The following are some common reasons why Panasonic TVs do not have audio

Reason 1. Audio output setting is incorrect

If the output setting is set to a device that is not connected, the sound won’t play through. And you also won’t get audio on your soundbar, speakers, or external optical output devices.

So, It is possible your Panasonic TV’s audio output settings are incorrect, which is causing this issue.

Moreover, It does not matter if you are using the internal speaker of the TV, an external speaker, or headphones, if these are not correctly configured the issue won’t be solved.

Reason 2. Loose connections

Another common cause for no sound on Panasonic TVs is if you have external devices connected to the TV, the cables may not be properly connected, or if they are malfunctioning due to debris in the ports.

Reason 3. Internal hardware issues

Even though this is a rare occurrence, it can’t be ruled out and your Panasonic TV may have had internal speaker damage, or a piece of hardware may have malfunctioned, affecting the sound.

Reason 4. Sound settings are set too low

It may also be due to the sound settings. If these settings are too low, your audio may not play correctly on your television.

It is especially useful for those experiencing audio issues when using HDMI or Optical out devices. There are numerous users who report no issues with their TVs connected through HDMI or using external optical out devices like soundbars or speakers.

If you have an external speaker connected, ensure the HDMI cable is connected correctly.

  2. Select either ‘Audio’ or ‘Sound’.
  3. Select either ‘HDMI Input’, ‘TV Speaker Settings’, or ‘Audio Preferences’, depending on your external device.
