Either the flex cables are bad or the new screen, it could be that the damage was more than just the LCD and perhaps even the motherboard.

What do you advise me to do?

@Dizell

if you have a MHL 5pin cable you could connect it to a screen and then see if the phone its working

Telephone work and bootable but no image on screen

[Dizell]

Oooh you ask about MHL 5pin hdmi ... no i have not

@Dizell
