Hi mate,

i got the same problem 2 times. you can firmware update and fix your problem. the problem is you can not save your contact numbers and content in phone memory.

if you wish to firmware update you can go to Sonyericsson web site and download Update Service Software and install to your computer.

after install run update service in this time make sure your phone battery fully charged and you may have a fixed Internet connection.

Run update service and select your phone click next then it asking you to connect your phone with cable by press and holding "c" button on your keypad. then it will detect your phone and follow the simple instruction appere. important don't unplug your phone until process completed.

i hope this things will help you.

good luck. Lex

K850i Sony Ericsson phone turned off by itself one day and I haven't been able to turn it back on, all i get is the keys lighting up and the camera lighting up but nothing on the screen.


Hi there.
Please try to ring your phone. If it rings, then there is a problem with the LCD screen of your phone. Maybe wet or loose connections. I suggest that you take it to a technician. Replacing LCD screen is not easy.
Thank you!
