Maybe you will have to flash the firmware new. This video helped for me: https://www.youtube.com/watch?v=zledBB6UPqE&ab_channel=ShotokuTech

thank shopworker.. i've resolved my problem.. it was a library problem.. regards

I have the same problem. Just updatd the firmware, same issue. I'm using TFT_eSPI library.

In 'User_Setup_Select.h'

commented #include
decommented '#include <User_Setups/Setup25_TTGO_T_Display.h>'

Even the example 'Factory_Test.ino' gives only a black screen. @defaliz any suggestion?

@dmognaschi, your setup works for me...

yes @lewisxhe , it was an hw issue due to a defective device. Thank's for your time! Davide
