I just bought an LCD high def Sony bravia KDL-26m4000 TV and I've noticed that when the picture changes, the TV adjusts the brightness accordingly. I did some research and found that this is called Advanced Color Enhancement. There is no menu option for this on my TV and I can't get it to stop by adjusting any of the other settings. I even have Light Sensor off.

How do I turn ACE off of there is no menu option for it?
