I purchased a 5inch touchscreen WaveShark.
I connected it to the board Raspberry Pi3 model B (OS Android Things) and it immediately displayed the contents of the program.
After that, I decided to go into the screen settings with the help of hardware keys.
As a result, the screen goes out and does not detract from the contents of the programs. Simply black screen without backlight.
Can I reset the screen to factory settings? Or how can I solve this problem differently?
Thanks for the help.
