mini12864 + marlin (no replies)

Hi, How is it possible to get following combination to work?
BTT MINI 12864 V1.0 display with SD + MKS GEN L 2.1 + marlin 1.1.9.1

Cables are turned 180deg on MKS GEN L and REPRAP_DISCOUNT_SMART_CONTROLLER / LCD 2004 works fine.

Only two leds and maybe lcd backlight turns on in MINI 12864 when REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER is enabled.
