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.

I ended up in the same corner as you but couldn make it work.
The esp32 works (prints in the serial monitor, turns on an off the backlight) but the tft wont show anything
