Well, after discarding a faulty screen, my bad luck goes on. With the new screen, recomended by @Brenda, I have a new problem. It works somehow, but for a second, as shown in the video.

I've reflashed the SD card with no luck. Can anyone give some help?

Can you post a picture showing us all your wiring and power source?

Sure.

I didn't follow the color conventions due to some mess up.
I'm using a 5V 1A power source for the raspberry.
EDIT: Although it can seem that V+ and ground are touching each other, they aren't.

Take off either the black or white and try again.

Already tried and nothing. I also cc both AV1 and AV2 and nothing. I check the wires and the voltage and it's right. Any more ideas?

Is that blue wire ground?
Connect:
5v (red) to PP1
Signal (white) to TV
Ground (black) to TV ground

Do you maybe need to solder a jumper cable?

Nothing at all :/
Anyway, I have another screens incoming. I'll try with them. If it doesn't work, I'll try with another pi.

Is this screen confirmed to work at 5v without modification?
