LCD Screen shows squares

I have a concern regarding the Prusa i3. When i connect the printer to my computer via USB the LCD panel on the printer works absolutely fine but as soon as i turn the power supply on for the printer, the LCD panel starts showing all squares. All the text is gone but when i cut off the power supply the LCD panel is back to normal, i can see the text correctly. 

Anyone experience that before?
