Sony bravia screen problem please help !?

i have my sony bravia for almost an year now (will be an year in August this year) and its screen has stopped working,after i returned from a 15 day vacation (note it was working before i left). by stopped working i dont mean that the sources are not outputing and im getting the no signal error. i can hear my set top box and my wii but i cant see them.when i start up the tv i hear the startup sound but cant see the logo even at startup the screen is totally blank.however i can see a faint blue backlight and the display does flicker for 1/2 second or so in a few minutes but is black with a backlight for the rest of the time. please help ! :( im very sad and i i have to get something replaced please tell me asap because it has a 1year warranty and i have to take it in before that
