esp32 1.8" TFT ST7735 Blank Screen

Hey everybody, I've been tinkering with connecting my blue ST7735 chip to my esp32. I'm using the TFT_eSPI library, and I've got everything wired up and defined properly in the User_Setup.h file included with it. I based my pin selections off of tutorials of other people doing the same thing and my configuration worked for them. However, none of the examples seem to have any effect on the screen. It doesn't even light up. I was wondering if I should assume the screen is defective (since it should at least light up on startup no?) or if there could be another cause for this.
