Hey Guys, new to the forum. I built a printer a few years back and I'm having an issue with the LCD display. Its a basic rep rap display kit. It's worked fine for all this time and now all of the sudden, after I start the print, the lettering disappear and its just blank. Everything works fine, even up to when I start the print, but after a min or two of printing, it goes blank.
