It seems it is in COMA ( I mean software problem). It happens we remove battery during it's active mode (switch on position). You have to reflash it with new version of software. A skilled technician with proper understanding of sony-erric's CID technology can flash it with special tool named SETOOL, CRUSIER, UNI BOW and other good tools. Yes, he will charge u little.

You can take it apart and reseat the flex cable on your sony k750i. They come loose some times and cause a white screen. If that doesn't fix it, you can replace the LCD screen for about 20 dollars.

Download Microsoft Active Sync which may help, I take it that you have also installed the Sony Ericsson software that came with your phone?

With regards to your camera, do you know if the rear cover of the phone has been removed at any time??

If it has then there is a chance that the small switch for the lens cover has been damaged which will stop the activation of the phone.
