Translation via Google translate:

Good Morning.
 
Suddenly this z5 I have started to do white and gray stripes and I can not do Hard Reset or handle it in any way.
 
Any idea to fix it?

Buenos días.

De repente este z5 que tengo empezó a hacer rayas blancas y grises y no puedo hacerle Hard reset ni manejarlo de ninguna manera.

¿Alguna idea para repararlo?

I don't understand what I'm assuming to be spanish, but I've got the same issue with my z5, but rather coloured(blue, red, green) lines.

it's happened after I dropped it in water

I used Google Translate to find the meaning of your message. Kindly post your future questions/feedbacks in English so we can assist you, this is an English based forum.

In your case, I'd suggest that you perform a software repair using Xperia Companion. This can be done while the phone is TURNED OFF and charged. This will do a clean installation of the latest firmware and will also wipe your internal memory. You'll lose any personal data stored on the internal memory in the process.

If the software repair didn't fix it, then you should contact your Local support as it could be a hardware issue.

Follow the steps given in blue links, and keep us updated.

Translation via Google Translate:

Sorry what did you do to fix it? It happens the same to me too.

Disculpa ¿que hiciste para arreglarlo? a mi también me pasa lo mismo.

I send to official service of Sony and not make nothing, not open or similar, only tell "unrepaired" and send me the Phone.
