Hi,
I just got the 2.8" TFT (part no. 1947) delivered and after plugging it into my Arduino Uno R3 board, I only see a white screen.
I've installed v1.10.12 of the Adafruit GFX library and v1.5.9 of the ILI9341 library and when trying any of the examples I see output on the serial console but the TFT display stays white.
I believe this should work out of the box w/o any changes needs to the shield. Is it busted?

@adafruit2, please find images attached. No soldering involved since this is an Arduino Uno R3.

ok please run an i2c scan and post the output, that will test power/tft connection
