Panasonic televisions are widely used home theatre systems. However, like any other TV, Panasonic TVs can experience malfunctions. For instance, when your Panasonic TV is in standby mode, the indicator on the TV blinks red, but there is no sound or picture. However, when you turn on the TV, the LED lights up with a different colour. Sometimes, images may appear on your TV, but there is no sound. Although it may play music, there is no visible image. Another scenario is when the Panasonic TV produces neither sound nor image. Each of these problems has unique root causes.
Do you own a Panasonic TV? Whether you have a Panasonic TV or any other brand, you should know the basic troubleshooting procedures. In this article, we will show you how to easily address the Panasonic TV black screen issue without picture problems. Keep reading to find out more.
How to Fix Panasonic TV Black Screen and No Picture Issues
No Image on Your Panasonic TV? How to Fix It?
There are only two solutions if your Panasonic TV has no image, regardless of the channel you are watching:
• Perform a full device reboot.
• Power off the circuit board.
This would clear all temporary errors from the TV’s memory after a full reboot. If you can get an image, it might be worth performing a factory reset to prevent the recurrence of this issue.
A specialist should replace or repair the damaged circuit board. This is done for free if your TV is still under warranty.
If your TV displays images on all channels except one (or several), the issue is most likely related to the connection. First, make sure you are using the channel corresponding to your device’s port. For example, to see the device connected to the “HDMI 1” port, select “HDMI 1” in the “Source” option.
Check if the cable is disconnected once you ensure you are connected to the correct input channel. Additionally, you have the option to try a new cable or port. Ensure channels are tuned and the antenna is set up correctly if the issue is related to satellite TV.
You should perform a hard or factory reset of the TV settings if none of these fixes work.
What Should I Do If My Panasonic TV Screen Is Black But There Is Sound?
Your TV may go dark while still emitting sound. Try restarting the TV to see if that resolves the issue.
If restarting the TV doesn’t work, your TV’s power source is likely faulty.
A damaged capacitor, which often occurs during voltage surges, is the cause of power source damage. To prevent damage, it is highly recommended to use a surge protector with your TV.
At this point, it would be best for a certified technician to inspect your TV and replace any broken parts.
Why Is My Panasonic TV Screen Half Black?
Let’s assume the screen panel of your PANASONIC TV (or any other TV for that matter) is shattered to pieces. Consequently, repairs are never cost-effective. The screen panel constitutes 90% of the TV’s cost, but factoring in the labour costs, replacing the screen is never economically viable.
Before contacting customer service, make sure the issue is related to the connected TV, cables, and peripheral devices. Poor broadcasting signals and issues with the panel and mainboard are two common causes of half-screen displays.
A faulty HDMI cable, poor backlighting, or interference from connected external devices—all of these can result in one side of the TV screen being excessively dark. Backlight malfunction is the most common cause. These indicators may only be partially illuminated on one side, causing that side of the screen to appear black.
The power cord of your digital device should be unplugged from the outlet; you should wait for 30 seconds before plugging it back in. Check if the image appears after the device is fully powered on again. If this doesn’t work, you can try reestablishing the HDMI connection if your TV is connected to it via HDMI.
FAQs
How can I fix the red flashing light on my Panasonic Viera?
First, try performing a power reset.Once you’ve powered off the TV, disconnect the power cord from the outlet. Then, switch off the TV completely. Then hold down the power button on the TV (or switch) for 30 seconds before releasing it. Plug the electrical cord back into the outlet, then turn on the outlet.
Why is the power indicator on my TV blinking?
With the TV on, the indicator is either steady green or white on the front panel of the device. Pressing the button on the remote control causes the green or white indicator to blink, indicating that the TV has received a signal. This feature is not available on some TVs.
How does Panasonic TV Anywhere work?

Why does my Panasonic TV have 7 red flashes?
Seven flashes indicate a malfunction in the SC, SU, SD, or all three boards. According to my technical data, this occurs due to heat buildup caused by a poorly designed heat dissipation system (heat sink).
