Are you having sound problems with your Panasonic TV? Whether it’s Panasonic Plasma, Viera, OLED, or 4K, the audio problem is common and can undoubtedly spoil your viewing experience.
I have faced this problem in the past and it isn’t a major hardware issue and can be resolved at home if you know how to go about it.
A power cycle, soft reset, Auto-leveling volume in the audio settings, or simply pressing the unmute button can sometimes restore your sound in an instant, but for some people, the source of the problem can be hard to locate.
That’s why I created this comprehensive guide in which you will understand why the sound on your Panasonic TV is not working and how you can fix the problem.
Furthermore, I have also covered situations where sound isn’t working on HDMI, Optical Out, and sometimes the picture displays normally, but with no sound.
What causes no sound on Panasonic Smart TVs?
There can be multiple reasons behind your Panasonic TV not playing audio, you can see the picture but can’t hear audio. Minor mistakes like TV on mute, HDMI issues, settings, etc, can cause this problem.
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.
How to fix a Panasonic TV with no sound?
To regain the sound on your Panasonic TV, follow the below steps one by one carefully, and you will then be able to identify what was causing it and how to prevent it in the future.
Make sure mute and volume are set correctly
It might seem silly, but usually, we will not notice the silly things, so before jumping to further solutions, check out the sound and mute settings.
It is possible that your Panasonic TV is set on mute accidentally. You can check this by clicking on the mute button on your remote control.
The volume on your TV should be turned up if it is not muted to ensure that it has not been set too low, which prevents you from hearing anything.
Note: Do not forget to check all the cables for external devices, their output and input sources, and the power source. Confirm the cables are correct and the power source for the external speakers is working.
Ensure the sound settings are correct
Whether you have a Panasonic Plasma, Viera, 4K, or OLED TV, the sound settings are similar, and there are plenty of tweaking options for particular situations, so check if these settings are correct.
Check they have been adjusted accordingly:
- First navigate to the settings section of your TV.
- After that select sound and it will open all available options.
Here you can change settings and configure them accordingly if they have been set up incorrectly. You can check out the complete Panasonic Audio settings for reference.
Switch Audio Output
If you are using an external speaker or have changed your input device, you may have configured your audio output incorrectly.
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.
- Navigate to the ‘Menu’ button.
- Select either ‘Audio’ or ‘Sound’.
- Select either ‘HDMI Input’, ‘TV Speaker Settings’, or ‘Audio Preferences’, depending on your external device.
Make sure the correct option is selected depending on whether you are using the built-in speaker or not.
Possibly, your Panasonic TVs audio system glitched, resulting in the audio not playing through your speakers.
Unplugging your TV will solve this issue, as doing a power cycle is equivalent to doing a soft reset.
- Turn off the television with the remote.
- Unplug it from its main power source.
- Before plugging it back in, wait a few minutes (5-10 minutes).
- After that, switch back on your TV
Play any video on your TV and check if the audio is coming back. If it is not, then proceed to the next step.
Note: When using a cable box, it is highly recommended to remove it completely and then plug it back in after a couple of minutes so that all connections are reset.
