The brightness is controlled by the Lite Pin. 0v for off, Vin for on. If you connected it to Vin and it didn't come on, the problem is deeper and controlling with PWM won't have an impact.

you can turn on the back lite with code or with just using 2 test wires, 5v to 'lite' pin and 'gnd' to ground. If it does not turn on with 5v to the 'lite' pin, it's what datsels said.
