[Solved] LCD not displaying, using Marlin and RAMPS 1.4

I bought RAMPS 1.4 and a full graphical LCD controller.
First thing I did was install Arduino IDE 1.05r2 on Windows 7 and the newest version of Marlin on GitHub. I also put the U8glib (included in Marlin) folder in Arduino library and uncommented #define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER.

However when the LCD is plugged to the RAMPS board with two IDC connectors, the LCD just lights up blue, no text or graphic.
I'm powering with the provided computer USB cable.

Is this a firmware or hardware issue?

Have you tried adjusting the LCD contrast? There's usually a trimpot somewhere on the board for this purpose

Adjusting the LCD contrast does not appear to be the issue.

However I noticed there is a place for a surface mount component which is not placed, could this be the issue?
You can see in the picture it says RV and 3K whatever that means and there is screen print indicating a component.

I'm a moron, I should've set #define motherboard=33 for ramps. I overlooked that being too anxious getting the LCD to display something, LOL.
