      Hello, o buy a LCD raystar screen blue 12864a .

      Can you Help me in One Isseu?

      The screen works but the color blue is off.

      I check the pins 19 (+5 v) and 20 (gnd) and it os ok.

      Why the blue color don't works?

      Thank you

        Which Duet have you connected it to? What controller does the screen use? Photo of what you're seeing?

            I believe you have to feed the backlight from the "A1 + K1" pins. Same red and black wire as on the old LCD.
