Burn-in, or permanent image retention, occurs when static images are displayed on an OLED screen for extended periods, leading to lasting discoloration.

The Sony A90K 48-inch OLED TV incorporates several features to mitigate this issue, but if burn-in has occurred, addressing it promptly is essential.

Understanding Burn-In:

Burn-in results from prolonged display of static content, such as channel logos or video game HUDs, causing uneven pixel wear. This differs from temporary image retention, which typically resolves on its own.

Preventative Measures:

To minimize the risk of burn-in on your Sony A90K:

• Enable Pixel Shift: This feature subtly shifts the image to distribute pixel usage evenly.
• Activate Screen Saver: Set a screen saver to engage during periods of inactivity.
• Adjust Brightness Levels: Lowering brightness can reduce pixel strain.
• Utilize Auto-Dimming: Enable settings that dim the screen when static images are detected.

Addressing Burn-In:

If burn-in has already occurred:

1. Run Pixel Refresh: The A90K includes a panel refresh function designed to correct image retention. Access this through the TV’s settings menu.
2. Display Varying Content: Regularly viewing diverse content can help alleviate minor burn-in over time.
3. Consult Professional Service: For severe cases, contact Sony customer support or an authorized service center for assessment and potential repair.

Warranty Considerations:

It’s important to note that Sony’s standard warranty may not cover burn-in, as it’s often considered a result of user habits. Review your warranty terms or consult with Sony support for clarification.
