The mpguino uses pwm for contrast control bobski, to keep the component count down, and thus improve the chances of getting it right, it sounds like the contrast part is working.

Frank, something might be miswired or there may be a problem with the LCD, the half screen of blocks is a common symptom of a loose or bad connection. Maybe all the button pressing is aggrivating an existing bad connection?
