Hello,

I am trying building a LCD daylight 3d printer. I am practically a noob about raspberry pi 3 and informatics. I connected the LCD via HDMI and powered but the LCD is not working. When i turn on pi, the LCD backlight turn on but the screen is totally black. If I try to display projector calibration the screen remains black, but if click on "turn off projector" the LCD turn off. Where am i wrong?
On the setup page as "Projector communication type" I use "HDMI Power On/Off".

Please help.

I didn't find the right solution from the Internet.

...yet you start up a complicated DIY activity. I think you should start by reading a lot of books and learn the traditional way because it is not going to be easy to help you unless you can help yourself quite a bit. Anyway, I don't know what is the "LCD daylight 3d printer", never seen such thing.
