Xperia Z1 frozen with blank screen and wont switch off or on

[Seamonkey]

Hi

I tapped the snooze button on the alarm app on my new Z1 this morning and the screen is now blank but has some brightness to it, however I am unable to switch off/ on. The rest switch under the SIM cover also has no effect. Any ideas?

Same problem here, phone goes "black screen" and needs a hard reset. I've had my Sony Z1 for a week, both my wife and friend also have Sony Xperia (model irrelevant). What I don't understand is how EVERYONE is simply content with constantly having to hard reset your devices?? Whose the customer here???
This is not a Z1 problem. I've seen posts with the same issue dating back 12 JUNE 2012. I've never seen Sony acknowledge the issue or give details for a patch or Firmware update to remedy a "known" issue (correct me if I'm wrong).
The Z1 is a great phone.
Please Sony I've spent Sooooooo much mony on this device, Give us a fix

Yup I also had the same problem. Thats why I had to sign up for Sony Xperia Care. Whilst turning off the alarm, the screen blacked out. However, Android OS runs normally.  I repaired it using PC Companion, but to no avail. I sent them an e-mail, and they suggested me to repair it using PC Companion. I am planning to get it fixed from my nearest service centre. A great dissappontment........:smileyangry:

This works for my phone:

"There is a tiny RED button next to the sim tray. Press this button in for a second or two THEN press the power button to turn on the phone. Charge the phone before turning on. "

Thanks for the solution

Press and hold the power button + Volume Up button for

5 seconds > ( Vibration ) Force restart

I turned off the "automatic dim" on display light, and that fixed it for me, but I wish Sony did fix the problem.

the charger what you use in ur car is not the sony charger its an all in one plug in charger... which charges your phone fastly and also harm your phone..  i to had the same problem den while travelling i started using sony poertable charger and only sony charger my problem got rectified.......... it helped me by doing this, use sony charger and sony portable charer it wont harm ur motherboard, while using other charger it may harm ur motherboard by extra watts of currents
