How to resolve stuttering sound on your Panasonic Smart TV ?

If you are experiencing stuttering sound on your Panasonic Smart TV, here are some things you can try to fix the problem:

1. Inspect Input Device

At times, the fault doesn't lie with your TV, but instead can be attributed to the device sending pictures and sound to your TV.

• Try using a different device to your TV, such as a DVD or Blu-Ray player, and see if that works. When the issue is with the cable you are watching, this will probably resolve the problem, which would signal that it is the sending device that is causing the issue, not the TV.
• Attempt switching off your cable, DVD, or Blu-Ray player, and make a pause of a few seconds, then switch it back on, and make another try. 
• If a certain device functions properly (for example, your DVD or Blu-Ray player), but another does not (for example, your cable box), it is suggested to contact the provider of the device that is no longer functioning.
• If the issue is solved, you can then Exit Menu. To do this, simply press the 'Return' button, or wait 30 seconds for the menu to exit automatically.

2. Restart the TV to Perform a power reset

To do this:

• Push the Power button on either the unit or the remote to power off the television.
• Next, unplug it from the electric outlet and wait for 10 seconds.
• Afterwards, reconnect the unit to the power outlet then turn on the TV again with the Power button.

3. Check the audio cables

• Unplug all of the audio cables from your TV.
• Inspect the cables for any signs of damage, such as frayed wires or broken connectors.
• If you find any damaged cables, replace them with new ones.
• Once you have replaced the cables, plug them back into your TV and test the sound again.

4. Check the audio settings

• Using your TV remote, navigate to the audio settings menu.
• Make sure that the volume is not muted and that the audio output is set to the correct source.
• You may also want to try adjusting the audio settings, such as the bass and treble levels.

5. Update the TV's firmware

Panasonic regularly releases firmware updates that can fix bugs and improve performance.

To do this:

• Navigate to the System menu on your TV.
• Select System Update.
• If there is a firmware update available, follow the on-screen instructions to install it.

6. Keep your TV and external speakers away from sources of interference

Sources of interference can include: Microwaves, Power lines, Fluorescent lights, Cordless phones and Other electronic devices.

When these devices emit radio waves, they can interfere with the audio signal from the TV or speakers. To avoid this, keep your TV and speakers away from these devices.

Here are some specific tips:

• Do not place your TV next to a microwave oven.
• Do not place your speakers near power lines or fluorescent lights.
• If you are using a cordless phone, try to keep it away from your TV and speakers.
• If you have other electronic devices in the same room, try to keep them away from your TV and speakers as well.
• Radio waves can interfere with the audio signal, causing stuttering sound.
• The interference can be caused by the proximity of the devices or by the strength of the radio waves emitted by the devices.
• Keeping your TV and speakers away from sources of interference can help to prevent stuttering sound.

7. Make sure that your TV is properly ventilated

TVs have vents on the back and sides to allow heat to escape. If these vents are blocked, the TV can overheat, which can cause problems with the audio output. 

To make sure that your TV is properly ventilated, follow these tips:

• Do not place your TV in a confined space, such as a cabinet or built-in entertainment center.
• Leave at least 2 inches of space between the TV and the wall.
• Do not place objects on top of the TV.
• If you are using an external speaker, make sure that it is also properly ventilated.
• Overheating can damage the TV's components and shorten its lifespan.
• It can also cause the TV to malfunction, such as stuttering sound.
• Proper ventilation helps to keep the TV cool and running smoothly.

8. Reset the TV to factory settings

Resetting the TV to factory settings is a last resort, but it may fix the stuttering sound problem if all else fails. This will erase all of your TV's settings, so make sure to back up any important data before proceeding.

To reset your TV to factory settings, follow these steps:

• Turn on your TV.
• Using your TV remote, navigate to the System menu.
• Select Reset to Factory Defaults.
• A message will appear asking you to confirm the reset. Select Yes.
• The TV will restart and the factory settings will be restored.

Once the TV has been reset, test the sound again. If the stuttering sound is gone, then you have successfully fixed the problem.
