your TV’s default sound.
The easiest way to check your Hitachi Ultravision TV sound is to open an application or a platform that contains media and play something.
Tip: Keep all external devices unplugged until the end of the guide or until you’ve identified the true cause of the issue.

This will wipe out all recorded data, applications, and files stored on your Hitachi Ultravision TV along with all configured settings and features.
Hopefully, the audio problem will be fixed as a result of the factory reset.
Here’s how to factory reset your Hitachi Ultravision TV in easy steps:
- Grab your Hitachi Ultravision TV remote and press the home button.
- Navigate to the settings of the device.
- Choose the system and head to Advanced System Settings.
- From there, locate the Factory Reset tab and enter it.
