LCD interfacing

Hi all,
I am interfacing 16x2 character LCD to P89LV51 and using 8bit interface mode, I am initializing the LCD by this sequence
function set - 0x38
display control- 0x0f
entry mode set- 0x06
cursur shift- 0x14
clear display - 0x01
and finally displaying the string
but after initializing, display is blank, instead of busy check, i used delay then, still the display is void. I used the LCD initialization as given HD44780U datasheet. Still No display. But Same LCD is working actually with some other code. Can somebody tell me the exact problem.
