The main reasons your Sony TV is flickering are problems with the power supply or cables, backlight panel issues, or wrong display settings. To fix this issue, ensure all the hardware parts work, restart the tv or adjust picture settings. You can also try updating the operating system.

Still unsure about what you should do? In the rest of this article, I will explain all these causes in detail and then go through all the solutions step by step.

Reasons Why the Screen of My Sony TV Is Flickering

There are a few possible reasons why your Sony TV is suddenly flickering. Some of them are related to the usual wear and tear of hardware, while some others might be a little more complicated.

Damaged Cables

Damaged cables can be the reason why your Sony TV screen is flickering. In particular, the HDMI cables often used to connect your TV to another device are likely the culprit. These cables are pretty delicate, so any form of damage may cause connectivity issues.

If you’re using a streaming device or a gaming console, you usually need an HDMI cable to connect it to your TV. A faulty connection between the two will affect the display, making it impossible for you to watch anything. 

Damaged Backlight Panel LED Lights

Another possible hardware issue is a faulty backlight panel. Your Sony TV contains a panel made of LED lights that backlight your display. Over time, the LED lights in the backlight panel might become faulty or break. This panel is essential to the quality of the images you see and once it gets damaged, you’ll notice issues with the display, including flickering.

Advanced Picture Settings

Sometimes advanced picture settings cause issues with your Sony TV screen. As a modern, high-tech TV, your Sony includes an array of advanced features that help improve your user experience. 

However, these features can sometimes become too much for the TV to handle. Brightness settings, in particular, can overburden the backlight panels, which can cause the screen to flicker.

Problems With Power Supply

Your Sony TV is supposed to work using a stable electric current. However, a stable and sufficient power supply might not always be possible. This might happen because of general power issues in your home or area, but also because the cables that supply your TV with electric current might be faulty.

Outdated Operating System

Sony smart TVs have operating systems that need constant updates to optimize your user experience and get rid of different issues. One reason why your screen is flickering might be because your operating system is outdated. An outdated system can result in bugs and glitches that may be causing the display issues in your TV.

No matter the issue, there is no need to panic and throw away your perfectly good TV. Plenty of solutions can help you stop the flickering effect and fix your screen.

If it’s a temporary issue because the cord simply isn’t connected well, you might just need to unplug your TV. Remove the power cord from the TV and the power outlet, and then plug it in again. 

2. Fix Issues With Cables

Like with the power cord, try to see if the cables connecting your TV to your devices are damaged or faulty in some way. Before you check any cables, make sure to unplug the power cord of your TV to avoid any injuries.

Once you’ve unplugged your Sony TV, unplug all the cables. Inspect and clean them carefully and clean their ports on the TV as well. When you make sure there are no damages and obstructions, plug them securely, making sure they are tightened. After plugging everything back, turn on your TV to see if the flickering is gone.
