Há um tempo que venho percebendo que a tela não executa os vídeos de certos aplicativos como Instagram de forma satisfatória. imagem treme e dica rasurada. Hoje a tela não acendeu!
I have for some time been realizing that the screen does not run the videos of certain applications like Instagram in a satisfactory way. image shakes and shaved tip. The screen did not light up today!

Sounds strange, as the screen does not illuminate I would suggest a backup using Xperia Companion followed by a software repair using Xperia Companion.
If that fails to fix the issue, I'd contact your Local support for a device evaluation
