bravia goes darker in dark scenes an goes brighter in light scenes

[mi6-bond]

the tv is a kdl 40v 4000. i hope you guys understand what i mean lol.its mainly when i watch movies off my hardrive(ps3).in darker scenes the tv kinda dimms a little then it goes back to normal brightness when it recognises a lighter scene.im allmost certain its the tv an not the ps3 cos ive noticed it while watching end credits of a ps3 game[when white credits popped up its fine,when they scroll off it dimms]. is it some kind of energy saving feature i can turn off(ive looked everywhere). as i say, i hope you see what i mean. thanks guys

Could be some of the advanced menu settings - such as dynamic contrast. This continually adjusts the contrast levels based on the image shown on screen, so may explain why it changes between dark/light scenes.

You must have you picture setting on dynamic. To stop this, change to Normal and go into advanced picture settings. Choose Adv Contrast Enhancer to off.
