Hello,
I bought 4 days before Acryl Prusa I3 Pro B. Machine prints well with Repetier-Host and USB, but I have a problem. The LCD display turns green and don't have any symbols on it. I checked the cables for the SD card and the display, it OK. Also when I press the main switch board beep.

I will ask for help!

Hi,
Try to ronate the potentiometer behind the LCD controller panel to adjust the voltage.

Thank you so much! Now everything is OK. The printer works well.

Nice work!
