HI Dudals-Jung, Here are 4 things to test -

What does the serial monitor show?
Does the backlight blink at the start?
Is your board set to "ESP32S3 Dev Module"?
Is PSRAM set to "OPI PSRAM"?

I had the same issue and it was basically the backlight. In order to make it work the extender needs to be configured properly. The following settings after including pins.h did the trick: `#define TP_RST 1

define LCD_BL 2

define LCD_RST 3

define SD_CS 4

define USB_SEL 5

// I2C Pin define

define I2C_MASTER_NUM 1

define I2C_MASTER_SDA_IO 8

define I2C_MASTER_SCL_IO 9

However, it was more of a trial-and-error excercise, it's probably not a pretty solution but it worked for me.
