can not run TFT009-81AINN using ST7735S driver

[smarq8]

Hello I prototype some board with TFT009-81AINN display, it use ST7735 controller, pin1 tied to VCC for 4 wire spi, I already fixed missing connection at pin12 (backlight). I tried any tc parameter for tft.ini(tc) without succes. I also check signals by osciloscope and it seems fine. My MCU - ESP32-WROOM-32D. Any solution what I'm missing or does this library support it? Also does it metter if TFT_RES is connected to IO5 (pwm at boot)? Its reasaon why I put delay(1000).

main.cpp

#include <Arduino.h>
#include "TFT_eSPI.h"

TFT_eSPI tft;
void setup(){
    Serial.begin(2000000);
    delay(1000);
    tft.init();
    tft.setRotation(1); // not yet sure
    tft.fillCircle(15,15,10,tft.color24to16(0xff0000));
}

void loop(){
    Serial.printf("%u\n",millis());
    tft.fillCircle(15,15,10,tft.color24to16(0xff0000));
    delay(200);
}

I think I found issue. It was cold solder joint on a connector between MCU and display on SCLK line. Also I provide here working setup:

main.cpp

#include <Arduino.h>
#include "TFT_eSPI.h"

TFT_eSPI tft;
void setup(){
    Serial.begin(2000000);
    tft.init();
    tft.setRotation(1);
    tft.fillScreen(tft.color24to16(0x000000));

}

void loop(){
    tft.setCursor(10,10);
    tft.setTextSize(2);
    tft.printf("hello world\n%u",millis());
    tft.fillCircle(10,50,10,tft.color24to16(0xff0000));
    tft.drawRect(1,1,160-2,80-2,tft.color24to16(0x0000ff));
    Serial.printf("%u\n",millis());
    delay(1000);
}
