Most problems with your Panasonic TV are solved by performing a firmware update, hard reset or factory reset. You can also check the remote or power supply if it won’t turn on, or the TV’s input cables or settings if there is no sound or picture. Otherwise, it may be broken or faulty hardware.

If your Panasonic TV is not working, there are a number of troubleshooting tips that can help in most situations. These include a hard reset, firmware update or factory reset. You can find how to perform these below.

Hard Reset

A hard reset will drain all power from your TV, allowing it to dump any malfunctioning or unnecessary memory. This will not make any changes to your saved preferences or your downloaded content, so it is always worth trying.

Step 1: Turn off your TV and any connected devices.

Step 2: Unplug your TV from its power outlet.

Step 3: Press and hold the power button on the back of the TV from 30 seconds.

Step 4: Leave the TV unplugged for another 10 minutes.

Step 5: Plug your TV back in and turn it back on.

Firmware update

A firmware update will be released in response to any bugs in the previous version of the firmware. If you keep your TV up to date, firmware bugs should be resolved quickly.

Step 1: Press the ‘Menu’ button on your remote.

Step 2: Under ‘Network’, select ‘Software Update’.

Step 3: If a new update is available, select the newest version of the software and select ‘Yes’ to confirm the update.

Factory Reset

Performing a factory reset is guaranteed to fix any issues relating to your TV’s software or settings. This will erase all saved preferences, downloaded content and firmware updates. If a factory reset does not fix the issue, you know that it is a hardware problem or an issue with an external device or cable.

Step 1: Press the ‘Menu’ button on your remote.

Step 2: Navigate to Setup > System > Factory Defaults

Step 3: Select ‘Yes’ to confirm a factory reset.

If your Panasonic TV won’t turn on, you may need to reset it to its factory settings. Here’s how to reset your Panasonic TV:

  1. Unplug your TV from the power outlet.
  2. Press and hold the power button on the TV for 30 seconds.
  3. Release the power button.
  4. Plug the TV back in and turn it on.
  5. If your TV still doesn’t turn on, try pressing the “Menu” button on your TV’s remote control. If the menu appears, the problem may be with your TV’s input source or cable connection.
  6. If the menu doesn’t appear, try pressing the “Volume Down” button on the TV itself. If the volume bar appears on the screen, the problem may be with your TV’s remote control.
  7. If none of these solutions work, you may need to contact Panasonic customer support for further assistance.

Note that resetting your Panasonic TV will erase all settings and data, so make sure to back up any important information beforehand.

Panasonic TV Has No Sound

The first thing to check when your sound is not working on a Panasonic TV is that the volume is turned up and you do not have the TV on mute. This applies for both the TV and any external speakers. If you have checked these simple things, run through each of the possible causes below.

Device Connections and Settings

You will know if it is a specific device causing the issue if other input channels still have sound. If this is the case, check the following.

· The cable connecting the device and the TV is secure and working.

· You’re the audio output is enabled in your device settings.

· The CEC controls are enabled, known as ‘VIERA Link’. Found in ‘Menu > Setup > VIERA Link Settings > ON’.

· The TV speakers are enabled if you don’t have an external speaker. Found in ‘Menu > Sound > TV Speakers’.

You should also check the TV audio settings. You can find this under ‘Sound’ or ‘Audio’ in the main menu. Make sure the TV speakers have been enabled (unless you have an external speaker) and check the HDMI audio settings under ‘HDMI Input’.

External Speaker Issues

If you have an external speaker, check the following.

· The TV speaker has been disabled in the audio settings mentioned above.

· The ‘Audio Preference’ is set to an external speaker. Found in ‘Menu > Sound > Audio Preference’.

· Check the connections between the speaker and the TV are secure and in the correct input.

Panasonic TV Has No Picture

If there is no picture on your Panasonic TV at all, regardless of which channel you are using, there are only two ways of fixing the problem.

· Perform a hard reset (see above)

· Replace the circuit board

A hard reset will clear the TV’s memory of any temporary faults. If you do manage to get the image back, it might be worth performing a factory reset to prevent it from happening again.

A broken circuit board requires replacement or repair by a technician. If your TV is still under warranty, this will be done free of charge.

If your TV has the picture on all channels but one (or some), it is more likely a connection problem. First make sure you are using the channel that corresponds to the port your device is plugged into. For example, select ‘HDMI 1’ from the source menu to view the device plugged into the ‘HDMI 1’ port.

Once you’re sure you are on the right input channel, check if the cable is loose. You can also try a different cable or choose a different port. If it is the satellite TV that has no picture, make sure you have tuned the channels and that the antenna is in the right position.

If these solutions do not work, you may need to perform a hard reset or factory reset of the TV.

Panasonic TV Flashing

Many Panasonic users have had trouble with a flashing red light on the front of their TV. This indicator light means that the TV has detected an error of some kind. This can be rectified by unplugging all devices from the TV and then performing a hard reset (detailed above).

This process will clear the error from the TV’s short-term memory and allow you to plug in each device individually to isolate if they are causing the issue. If the hard reset does not solve the problem, you may have to contact a Panasonic technician to determine if the issue lies within the hardware.

However, if it is the screen that is flashing, this is more likely an issue with device connections. The solutions to this are similar to those mentioned above, under ‘Panasonic TV Has No Picture’.
