blank screen but still uploads code

[JandGprojects]

on my esp32 ttgo t-display it sees my computer and uploads code but the screen is blank when using my code that worked before and even the sketches. By the way I use the TFT_eSPI library and the cable still works since it uploads and connects to the board. Also I have had this happen to 2 of my boards now and one was brand new and had this problem.
I have tried many solutions I could find on the web but nothing has so far worked, does anyone have an answer to my problem?

I've got the same issue.

I have uploaded a simple test script to the board which, once loaded to the board, is able to output text to the serial monitor, and blink a led on GPIO 15 - but I am unable to get anything on the screen.

example script:

#include "TFT_eSPI.h"

TFT_eSPI tft= TFT_eSPI();
void setup()
{
    Serial.begin(115200);
    Serial.println("Setup Starting");
    pinMode(15, OUTPUT);
    digitalWrite(15, LOW);

    tft.init();

    delay(100);
    Serial.println("Setup Done");
}
int i=0; 
void loop()
{
    tft.setRotation(3);
    tft.fillScreen(TFT_ORANGE);
    i++;
    Serial.println("loop");
    digitalWrite(15, HIGH);
    delay(25);
    digitalWrite(15, LOW);
    // Wait a bit before going again.
    delay(5000);
    Serial.println("again");
}

I had the same problem. In my case I removed the old Arduino IDE and installed a new one(2.2.1).
Also I'm using a more recent version of the library TFT_eSPI, check that at https://github.com/Bodmer/TFT_eSPI/releases or type TFT_eSPI on Arduino library manager.

Edit the User_Setup_Select.h file on /Users/./Documents/Arduino/libraries/TFT_eSPI

Comment the line (add // to th beginning of the line)
#include <User_Setup.h> // Default setup is root library folder

And uncomment the line
//#include <User_Setups/Setup25_TTGO_T_Display.h> // Setup file for ESP32 and TTGO T-Display ST7789V SPI bus TFT

Yup this fixed it for me.
