In general, when LCD is not turned on, anti clockwise rotation of the value on potentiometer shows a picture on the LCD. However, this is very rare case as products are tested before releasing. 
Please make an inquiry after checking that the voltage of the adapter is 4.5V and whether LCD Module is out of order.
