This problem is similar with the issue that Sony EricssonK750i has. What you can try is to remove the battery and SIM for 5 minutes, then put them back. Try to turn on the phone. If the same problem occur, send your phone to the manufacturer and have them upgrade the firmware of your phone. That should fix the issue.

Thank you and good luck!

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..

So if the K850i LCD won't light either the backlight or the LCD itself has gone bad. It is a fairly easy procedure to replace yourself and you can pick up the LCD from ebay for 15-25 dollars.

Here is a guide for it and it also includes links to buy a replacement display:
