White Screen on arduino Mega

The problem is pretty straight forward, I only get a white screen while trying to run grapicstest.
These are my connections:
#define TFT_DC 48
#define TFT_CS 49
#define TFT_RST 47
#define TFT_MISO 50
#define TFT_MOSI 51
#define TFT_CLK 52
I connected the latter 3 on the hardware spi pins and also tried normal pins.
When running the graphicstest in the normal adafruit ili9341 libary it does work.
Does anyone know what could be wrong?
