    I have purchased the Full Graphic Smart Controller with a RUMBA board and I don't get it to work.
    I have followed the simple instructions from http://reprap.org/wiki/RepRapDiscount_Full_Graphic_Smart_Controller using a clean Marlin_v1 firmware and the screen lights up but it is totally blank, no startup screen, nothing at all...
    I have attached the LCD to the RUMBA as it is supposed to work: LCD EXP1 to RUMBA EXP1 and LCD EXP2 to RUMBA EXP2...

    Anyone having this problem or I have a defective screen?
    Thanks in advance

    Actually all our lcd are tested one by one. In most of the case it's a issue of the configuration, please check this carefully.
