2 x 16 lcd 4 bit mode

hi all,
I am using a pic to connect to a 2 x 16 lcd in 4 bit mode.
I can get the cursor to blink on and off, also move to any position on line 1 or 2. however when I come to display character the screen goes blank.
I am using a pic18f4550 and pic dem plus (microchip demo board).
here is my code:
(written in Mikro C)


#define TRUE 1
#define LCD_LINE_1 0x80
#define LCD_LINE_2 0x40


sbit RS at RA3_bit;
sbit EN at RA1_bit;
sbit RW at RA2_bit;

/* function prototype */
void lcdInit(void);
void lcdWrite(unsigned char);
void lcdOut(char c);
void lcdLine(unsigned char);
void configurePort(void);
void lcdStrobe(void);
void lcdWriteData(char);

char Hello [ ] = "Hello"; /*char string*/

void main()
{
int index = 0;
char outchar;
lcdInit();
lcdLine(0x01); // select first line, second line 0x40
//for (index = 0; index <5; index++)
while(TRUE)
{
outchar = Hello[0];
lcdWriteData(outchar); // write character data to LCD
}
}

void lcdInit()
{
ADCON1 = 0x07;
TRISA = 0x00;
TRISD = 0x00;
RS = 0; /* RS =0 - instruction to LCD, RS=1 character to lcd */
EN = 0; /* EN=0 lcd disabled, EN=1 enabled */
RW = 0; /* RW = 0 - data written to lcd, RW = high data read from lcd */

delay_ms(15); /* wait 15mSec after power applied, */
PORTD = 0x03;
lcdStrobe();

delay_ms(5); //5
PORTD =0x03;
lcdStrobe();

Delay_us(120); //120us
PORTD = 0x03;
lcdStrobe();

Delay_ms(5);
PORTD =0x02; //Four bit mode
lcdStrobe();

delay_us(40);

lcdWrite(0x28);
lcdWrite(0x0f); /* 0x0f D=1 display on, c=1 cursor on, b=1 cursor blink */
lcdWrite(0x06); /* 0x06 I/D = 1 inc cursor position, s = 0 - no display shift*/
lcdWrite(0x01); /* 0x01*/
}

void lcdWrite(unsigned char c)
{
unsigned char copy;
copy = c;
RS=0;
RW=0;
delay_ms(50);
PORTD = ( ( c >> 4 ) & 0x0F );
lcdStrobe();
PORTD = ( copy & 0x0F );
lcdStrobe();
}


/* Go to the specified position */
void lcdLine(unsigned char pos)
{
RS = 0; //0
lcdWrite(LCD_LINE_1+pos);
}

void lcdStrobe()
{
EN = 1;
delay_us(10); /* us */
EN = 0;
}

void lcdWriteData(char d)
{
unsigned char copy;
copy = d;
RS = 1;
RW = 0;

PORTD = ( ( d >> 4 ) & 0x0F );
lcdStrobe();
PORTD = ( copy & 0x0F );
lcdStrobe();
}
