ILI9486 power on with white screen.

I use the same all config with the ILI9488 screen.
Only change the pin configuration.

#define PIN_NUM_MISO 39//19 // SPI MISO
#define PIN_NUM_MOSI 22//23 // SPI MOSI
#define PIN_NUM_CLK 19//18 // SPI CLOCK pin
#define PIN_NUM_CS 32//5 // Display CS pin
#define PIN_NUM_DC 27//26 // Display command/data pin
#define PIN_NUM_TCS 33//25 // Touch screen CS pin (NOT used if USE_TOUCH=0)

// --------------------------------------------------------------
// ** Set Reset and Backlight pins to 0 if not used !
// ** If you want to use them, set them to some valid GPIO number
#define PIN_NUM_RST 0 // GPIO used for RESET control

#define PIN_NUM_BCKL 0 // GPIO used for backlight control
#define PIN_BCKL_ON 0 // GPIO value for backlight ON
#define PIN_BCKL_OFF 1 // GPIO value for backlight OFF
