Sony Ericsson K800i — phone not getting switched on

i am using Sony ericsson k800i since a year.. i had faced no problem of any sorts before... i love it like hell.. the picture quality was good, sound, looks, games, everything...

a month back a friend of mine who was using a stupid old nokia mobile forwarded me some pics of him through bluetooth.. when i came home and connected my mobile to my computer through blutooth as always, suddenly my phone started getting on and off automatically non stop... i could not click any key on it because it was geting switched on and off without a break of even a sec.. then i swithed off my mobile pressing the switch off button on the top and forgot about it...

after few hours when i pressed the switch on button it is not getting switched on since then... and a small red light is coming from the side of my mobile when i press the switch on button.. i replaced its battery but the condition is same...

i have the photo link of the my mobile- u can see the red light coming.. http://i29.tinypic.com/znk0ia.jpg

i have not given it to any service centre because i cant trust them...
