I want get rid off Screen Alignment in Samsung Omnia Problem

I did hard reset in samsung omnia lite GT-B7300.. but I am not able to do screen alignment. I am continuously taping the target but it is still moving. I did it for more than a hour but not able to go beyond screen alignment. Please some one help me to come out of screen alignmen and to start my cell in normal mode. Already I have changed the screen twice in two years time and I don't want to repeat the same..thanks,
