I don't think the wires are the problem because the printer works fine for a moment, exept it can't communicate with the computer. Then the blocks start to appear. I am trying to re-upload the firmware but I am not shore that it is the problem. Thank you for your help

hi,please tighten or loosen the small screw at the back of the LCD.it's used to adjust the contrast ratio.
