I have an issue with my new X900F Bravia TV, where the backlight flickers if there is anything moving on screen and X-Tended Dynamic Range is turned ON. It happens whether it is on Low, Medium, or High.

I understand that X-Tended Dynamic Range is supposed to dynamically brighten and darken parts of the image, however instead of doing this smoothly the backlight is noticeably flickering everytime it does it. I have Eco Sensor off and have tried turning all other enhancements off too, but it still happens on every input.

It didn't seem to do this when I first purchased the TV, could this be a fault with my set?

Hope someone can help.
