My laptop toshiba screen is not fuctioning

Question

I have a toshiba laptop Model: A305-S6898 that I bought at Best Buy 2 weeks ago. Everything was working fine until last night when i tried to use it. When I turned it on it statrted as usual and then the toshiba logo popped up normally, then it just went blank. I cannot log in or nothing. I've tried taking out the battery a putting back on. Also, I have turned it on and off several times without luck. Please help!!!
