What exactly is 'not working'. Be more specific. Are you using the TextLCD lib? Did you select the 16x4 display type.
when i connected the LCD 16*2 (hardware) it functioned normally, but i changed it to 16*4 it displayed black squares, and i didn't know what it was i had to change, im using assembly language with PIC18F4450. so i don't know if i have to change something in the hardware or in the program. if its in the program and you have just the part for the LCD it will be perfect, and if its in the hardware connection what could it be. Thank you for you continues help.

When the LCD shows black rectangles it means that powersupply is OK, but the display is not initialised properly. Check your wiring (data, Enable, RW, RS) and check the timing for the init sequence.
