mks gen v1.4 LCD wont turn on.

Hey guys

LCD 12864 wont turn on, on my MKS gen 1.4

Here are some info:
LCD 12864 is from Anet A6 <--- might be the problem.
Marlin firmware - tried different version.
and yes, define motherboard to BOARD_MKS_13
and LCD to define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER
flipped cables to lcd 180 - did not work, blue flash on board (D4) when i did this.

Now, if it is because of the Anet LCD, ill wait on another LCD 12864

i hope this is enough info right now.

thx in advance.

the LCD gets "warm" but wont light up, so its getting power, but nothing happens
