hello, i have read this:

Bit      Dec    Option Name               Description
bit 7   128    1080P                         On = 1080p Available Off = 1080p Not Available
bit 6   64      LIGHT_SENSOR            On = Light Sensore is Available Off = Light Sensor is Not Available
bit 5   32      AMBILIGHT                  On= Ambilight Features Will Be Available Off = Ambilight Features Will Not Be Available
bit 4   16      BACKLIGHT_DIMMING   On = Backlight Dimming is Available Off = Backlight Dimming is Not Available
bit 3   8        HUE                            On = Hue is Available Off = Hue is Not Available
bit 2   4        2D3DCF                      On = 3D Comb Filter is Available Off = 2D Comb Filter is Available
bit 1   2        WSSB                         On = WSS is Available Off = WSS is Not Available
bit 0   1        WIDE_SCREEN              On = TV is 16x9 Set Off = TV is 4x3 Set


So to turn off the backlight diming you will need to subtract 16 from the value of Opt 2. In my case Opt 2 had a value of 157, which means bits 7, 4, 3, 2 & 0 are On (128+16+8+4+1=157). With backlight dimming turned off my Opt 2 value becomes 141.



-----------------

i have turned off the backlight dimming
my tv at opt 2 has 23

now the number is 7 (23-16=7)

and now i want to remove light sensor too.

my question is:
to get off the light sensor off what number need to get off?
at opt 2 needs to subtrackt 64? 7-64?
