SONY ERICSON W810I

May be video display chip has got damaged.
You need to replace it through any authorized service center.

When I had the white screen problem, I was about to replace my W810i before I found out about the Sony Ericsson Update Service (SEUS). I used it to fix the firmware inside my phone, even though the phone seemed dead and my computer wouldn't recognize it. You can download the SEUS from Sony's website here:

your mobile need to be reflash take the phone to a mobile center and have it flash or you can do that online at www.topsony.com and this is not a free site

switch off the phone immediatly...remove batteries...and let it aside for a week....then try connecting them..if u still have the same problem..turn u mobile in to a local SE service station
All the best

Happy to help
Have a nice day!
