"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?

Thanks

Several years ago I had such a display. The fix was to read the address after each write, if it was '08h' then add a value that offset that next address to the appropriate 'next' address. In my case it was to set that next address to '28h' (decimal 40), and then it worked properly. Hope this works for your LCD.
