If you’re experiencing an annoying flicker on your Sony TV screen, you’re not alone. This common issue can be frustrating and disrupt your viewing experience. To help you understand the reasons behind this flickering and find a solution, we’ve compiled a comprehensive guide.
Causes of Sony TV Screen Flickering
1. Faulty Power Supply
A faulty power supply can cause fluctuations in the electrical current reaching your TV, resulting in screen flickering. Check if the power cord is securely connected to both the TV and the outlet. If the issue persists, you may need to replace the power supply unit.
2. Loose Connections
Loose connections between the TV components can interrupt the signal, leading to flickering. Inspect the cables connecting the TV to external devices, such as set-top boxes or soundbars. Ensure they are firmly plugged in and free of damage.
3. Software Glitches
Software bugs or updates can sometimes cause flickering. Check if there are any available software updates for your TV and install them. If the flickering persists after the update, you may need to reset the TV to factory settings.
4. Backlight Issues
The backlight system in your TV illuminates the screen. When the backlight is faulty, it can cause irregular flickering. If the flickering occurs only in certain areas of the screen, it may indicate a problem with the backlight LEDs.
5. Panel Defects
A damaged or defective TV panel can lead to flickering. This is usually caused by physical damage or manufacturing defects. If the flickering is accompanied by lines or spots on the screen, it may be a sign of a panel issue.
6. External Interference
Electromagnetic interference from nearby devices, such as microwaves or cordless phones, can interfere with the TV’s signal, causing flickering. Try moving the TV away from potential sources of interference.
7. Overheating
Excessive heat buildup can cause the TV’s components to malfunction, resulting in flickering. Ensure that the TV has adequate ventilation and is not placed in an enclosed space.

1. Check the Power Supply
Connect the TV to a different outlet or use a surge protector to ensure a stable power supply.
2. Inspect Connections
Unplug and reconnect all cables connected to the TV, including HDMI, power, and antenna.
3. Reset the TV
Perform a factory reset on your TV to eliminate any software issues. Note that this will erase all custom settings.

Check for available software updates and install them to address any known flickering issues.
5. Contact Sony Support
If the flickering persists despite the troubleshooting steps, contact Sony Support for further assistance.
