The Sony BRAVIA line of flat-panel LCD televisions reflects our commitment to the highest picture quality standards. The BRAVIA X-series televisions have received exceptionally high ratings for picture performance from various sources.
To achieve this high level of performance and picture clarity, Sony utilizes a very bright backlight setting. This helps deliver the brightest picture possible, as well as exceptional picture clarity even in the darkest image sources.
However, under certain dark viewing conditions, the setting may cause the screens on some of these televisions to exhibit slightly uneven uniformity, especially for blank screens with no video source. This condition is not usually visible under typical viewing conditions, such as watching movies or television programming, and generally should not affect your viewing experience.
Should you find that this condition affects your viewing enjoyment; there are a few settings that you can make to minimize this condition:
• Setup Menu --> Light Sensor: ON
• Setup Menu --> Power Saving: Low or High
• Picture Menu --> Reduce the Backlight Level (Factory Setting: MAX)
A combination of the above changes may be applied as necessary.
If you need any assistance regarding this issue, please contact your local service centre. A list of the Sony service centres can be found in the Service Centers Page.
