Why Does My Hisense TV Have No Sound?

Several things might cause the “no TV sound” problem on your Hisense TV.

If you can get a handle on these variables, you can more easily pinpoint the problem and implement a workable solution:

  • Muted or low volume settings: There may be no sound if the mute button is accidentally pressed or the volume is too low.
  • Sound mode settings: Hisense TVs provide audio settings for various programs. The quality of the sound may suffer if the wrong mode is used.
  • Audio output settings: Even if you plan to utilize the TV’s built-in speakers, your Hisense TV may be set up to send sound via an external device like a soundbar. If the settings are incorrect, there may be no sound.
  • Damaged or improperly connected cables: You may experience a disruption in the audio signal between your TV and connected devices if the wires are damaged or the connections are not secure.
  • Internal speaker problems: It is possible that your TV’s internal speakers need to be fixed or are being blocked by anything.

5. Utilizing External Audio Devices

Utilizing External Audio Devices

External audio devices, such as soundbars or home theater systems, can significantly enhance your TV’s audio quality and bypass potential issues with internal speakers.

With the correct cables or wireless connections, link an external audio device to your Hisense TV. (For information on how to set up the connection between your TV and audio device, please see the respective user manuals.)

You can access the TV’s audio output or sound settings by following these steps:

  1. Go to the Menu.

Evaluating the sound and TV-watching experience is the next step after connecting an external audio device. Adding an external audio device to your home entertainment system may significantly improve the quality of the overall experience.

6. Switch the Digital Output Format to PCM

The digital audio output setup in the Hisense TV’s sound settings is another typical cause of no sound.

Changing the audio output format to PCM (Pulse-Code Modulation) should resolve the problem. See below for instructions on how to do that:

Switch the Digital Output Format to PCM
  1. Turn on your Hisense TV and go to the Main Menu.
  2. Go to Device Preferences.
  3. Go to Sound.

To ensure you won’t face audio issues again, follow these rules.

Proper TV Placement

If your TV is experiencing audio problems, try mounting it to the wall or placing it on a flat, firm surface. Keep a safe distance from the TV and other devices that might interfere with the signal or distort the sound.

Proper TV Placement

Don’t put anything in front of, behind, or on top of the TV since this might cause the screen to become too hot and interfere with the sound.

Optimal Audio Settings

Check your Hisense TV’s audio settings. The equalizer, sound mode, and the ability to turn various audio improvements on or off are all possible methods.

Ensure the TV’s firmware has been protected over time by installing security updates and patches, as well as updating the firmware to the latest version provided by the manufacturer, which might lead to incompatibilities with external devices and shaky audio.

Ensure your sound system is set up correctly and compatible with the Hisense TV if you use external speakers or a soundbar.

Check the manufacturer’s requirements to avoid incompatibilities and get the most out of your audio gear.

Routine Maintenance Tasks

Maintaining a clean TV and its parts, especially the vents and speaker grilles, is essential. (A device’s sound quality and temperature might be negatively affected by dust or particle accumulation.)

Routine Maintenance Tasks

Firmly plug in all the cables and free of damage and corrosion by performing routine inspections. Be sure to switch out frayed wires.

If your Hisense TV’s sound quality is consistently poor, it may be a software issue that may be fixed by doing a factory reset.

Protecting Against Power Surges and Electrical Issues

Use a surge protector for your TV and any associated audio equipment.

Avoid putting the TV and audio equipment into already overburdened sockets to reduce the likelihood of electrical problems or interference.

Protecting Against Power Surges and Electrical Issues

If there is a power outage, disconnect the television and any other electronic devices that sudden voltage changes might damage.

The likelihood of encountering audio problems with your Hisense TV may be reduced according to these preventative actions and maintenance suggestions, resulting in consistently high-quality sound throughout time.
