Ways to Fix Apps Issues on a Panasonic Smart TV

1. Restart the TV

This is the simplest and most common fix for many problems. 

To restart your TV:

• Push the "Power" button to turn off the Panasonic TV.
• Now, Unplug the power cable from the wall socket for 30 seconds.
• Reconnect the power cable and turn your TV back on.
• Check to see if the problem has been resolved.

2. Connect TV to Internet via Wi-Fi

If restarting the TV does not resolve the issue, then you have to Connect to Wi-Fi.

To begin:

• Utilize your remote to push the Menu button.
• Then, scroll using the down arrow until you see Network and tap OK. 
• Again press OK on the Network connection menu and select Quick Setup to start the connection process. 
• From this menu, designate your preferred connection and follow the on-screen instructions for a WPS connection. 
• Otherwise, opt your wireless network from the list and type in your wireless network password when prompted.
• Upon connecting, a confirmation screen will appear. You should Select Done to complete the connection to your wireless network.

3. Perform Software Update

If you are connected but still facing issues, you need to update the TV's Software.

To do this:

• Press the Menu button on the remote control. 
• Scroll down to Network and press OK. 
• Scroll down to Software update and press OK. 
• Press the OK button on the firmware information screen. 
• Choose Yes on this screen to have the TV look for new software. 
• Allow the TV to process updates. Refrain from using your TV remote until the progress bar reaches 100%. 
• The TV will subsequently reboot.
• Upon fully restarting your software update is done!

4. Enhance Wireless Network Connection

If you cannot connect the TV to your Internet, you can try to power cycle your Modem and router or moving the router closer to the TV.

To power cycling your modem and router:

• Unplug the power cables from your modem and router, ensuring that all lights have gone off on both devices. 
• After a minute, plug back in your modem and then your router.

If your signal strength is still fair or poor and you are having trouble connecting or experiencing playback issues, consider relocating your router to a different spot.

Position your router closer to your Smart TV or reduce the amount of obstructions and walls between them and the signal should become better. A marginal amount of feet or inches may produce a noticeable change.

Maybe try changing the location temporarily to check if the signal is the issue. Additionally, adjust the antennas if your router has them. 

Additionally, try placing the router higher up if possible. And if inside a cabinet,  Remove it to see if signal quality improves. 

If the wireless signal still isn't sufficient, here are a few further options:

• Obtain a new wireless router with a stronger signal and more stable software; remember to look at online reviews before making your purchase.
• Alternatively, you could explore more advanced home networking solutions, such as range extenders, mesh network routers, or power line extenders to expand your household's wireless coverage.

If the connection is still not successful, you can reach out to your ISP or Router manufacturer for technical support. 

5. Perform Factory Reset

Resetting your device to its original factory default levels eliminates all accounts as well as saved configurations. Do not switch off or disconnect the television while conducting a factory reset. 

To do this:

• Press Menu on the remote, then use the "arrow down" and "arrow up" to select Setup and press OK. 
• Navigate with the "arrow down" and "arrow up" to select System and press OK. 
• Select Factory Default with the "arrow down" and "arrow up" and press OK. 
• Finally, use the "arrow right" and "arrow left" to choose Yes and press OK. 
• The reset process will need a few minutes to finish. 
• After that, you can proceed with setup.
