A few days ago I connected an ILI9341 display to my raspberry pi. After installing all the required Python things, I ran a simple code and it just worked.
But because I have a little 5 V fan , that I took apart the connector, I connected it to 3.3 V. By mistake I shorted 3.3V and 5V line of the Raspberry Pi. Since then the screen is only white.
What is broken now, the Pi's SPI interface or my display? I have no way to test the display and the Raspberry Pi is still working fine. I can also control the GPIO 22 just fine (the GPIO that’s connected to the displays backlight).
The Pi works just fine, the display doesn't.
Note: The connection from the display to Pi are as follows:
MISO-MISO
SCK-SCK
3.3V-VCC
GND-GND
CE0-CE
GPIO 24-DC
3.3v-LED
