Full Graphic Smart Controller - Blank Screen

Hi all!

I've got a Ramps 1.4 with a RepRap Discount - Full Graphic Smart Controller - 12864.

The problem is that the display board is working, I can see from serial output that sd card is detected, buzzer is working and also the encoder.
The only problem is with the display itself which is not displaying anything, as from the image.

I can confirm the hardware is ok as it was all working with the previous version of the marlin firmware, just I can't remember which where to correct settings.
Can anyone help me?



This is the serial output:
