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?

This sounds like an earthing problem, 'though it could be a bad usb connection/socket/lead.
Check the mains earth connections are clean and tight on both the printer and computer. Try using a laptop on battery power. Try a different usb cable.
Cheerio,
