When i open my k850 it would start normally then after sometimes the display would go black and it wont light up again, i still can call and accept calls but i cant see anything on the display.

that is a hardware should have it opened up and the screen interface inspected, cleaned and reattached if problem persists, then the light Ic responsible for the LCd is gone faulty.they should replace it.

Sony Ericsson K850i Display Problems

hi. first,. SORRY for my bad typing...i know how to fix it, had the same problem earlier this year with the blacklight gone after a bad update, but you can fix it easly yourself without turn it in.

you can goto and download the update and that SHOULD to the trick..

that is a norwegian link. but if you click on the flink that says " Last ned Nå"  you will download the program that will install the new update, you can instal the program in english, so that  is just peace of cake from there.. 

Hope that will fix it :)
