LCD display has no display or dark blocks. 2 Years, 3 Months ago  
Q. The LCD display has no display or the display has dark blocks on it. Why?

A. There may be a problem with the contrast level. The potentiometer (contrast control) is located on the back of the keypad/display board. Unlock the front door and adjust the potentiometer for a darker or light contrast display.
