Thank you for contacting Sony Online Support.
We understand that you have query regarding firmware update. We would like to inform that the Sony BRAVIA line of flat-panel LCD televisions reflects our commitment to the highest picture quality standards. The KDL-40XBR2/3 and KDL-46XBR2/3 series televisions have received exceptionally high ratings for picture performance from many well respected home theater sources, including the Editor?s Choice Award from CNET? and critics at Sound & Vision Magazine.
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, the setting, under certain dark viewing conditions, especially blank screens with no video source, may cause the screens on some of these televisions to exhibit slightly uneven uniformity. 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 does affect 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: 10)
A combination of the above changes may be applied as necessary.
If your television still does not meet with your approval after these setting adjustments, Sony Electronics will provide a Self Service Software Update that will further minimize the condition. Upon request, Sony will ship this update with directions directly to you when it becomes available in mid-February.
All terms of your Sony limited warranty continue to apply. We apologize for any inconvenience that this may cause, and we continue to stand behind our product and our loyal customers.
Please contact Sony at 1-800-222-SONY (7669) for more information.
Thank you for the opportunity to be of assistance.
