    I just purchased a reprap discount smart lcd and it just flashes and beeps. I tried both of your firmware versions, tried the newest release of marlin and uncommented the section for this lcd etc… tried switching the wiring terminals.

    No luck any ideas?
    It wont display, just a quick backlight flash and beep every second and n display at all.
    I am using the MKS gen 1.4 board.

    Did you change everything else you need to for the nks boards in the firmware?

    The one I have had the ribbon cable terminals on backwards. I had to pull off the plastic housing off the board so I could turn it around. you will need to follow the #1 pin to verify.
