user57195: I just bought the 3rd TFT and in all my attempts I get the white screen I don't know what I'm doing wrong!
This time I bought it and followed their instruction's guide 
I created this schematic using Fritzing which is the one I'm using but still I am getting the white screen again

Here are some Photos of what is the TFT displaying.   
Finally, I did also used the recommended testing code which is listed in: 
File > Examples > Adafruit ST7735 and ST7789 library > graphicstest
Also, I have did commented the slightly changed. So this is the code I'm using:
/**************************************************************************
  This is a library for several Adafruit displays based on ST77* drivers.

  Works with the Adafruit 1.8" TFT Breakout w/SD card
    ----> http://www.adafruit.com/products/358
  The 1.8" TFT shield
    ----> https://www.adafruit.com/product/802
  The 1.44" TFT breakout
    ----> https://www.adafruit.com/product/2088
  as well as Adafruit raw 1.8" TFT display
    ----> http://www.adafruit.com/products/618

  Check out the links above for our tutorials and wiring diagrams.
  These displays use SPI to communicate, 4 or 5 pins are required to
  interface (RST is optional).

Please don't mark this question as duplicated because I looked at the other guy he/she was using different guide.. the one I'm using is posted by the company I purchased the TFT from.

Replace your that part with one I suggested as You commented tha SCK and MISO pins in your code so no data transfer is happening on those pins. Secondly I made changes according to your hardware configuration as well.

<p>Replace your that part with one I suggested as <strong>You commented tha SCK and MISO pins in your code so no data transfer is happening on those pins.</strong> Secondly I made changes according to your hardware configuration as well.</p>
