Same problem with my Z5. I had to restart by pressing the volume up button and power button. SONY, please rectify in your next update!

Re: Sony xperia Z ultra blank screen

I am now experiencing the same problem. I also have a problem with my USB connection. It is very disgusting that a company like Sony wont have a solution for this... If this does not get resolved for me until the end of this month I will never buy a Sony phone again nor endorse it to any of my friends. Do something about this Sony...

Re: Sony xperia Z ultra blank screen

Got same problem in my xzu c6833. It powers on ok I can hear the bootup sound but nothing on screen. I read somewhere it is a hardware issue and to solve it - you just simply solder a jumper on one very small fuse resistor. But it didn't show that it actually worked.
