Hello, I'm a newby. I'm sure that will be painfully obvious soon... I have a Lilygo ESP32 T-Display V.1.1. Which i sent a hello world program to. Now, the screen is black and only the blue power on light stays lit, but nothing else works. I have hard and soft reset using ESPTOOLS and power reset, but nothing returns it to default. I can connect via terminal and i can send a SimpleTime.ino to it successfully but nothing shows on the screen.

Is there another procedure to recover the factory defaults?

Thanks in advance
