A stuttering picture on a Panasonic Smart TV can be caused by a number of factors, including:

• A weak or unstable internet connection
• A faulty HDMI cable
• A problem with the TV's firmware
• A setting on the TV that is not configured correctly

This guide by Fixwebnode will cover how to resolve Stuttering picture problem on your Panasonic Smart TV.

Steps to fix Stuttering Picture Issues in Panasonic Smart TV

1. Check Input Device Status

Often, the issue is not with the TV, but with the device sending pictures and sounds to your TV.

• Attempt using a different device first. If you're watching cable, transition to a DVD or Blu-Ray and attempt playing something. If successful, it's likely the issue does not reside with your TV, but with the source of the program you are watching.
• Unplug your cable, DVD, or Blu-Ray player, wait a few moments, then plug it back in, and try again.
• If one device is functional (i.e. your DVD or Blu-Ray player), however the other is not (i.e. your cable box), it would be prudent to get in contact with the supplier of the malfunctioning device.

2.  Restart the TV

To do this:

• Press the Power button either on the unit or on the remote to turn it off. 
• Unplug it from the power outlet and wait for 10 seconds. 
• After the 10 seconds, plug it back in.
• Then use the Power button to turn the TV back on.

3. Check your internet connection

• Go to a website that offers speed test, such as speedtest.net or fast.com.
• Run the speed test and record the results.
• If the results are below the minimum requirements for streaming or gaming, try restarting your router or modem.
• If the problem persists, contact your internet service provider for assistance.

4. Check your HDMI cable

• Disconnect the HDMI cable from the TV and the source device.
• Inspect the cable for any damage.
• If the cable is damaged, replace it with a new one.
• Reconnect the HDMI cable and test the TV again.

5. Update the TV's firmware

• Go to the TV's Settings menu and select System.
• Select Check for Updates.
• If there is an update available, follow the on-screen instructions to install it.

6. Reset the TV's picture settings

• Go to the TV's Settings menu and select Picture.
• Select Reset Picture.
• Follow the on-screen instructions to reset the picture settings.

7. Avoid using power strips or surge protectors with your TV

• Power strips and surge protectors can sometimes interfere with the TV's signal.
• If you must use a power strip or surge protector, make sure it is a high-quality one that is designed for use with TVs.

8. Keep the TV away from sources of interference, such as microwaves and fluorescent lights

• Microwaves and fluorescent lights can emit electromagnetic waves that can interfere with the TV's signal.
• Keep the TV at least 6 feet away from these appliances and lights.

9. Disconnect any unnecessary devices from the TV's HDMI ports

• When you are not using a device, disconnect it from the TV's HDMI port.
• This will help to reduce the amount of clutter around the TV and prevent any unnecessary interference.

10. Clean the TV's HDMI ports with a soft, dry cloth

• Dust and dirt can build up in the TV's HDMI ports and cause signal interference.
• Use a soft, dry cloth to clean the ports once a month.
