My Samsung Handycam HD is blurry! Please Help!!?

I got the Samsung Handycam for christmas 2010. So May 19 2011, I videotape my brother throwing a water baloon at his face. But heres the catch, i was far away when i recorded it, so it didnt get wet. i felt it, it was dry. So about... 1 hour later i turn on my camera to work on a youtube video, but IT WAS ALL BLURRY! WTF!?! I tried to put it on auto focus, still blurry. i wiped the lens, still blurry. and when i start the camera it shows the start up screen for 1 minute, then it shows me my blurry view. when i zoom in half way it unblurs. but not really as clear. please help! i dont know what i can do for you, but ill work it out!
