Sony Ericsson K850i Display Problems

Hi, My name is Mario and i recently updated my phone's software and now anytime a button is pressed the entire display blanks off completely and nothing can be seen until you wait for the button lights to cut off and go in standby and repress a button again, where you run in to the same problem!

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 www.sonyericsson.com and download the update and that SHOULD to the trick..

http://www.sonyericsson.com/cws/support/softwaredownloads/detailed/updateservice/k850i?lc=no&cc=no

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 :)

If your phone has been updated,did you do it yourself? or a reputable phone unlocker? it seems the flash version has installed wrong.. try reformatting the phone. in the other cases of damage,there is usually very little one can do to repair this apart from new screens etc... you cant expect a damaged phone to put something up onto a broken screen... everything may light up, but its obvious that the screen for whatever reason will not display... this could be caused by damage to the actual screen itself,or trying to flash the phones software has gone horribly wrong...

hope this is of some help to all who have these type of questions

My handphone is Sony ericsson, model K850i. Problem: restarting many times. details: when i press the start (ON) button, it will start and turn off and then it automatically restart and off many...


Yes if the battery terminals are contacting well , if not remove clean battery contact and terminals- then the fault can be the software error. but make sure you reset and clear off all downloads or suspected files that could cause errors.
If after all this the fault stays the software must be reinstalled with help from Sony Ericsson.

Sony Ericsson K850i not switching on


Try reading K850i Firmware Overview.. There are some issues with firmware. Such as random reboots and BROD (Blue Ring of Death) i was recently victimized by this BROD. 037 firmware is the most stable firmware so far.. i would advise you also to downgrade your firmware first until SE releases a new and more stable firmware..

Nothing on the display just a dull orange light.


Why don't you try the SE Website? They will give a program called Updater, or something like it. You will hook up the phone to the computer and it will tell you which OS you have in the phone, if it's already update, it will prompt you if you want to run the update for your phone, just click yes and it should be restore by then.

Sony ericsson k850i wont swich on


I think you have to update your phone with sony ericsson update service. I had the same problem with my k850i. Unfortunately this solution only helped me for about a month before I had to do the same again.. and again..

Finally I went to the shop and complained, and now I have a new phone.
