You know SD-card support often has to be enabled in firmware?

Could you supply more information.
What firmware you are using, LCD type, configuration settings could be helpful in helping you fix the SD card reader.

The LCD12864 is not the Discount smart LCD, but the graphic LCD...

to get the display working i have to set the marlin to use

#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER

so i assumed this was the name for it but your comment doesnt help me fix the SD card issue.

I looked over your firmware and only saw this

#define FIX_MOUNTED_PROBE // Should be enabled when using "#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN"

I would suspect that you might have a bad SD driver chip on your LCD, I know how this sounds but is the SD cable plugged into the right port on the controller.
And last Where did you download the Marlin Firmware it could be corrupted.

I had the "SD Card Inserted" message on the main screen, But when I went into the menu system to print from SD, is said "No Card".
Using marlin 1.1.9. with a LCD 12864 onto the RAMPS 1.4 board on a Chinese Mega Clone.
SD Card was a 2GB card that I had in an old camera. - reformatted
Yes, #define SDSUPPORT was enabled in configuration.h file
Yes, the ribbon cables from the interface board to the 12864 were correct.

Things attempted:
1) Wringing out wires, checking pin for pin between 12864 and the interface board. (beware that the schematic on REPRAP for the breakout board shows AUX3 wired wrong) No Luck
2) Performed a somewhat exhaustive search of the firmware for pin assignments (configuration.h, pins_RAMPS.h & cardreader.h seem to be the only files that deal with the card reader) No Luck
3) Formatted SD card in FAT, FAT 32, and also some sd card specific formatter that was suggested in another forum. No Luck
4) Replaced 12864 board (with plugin board) No Luck
5) Replaced Arduino board with another clone from a different manufacturer. No Luck
6) Replaced RAMPS 1.4 board. No Luck
7) Attempted re-flashing firmware with an old marlin 1.0.x No Luck

Final solution after 2 weeks of pulling my hair out: Tried different SD Card. Worked the first time! No Formatting!!!!

Why did I not try this sooner? I was convinced that the original SD Card was good because it worked fine in two different computers.

Moral of the story: Try the simple stuff first. It may save you from going bald!
