ipod touch has blank white screen

My Ipod touch has a blank white screen. I have attempted to restore and restart. I have also reset. The touch is recognized on my itunes page. It will allow me to eject the ipod. I also put earphones on to determine whether I could hear anything (desperation). I can hear something through the speakers. Not music but kind of like dead air---a little hissing----so I know something is going on. I am confused about what to do or whether that little white screen is the beginning of the end. Any insight into my problem would be much appreciated
