Blank ILI9341 screen using esp32 s3

Did you find some errors in Serial Monitor?

I found the following error with ESP32-S3 (XIAO) & ILI9341 (2.4") when I execute TFT_graphicstest_PDQ :

I my case, I have the following enabled in User_Setup.h to solve my issue:

// The ESP32 has 2 free SPI ports i.e. VSPI and HSPI, the VSPI is the default.
// If the VSPI port is in use and pins are not accessible (e.g. TTGO T-Beam)
// then uncomment the following line:
#define USE_HSPI_PORT // or USE_FSPI_PORT

You can find some issues related to TFT_eSPI, ESP32-S3 and ESP32 Espressif board package 3.x. For example:

Hope this helps to solve your issue.
