QVGA 2.2 TFT SPI display white screen problem

I've been struggling to get my 2.2" ILI9341 TFT LCD Display to work. Despite following various tutorials and trying different wiring setups, all I get is a white screen. Here's what I've done so far:

  • Checked and rechecked the wiring multiple times
  • Tried using the display without resistors in the wiring
  • Used the recommended libraries and code for the ILI9341

Additionally, here's the output I get from the serial monitor when running graphics tests:

18:40:43.313 -> Rectangles (filled) 3107216 18:40:47.338 -> Circles (filled) 465816 18:40:48.085 -> Circles (outline) 541572 18:40:49.126 -> Triangles (outline) 281668 18:40:50.195 -> Triangles (filled) 1339904 18:40:52.636 -> Rounded rects (outline) 243748 18:40:53.679 -> Rounded rects (filled) 3132656 18:40:57.619 -> Done!

The graphics tests seem to run, but the display remains white. I'm using an Arduino Uno with the following pin configuration:

VCC-5V
GND-GND
CS-10
RST-8
DC-9
MOSI-11
SCK-13
MISO-12
also backlight to 5V !

I would appreciate any guidance or suggestions on what might be causing the issue and how to resolve it.

Thank you in advance!
