What line or lines control the back light of this LCD? Answered

I have this radio/alarm clock/cd player with a really bright lcd screen even when it is off. In a previous question I asked how difficult it would be to disable the backlight without disabling the rest of the screen. They said it would not be difficult and to upload picks of the lcd screen with the radio disassembled. Well here it is.I have posted pictures of the front and back if you need anymore information or more pictures let me know.

You need to trace the ribbon back to the main (powered) board. One will be obviously GND, you should be able to identify the wire for the light as it won't connect to the display-driver IC.
All you'll have to do is cut one of the wires in the ribbon.

*You've photographed the wrong board.
