Thanks everyone for you help 
I found out after 3 days of research, that hdmi_blanking was at fault.
In my config.txt, hdmi_blanking was equal to 1, in fact it should have been hdmi_blanking=0.
Now when not playing the screen goes black, the back light is still on but, whatever, it will be for another research.
