Not all phone LCDs, (Liquid Crystal Displays) have the back light in the LCD.

If you have the circuit board look for LEDs, (Light Emitting Diodes) under where the LCD was.

They may be SMD, (Surface Mount Device) or they may be hole through that looks like a white rectangle and the LED emits out the side to the LCD.

Most LCD backlights are the last two contact points so if you know which pin is pin 1 and there are 12 pins it would be pin 11 and 12.

You can try a multymeter set for continuity and checking to see if it lights up when you connect to the right pins, this doesn't always work.

On the datasheets they are marked K A see my Instructable Salvaging Liquid Crystal Displays (LCDs)
