"I'm using YJ161A LCD in my project. The data to this is controlled using AT89C52 uC. I've tried 3 different codings but failed to get any output. YJ161A is a 16*1 LCD, but only first 8 Characters are enabled (blank - No characters). What can be the problem? Could there be a problem with LCD. Should I try with a new one?"

Is the LCD contrast or bias control set properly?
