Welcome to our guide on sound issues with your Panasonic TV. Are you experiencing a lack of sound on your Panasonic TV?

Don’t worry, in this article, we will explain how to quickly and easily troubleshoot any sound-related problems on your Panasonic TV.

Here’s what to do if the sound on your Panasonic TV is not working:

1. Restart Your Panasonic TV

Restarting your equipment can often resolve unexplained issues and reset the system.

For sound problems with a Panasonic TV, it is recommended to perform a power restart.

To do this, unplug your TV from the power outlet for 30 seconds, then plug it back in and turn it on again.

This will turn off the TV, and it will automatically turn back on.

2. Check if Your TV is in Mute Mode

Mute mode, also known as Hotel or Hospital mode, is a feature that significantly limits the volume of the TV, typically used in public places.

To exit this mode on a Panasonic TV, there are several methods depending on your TV model. Here’s the first method:

  • Turn on your TV.
  • Press the “Menu” button on your remote control.
  • Select the picture settings.
  • Highlight the “Contrast” line but do not confirm.
  • Enter the key sequence “6405” to access the hotel mode settings.
  • Select “No” on the first line using the “OK” button on your remote control.

If this method doesn’t work, you can also try holding the “Volume -” button on the side of your TV while pressing the “AV” button on your remote control three times. This should bring up the hotel mode menu on your screen.

Then, press the Menu button on the remote control, select “Hotel Mode,” and choose “No.”

You should now have normal sound levels.

2. Check Your HDMI Cables

If you have no sound on your Panasonic TV, the issue may be with your HDMI cable(s).

Start by checking if any cable has come loose on either end.

Also, ensure that your cable is not bent too tightly, forming a sharp bend, or stripped. The cable should remain rigid and straight as much as possible.

Lastly, if you have another cable available, try using it to confirm if the issue is with the cable.

Note: If you need to purchase a new cable, pay attention to the markings on the packaging. You will need an HDMI 2.1 cable to match the performance of current TVs (4K, etc.).

3. Check the Power Cord

No sound on your Panasonic TV? Could it be the power cord?

While it is a cable that is rarely manipulated, it can still become damaged, bent, or crushed by furniture, for example. The anomaly may be significant enough to partially affect the TV’s functionality without completely cutting off power.

Check if your power cord, or the cord of your sound system if connected to your Panasonic TV, is damaged. If in doubt, consider replacing it.

4. Check the Sound Settings on Your Panasonic TV

If you have no sound, several settings could explain the situation:

  • The sound is set to 0. Simply adjust the volume to a higher level.
  • The TV is on mute. Press the Mute button on the remote control again.
  • If you are using a soundbar, make sure to activate the ARC (Audio Return Channel) mode. Here’s what to do:
  1. Connect the soundbar to the HDMI ARC (HDMI 2) port.
  2. Go to the Setup menu > CEC Setup and enable CEC.
  3. In the Home menu > CEC, pair the soundbar with the TV.

Finally, disable Dolby Digital on your Panasonic TV by following these steps:

  • Press the “Menu” button on your remote control.
  • Select “Sound Settings” > “Digital Audio Output” and choose “HDMI” or “Optical” depending on how your external device is connected.
  • Select “Dolby Digital” and choose “Off” to disable Dolby Digital.
  • Press the “OK” button on your remote control to save the changes.

5. Update Your Panasonic TV

Updating your TV is often a way to eliminate various small electronic bugs that hinder the proper functioning of your TV, such as the lack of sound. Panasonic TVs have two methods for updating, depending on the TV type.

Update via USB

Follow these steps to update your TV using a USB drive:

  • Insert the USB drive into your computer. Format it to FAT32 (right-click and select “Format”).
  • Open your web browser and go to the Panasonic homepage (link provided in the Sources section below).
  • Look for the model number of your TV (located on a label on the back of your TV).
  • Check the current software version on your TV and only update the software if the version mentioned on the website is higher than the software version installed on your TV. Then, download and extract the software file.
  • Turn off the TV and insert the USB drive into your TV.
  • Turn on the TV. The software update screen will appear on your TV.
  • Follow the on-screen instructions and remove the USB drive.

The software update is now complete!

Update via Internet

To update the TV software via the internet, go to the menu and follow this path: Settings > All Settings > Software Update > Check for Updates > Internet > Start > Accept > OK.

The software update process will begin and takes between 5 to 15 minutes. The message “Installing System Update” will appear. Once the TV is fully loaded, turn it off and then turn it back on.

Your TV software is now up to date.

6. Reset Your Panasonic TV

Resetting a Panasonic TV is quite simple. Follow these steps:

  • Go to the TV menu using the remote control.
  • Follow this path: Setup > Factory Settings.
  • Confirm the reset, and it will automatically start.

7. Use Your Warranty

Despite all our advice, if you still have no sound on your Panasonic TV, it means you need to activate the warranty to resolve the issue.

A product purchased less than 2 years ago should be covered by the seller under the legal warranty of conformity.

Several solutions are possible, such as the intervention of a repair technician, an exchange, or contacting the manufacturer’s technician.

If your TV is no longer under warranty, you will need to call a specialized audio/video repair service at your expense.

To Summarize

Sound problems often have unknown origins, but they can be resolved with simple steps such as restarting your TV, checking the connections (power and HDMI cable), or performing a software update.
