Causes of Sony TV Screen Flickering
1. Power Supply Issues
Insufficient power supply can cause the TV screen to flicker or turn off intermittently. Check if the power cord is securely connected to both the TV and the power outlet. Try using a different power outlet to rule out any electrical issues.
2. Backlight Problems
The backlight system provides illumination for the TV screen. If the backlight malfunctions, it can cause the screen to flicker or dim. This issue may require professional repair.
3. Firmware Bugs
Software bugs in the TV’s firmware can also lead to screen flickering. Check if there is a firmware update available for your TV model and install it. Firmware updates often address performance issues and bug fixes.
4. Component Failure
Internal components within the TV, such as the mainboard or the power supply board, can fail over time. This can result in various issues, including screen flickering. Component failure usually requires professional repair.
5. Loose Connections
Loose connections between the TV and external devices, such as a cable box or Blu-ray player, can cause flickering. Check all cable connections and ensure they are securely inserted.
6. Electromagnetic Interference
Electromagnetic interference from nearby electronic devices, such as microwaves or cordless phones, can disrupt the TV’s signal. Move the TV away from potential sources of interference or use shielded cables.
7. Panel Defects
In rare cases, screen flickering can be caused by a manufacturing defect in the TV panel itself. This issue is usually covered under warranty and will require professional repair or replacement.

1. Restart the TV
Restarting the TV can often resolve minor software issues that may be causing screen flickering. Unplug the TV from the power outlet for a few minutes and then plug it back in.
2. Check the Power Supply
Ensure that the power cord is securely connected to both the TV and the power outlet. Try using a different power outlet to rule out any electrical issues.

4. Reset the TV to Factory Settings
Resetting the TV to factory settings can resolve software glitches that may be causing the screen flickering. Note that this will erase all custom settings and stored data.
