I have reset the Adafruit ESP32-S2 Feather - 2 MB PSRAM and STEMMA QT / Qwiic, have reloaded both the example code and my own code and, while the display light turns on, the display remains dark. The code runs to the end without throwing an error. I have also checked all the connections and soldered joints, and they are all good.
Is the display bricked?
