Finally, I managed to make it work, the problem was the pi zero, it was giving only 3v to the screen. I tried with other pi zero and it works perfectly when I use raspbian. I tried to use RetroPie (I want to create a portable console) but I don't manage to make it work, when I execute the installer I get an error saying that /boot/tmp.dts does not exist and FATAL ERROR. Any ideas about this? Thank you and have a nice day.)
