Hi I have just termineted a home made Prusa and I have problems with the display.
Like i say it works half only the rgb lights and i cant see nothing. on screen.
I tried a lot my be some know something more.
My config is Ramps 1.4 with ramps lcd adaptor (im not sure if are well connected)
Arduino mega and mini LCD Fysec MINI12864 like i said. In Marlin 2.0.4
This is my extracted config. and config.adv.

This was connected with my old rerap red adaptor to ramps EXP1 with EXP1 and so on.
I read somewhere that y must make a cable and change the pins i dont know doing that.
I dont know if The contrast is software problem or not.
Thanks for any kind of help.
