RepRap Full Graphics Smart Controller Help

Hi
I have bought the RepRap Full Graphics controller and trying to get Marlin to recognize it. I have added u8glib added into arduino's libraries and restarted the Ramps 1.4 Baord.
When I uncomment the Line " LCD and SD support, the " SD " turns red.
I also uncomment #define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER
Then I try Verify I get an error " LCD does not name type "

Not sure why SD would tuen red and not be able to upload ?

Thanks

Hi
Sorted it out and got it working but now have another problem, the contrast is so bad you can hardly see anything. I try change it on the controller but nothing happens.
Any advise.

Thanks

There is another thread that covers this very topic in the "controllers" forum.

Essentially, some of the RRD GLCDs have a tiny pot on the back of the LCD board near the SD card socket. You can turn that pot with a pair of tweezers. Some do not have a pot and you have to solder resistors in a couple places.
