Hi.
I have this problem:
My Xperia Z5 have grey stripes and dont response any, only are ON , but dont response more than off/on.
Any people help me?
Hi @LUFFY_1983,
I'm sorry to hear this. 
This does sound like it is related to your devices hardware. What I would recommend is that you perform a software repair using Xperia Companion to rule out that anything software related is causing this behavior.
If there is no change I recommend that you get in contact with your Local support team for assistance with having your device sent in to an authorized service center for repair.
Let me know how it works out. 
Hi again!
I send to the company that i buy, they send to official support But the Phone not opened, only tell in the Bill "unrepaired"....not opened, not try....sad.
I use Sony companion to reset the Phone and nothing, are sale that the beginning....
Any idea?
I'm not sure I understand what you mean. You had your device sent in for repair but it wasn't repaired?
If you are still experiencing this behavior with grey stripes after doing a software repair it is most likely related to your devices hardware. I can only recommend that you get in contact with your Local support team and explain the situation to them once again.
