I know what's the issue there... You've used PNP transistor instead of NPN transistor to take care of the LCD backlight (or the other way around NPN instead of PNP - depends on the LCD setup). Switch to similar transistor but of different type and your problem will disappear.

Good luck!

Gerhard Plattner: "The best attitude is to consider fuel saving a kind of sport. Everybody who has enough money for a strong car, can drive fast and hit the pedal. But saving fuel requires concentration, self-control and cleverness. It's a challenge with the nice effect of saving you money that you can use for other more important things."
