check nyo po yung pin 3 ng LCD (Contrast)

adjust nyo po yung contrast sa Potentiometer.  ;)

Adjust the contrast. Kung nag work sa proteus, chances are mag work rin yan sa actual.

para sa anong LCD 'yung sample code? kapag kasi nag buong black na blocks 'yung line 2 at 4, naka-initialize siya para sa 2-liner.
