If you have a Panasonic TV that is no longer working, it can be very frustrating trying to work out what is wrong and how to fix it. Calling in a service technician for every problem can be costly and time consuming. This article outlines some of the main issues people face with Panasonic TVs and how you can solve those issues yourself.
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.
I will explain exactly what to look for and how to fix each of these issue below. You will also find a step-by-step guide for resetting and updating your TV.
Panasonic TV Not Working
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.
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.
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.
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.
Panasonic TV Won’t Turn On
Below are the most likely reasons why your TV won’t turn on and how to fix them. If none of the below seem to be the cause, try a hard reset, detailed above. If the TV is stuck in ‘Standby’ mode, this will fix the issue.
Compromised Power Supply
Make sure that the TV is actually plugged in to a working power socket that is switched on. You may need to try another socket to test this. If the TV is plugged into a power board, the outlet may be overloading, so it is best to plug it directly into the wall.
You can also check whether the cable is loose. Try unplugging it from the TV and re-inserting it so that it is snug. If you have access to a spare cable, you could also test if the power cable is damaged.
Remote Not Working
One possibility is that your remote is not working. If this is the case, your TV should still turn on using the power button on the back/side of the TV. If it still does not turn on, it may be one of the issues listed below.
If you suspect your remote control is not working, start by replacing the batteries. The next thing to try would be resetting the remote and trying to unstick any unresponsive buttons. Your power button could have debris trapped underneath, preventing it from responding when pressed.
Step 1: Remove the batteries from the remote.
Step 2: Press each button at least once to drain all power.
Step 3: Press the ‘Power’ button several times to dislodge any debris.
Step 4: Re-insert the batteries.
Sometimes the problem lies in the hardware of the TV, which is not going to be fixed by resetting the TV. These issues require a Panasonic service technician to assess and replace the broken hardware.
The most common issue occurs when the capacitors malfunction. However, it may also be an issue with the screen. You can find out more about a malfunctioning TV display below.
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’.
