[Solved] A lit LCD appears squares, but without subtitles
After dozens of hours of printing and everything was fine, I decided to clean the printer, lubricate and strengthen and the like. Somehow the LCD display appears 2 lines with the boxes without subtitles. I tried to check if the LCD cables are well connected.- Yes well connected. So I downloaded and updated. The software says it worked well. But do not see the subtitles. What to do?
