On my 12864 LCD board all I get is a blank screen with a backlight. Do not get any text at all! I am running 2560 ramps 1.4 and Marlin. I have tried switching the connectors on the board I have also checked the continuity of each wire on both plugs continuity is fine on every wire. I have uncommented lines of code that were suggested on YouTube. The contrast works okay I can adjusted and it gets darker and then if I adjusted the other way gets lighter. Just checking to see if there is anyone that can help me?
