I recently purchased two 2.2" 18-bit color TFT LCD display with microSD card breakout (ID: 1480)
The products were shipped to me and I received them, and upon wiring them up and trying to display images on them I realized that one of my LCD displays is defective. I was able to verify this because I wired each display the same way and ran the code through them exactly the same, and one of them worked perfectly and the other one will not turn on no matter what. I was wondering what the process was to replace this defective product?
Thank you, and please let me know what's possible.
***I've checked, double-checked, triple-checked. My wiring is correct - the exact wiring on my second LCD display was the same and that display lights up and shows the bmp image file I inserted into it. This is not a wiring issue but a display one.

So you have one display plugged into the breadboard and everything works, pull that display out and put the other in and it doesn't work?

Hi Dave,
Yes that's correct. One display works perfectly fine and as expected but the other one just remains a black screen when I swap it out. I even tried wiring it on a separate breadboard to mimic the circuit of the display that works, and that still hasn't resolved my problem. As you can see, on my Arduino serial monitor the image is being successfully uploaded.
