Update I narrowed part of the problem down to the backlight on the display. It seems like pin 8 on my ESP32 is floating - if I short the pins 12 (LED_ENABLE) and 13 (3v3) on the J4 connector on the mainboard, the screen lights up (and sometimes stays lit up). It sounds like the firmware doesn't drive this GPIO correctly? When I measure the voltage on ESP32 pin8, it's consistently something like 0.5V
