Replaced Mogul dimmer?

[SINNN]

Ok.. I got a warranty replacement Mogul and I have a issue with it. Its not refurbished and its the new batch because it does not have the Pocket PC print on the front. My issue is if I enter the screen brightness control and set the level all the way down then the screen backlight shut off completely. I know for a fact tghis should not happen because my First Mogul when I set the level all the way down the light did not go off but went very dim. Also my GF has a Mogul and hers dont shut down completely too. It just dims very low just like my first Mogul. This is affecting the overal brightness of the screen because if I set this new mogul next to my GF mogul her screen is clearly brighter by one notch. Has anyone come across this issue? Did i get a lemon?
