i meant to say LCD, my bad...

I recomend searching a LCD tutorial. it normally shows what must be connected where. The way to test if LCD is working is to connect power to it (pins 1 & 2) and also power thecontrast pin with whatever voltage it needs. The backlight unit is independant and requires 4.2V ~160mA.
